My prof suggested me to use matlab instead of Python for my project.

So I started learning and found out that in matlab ARRAYS START FROM 1.

Wtf!

I am going back to python

"Why can't I just get the terminology right in my head"

java: map.
javascript: object?
python: dictionary!
ruby: HASH!
php: aSsoCiaTiVe aRrAy

When you see a Java devotee using Python and they're doing something like this:

array = [1, 2, 3, 4]
for n in range(0,len(array)):
print(array[n])

At least I get to tell them "hey it doesn't have to be so hard just do it like this:"

array = [1, 2, 3, 4]
for n in array:
print(n)

When defining a range, let's say from 1 to 3, I expect:

[1, 2, 3]

Yet most range functions I come across, e.g. lodash, will do:

_.range(1, 3)
=> [1, 2]

And their definition will say: "Creates an array of numbers ... progressing from start up to, but not including, end."

Yet why the fuck not including end? What don't I understand about the concept of a frigging range that you won't include the end?

The only thing I can come up with that's this is related to the array's-indexes-start with-0-thing and someone did not want to substract `-1` when preparing a for loop over an 10 items array with range(0,10), even though they do not want a range of 0 to 10, they want a range from 0 to 9. (And they should not use a for loop here to begin with but a foreach construct anyway.)

So the length of your array does not match the final index of your array.

Bohhoo.

Yet now we can have ranges with very weird steps, and now you always have to consider your proper maximum, leading to code like:

var start = 10;
var max = 50;
var step = 10;

_.range(start, max + step, step)
=> [10, 20, 30, 40, 50]

and during code review this would scream "bug!" in my face.

And it's not only lodash doing that, but also python and dart.

Except php. Php's range is inclusive. Good job php.

Mother fucking SQL, fuck mathematicians, fuck every thing!

So let's supose we'd only need the first char of a string. Every, and I mean fucking every (php, java, javascript, ruby, python, haskell) fucking language, uses something like `substring(input, 0, 1)` as it knows the input is nothing more than a fucking array of chars, otherwise known as motherfucking String. Logically the offset for the first char is 0.

Enter SQL, there you need to put `SUBSTRING(input, 1, 1)` because fuck every one! Fucking math guys who developed relational algebra on which (most) databases are based on (I love you for it, but come on you fuckers!), Decided that the first character should be at position 1...

Fuckers

PHP ist one of the languages I use regularly, but not the main language.
Anyhow, passing an array to a function will create a Copy of the array unless you specifically choose to Pass the reference.
That's seriously fucked up. What other language does that?! Coming from C, Java, Python to PHP I was not prepared to expect shit like that.

Uggg..... I'm trying to encode a binary file in Python which may be an image or may be an executable, and then decode it back into a file (I plan on editing it in the middle, but baby steps for now..) but nothing is working!!

My plan is to:

Open binary file.

Decode as base64, or something else that could easily handle binary.

Convert byte data to string (for editory perpousos - I won't be editing bytes, I'll be doing custom encoding but that's irrelevant for this test)

Convert back to a byte string/array (with .encode(), probably)

Write to file.

I do this, yet the output has been altered... Though I haven't touched anything..

It's so enfuriating.. x.x

Java. AGAIN. 😡

so, I am trying to get a csv opened and read, and then search through it based on values. Easy peasy lemon squeezy in python, right?

Well, damned be java. You need a buffered reader to read the file. Then you have to "while(has next)" the whole damn thing, then you have to do something with the data that you read one by one, right? Well, not to be disappointed, they do have json libraries, but you **have to install** the plugins for it. Aka you have to manually add the libraries or use some backwards manager like maven.

Gotta admit, jdbc is neat if you're anal about your sql statements, but bring the same jazz to csv, and all the hell will break loose.

