Colleague: "Python is slow..too much slow."

Then I look at the code:

Eight nested for loops, inside two of them, two function calls and three list comprehension. That function has 2 nested loops and two "objects.all()" Django method, plus a list comprehension too..

Yep, Python is slow.

How to order a list in Python

Yesterday was Friday the 13th, so here is a list of my worst dev nightmares without order of significance:

1) Dealing with multithreaded code, especially on Android

2) Javascript callback hell

3) Dependency hell, especially in Python

4) Segfaults

5) Memory Leaks

6) git conflicts

7) Crazy regexes and string manipulations

8) css. Fuck css.

9) not knowing jack shit about something but expected by others to
produce a result with it.

10) 3+ hours of debugging with no success

Post yours

Boss:(pastes a bunch of Python code in Slack)
Boss: Need to convert a long list of ints to a comma separated string. Can you finish it for me? Need it now, I'm in a hurry!!
Me : (Delete all boss's code)
Me : input=[1,2,3,4,5,6,....] output=",".join(str(e) for e in input)
Boss: Damn you! Thanks. Brunch on me today.

The exact moment when I understood what programming actually was.

I was getting hard times at my 3rd college grade, trying to implement the recursive sudoku solver in python. Teacher spent a lot of time trying to explain me things like referential transparency, recursion and returning the new value instead of modifying the old one and everything related. I just couldn't get it.

I was one of the least productive students, i couldn't even understand merge sort.

I was struggling with for loops and indexes, and then suddenly something clicked in my head, like someone flipped a switch, and i understood everything i was explained, all at once. It was like enlightenment, like pure magic.

I had sudoku solver implemented by the end of the lecture. Linked list, hash map, sets, social graphs, i got all of these implemented later, it wasn't a problem anymore. I later got an A for my diploma.

Thank you @dementiy, you were the reason for my career to blast off.

Man, I think we've all gotten way too many of these.

Normally most interactions that I have are through email. Eventually some would try to contact me via phone. These are some:

"Hey! We are calling you from <whatever company name> solutions! (most of them always seem to end on solutions or some shit like that) concerning the Ruby on Rails senior dev opportunity we were talking about via email"
<niceties, how are you doing, similar shit goes here...eventually>

So tell us! how good/comfortable would you say you are with C++?"

Me: I have never done anything serious with c++ and did just use it at school, but because I am not a professional in it I did not list it in my CV, what does it have to do with Rails?

Them: "Oh the applications of this position must be ready to take in additional duties which sometimes happen to be C or C++"

Me: Well that was not anywhere in the offer you sent, it specifically requested a full stack Rails developer that could work with 3 different frontend stacks already and like 4 different databases plus bla bla bla, I did not see c++ anywhere in it. Matter of fact I find it funny, one of the things that I was curious about was the salary, for what you are asking and specifically in the city in which you are asking it for 75k is way too low, you are seriously expecting a senior level rails dev to do all that AND take additional duties with c++? cpp could mean a billion different things"

Them: "well this is a big opportunity that will increase your level to senior position"

Me: the add ALREADY asks for a senior position, why are you making it sound that I will get build towards that level if you are already off the bat asking for seniors only to begin with?

Them: You are not getting it, it is an opportunity to grow into a senior, applicants right now are junior to mid-level

ME: You are all not making any sense, please don't contact me again.

=======

Them: We are looking for someone with 15 years experience with Swift development for mobile and web

Me: What is up with your people not making these requirements in paper? if I knew from the beginning that you people think that Swift is 15 years old I would have never agreed to this "interview"

Them: If you are not interested in that then might we offer this one for someone with 10 years experience as a full stack TypeScript developer.

Me: No, again, check your dates, this is insulting.

===

* For another Rails position

Them: How good are you with Ruby on Rails in terms of Python?

Me: excuse me? Python has nothing to do with Ruby on Rails.

Her (recruiter was a woman) * with a tone of superiority: I have it here that Python is the primary technology that accompanies Rails development.

Me (thinking this was a joke) : What do you think the RUBY part of Ruby on Rails is for? and what does "accompanies Rails development" even means?

Her: Well if you are not interested in using Rails with Python then maybe you can tell us about your experience in using Javascript as the main scripting platform for Rails.

Me: This is a joke, goodbye.

====

To be fair this was years ago when I still didn't know better and test the recruiters during the email part of being contacted. Now a days I feel sorry for everyone since I just say no without even bothering. This is a meme all on itself which no one has ever bothered to review and correct in years for now. I don't know why recruiters don't google themselves to see what people think of their "profession" in order to become better.

I've even had the Java/Javascript stupidity thrown at me by a local company. For that one it was someone from their very same HR department doing the rectuiter, their shop foreman was a friend of the family, did him the service of calling him to let him know that his HR was never going to land the kind of developer they were looking for with the retarded questions they had and sent him a detailed email concerning the correct information they needed for their JAVAscript job which they kept confusing with Java (for some reason in the context of Spring, they literally wanted nothing with Spring, they wanted some junior to do animations and shit like that on their company's website, which was in php, Java was nowhere in this equation)

I think people in web development get the short end of the stick when it comes to retarded recruiters more than anywhere else.

I'm not even that old and I've had it with young cocksure, full of them self language/environment evangelists.

- "C# is always better than Java, don't bother learning it"

- "Lol python is all you need"

- "Omg windows/linux/mac sucks use this instead"

The list goes on really, at some point you have got to realize that while specialization is great, you have to learn a little bit of everything. It broadens you horizon a lot.

Yea, C# does some nifty stuff, but Java does too, learn both. Yea I'm sure Linux is better for hosting docker containers, but your clients are on mac or windows, learn to at least navigate and operate all three etc. Embrace knowledge from all the different tech camps it can only do you good and you will be so much more flexible and employable than your close minded peers :)

Hell even PHP has a lot to teach us (Even more than just to be a bad example, har har)

GOD FUCKIN DAMMIT
I WILL FUCKIN KICK YOU ON YOUR FUCKING THROAT.

Programming Languages and Linux groups in facebook are a fuckin pain to watch.

Some people make groups so all can benefit and help each other, talk about mutual interests, BUT NO SOME FUCKERS WILL SPAM SHIT AND MAKE YOU WANNA SMACK THEIR FUCKIN HEAD.

THERE IS A FUCKIN FAQ SECTION THAT ANSWERS ALL THE FUCKIN NEWBIE QUESTIONS. WHY THE FUCKIN HELL YOU SPAM IF YOU HAVE NO FUCKIN CLUE WHAT THE HELL YOU ARE DOING?

You come to a python group and ask if it's possible to get context from a site. I'M NOT MENTIONING THE FUCKIN FACT THAT THIS IS A SIMPLY FUCKIN QUERY TO A SEARCH ENGINE ALSO IT'S MENTIONED IN THE FUCKIN FAQ. Let's move on. We tell you yes, there is BeautifulSoup for that. After 5 fuckin mins YOU COME AND MAKE A NEW POST THAT SHOWS YOU CANT FUCKIN ITERATE A GODDAMN FUCKIN LIST. I'm not pro either, i don't forbid you to learn, BUT FUCKIN LEARN THE BASICS THAT ARE PROVIDED TO YOU FROM GREAT FUCKIN RESOURCES BEFORE TRYING TO ATTEMPT SOMETHING MORE COMPLICATED. AND IF YOU NEED HELP PROVIDE CODE THAT WE CAN USE. NOT A FUCKIN PHOTOGRAPH FROM YOUR MOBILE

Let's go on the Linux groups.
SINCE YOU FUCKIN JOIN A LINUX GROUP YOU ARE SUPPOSED TO KNOW WHAT THE FUCK IS LINUX. IT'S A FUCKIN OPERATING SYSTEM RIGHT?
Then you spam shit like, UBUNTU OR MINT 5 MINUTES AFTER SOMEONE ELSE MADE THE SAME VERY QUESTION 30 MINS AGO. WHICH WAS ANSWERED AGAIN YESTERDAY.

"What are the benefits of Linux". NONE YOU TWAT, IF YOU NEED ME TO TELL YOU THE BENEFITS OF THE SYSTEM THAT YOU USE THEN WHY THE HELL YOU BOTHER.

