Search - "python lambda"
-
I'm a self-taught 19-year-old programmer. Coding since 10, dropped out of high-school and got fist job at 15.
In the the early days I was extremely passionate, learning SICP, Algorithms, doing Haskell, C/C++, Rust, Assembly, writing toy compilers/interpreters, tweaking Gentoo/Arch. Even got a lambda tattoo on my arm after learning lambda-calculus and church numerals.
My first job - a company which raised $100,000 on kickstarter. The CEO was a dumb millionaire hippie, who was bored with his money, so he wanted to run a company even though he had no idea what he was doing. He used to talk about how he build our product, even tho he had 0 technical knowledge whatsoever. He was on news a few times which was pretty cringeworthy. The company had only 1 programmer (other than me) who was pretty decent.
We shipped the project, but soon we burned through kickstart money and the sales dried off. Instead of trying to aquire customers (or abandoning the project), boss kept looking for investors, which kept us afloat for an extra year.
Eventually the money dried up, and instead of closing gates, boss decreased our paychecks without our knowledge. He also converted us from full-time employees to "contractors" (also without our knowledge) so he wouldn't have to pay taxes for us. My paycheck decreased by 40% by I still stayed.
One day, I was trying to burn a USB drive, and I did "dd of=/dev/sda" instead of sdb, therefore wiping out our development server. They asked me to stay at company, but I turned in my resignation letter the next day (my highest ever post on reddit was in /r/TIFU).
Next, I found a job at a "finance" company. $50k/year as a 18-year-old. CEO was a good-looking smooth-talker who made few million bucks talking old people into giving him their retirement money.
He claimed he changed his ways, and was now trying to help average folks save money. So far I've been here 8 month and I do not see that happening. He forces me to do sketchy shit, that clearly doesn't have clients best interests in mind.
I am the only developer, and I quickly became a back-end and front-end ninja.
I switched the company infrastructure from shitty drag+drop website builder, WordPress and shitty Excel macros into a beautiful custom-written python back-end.
Little did I know, this company doesn't need a real programmer. I don't have clear requirements, I get unrealistic deadlines, and boss is too busy to even communicate what he wants from me.
Eventually I sold my soul. I switched parts of it to WordPress, because I was not given enough time to write custom code properly.
For latest project, I switched from using custom React/Material/Sass to using drag+drop TypeForms for surveys.
I used to be an extremist FLOSS Richard Stallman fanboy, but eventually I traded my morals, dreams and ideals for a paycheck. Hey, $50k is not bad, so maybe I shouldn't be complaining? :(
I got addicted to pot for 2 years. Recently I've gotten arrested, and it is honestly one of the best things that ever happened to me. Before I got arrested, I did some freelancing for a mugshot website. In un-related news, my mugshot dissapeared.
I have been sober for 2 month now, and my brain is finally coming back.
I know average developer hits a wall at around $80k, and then you have to either move into management or have your own business.
After getting sober, I realized that money isn't going to make me happy, and I don't want to manage people. I'm an old-school neck-beard hacker. My true passion is mathematics and physics. I don't want to glue bullshit libraries together.
I want to write real code, trace kernel bugs, optimize compilers. Albeit, I was boring in the wrong generation.
I've started studying real analysis, brushing up differential equations, and now trying to tackle machine learning and Neural Networks, and understanding the juicy math behind gradient descent.
I don't know what my plan is for the future, but I'll figure it out as long as I have my brain. Maybe I will continue making shitty forms and collect paycheck, while studying mathematics. Maybe I will figure out something else.
But I can't just let my brain rot while chasing money and impressing dumb bosses. If I wait until I get rich to do things I love, my brain will be too far gone at that point. I can't just sell myself out. I'm coming back to my roots.
I still feel like after experiencing industry and pot, I'm a shittier developer than I was at age 15. But my passion is slowly coming back.
Any suggestions from wise ol' neckbeards on how to proceed?32 -
I work for a "Visionary" in our org. Motherfucker will use something for five minutes and decided it's the new-hot, and off we go chasing it.
"I did a Python + AWS tutorial last night, I get it. We need to start migrating everything to Lambda today."
A week later he hits his first error message that needs more than five minutes of work to solve and we're moving to a local Haskell stack.4 -
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.15 -
Everyone talks about their hate of js but like python is honestly just as bad.
- shitty package manager,
* need to recreate python environments to keep workflows seperate as oppose to just mapping dependencies like in maven, npm, cargo, go-get
* Can't fix python version number to project I.e specify it in requirements
- dynamic typing that gets fixed with shitty duck typing too many times
- no first class functions
- limited lambda expressions
- def def def
- overly archaic error messages, rarely have I gotten a good error message and didn't have to dive into package code to figure it out
- people still use 2.7 ... Honestly I blame the difficulty of changing versions for this. It's just not trivial to even specify another python version
- inconsistent import system. When in module use . When outside don't.
- SLOW so SLOW
- BLOCKING making things concurrent has only recently got easier, but it still needs lots of work. Like it would be nice to do
runasync some_async_fcn()
Or just running asynchronous functions on the global scope will make it know to go to some default runtime. Or heck. Just let me run it like that...
- private methods aren't really private. They just hide them in intelisense but you can still override them....
I know my username is ironic :P11 -
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).19 -