Now, if you just read your json data into multiple objects and throw them in an array... Kiss shorthand search's ass goodbye, because this mofo can't search through lists without licking the arse of every object. And now, you have to find another way because this way, you can't group shit you just read from csv. (or, I haven't found a way after 5 hours of dealing with the godforsaken shitshow that java libraries are.)

Like, I'm devastated. If this rant doesn't make much sense to you, blame some java library for it.
Shouldn't be too hard.

There was a computer programming teacher in my 1st semester who taught C. He used to have this conventional way of teaching C like other Engineering subjects which was going to more theories before writing actual codes.
These are the conversations with him.
(First day, a guy asks him some questions.)
Guy: Sir, why do we need to learn C? There are other languages used extensively for other tasks like python,etc. Why bother with this boring C?
Teacher: C is used to learn other languages. After learning C, you can easily learn other languages.
Guy: Sir, where is C's application? Where is it used?
Teacher: It is used in academics to lay foundation for students to learn other languages which are used to build softwares.
(Fucking Hilarious)

(A month after he was asking some questions to students.)
Teacher: What is an array? What is an array-name?
Student 1: Array, is this collection of data that can be stored in a single type.
Teacher: Then what is an array-name?
Student 1: I don't know.
Teacher: (angrily) Array-name is a definition itself.
(We were supposed to answer that. It was a standard definition.)

Being a programmer in a scientific discipline can be infuriating.

using "no one" ="almost no one"
using everyone = "almost everyone"

1. No one knows what even the very idea of good practice is. And everyone refuses to learn. 3k lines of repetitive copy pasted main. 500 lines of plotting method.

2. Raw C-style pointer based array creation. Won't use develope array libraries because what if development stops. FUCKING HAVE YOU SEEN YOUR CODE WHAT IF DEVELOPMENT ON YOUR CODE STOPS. FUCK.

3. LOOP VARIABLES DECLARED AT THE BEGINNING OF THE METHOD WHY.

4. Everyone wants to make modular, independent code. No one wants to use OOP. NOPE. ALL IN ONE FILE. WRITE C++ LIKE A FUCKING PYTHON NOTEBOOK. FUCK.

5. LIBRARIES OH MY GOD PLEASE DO NOT CODE UP YOUR MATRIX MULTIPLICATION. PLEASE DO NOT TRIPLE LOOP IT. NO. THE LINEAR ALGEBRA LIBRARY WILL STAY IN DEVELOPMENT.

6. Please realize that literally not one comment over an 1800 line file does not help anyone.

FUCKING. WHY. WHY ARE WE SCIENTISTS SO GOOD AT SCIENCE AND SO FUCKING SHIT AT THE CODE THAT MAKES OUR SCIENCE HAPPEN. WHY. FUCKING. WHY. FUCK.

If you didn't think NodeJS dependency hell was that bad, you should try sequentially parsing a graph that's stored as an array of nodes and their references, where processing of said nodes forces you to use some async functions that depend on other async functions.

What should have been 20 lines of code written in 30 minutes has turned into 3 hours of horror, reading about babel, realizing that it's just adding more problems without solving one, assessing the effort of modification of async libraries to include sync methods as well, trying out asyncwait, async, and everything else there is, trying to rethink the recursive algorithm, rewriting it several times, cursing and hating myself for not choosing to use Python or .NET Core, screaming senselessly at my wife in a language as familiar to her as Klingon, crying in the bathroom, re-assessing my life choices, thinking whether it was a mistake to dedicate 10 years to this career, maybe I'm just not cut out for it since I can't handle this simple task, watching noose tying tutorials on youtube, thinking about my naked empty RPI that won't connect to the server any time soon.

Seriously. Why is it SO BAD?! Or is it just me?

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

Had a job interview today as a Junior Python dev. The hardest part: they asked things, that I used to learn in some time in the past, but got rusty in my memory because I don't use em much. Like "to write func that sorts array". Last time I was writing sorting without standard library at least half a year ago. Same with the regular expressions (need em the most once in several months) or sql expressions (last time - 7 month ago). How to remember these things?