Next.
You say you have problems setting up XAMPP. We tell you that since you are on linux better use LAMP. You ignore us and spam your fuckin problem with XAMPP. IM GONNA FIND YOU AND IM GONNA MAKE YOU CHEW MY FUCKIN SHOES YOU PIECE OF SHIT.

I'm not even mentioning the kali wannabe hackers.

Conclusion:
DO A FUCKIN SMALL RESEARCH BEFORE SPAMMING THE SHIT OUT OF STUPID FUCKIN QUESTIONS. AND IF YOU CANT EVEN SEARCH, LEARN TO ASK IN ENGLISH THAT IS FUCKIN UNDERSTANDABLE SO SOMEONE CAN GUIDE YOU ABOUT WHAT YOU SHOULD SEARCH

OH FUCKIN GAWD IM GONNA THROW MY LAPTOP OUT OF THE WINDOW

That just takes the damn fun out of it.

"In Python, we don't actually use commas unlike many languages. And as I mentioned last time, a tuple is a lot like a list, but it has it's differences. Oh yeeeah! Did I mention the logic behind if/else if/ and else statements?? They're sooo amazing."

During interviews about a month ago my friend and i saw an astonishing girl.we didn't knew her name but we had the interview list containg names of more than 1200 candidates which were selected. Fast forward today we started talking about that day and all of sudden we thought wouldn't it be fun if we used the interview list to find her on Facebook. Around 400 of the candidates were female. Instead of doing it manually i decided to write a python script.
Give script list of names
It will go to all the Facebook profiles which came up by performing a Facebook search though your fb account and take a screenshot of every profile
All of it is done through automations
At the end you just have to look at the screenshots manually
p.s. we failed to find her name. You've to trust me when i say we're not creep😂

I really hate it when online sources aimed at educating people looking to get into programming attack specific languages. I'm ok with them recommending some good starting languages (ex. JavaScript, Python, etc.) but I find it extremely inappropriate and damaging when they list languages they consider "bad." Languages like JavaScript, PHP and Java constantly get called out even though they power a huge chunk of the web and services hundreds of millions of people use every day. IMO it's a huge disservice to tell beginners not to even look at these languages. We should be teaching the language isn't really what's important - it's what you build with it.

Porting over code to python3 from python2 be like:
(Cakechat, in this case)

Day 0 of n of python 3 compatibility work:
This should be _easy_, just use six and do magic!

Day 1 of n:
Oh, true division is default instead of integer division, so I need to replace `/` with `//` in a few places.

Day 2 of n:
Oh, map in python2 behaves differently than map in python3, one returns a list, other an iterator. Time to replace it with `list(map())` then.

Day 3 of n:
Argh, lambdas don't evaluate automatically, time to fix that too.

Day 4 of n:
Why did I bother trying to port this code in the first place? It's been so long and I DON'T EVEN KNOW WHAT IS BROKEN BECAUSE THE STUFF RUNS WHEN I BREAKPOINT AND STEP THROUGH BUT NOT WHEN I RUN IT DIRECTLY?!

Day ??? of n:
[predicted]
*gives up*
I've had enough.

As much as I love opensource I hate really hate some of its actvie community members (read this as "freetards" <-- see urbandictonary). As a .Net + web devloper with minimal C experience (I just started learning it) and literally no Python experience its not really easy to contribute for me to many (most) opensource software for linux. I am using some <unnamed software> and I found a <critical bug>, it was easy to reproduce and I wrote for list of possible solutions, found it in a code and linked and basically wrote a docummentation longer than any other I ever wrote for every single project I did ever, combined. This <software> was critical for my server and since owner of github repo and few other people there were really active, I hoped that this bug with pretty good documentation will be solved fast, I went to my bed with a heroic feeling of an open source community contributor that helped saving world. I was horribly wrong. Tomorrow, I got 3 passively agressive responses from owner and other 2 freetards that summed up said <other1>:"oh thats nice, fix i yourself and commit it", <other2>:"have a sex with yourself" in a nice way, and <owner>: "fix my softwate and create mrege request". After replying that I have no experience my Python skills are not on a level requied for such an action, he messaged me on twitter I have linked to my GitHub profile saying even less nicely that I am a "retarded c*nt" and that I should learn Python and fix it myself. This makes me stay with my Windows based Server for some time now, fuck this. I googled his github nickname and guess what. Our main freetard is admin on an <unnamed linux forum> and mebmber of many other "computer help" with literally half of his posts just slightly toxic posts about how everyone should use linux and how supreme it is ober anything other, the other hals was crying why linux has only 1% of market share. Oh boi I am not sure why but ITS MAYBE BECAUSE OF FREETARDS LIKE YOU.
And the funnies thing is, hes not only freetard, he is just fullstack retard. One of his posts is "helping" to some <noob windows user> installing Linux. tl:dr for this las part: Freetard basically wiped all data of that <noob>.

PS: Bless everyone who do not respond "oh nice, now you can do it yourself"

I never had problems with punctuation marks during coding, especially the notorious semicolons because I've always used an IDE, ain't gotta time to waste on compiler errors.

But today I meet my nemesis, a fucking comma wasted an hour of my precious time, causing my unit tests to fail in Python, my unit tests where expecting a list and the actual value is a tuple, it turned out that there was this trailing comma - which I don't know where the hell it came from - at the end of a function call that returns a list.

I only noticed this freaking comma after Pycharm indicated a conflict between the returned type and the expected type and underlined the culprit, that small invisible fucker 😬.

Thank you Pycharm and type hints in Python 3.

this is why, my fellow devs, you have to use an IDE.

PS: For those of you who aren't familiar with python, a trailing comma at end of a variable turns it into a one element tuple.

1, = (1,)

I am interviewing people for a job position with python knowledge.

My first question is how to reverse string and second one what’s the difference between set and list.
So far no one knows.

Fairly speaking I am asking only basic questions about what is decorator, generator, lambda. Also some basic data structure questions.

Is it to hard ?

I lost my faith in humanity.

Wordpress documentation...
"
Hi all, 😎 welcome to wordpress.
Use it as your last resort. Fuck all programming langs. Php is love, php is life."

Oh by the way documentation also says:
"
Wordpress gives you all the freedom you can imagine. Say for instance... You can use any language for server EXCEPT python, ruby, java, c# and many more.[note: Keep looking for the updated list of EXCEPT as new languages come we add it here.]
"
😂😂😂

Python is such a elegant language, but why can't I have an if-clause on a simple for-statement when I can have it in a list comprehension??

[long]
When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.

Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)

It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)

First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.

The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target

All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...

Oh and it should of course be built using test-driven development.

"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.

---

I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.

Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.

I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )

The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.

---

It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.

The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.

The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.

---

Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.

Cheers!

Dropped by my old uni to visit some friends. Met an old classmate who wanted to ask me something about his Python code.

"Oh, no", I thought to myself. "I haven't touched Python in so long, I don't know if I can help, and even then I only knew how to do menial tasks in it!", thinking how to save face and my image of "programmer dropout".

5 minutes later I realized he was mistaking a dictionary for a JSON string, AND was trying to access a dictionary in a list... in a dictionary.

I quietly fixed his print statement which incited an excitement "oh wow, it works!" and quietly returned his laptop. Fun day.

Playing Minecraft minigames.

It's a pictionary clone. One player draws a secret word while the other players have a minute to guess.

Along the bottom is a hint.

Hint is in "_ _ _ l e" format.

Possible word is apple, for example.

I already win half of the games.

I can win more.

Initiate cheating.

Python script that accepts input in same format as hint and returns a list of results based on the word database.

Any time I come across a new word just add it to the database.

Stopped at 69 words tonight.

Game on.

Just to be clear:
I don't hate Zuckerberg,
I hate Facebook.
Always respect a guy who can put money together like it's a python list compression.

Why do job descriptions for ONE developer position, list down ALL the known programming languages, all the web technologies and frameworks available? From java kotlin swift php js jquery node to ionic angular laravel python and what not. Wtf? And this is not one, this is about 70 percent of the job descriptions I see these days!!

So I need to let off some steam, let me know if you think I need to calm down. Personally I'm just having a hard time understanding my team lead.

So I've been trying to update our codebase for the past two months so we run tests against the latest versions of each respective major browser. I've also been trying to cleanup our code and split it into logical modules.