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!!!

When the "production-ready" "state-of-the-art" deployments engines *cough AWSLambda *cough takes two hours to setup a basic python function for no reason.

Hi there, i'm new to AWS. i've running my python code in Lambda. Basically it's calling an http-request and processing the responding JSON to a CSV file. Now, what is the easiest way to transfer that CSV file to a 3rd party FTP Server?7

Using lambda expression to simplify otherwise large function calls in Python makes me feel warm and fuzzy inside.1

"if compiler can infer this, there is no need to add "x ->" , simply use it" ..AAAGHH FUCK YOUUUUU KOTLIN!! what else should i fucking not write? why do't you take a number of my employee and ask his requirements, maybe add a ShoppingKartApp.kt in your compiler next time? it will be completely inferred when i write "Fuck you" in the gradle.
And fucking companies are promoting this! I wonder how those devs are living there
Person A knows only that lambda is
{name:Type,name:Type->code}, and thus writes a clean code.
Person B comes says "This shit suck", writes "{ acc, i -> acc + " " + i }" ,goes away
Person A : "wtf is this shit? why it works?"
Please for the love of god, follow some rules! My first language was python, i love its zen:
- Beautiful is better than ugly.
- Simple is better than complex.
- Readability counts.
- Special cases aren't special enough to break the rules.
- There should be one-- and preferably only one --obvious way to do it.
- If the implementation is hard to explain, it's a bad idea.
-...
I just wish it follows at least one thing from python's zen : "There should be one-- and preferably only one --obvious way to do it."3 -
Design question for y'all
Context: python lambda
Better to make classes for dictionary objects holding strings between methods
Throw strings around separately

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?10 -
Working on a feature which heavies relies on a data pipeline. I noticed it is a couple of lambda functions calling each other ( Fuck you to the guy who made it). The best way to get sanity back is build a proper etl pipeline. Any suggestions for building a etl in python with reliability.
Options already considered
1. Celery tasks - Worked well but no overview of the single task progress across celery tasks
2. Airflow - Gives good overview but the docs make less sense than a 10 yr talking. Mostly because they introduced a new syntax and not everything has migrated fully yet. Also no support for reusing dags2 -
could anyone help me calculating costs for AWS and Google Colab Services? I find it quite intransparent...
i would like to host 1x Python App which runs once a day or week (API call, enrichment uf JSON, JSON 2 CSV, FTP transfer). runtime is probably a few seconds, something between 1 and 5.
in AWS i created a Lambda function and for scheduling i guess i need CloudWatch. what really grind my gears is the combination of free contingent and paied service - i really don't have an overview right now, so my question here: how could i calculate it and what would be the monthly/yearly costs?
in Google Colab created a notebook and for scheduling i would need Google Cloud Scheduler. as far as i understand the hosting of the notebook is for free and the costs of cloud scheduler is $0.10 per job per project per month. 3 are for free. so 1 project, 1 job = scheduler for free?
Also, i'm open for other services such as digital ocean droplets or similar.
thx in advance for your help!8