I once interviewed for a role at Bank of America. The interview process started off well enough, the main guy asked some general questions about career history and future goals. Then it was off to the technical interviewers. The first guy was fine. Asked appropriate questions which he clearly understood the answers to.

The next guy up, however, was what I like to call an aggressive moron. After looking at my resume, he said I see you listed C++. To which I said, yes I have about 7 years of experience in it but I've mostly been using python for the past few years so I might be a bit rusty. Great he said, can you write me a function that returns an array?

After I finished he looked at my code, grinned and said that won't work. Your variable is out of scope.

(For non C programmers, returning a local variable that's not passable by value doesn't work because the local var is destroyed once the function exits. Thus I did what you're supposed to do, allocate the memory manually and then returned a pointer to it)

After a quick double take and verifying that my code did work, I asked, um can you explain why that doesn't work as I'm pretty sure it does.

The guy then attempted to explain the concept of variable scope to me. After he finished I said, yes which is why I allocated the memory manually using the new operator, which persists after the function exits.

Einstein then stared really hard at my code for maybe 10 to 15 seconds. Then finally looked up said ok fine, but now you have a memory leak so your code is still wrong.

Considering a memory leak is by definition an application level bug, I just said fine, any more questions?

Unreal Engine adventures:
me: So ok, I need a map from int to String
Unreal: ya but it's called TMap, FCompactPoseBoneIndex and FName.
me: ..uhhh ok whatever
...
me: ok for debugging, please print this
Unreal: FName is not a string
me: k. Fname.toString().
Unreal: ya but it aint a TChar array now
...
IT'S A FKING STRING JUST PRINT IT. And the other guy is still an int with extra steps! Come the fuck on now....
I mean, honestly, a logging function that cannot print a fking FString? sigh...
Man, I miss python and blender...

Well just blew up a coding interview.

Got an offer to be a Drupal dev and was expecting questions on Drupal API and module dev but got asked how to find the closest Enemy in an array and blah blah blah.

Interesting question but man. My mind got blank and got nervous. It's been a while since I've done a question like that and I've been coding for 10+ years.

I would've love to solve that in another language such as Python or C++ but got stuck on PHP because it was a Drupal position. But I only use PHP for Drupal modules and templates who are highly dependant on Drupal API. Or even WordPress plugins. But I try to avoid WordPress because is shit.

Guess the job market hasn't changed since I graduated back in 2014. So I feel a little bummed down. But I guess I'll just have to practice those type of problems as well. At least the problem solving method.

At least it will be an excuse to do those leetcode problems.

How deep does the rabbit hole go?

Unfortunately this shit still didn't work after two hours of debugging, lmao fuck this

I spent the whole day coding in python (usually I code in php or perl) and this language is a fucking joke. C'mon, why everything have to be done in such a weird way? And don't say it's python way because it's bullshit way. Want some examples?

", ". join(str(x) for x in array)
to join array of integers. wtf is that?

True|False
why in hell you need the first letter to be uppercase when your own fucking standard says to use lowercase letters in eg. var names and method names. why?

math.isnan(float(x))
to check if a variable (expected to be integer) is NaN. I won't fucking comment that...

Even prolog don't have such stupid things

"Multiline strings can be used as block comments in Python." Except in some places, where your code will pretty much blow up without any errors, because instead of commenting out a portion of an array, you've just added one big string element. And there's no other way to make block comments. And after actually commenting out every single line, your version control won't know how to merge it anymore, because there are now 100 changed lines instead of 2.

Lets play a little python game together and win some devRant points :

We have an array of integers named L

We need to sort this array so that the biggest number be in the beginning and lowest at the end..descending order

Rules:
-You are not allowed to write more than one line of code in the comment...only one

-if you comment once...you cannot comment directly after that...you have to wait for two other comments after you so you can comment again

-you have to build your code upon the previous comments ... you cannot start from scratch

-the lucky one who puts the final comment is the winner..and we should all ++ his comment to give him the biggest amount of points

Lets start and see who will win :)

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.