Need I add, according to Bitbucket, I've written over 80% of our code on our 4 projects with 4 team members including myself.

He's out for a week, so I decide it's fine time to get some work done -- which is ridiculous in itself. I finish, add unit tests for crap I missed because he kept shutting down my PRs for shit he couldn't understand.

He tells me on Friday, when he got back, that he'll be declining my pull requests because my code is too complex -- my team lead -- thinks list comprehension and OOP in Python is too complex. Doesn't understand why we need to have pep8 lint tests, or why we can't just export one giant monolithic client package with over 3k lines of code.

Is it worth arguing or should I just let my department head know I can't work on this team anymore? He won't get talked to or fired, he's been at my company for 6 years and he's in the inner circle.

I started my internship at the end of the year..
Fuck my ass!!! This code I have to work with is a huge pile of shit.
The code base I need to work with is around 40k LOC. It is a mixture of C++, C, Java, Python, Bash and I think I saw some lonely js files around.

A list of awesome parts:
- Paths are hard coded.
- Redundant code everywhere
- No documentation or inline comments available

Most of the comments in the code are just old code that is not used anymore. But the cherry on the turd is the class that should provide all kind of useful functions in my daily routine. About ninety percent of the functions have the same description or nothing. Sometimes a function name says "readSomethingFromSomewhere" but instead it writes something to a file. It is really confusing and I need to check everything twice instead of rely on what the function name promises.
I have also learned why copy paste isn't that good. The brief descriptions of every method in a files are always the same.

getName() - Description: Fork child process
getIp() - Description: Fork child process
getIpv6() - Description: Fork child process.

Surprise: None of these functions forks a child process. :D

Another awesome feature is the thing that they store up to five different versions of libraries. Everyone with slight modifications but no hint which one you need to use. Sometimes it is the newest, sometimes the oldest which is running in production. Another case of try and error.
Oh and my dev machine is a potato with a power supply and a fan. I started with NetBeans and every time I compiled the code it sounds like the machine wants to lift off and leave for a better place. (At this point I switched to Emacs and everything runs smoothly now)

At first I thought that I'm just not that good at coding and understanding a big project from scratch but some colleagues have the same problem. The whole system is very inflexible and it is all about "std::cout"-debugging to check if your changes do what you want them to do.

Currently I'm just trying to fix this mess to make the life for the next student or employee easier. The first month was just frustrating as hell. I need to ask so many questions and most of the time the answer was "I don't know, haven't touched this code in years". Needless to say that my progress isn't that awesome but at least I get a nice payment for 20 hours of work a week.

Today on "How the Fuck is Python a Real Language?": Lambda functions and other dumb Python syntax.

Lambda functions are generally passed as callbacks, e.g. "myFunc(a, b, lambda c, d: c + d)". Note that the comma between c and d is somehow on a completely different level than the comma between a and b, even though they're both within the same brackets, because instead of using something like, say, universally agreed-upon grouping symbols to visually group the lambda function arguments together, Python groups them using a reserved keyword on one end, and two little dots on the other end. Like yeah, that's easy to notice among 10 other variable and argument names. But Python couldn't really do any better, because "myFunc(a, b, (c, d): c + d)" would be even less readable and prone to typos given how fucked up Python's use of brackets already is.

And while I'm on the topic of dumb Python syntax, let's look at the switch, um, match statements. For a long time, people behind Python argued that a bunch of elif statements with the same fucking conditions (e.g. x == 1, x == 2, x == 3, ...) are more readable than a standard switch statement, but then in Python 3.10 (released only 1 year ago), they finally came to their senses and added match and case keywords to implement pattern matching. Except they managed to fuck up yet again; instead of a normal "default:" statement, the default statement is denoted by "case _:". Because somehow, everywhere else in the code _ behaves as a normal variable name, but in match statement it instead means "ignore the value in this place". For example, "match myVar:" and "case [first, *rest]:" will behave exactly like "[first, *rest] = myVar" as long as myVar is a list with one or more elements, but "case [_, *rest]:" won't assign the first element from the list to anything, even though "[_, *rest] = myVar" will assign it to _. Because fuck consistency, that's why.

And why the fuck is there no fallthrough? Wouldn't it make perfect sense to write

case ('rgb', r, g, b):
case ('argb', _, r, g, b):
case ('rgba', r, g, b, _):
case ('bgr', b, g, r):
case ('abgr', _, b, g, r):
case ('bgra', b, g, r, _):

and then, you know, handle r, g, and b values in the same fucking block of code? Pretty sure that would be more readable than having to write "handeRGB(r, g, b)" 6 fucking times depending on the input format. Oh, and never mind that Python already has a "break" keyword.

Speaking of the "break" keyword, if you try to use it outside of a loop, you get an error "'break' outside loop". However, there's also the "continue" keyword, and if you try to use it outside of a loop, you get an error "'continue' not properly in loop". Why the fuck are there two completely different error messages for that? Does it mean there exists some weird improper syntax to use "continue" inside of a loop? Or is it just another inconsistent Python bullshit where until Python 3.8 you couldn't use "continue" inside the "finally:" block (but you could always use "break", even though it does essentially the same thing, just branching to a different point).

For those struggling with imposter syndrome, keep a record of your progress.

Break it down into

* used

* learning

* dont need a manual or cheat sheet

* use every day

You can also break it down per project:.

"Project xyz (python: 2 years)"
"Project ijk (js:6 months)".

Etc.

Critically, keep these in something physical, like a notebook or whatever you use *regularly and frequently* to keep notes. That's important because you should be glancing over your progress as a remainder.

Each time you want to add a new line, rewrite your existing progress on a new page, before adding the new line.

So as you flip through the pages you get a large and larger chronological list of your progress, and improvement, and experience.

Add a date to the title for each and a brief note about something that you did or happened on that day or week.

You wont second guess yourself so much once you can see how far you came.

Like at one time I was actually competent at js! (Before I stopped the flash cards anyway).

How I got selected for GSoC'19:
I will describe my journey from detail i.e from the 1st year of the college. I joined my college back in 2017 (July), I was not even aware of Computer Science. What are the different languages of CS, but I had a strong intuition of doing BTech from CSE only?

So yeah I was totally unaware of the computer science stuff, but I had a strong desire to learn it and I literally don’t know why I had this desire. After getting into college, I was learning HTML, Python, and C, also I am really thankful to my friends who really helped me to learn, building logic and making stuff out of it. During the 1st month of joining the college, I got to know what is Open Source, GSoC, Github due to my helpful seniors. But I was not into Open Source during my 1st year of college as I thought it is very difficult to start. In my 1st year, I used to do competitive programming and writing scripts in Python to automate various stuff. I never thought that I would even start doing Open Source development, also in the summer vacations after the 1st year I used to practice programming on HackerRank and learnt an awesome course called Automate the Boring Stuff with Python(which I think is one of the most popular courses for Python) which really helped me to build by Python skills.

Now the 2nd year came, I was totally confused between doing Open Source development or continue with my Competitive programming. But I wanted to know about Open Source development, so I thought to start now will be a good idea. I started attending meetups of OSDC(Open Source Developers Club) which is a hub of my college, which really helped me to know more about Open Source development from my seniors. I started looking for beginner friendly projects in Python on the website Up For Grabs, it’s really helpful for the beginners. So I contributed in a few of them, and in starting it was really tough for me but yeah I continued, which really helped me to at least dive into Open Source. Now I thought to start contributing in any bigger project, which has millions of lines of code which will be really interesting. So I started looking for the project, as I was into web development those days so I thought to find a project which matches my domain. So yeah I finally landed on Oppia:
Oppia

I started contributing into Oppia in November, so yeah in starting it was really difficult for me to solve any issue (as I wasn’t aware of the codebase which was really big), but yeah mentors at Oppia are really helpful, they guided me which really helped me to start my journey with Oppia. By starting of January I was able to resolve around 3–4 issues, which helped me to become the collaborator at Oppia, afterward I really liked contributing to it and I was able to resolve around 9–10 issues by the end of February, which landed me to become a Team Member at Oppia which was really a confidence boost and indication for me that I am in the right direction.

Also in February, the GSoC organizations list was out, and yeah Oppia was also participating in it. The project ideas of Oppia were really interesting, I became even confused to pick anyone because there were 4–5 ideas which seemed interesting to me. After 1–2 days of thought process I decided to go for one of them, i.e “Asking students why they picked a particular answer”, a full stack project.

I started making proposals on it, from the first week of March. I used to get my proposal reviewed frequently from the mentors, which really helped me to build a good and strong proposal.

I must say a well-defined proposal is the most important key for getting selected in GSoC, also you must have done some contributions to the organization earlier which I think really maximize your chances of selection in GSoC.

So after my proposal was made, I submitted it on the GSoC website.
Result Day:

It was the result day, by the way, I had the confidence of being selected, but yeah I was a little bit nervous. All my friends were asking when is your result coming, I told them it will come at 12.30AM (IST). Finally, the time came when I refreshed the GSoC website, Voila the results were out. I opened the Oppia organization page, and yeah my name was there. That was the day I was really happy and satisfied, I was thinking like I have achieved something in my life. It was a moment of pleasure for me, I called my parents and told them my result, they were really happy for me.

I say cracking GSoC is worth it, the preparation you do, the contributions you do, the making of the proposal is really worth.

I got so many messages from my juniors, friends, and seniors, they congratulated me. After that when I uploaded my result of Facebook and LinkedIn, there were tons of comments and likes on the post. So yeah that’s my journey.

By the way, I am writing this post after really late, sorry for it. I must have done it earlier, but due to milestone 1 of GSoC, I was busy.

Have you ever tried chatterbot library (python)?
Last day I tried to train a bot with a list conversation but no matter how long the list was , the bot was really stupid!

Do you have any idea how I can make it a bit smarter?

So I own a small business that is a licensee of about a few hundred other ones. I wanted a mail list from the corporate office and they wanted to charge me. (we already pay them hundreds if not thousands a month) So I wrote a python script to scrape their website and get the info for free. I love programming!

I must learn jQuery and NodeJS. It's amazing the potential of JS. My lastest 10 programs were written in pure JS and I made them in a few hours. As an electronic engineer I hate the high level languages but JS (and maybe Python) it's definitely excluded from the list.

It has been a week now since a co-worker and I started mentoring this intern who joined our team. I have to say it is quite satisfying. His reaction when I told him about lambda functions and list comprehension in Python was gold. I feel good teaching him stuff and the best part is that he's ready to learn, has a brain of his own that he uses and I'm hoping I learn stuff from him too!!!

Here is way to find the element with maximum frequency in a list in Python:

a = [1,2,3,4,1,2,3,4,1,2,3,1]

print(max(set(a), key = a.count))

Why does every Software Engineering role at the top companies never have PHP or any functional languages in it’s list of languages they want you to be experienced in?

It’s always Java, Python, C#, C/C++, Objective C or Ruby. What about Elixir, Scala, Haskell or Clojure?

Python: RandInt(0, 2) generates a random value between 0 and 2. Range(0, 2) generates a list of all numbers between 0 and 1. Boy, there's some consistent syntax.

after beginning to learn numpy , i believe these packages were really created by some clown of a circus xD.
Everything is sooooo entertaining!!!

i learned java 3 years ago, but today if i had to crap out some crazy java or c++ expert , i would tell him about numpy's arrays...
Like , "hey dude python has this cool data structure in the numpy library called arrays, which can hold any datatypes in a kind of arraylist like fashion, and you can convert them from 1 dimensional to 1000 dimensional in just 1 line , and also do you know we can select any column with just array[position]? and even this position does not needs to be an integer, you can use a list , like array[[1,2,3]] will give you elements at array[1],array[2],array[3], and...."
wait, why is my friend dead ? xD
HAhahahaha

I would like to present you the story that I tell everyone who is afraid of expectations, stressed to impress interviewers etc. Story about how I got my first job.

A little of backstory:
I always was good with computers, not like expert, but good. Of course parents were against giving me admin rights, so I just played games or such. When time came to choose my path throgh life, I've chosen to go medicine-related way, and chosen high school with such profile. I did my exams terribly, cause I never cared about marks, so I applied to uni for Information and Communication Technology course. I've learned basics of coding there, much stuff I don't really need right now, but in the end it was the best choice I've made.

With that way too long prologue...

I had to do internship for my uni and decided to try and find some year earlier. There was a lecture about multiplatform coding held by company my uni had partnership with. I've filled a questionare and few weeks later they invited me for assessment - event where they will choose who is good enough.
Of course I didn't believe in my chances to win an internship (1st place got full time job). There were 3 stages:
- solo coding (C/C++ own implementation of list)
- group designing (UML and presentation according to specification)
- interview (talking about code from stage 1, some questions, theory)

I failed 1st stage miserably... so I decided to don't give a shit and bravely presented our group project. A guy asked why we did not included a thing on UML, so I told him that it was not in specification - he was suprised but took it as big +. We "won" that part. When it came to interview... I was myself, cool headed, admited when I don't know things.

I thought that was it.

Few weeks later I received email - they invited me for internship.

They put me into Python project, language that noone in our trainee team knew. Told us 2/4 will be hired. At first I was not interested, wanted to finish my degree. But they convinced me. Now I'm here +2 years.

I am aware there are not many companies like that. Here, the people matters - you don't have to know everything, as long as you are getting along with others.

My tip for you though is: BE YOURSELF, NO MATTER WHAT THEY SAY 🎶

And I wish us more companies like that.😉

Python devs and data analysts....

Do you recommend using pycharm for working with jupyter notebooks? I surely had a bad time with it.

I have been using many jetbrains softwares , and am a fan of their docs search and autocompletion. But I don't think there is a full support for jupyter jn it, because sometimes my graphs made using matploit or seaborn just brakes.

And some libraries have a lot of functions taking parameters as " *args, **kwargs " , I don't know what that means but those function take a lot of "value" parameters i guess?(like this: plt.figure(figsize=[13,6], axis=False) )
Pycharm also don't seem to have access to list of those arguments...

Are you having such problems too? Have you found some better ide with autocompletions and support for jupyter? Do tell.

(Ps: i know jupyter can be run directly on a browser, but as i said "auto completions and documentations" )

If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:

This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...

Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?

Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...

All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).

So what other options are there for making plugins in Go?

There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...

Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...

Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.

Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.

As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...

Have a good night(/day)!

In a mediocre job since last 4 years with just a developer designation, but we simply use Java based tools and products to do most of our job. Need to study for a change in job.

Literally every morning:
"Let me see what to focus on: JavaScript/Java/C++/Python/Data science/ML/AI/NodeJS/...." The list goes on.

Every Evening:
"I need to focus on Data Structures and Algorithms. So let me stick to Java for now."

Next Day:
Back to the same routine.

2 months have passed and I have not seriously studied or concentrated on anything :(

Depressed.

How come your fucking pseudo code is far more complex than python code? You're a fucking university teacher FFS, ALSO TELL ME WHY THE FUCK YOU START YOUR INDEX LIST BY 1.

Writing FizzBuzz in 3 lines via python list comprehentions.

Fuck me sideways, it took me so long to figure out what caused a certain bug. Thanks python

>>> list[0][0] = 1
>>> list
[[1, 0], [1, 0]]

I grabbed 30 random DOS malware samples from my collection, rolled via urand over Python list, and tried to figure out how they work.

Results:

1x zipped EICAR
4x working but effectively useless ("yeah you wiped the first 100 sectors of the drive... but you wrote their prior contents. Literally nothing's changed...")
10x CPU hang
10x crashdump back to DOS
5x crashdump back to DOS but ERRORLEVEL=0 so normal termination despite real errors being given?

also make sure SOURCER is disassembling using 486 or Pentium opcodes or it misses some 286/386 opcodes and will count half the program as data.

An incomplete list of 2018 personal dev goals:

* do more web development (It's fun. In a crude way.)
* finish the smart lamp I started building in 2016 ...
* fix up more electronic devices while learning their inner workings
* learn Python and some other language
* get myself a blog again
* get that testautomation thing which is haunting me in my dreams already to production
* be more relaxed
* do some home automation while not cursing all that much

For a bunch of application redesigns that we are doing at work I am letting the other two developers in my department help with selecting the stack. Normally, we work with Java and PHP, and while they seem to enjoy php I find them concerned at the possibility of making it more Java centric.