Converting javascript/ typescript Map to json
or python date to json

or anything complicated to json is mostly ending with implementing serialization patterns

With date it’s so annoying cause we have iso standards that every language implemented or have libraries

so typescript doesn’t recognize Map<string, string> so you have to convert it to array and then to object

with python you need to make your own serializer / deserializer

So much waste of power usage that if only Greta know it she would say ‘how dare you!’
It can stop global warming.

Been working for almost a year, really hard, on a serious attempt to make GUI development on Python fun, easy, flexible, with a full array of widgets and do it in a way that complete beginners can understand and the professionals will enjoy because it's so easy. My solution is called PySimpleGUI.
My 'rant' is the downvoting and slandering happening on places like Reddit is done by people that haven't tried to use it and most haven't installed it. Yet, they're experts in how sh*tty it is.... even though nothing stated as being a problem is truthful. When asked for more direct feedback on what's wrong, how it can be improved, the active rant threads go silent.
I've never been on devRant, so I hope I'm doing the right thing here! I'm just blowing off steam, not trying to start some holy war.

As a Ruby dev I know I've been spoiled. It's so fucking easy to natively manipulate data in a Ruby app.

But seriously...come the fuck on Python...

You mean to tell me that I have to script out the entire logic to dedup an array?! Something that's an inherent part of EVERY project?

Sorry for the rant, but I just cannot fathom why ANYONE would use Python to write a full application. It's great at scripting, but a shit-stain-to-maintain for true app development.

I want to drop-kick the asshole who decided to write this fucker of an app in Python.

Also, fuck Python for taking ~20 years to add a fucking switch statement.

Any SUPER AWESOME patient... JS PRO that wants to help me with a few problems it would be appreciated..

Okay so I'm having trouble with JavaScript and this can apply to other languages but for now focus on JS. so I'm learning how to manipulate the DOM and I don't really know how to start I picked out a tutorial but I'm afraid I wont learn a lot from it. here are my concerns and yes they don't all have to do with the DOM

> I don't know how to learn without mimicking what the person is doing and when I try something that's related I cant use the related information and techniques because I either don't remember, dont want to do the literal same thing for something slightly different or dont know how and somethings not working even though it should be.

> I do it one way and when people offer to help its just me getting responses of how it could be done completely different and I dont understand why either way should be used

> Why should I have to generate a webpage or div if I can just use HTML5

>whats the difference between JSON and Arrays???????????

>I am not good with arrays, lists, dictionaries, (I'm stretching to python with lists and dictionaries)

>I recently tried the basic quiz project and it was more complicated and fun than I was giving credit for but I want to do it a different way to show myself I learned but I cant because I dont understand how the person managed to loop through the entire array printing the individual questions and answers to the div. like I understand the parts that use the html tags in the code but I dont know how when or what to use it all

>any good javascript/dom resources?

At this point Im just stressing because all I want is a basic skillset with JS but I dont feel like Im learning anything and I dont know how to apply my knowledge or improve upon the programs ive been learning from or trying to make. and arrays have been tripping me up to especially since I have no clue what the difference is between them and JSON and why I should use one over the other and dont get me started how shit I am with manipulating them. FUCK IM STUPID

I'm currently writing a discord bot using the discord.py library and I cannot decide how to structure my code.
I was thinking of writing it in modules, with a core script that would load any valid module class that would include an array of all the event hooks it wanted, whether it wanted to send messages and so on.

It's a nice way to practice python after my last working bot that I wrote in (Sit down for this) PHP using an outdated and abandoned wrapper (Yeah, event-based programming in PHP, I know)

Are there any better ways to do this? I really don't want to hardcode all the functions in, only to have it fall apart later after adding another feature...

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.

Can't seem to get the hang of numpy arrays..irritating the living HELL out of me rn

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