So I compiled a list of examples of different tech stacks that are not only more modern (cuz our Java stuff is old JSP stuff) but also simple to learn and use. Mind you, the point is to make this a gradual change, not just rewrite the entire house from scratch.

the list contained examples in:
Python: django and flask

Ruby: Ruby on Rails

Java: Spring Boot

Golang: Small self made mvc framework I built, nothing fancy on it, it uses templates and shit, didn't make it api centric

Node: Express examples in both vanilla JS and TypeScript

php with Laravel.

Since we work with php most of the time as well I imagined that they would be more inclined for Laravel, but I was wrong :P they seemed to like the Node Express route and the Golang route more than anything else with Python and Django being close.

Personally I know that there is more to selecting a stack, but initial perceptions make for a lot of things in selection of the stack.

Pretty excited, if they gauge everything considered in regards to what we have and we found Golang to be a clear winner it would give them the chance to add a nice and competitive tech to their resumes.

not a rant, or anything per se, just wanted to share some stuff with y'all

The Zen Of Ripping Off Airtable:
(patterned after The Zen Of Python. For all those shamelessly copying airtables basic functionality)

*Columns can be *reordered* for visual priority and ease of use.

* Rows are purely presentational, and mostly for grouping and formatting.

* Data cells are objects in their own right, so they can control their own rendering, and formatting.

* Columns (as objects) are where linkages and other column specific data are stored.

* Rows (as objects) are where row specific data (full-row formatting) are stored.

* Rows are views or references *into* columns which hold references to the actual data cells

* Tables are meant for managing and structuring *small* amounts of data (less than 10k rows) per table.

* Just as you might do "=A1:A5" to reference a cell range in google or excel, you might do "opt(table1:columnN)" in a column header to create a 'type' for the cells in that column.

* An enumeration is a table with a single column, useful for doing the equivalent of airtables options and tags. You will never be able to decide if it should be stored on a specific column, on a specific table for ease of reuse, or separately where it and its brothers will visually clutter your list of tables. Take a shot if you are here.

* Typing or linking a column should be accomplishable first through a command-driven type language, held in column headers and cells as text.

* Take a shot if you somehow ended up creating any of the following: an FSM, a custom regex parser, a new programming language.

* A good structuring system gives us options or tags (multiple select), selections (single select), and many other datatypes and should be first, programmatically available through a simple command-driven language like how commands are done in datacells in excel or google sheets.

* Columns are a means to organize data cells, and set constraints and formatting on an entire range.

* Row height, can be overridden by the settings of a cell. If a cell overrides the row and column render/graphics settings, then it must be drawn last--drawing over the default grid.

* The header of a column is itself a datacell.

* Columns have no order among themselves. Order is purely presentational, and stored on the table itself.

* The last statement is because this allows us to pluck individual columns out of tables for specialized views.

*Very* fast scrolling on large datasets, with row and cell height variability is complicated. Thinking about it makes me want to drink. You should drink too before you embark on implementing it.

* Wherever possible, don't use a database.
If you're thinking about using a database, see the previous koan.

* If you use a database, expect to pick and choose among column-oriented stores, and json, while factoring for platform support, api support, whether you want your front-end users to be forced to install and setup a full database,
and if not, what file-based .so or .dll database engine is out there that also supports video, audio, images, and custom types.

* For each time you ignore one of these nuggets of wisdom, take a shot, question your sanity, quit halfway, and then write another koan about what you learned.

* If you do not have liquor on hand, for each time you would take a shot, spank yourself on the ass. For those who think this is a reward, for each time you would spank yourself on the ass, instead *don't* spank yourself on the ass.

* Take a sip if you *definitely* wildly misused terms from OOP, MVP, and spreadsheets.

A crowdsourced curated list of python scripts

I’ve been bashing my head against a project for the past 8 weeks. The project creates a PDF pulling data from multiple APIs, scrapes and private DBs and plots charts using Plotly. We built it with Python, wkhtmltopdf and Celery+Redis. The input is an excel with a list of up to 5 influencers to analyse and compare. Runs on demand on a Linux machine and each report takes around 20 mins to generate. The project has no unittests so the only way I can check everything works is by running a bunch of different inputs. Even though you test 10 inputs (taking you more than a day), there is a high chance something goes wrong on the 11th input. I’m thinking that the only way to fix this mess is to go back to the drawing board and plan yet another refactoring to add unittests everywhere. What do you guys think?

Yesterday I spent almost 3 hours trying to sort an array of objects in java. I'm a person who has written a lot of python and dart code and java is just so daunting. Every simple thing is so complicated.
You can sort a list of objects wrt any parameter using a one liner in python.
Finally after copy pasting a lot of code from stack overflow the thing got sorted. And the worst part I don't even know how the thing works.

Hey, a bit of a dumb question.

When can someone call themselves a "real" programmer? I'm not one to gatekeep and say dumb shit like "iF yOu OnLy KnOw PyThOn Ur NoT a PrOgRaMmEr!", but I guess I want to know when I can call myself one. All I've done so far is make unpolished games in Unity for school that are created only to meet some requirements. I've also worked in my class' team for collaborative Unreal games, which has been painful to say the least. So, when I can stop gatekeeping myself over it? What sorts of experiences should I have? I understand that it's not a list of requirements like my projects are, but I'd like a general idea of when I can call myself a real developer.

Hello.
I am a student of Computer Science Engineering (Bachelor of Technology). I am 3 years into this 4-year course. I am strong in Data structures and Algorithms, and passionate to add more stuff to this list.

I am really done with this University coursework, and want to explore more (specifically, want to do something that is practical, and matters). I, obviously cannot leave the Uni, but I want to make my time at home more productive. Not just to me, but everyone.

But:
1. I don't know where to start.
2. I teach myself everything, and hence, there is much difference between what I know and what people need, and I'm kind of scared of ruining/wasting other's time.

If there is someone out here who has the time out of his/her busy schedule to guide and set me on a path, please do help me. It's getting weird in my head.

Languages I know: C(took a 1-year course), Python, JavaScript [learning JAVA], Oracle, Visual Basic

Things I have done before:
* Developed a fullstack website for Indian Railways (going live in May 2019) [used Python for back end]

I have a sincere need from within to do this, and I am going to learn whatever more I need to, in order to fulfill your requirements. Please just show me WHAT and from WHERE.

Kindly do get back.

Finals will be finally over.

Todo list:
1) Finish Witcher 3
2) Work on Python projects

How long did you spend for witcher 3?
I'm 100 hours into it currently.

Full stack development between Python and JS eventually just makes your eyes cross as you confuse things like object definition syntax, '!=` vs `!==`, `.upper()` vs `.toUpperCase()`, `' '.join(list)` vs `array.join(' ')`

Last year, I made an application of A* maze-solving algorithm in class. I used a linked list and my friends used arrays. Their algorithms were way faster than mine (I remade it later :p).

OK I understand that accessing memory by address if way faster than accessing by iterations, but I also see that python lists or C# lists are really fast. How is it possible to make a list performance-proof like this? Do the python interpreter make a realloc each time you append or pop a value?

Ok finally, I can tell now.

There's a college project I'm in with 2 more people that uses Python and AnyLogic (separately).
We also need to write some LaTeX, so as I was already using PyCharm for the Pyshit, I used it for the LaTeX and for Git.
I used it for Git too because I didn't know how it used Git and was worried that if I used the console it didn't recognize something or glitched out or something. And what the hell, it's a mature IDE, what could be so hard or possibly go wrong?

I had to re download the repo a couple of times because between pushes, pulls, merges and commits something happened and the repo ended in a weird state.
These are all the things I do:
Add, commit, create branches, merge, push, pull and delete branches.

So, I hadn't opened in some time. The last time I tried to bring something from another branch, and stayed up late to finish something. I was waiting for my classmates to join the call when I thought something like "Hey, I should commit what I did until now, it worked great.". When I examined the IDE I found out I was in the middle of a rebase or something. I start clicking buttons to at least try to commit. I press "Skip Commit". I lose everything.

What the fuck‽ As you can see in the comprehensive list above, I never do something similar to a rebase. Apparently when I tried to merge a couple of branches, the stupid IDE thought I tried to do a rebase and never asked me to finish it. Why do something I have never asked? Plus, why haven't you prompted me to finish the operation? That's so stupid. I'm never trusting IDEs again.
I was so lit for losing so many hours of work I did a couple of weeks before, I would have to think it and do it all over again because of something I never asked.

We spent an hour looking for a way to recover the lost code.
Why an hour, you ask, if you can use the Local History for that in PyCharm?
Because none of us had used it before and the articles we found said that you had to open it from the toolbar. From the toolbar it was greyed out.
Then I found the option in the contextual menu of the files. Recovered the LaTeX files but on the AnyLogic files, it was greyed out.
I had to open the Local History of the folder containing the AnyLogic file.
And that was that.

I almost faint.
Fuck Python, fuck PyCharm.

I'm at my Community College as a member of the engineering club requesting funds for a software and hardware-related physical project.

The code was mostly pre-written in Python from a university already, but we needed to build essentially a gaming-level PC to run it, do some welding and metalwork for the hardware, cables, et citera. I don't want to get too detailed in case anyone involved is reading this story.

To get funding, we needed to go before the student senate. I didn't go the first time, but later when we needed more funding for the project to do expansions, we attended.

I came in with a few pages of documentation explaining how the project operated, it's scope, and why we needed the additional $500 on top of the previous $1000 or so spent. I went in woefully behind the times on what a student senate meeting was like.

For starters, I thought this would be somewhat formal, being "Student Senate" in Week 8, and prepared to defend my project fully. Instead, we spent the first 15 minutes going around the table explaining what animal we would be and why, if we had to turn into an animal. It just kept going hilariously, painfully downhill from there.

They did ask some questions about what my project was and how it operated (as not many had seen it), and they wanted explanations even though it was clear absolutely nobody else in the room understood anything. My partner virtually shut down and let me do all the talking for my project and his because he couldn't take the ignorance of some of the questions and the assorted nonsense spread throughout the meeting.

Amazingly, we got funding. We had to sit for the rest of the meeting though, which (among other things) included a segment about whether we should create a new committee called the "Fundamental Insecurities committee" to help out with, well, "Fundamental Insecurities." There was only one member on this proposed committee.

When I brought up the question on why we were making a one-person committee alongside the, like, three one-person committees already in existence, they congratulated me for asking good questions and said I should come more often. They then said the exact same thing again when I pointed out there were better names than "Fundamental Insecurities." It's such a reality check that you are trying to impress people to get funding, when you can't help but feel that everyone is an utter idiot in the back of your head.

Almost a year later, I had to go back with a list of parts we needed. I wrote a whole complex list of things we needed for the project. Even though they tried to ask questions about what certain parts were (to appear like they weren't totally incompetent), and despite asking questions about a bunch of the items, nobody cared about what the $10 for "C418" was (google it if you don't get this joke). I spent about 30 minutes talking with them and succeeded in getting $600 more in funding. We then, to my surprise, spent less than 5 minutes debating whether to send 2 students on a field trip for $700. 30 minutes for $600, for a permanently installed project. <5 minutes for a $700 one-time thing.

And, because this is already a long rant, here's one more thing: The Student Senate's voting rules initially gave everyone who showed up 1 vote. We're all students, we all get a say, right?

Well, I soon put together that Student Senate had fairly low attendance. Engineering Club had high attendance. Student Senate and Engineering Club took place at the same date and time. I then, of course, asked why we couldn't bring the whole Engineering Club into Senate one day, and then proceed to pass an order by simple majority saying that all Student Life funding goes to us.

They then said that the administrators (the heads of Student Senate) could override that, but I pointed out that kind of defeats the purpose of voting in the first place. They then switched script and said they wouldn't do that and would honor such a vote. Shortly after, they changed the rules saying that you only get a vote on your 2nd consecutive visit; and again said I should visit more often because I was brilliant.

You can't make this stuff up.

Hi so I'm learning python in my spare time and I'm in a national competition. I've been told that programming is something my college has always lacked in and in the competition they fortunately use python throughout the problems. I have some example problems used in the last year competition (it was publicly released) and I'm going through them to get an idea of the problems we/I will face. Now I'm still learning python but I understand some of the code at hand. However I still need a little bit of help to understand some of it which will also help me get to a resolution.
Some of the questions I have are:
1. What exactly is the ordinal? I've done some research and I have a small idea but I couldn't find anything to really fill me in and explain how to use it, well in python at least. I saw an example for Pascal but that didn't do much.
2. What is the sys.argv? "The list if command line arguments passed to a python script". I'm not quite understanding that.
3. I know for is used for looping and I know an example say "for a in range(10):" but I'm not understanding the for c in password:
4. Where does the 1000 come from in the builder += 1000.
5. What does the 83 represent after ord(password[1])
6. I know the if statement is saying if this then do this so if __name__ == "__main__":
main()
It's saying call in the function main but where does the name and main come in that part?
Here is the image:

Thank you for your responses in advanced!
One person doesn't have to answer all. Time is precious I understand.

Python list / dict comprehension, one of the numerous reason I truly love python. Simple and powerful abstraction

List of things one of my Python projects needs:

- cross-platform IMA/VFD/VHD/VHDX/qcow/VMDK/IMG/DSK/others image read/extract support that doesn't need admin/root privs (so no, can't use dd or mount)
- custom DB format (for speedups when indexing files and retrieving info based on hash) and converter from previous DB format
- GUI or actually good CLI
- massive speedups

TIL python list variable asignment points to the original instance

I know this isn't reddit but today I noticed that in python when you asign a list variable to another variable in python, any change to the new variable affects the original one. To copy one you could asign a slice or use methods returning the list:

l = [1,2,3,4]
l2 = l
l2.append(5)
print(l)
#Outputs [1,2,3,4,5]

l3 = list(l2) # also works with l2[:]
l3.append(6)
print("l2 = ", l2, "\nl3 = ", l3)
#Outputs l2 = [1,2,3,4,5]
# l3 = [1,2,3,4,5,6]

I wonder how the fuck I haven't encountered any bug when using lists while doing this. I guess I'm lucky I haven't used lists that way (which is strange, I know). I guess I still have a long way to go.

Python list and dictionary comprehension is some crazy awesome black magic. More languages should have these.

TL;DR: I should just stick to Python. I'm not touching front-end stuffs.

I got promoted to moderator of the subreddit of the game I play. Got greeted by a list of task involving tweaking the stylesheet (CSS). I said fine, I screwed around with CSS before I can screw with this again. So now I'm in charge of the whole op. Alone. Yay /s.

The objective is just dark-theme-ing the thing because white hurts (we all know that). So I fired up Firefox, made a test subreddit, cloned the whole stylesheet and sprites and started screwing around with my editor and Inspector Tool. And it hit me: One element refused to render (I don't if that's the correct technical term), and I don't even know why the fuck it didn't render. 15 minutes fuzzing through and it still gave a middle finger. Fine. Fuck you. Full revert, back to original. Then I changed the original sheet one change at a time, reloading after every changes. After changing everything, it suddenly work. What the fuck. Why the fuck. How the fuck. How the bloody fuck. How in the bloody fuck.

(""Fucks" per minute" sure is an effective measure of code quality)

A contains() function for a class to check if there was something in a list. I did not know about the if a in list_b python feature, so I resorted in a loop and a bunch of if/elses.

Dear Python linters, why can't any of you implement some actual linting features? Like, say, consistent use of single or double quotes? Or dict() vs {}? How about indenting nested function calls? Forcing list / set / dict literals as multiline? Trailing commas?

And while I'm at it, why can't you handle dependencies properly? Say, separating linter & linter plugins from the remaining dependencies in a way where I don't have to manually remove them from the requirements lockfile every time?

I am planning on switching to debian, (one of the distros on my "distros-to-try-before-i-die" list.) I downloaded the net install image, what i wanna know is that, what is the average size of the downloads for a minimal.install? By minimal I mean just the bare bones debian with the drivers, python, gcc, emacs, and well i3? Can i pull it off under a gig? (Data limit on my network)

Hello everyone, looking for some career advice here.

First of let me list my credentials off here. I graduated in 2016 with a BS in Computer Science. While I was working on my degree I worked as an engineering for 3 years in a cell phone repair company. What this entailed was managing/reverse engineering a software solution of one of that companies vendors, writing documentation etc (it started as a summer internship and became a job that I worked full time over Summers and up to 30/week in the school year).

Anyway, the vendor I acted as a point of contact offered me a job before I graduated and I started with them in May 2016 as a junior most Dev. Since then I have have maintained the same job tittle (software developer), however my duties have increased.

Currently I maintain several of our build servers, manage software releases (as in I am the lead developer of this application) for the service that makes 90% of this companies money, and am the subject matter expert for everything regarding smartphone diagnostics. I've literally been entrusted with access to all of the company servers for if something goes wrong. I'm also training our newest developers and being told I'm doing a good job at doing so.

Currently with my job on a day to day basis I'm working with Java, Android, C++, Golang, MongoDB, iOS in Objective C, and Python

(Please note this is a small company of less than 50 people)

Currently I'm only being paid 60k USD and am wondering if I should hold out for a raise or consider looking for a better job? ( Please note I live in the east coast in an area where the cost of living isn't absurd).
Because this job was practically handed to me I don't know what to expect and feel imposter syndrome as I think I deserve better pay but think I don't have enough years experience. All advice is welcome

Alright so I'm in need of a little advice.

So I recently decided to go back and practice basic problem solving and from what I can tell now it's just me not used to JS like I am with python but I want to move on to bigger projects and other basic concepts (like manipulation of the DOM) and move away from basic problems.

But my concern is that I'll look at that list and only pick the ones that I feel I understand I can solve instead of the ones I cant. And theres a large list of them and I see that people are doing a lot of them while I'm just doing a few per page. And I'm afraid I'm just not good enough or stupid if I just ignore the basics and move on because the basics are there for you to figure out the easy stuff.

But I really just want to move on and I dont know when I need to. And last time I asked for advice I mentioned I have been programming for a few years, left out the normal accomplishments I've posted on here but I was just told since it's taking me this long I should just quit I tried to rebuttle but they kept telling me no that literally broke me and my confidence so now I'm sensitive to asking questions also fuck whoever that was.

I know a lot of people aren't fans of Microsoft here, but does anyone have some extended experience with using powershell?

I've been using it for creating a script that handles quite a large set of tasks for setting up and configuring some application servers and so far I have been really digging the language. Being able to invoke the script against remote hosts in parallel like ansible has been a really cool learning experience.

Admittedly it's verbose as fuck, so getting the same thing done in something like python/perl might be like half the lines of code. And I know that some of the commands illicit a "WTF?" every now and again. But I think one of the powershell tutorials I watched early on in attempting this helped make using powershell not suck ass.

Every command is basically 'verb-noun'. You don't know what the command or switches are:
> get-help "command" -showwindow

It will give you a list of options if you didn't select the exact command with get-help.

It feels* amazingly buttoned up as a scripting language and it's really cool to be able to take advantage of lower level stuff, like you can run alternative shells (we have cygwin installed on some of our servers), you can run C# code, you have access to interfacing with .NET api's. I haven't messed with anything azure yet, but being able to interface with products and services like SQL/Exchange/O365/azure/servers/desktops from the same language seems pretty cool.

Admittedly, the learning curve feels terrible though. I felt like a dunce for the first couple weeks, couldn't navigate the language at all, and was always in the docs trying to figure stuff out. I think I just needed to understand how the people developing powershell intended for it to be used. Once I was able to put two-and-two together about the verb-noun structure and how to find information/examples about the cmdlets it's been quite easy to work with it.

If anyone else has any extended experience with it, please share your thoughts/opinions. Curious to see if your experiences are/were similar to mine.

If you don't have Powershell experience, please feel free to share your opinions of Micro$haft and me for using Micro$haft products too! It's all good 😎

Went through 60 python packages to see which fails installing on the serve. Took hrs as I have no terminal access but just via jenkins pipeline. So "edit/gitpush requirements.txt and wait" many times. Eventually looped them 1 by 1 in shell. By end of day got the list that installs.
Finally sent the whole list....with confidence
-Takes full 10 mins & Fails......
(panic mode starts)
+Changed the sequence = fails, somewhere else
+1 by 1 again = installs.....
+few random without the culprit =works
+again, whole list = fails, somewhere else

Need to sleep, brain's thinking of eagles

I am planing to create a reading list for technical books and am looking for recommendations.
Currently I have:
- Spark: The definitive Guide (need it for a university project)
- Clean Code
- Clean Architecture
- Functional Programming, simplified (or any other beginner-friendly book about FP)

Do you have any recommendations and must-reads for a more junior developer? I am looking for stuff about FP, Code Quality, Java, Python, Scala, and any general interesting technical stuff.

Just typed this into the Python interpreter and my whole system just froze. Guess I have to do a force shutdown.

x = list(range(1, 999999999))

So is there a way you can somehow configure your linux system such that the window manager/system is never out of memory or processor time? So that atleast I get can atleast kill the process which is freezing the system.

Salt is awesome, no questions about that. YAML is giving me headaches, but it's my fault and eventually I'll get used to it. But this being my first encounter with jinja, WHO THE HELL THOUGHT THIS PIECE OF CRAP DESERVES TO LIVE! Instead of writing python inside {% %} you have to write kinda pseudo python and I just spend over hour trying to build list inside for. Yes, great idea, scoping fors, and lets make it hard to escape scoping, beacause it would be a shame if somebody COULD ACTUALLY DO SOMETHING USEFULL. I though several times of using different renderer, but I want to keep my code readable and mainrainable and in the end I found a workaround, but still, Jinja, YOU SUCK!

!rant but I'd like some advice.

This summer I'm taking a brief course on programming, very generic and mostly just to get it officially on paper, and as of what I can tell a lot of it will be stuff I'm familiar with. Basic syntax, loops, logic, good practices, etc.

However, I get to choose the language I get to work in myself. I assume they have a set of the most commonly used ones (couldn't find a list of them though) and I was wondering if anyone had advice on which to pick?

I already have a base of decent JS and Python, but I feel like it might be good to pick something other than Python? Because even though I love it to bits, I do realize that it's not the optimal language in all situations. What I'm pondering is Java or one of the C-languages, but again, I'm not one of the pros here. Any recommendations?

Lol all my creations are useless to a good extent. I work on them just for practice. Here is a short list of them.
1) c program for every kind of sorting algo
2) stack implementation for checking paranthesis and prefix postfix shit in java
3) Treeview implemention with basic utils like create, update, delete in python

Started learning development 6 years ago with VB on YouTube, after a year I switched to C# and then I got into web development so I started learning html,css,javascript,php and I just add to that list nowadays (nodejs, python, rust, ruby, ...)

In python, is there a way to make this work?

----------
# list of people
people = ["Nick", "Sue", "Bob"]

# class instance
Bob.pockets = ["gum", "paperclip", "coins"]

# convert string to prefix of a class instance
Print(people[2].pockets())

----------

This is the simplest way to show what I'm needing to figure out.

I need to convert a string into the prefix of a class instance.

I'm having trouble figuring it out.

PHP or python, Which is better to create a password list?

What the hell am I!? I wonder if you guys can help me...

I've been programming most of my life but I've never actually been a developer by title or job role. I thought maybe if I list what I do and have done someone here could help? I'm sure there are more of you in a similar boat.

- C# and VB dev for some quick DBMS projects to help me understand and mine databases and create a nice simple view for project teams to show findings from the data to help make certain decisions.
- Automating a lot of my colleagues work with Python and if very restricted then just VBA macros in Excel and MSP. This did also include creating tools to gather data during workshops and converting the data for input into other systems.
- Brought Linux to the office with most team members now moving over to Linux with the peace of mind to know that though they do need to try solve their own problems, I can help if need be.
- Had to learn AWS and then implement an autoscaling and load balanced data center installation of a few Atlassian toolsets.
- Creating the architecture diagrams documentation needed for things like the above point.
- Having said that, also have ended up setting up all the Jira/Confluence etc. servers we use and have implemented so far whether cloud (Azure/AWS) or on prem and set up scripts to automate where possible.
- Implemented an automated workflow view in SharePoint based on SP list data and though in an ASPX page, primarily built in JS.
- Building test systems in PHP/JS with Laravel and Angular to help manage integration between systems. Having quite a time right looking into how to build middleware to connect between SOAP and REST API's, the trouble caused more by the systems and their reliance on frameworks we're trying to cut out of the picture.
- Working on BI and MI and training a team to help on the report creation so that I can do the fun creative stuff and then set them to work on the detail :)

Actually it seems safe to say that it seems that though I've finally moved into a dev office (beforehand being the only developer around) I seem to be the one they go to when a strategic solution is needed ASAP and the normal processes can't be followed (fun for someone with a CompSci degree and a number of project management courses under the belt... though I honestly do enjoy the challenges)

But I always end up Jack of all but master of, well hopefully some at least. let's not even get started on the tech related hobbies from circuit design and IoT to Andoid / iOS and game dev and enjoying a bit of pen testing to make sure we're all safe at work and at home.

As much as I don't like boxes, I'm interested to know if there is in fact a box for me? By the way, the above is just a snapshot of my last two years minus the project management work...

Hey guys!
Once again, I got a little stumped when writing one thingmajig in Python.

I am normally not a programmer (Work as sysadmin), so I don't really know all the fancy abstract ways things are done "properly", which is why I need to ask here:

I have a program, separated into parts. The "core" is a part that sets commandline argument structure (using the argparse library), loads master configuration file, sets up the main logging facility, and then proceeds to load "plugins" - python files with one or more classes that implement one specific abstract class that forces them to implement a common interface of init, run, cleanup functions.

The core then proceeds to initialize those classes, run the "run" function, and run the "cleanup" function.

If the plugin class throws a Warning, it is only logged and runtime continues. If it is anything else, the program logs it and stops.

Now, the issue is, sometimes, a user may want to continue even if a non-warning occurs.

Lets say that I am creating a user, and the user already exists. Sometimes, the program user might want to continue with further plugin execution. And what I was told was to implement specific commandline switches that force continuation of runtime despite the plugin failing.

How should I implement it? The most obvious thing is to add a specific switch for every plugin, but that is exactly what I am trying to evade. I want to have the core as abstract as possible.

Other solution I thought of is to have a file of some sort that would list extra switches to implement, then it would be up to the class to implement if it uses the switch or not (I pretty much pass the entire Namespace received from parse_args() function), but this also feels kinda hackish.

I thought about having some sort of function that the plugin could call in the core to add a new argument, but at the point that plugins start loading, the argument parser is already compiled and cannot be changed further.

Any other ideas of how to re-implement the program are also welcome! I may not do it this times, but I'd at least learn something new again.

So, I just (few hours ago)made a new variable that's either brilliant or innately flawed... not sure yet. It's an oddly unique var...

__bs__

So far I only made it in python and windows env (i script like the methodology of css).

I bet you're wondering how I've defined __bs__ and the practicality of it.
__bs__ is derived from a calculated level of bullshit that annoys me to tolerate, maintain, etc. as well as things that tend to throw nonsensical errors, py crap like changing my strings to ints at seemingly random times/events/cosmic alignments/etc or other things that have a history of pulling some bs, for known or unknown reasons.

How/why did this come about now?

Well I was updating some symlinks and scripts(ps1 and bat) cuz my hdd is so close to death I'm wondering if hdd ghosts exist as it's somehow still working (even ostream could tell it should be dead, by the sound alone).

A nonsense bug with powershell allowing itself to start/run custom ps1scripts with the originating command coming from a specific batch script, which worked fine before and nothing directly connected to it has changed.

I got annoyed so took an ironic break from it to work on python crap. Python has an innately high level of bs so i did need to add some extra calculations when defining if a py script or function is actually __bs__ or just py.

The current flavour of py bs was the datetime* module... making all of my scripts using datetime have matching import statements to avoid more bs.

I've kept a log of general bs per project/use case. It's more like a warning list... like when ive spent hours debugging something by it's traceback, meticulous... to eventually find out it had absolutely nothing to do with the exception listed. Also logged aliases i created, things that break or go boom if used in certain ways, packages that ive edited, etc.

The issue with my previous logging is that it's a log... id need to read it before doing anything, no matter how quick/simple it should be, or im bound to get annoyed with... bs.

So far i have it set to alert if __bs__ is above a certain int when i open something to edit. I can also check __bs__ fot what's causing the bs. I plan to turn it into a warning and recording system for how much bs i deal with and have historical data of personal performance vs bs tolerance. There's a few other applications i think ill want to use it for, assume it's not bs itself.

*in case you prefer sanity and haven't dealt with py and datetime enough, here's the jist:
If you were to search any major forum like StackOverflow for datetime use in py, youd find things like datetime.datetime.now() and datetime.now() both used, to get the same returned value. You'll also find tons of posts for help and trying to report 'bugs', way more than average. This is because the datetime package has a name conflict... with itself. It may have been a bug several years ago, but it beeb explicitly defined as intentional since.

so, I somehow got an interview with NASDAQ for the summer internship this year. somehow it was the only company that had cleared my resume for the interview process, other companies didn't even scheduled one.

and I messed up the first technical interview.

the interviewer asked me to find the largest element in a nested list in python.

for ex [[3,4],[5,2,9],[1,7]] would return [4,9,7]

it was a verbal interview on call and he asked what would I use? Lambda function or list comprehension.

I said lambda function. (I knew it was list comprehension, if I had to code I wouldn't have got confused between the two)

later he asked a couple of questions about linux and boot processes, I could answer some of the basic ones but not after 3rd or 4th question.

now I don't think I have anything to do for summer, as it's a little too late for finding the internships.

any advice?

It's always some dumb thing that goes wrong. Like, a semicolon I forgot to type, or a period or a misspelled variable. Last week I spent two hours on a Discord Bot coded in Python that refused to iterate a list of names. I had forgotten to put quotation marks around each of the items in the list so they would register as strings instead of integers. Will it ever get better?

Just got asked what the difference was between an array and a list in python in an interview for a devops position. Who tf uses arrays in python???? I didn't even know there was such thing.

I want to print the first number in the Fibonacci sequence to contain over 1000 digits. I got fibbonaci to work but I cannot seem to figure out how to implement the "Contain over 1000 digits".

Do I make a list to store the fibbonaci numbers in then do a statement?

My Python 3 Code:

def fibonacci(num):
if num == 2 or num ==1:
return 1
return sum([fibonacci(num - 2), fibonacci(num - 1)])

print(fibonacci(7))

You know I know I don't know all the things that can go wrong... but to me it seems, when you're considering package files.... especially in terms of a build system... you'd just change the install prefix and just archive the files from that after getting the names of shit in a nice list of sorts and make that list queryable, but if you're compiling a package, just take that make install output, and archive it with a descriptor......

why is osb so annoying...
i just want one little fucking package built
to allow the use of microsoft azure python modules.

why is that too much ?

Learning Python from some days back, and have confused about Python Array and Python Lists, please help me to understand this.
Thank You.

Python working non-deterministic on VSCode? That just happened ... somehow, wtf??
Getting a list from a method and comparing its last element with an int value. Always worked before like a charm, didn't change a thing. All of a sudden TypeError, cannot run anymore? Restart VSCode, run again, still not running ... ?? Retry and print the element, in case I've surprisingly actually been an idiot all along ... nope, value looks in print as expected. Continue execution, suddenly condition works again. WTF just happened??? Caching, python extension bug, anything like that to blame?

I am creating a Facebook brute force software... Everything is perfect until it reaches the code that reads the password list.. Then it says no module found for read line!

Python language

How would I use \n in Python as a string?

Use Examples:

If you are making a string calculator, and using \n to separate the numbers/text from each other and put them individually into a list, which the conclusion for example:

24\n10\nhi
This should get a list like this:

[ '24', '10', 'hi']

What is the solution?

We can simply use one of the following solutions:

r"\n"

OR

"\\n"

Code example:

Does anyone know a good way to retrieve back the indexes of elements in the unsorted list after sorting that list in python?
Let's say for example I want to find the largest element in a list, so I sort it and find the last element(as it will be the largest), now I want to retrieve its original position in the unsorted list.
