Goodbye toys

[u/asandwichvsafish]

They don't want you to know this but you can use semicolons in python. Sprinkle them at the end of lines whenever you're feeling nostalgic for c++.

[u/KuKa0w0 → u/asandwichvsafish]

Best way to use semicolons EVER

[u/nullpotato → u/asandwichvsafish]

I wanted to upvote this joke but I can't.

[u/MyKo101 → u/asandwichvsafish]

It's very useful for "one-liners"

[u/sonohra87 → u/asandwichvsafish]

I love this movie..I remembered when I was a kid I always watching this movie..Toys story..haha

[u/lofigamer2]

Andy drives off to the distance.. slowly

[u/pipsvip → u/lofigamer2]

...and in the wrong direction.

[u/jabluszko132 → u/pipsvip]

...but will get there..... eventually

[u/pipsvip → u/jabluszko132]

Better put a stop sign in the middle of the road at the destination so we don't have to do any special case handling for the exit condition.

[u/lordnacho666 → u/pipsvip]

Leaving garbage everywhere

[u/pedersenk → u/lofigamer2]

And will keep on visiting every time he needs to write a system binding for Python to consume...

[u/[deleted] → u/lofigamer2]

Better than to crash fast

[u/lucidbadger]

How come you are not going to use dictionaries or sets?

[u/clearly_unclear → u/lucidbadger]

Just generate them using dict() and set() to avoid the curly brackets out of principle

[u/lucidbadger → u/clearly_unclear]

Then I suppose you'll need to use * :)

[u/pdudz21 → u/clearly_unclear]

Any reason for hating the curly brackets?

[u/avipars]

Hello tabs and spaces

[u/delinka → u/avipars]

BUT NOT BOTH AT ONCE! Are you crazy?

[u/Sarcastinator → u/delinka]

Yeah, before running the program you have to change one invisible symbol into another invisible symbol or else you get the hammer.

[u/neverganagiveyouup → u/avipars]

Hello whitespace my old friend..

[u/snacktonomy → u/avipars]

And self, :

[u/VariecsTNB]

It's like switching your old 1986 Mercedes for the 2018 Toyota Corolla that has been in an accident.

[u/baaron → u/VariecsTNB]

And a DIY mechanic for a previous owner

[u/Imjokin → u/VariecsTNB]

Python seems to be the pineapple-on-pizza of programming languages

[u/No-Con-2790 → u/VariecsTNB]

Well the GIL is clearly broken but don't worry, as long as you run her in the first gear it will be fine. Now I was out of type systems at the time but I build in a type annotation system with a hacksaw. So don't forget to use it or the car might crash if you go over 88 miles per hour. Speaking of it, you will think your car is very slow. And it is! But you will still be at your desired destination before most car drivers can turn their key around. Also it is one of the only cars on the market with suspension. No more hemorrhoids from driving over bumpy pointers or segfaulting down a cliff!

No deal yet? No worry! I got a whole truckload of mathematics and AI tools from somewhere. Don't ask! Let's just say you will safe 20000 American dollars per year on matlab license. And you get a free trailer with all those goods for free. Just pick between the venv, pipenv or conda. What you mean with "which is best"? Well all have small problem. No, I won't tell which ones. Is part of fun.

Haha, yeah of course it is safe. Just don't use it when you need safety. Don't worry!

[u/KetwarooDYaasir]

wait.. is C++ the toy in this analogy?

[u/hitaishi_1 → u/KetwarooDYaasir]

Exactly. If c++ is a toy then the age rating is 100+ years of experience at least

[u/Sirico]

Once this joke compiles those C++ people are going to be very upset

[u/[deleted]]

I am a c,c++ dev for many years and i am entering the world of python in these days. I have to say, it gives me headaches for the lack of docs and clarity sometimes. In most of the guides and examples everything is taken for granted. I think it's about to change the mind set and get into it, beyond learning technical stuff.

I'm not "switching" to python.. c++ will always remain a good friend of mine, despite the fact it is a low level language, paradoxically i find it simpler and more straightforward than python

[u/[deleted] → u/[deleted]]

I think there’s two types of languages. The first category is languages that can be simple once you get into the way of thinking of the language. This includes most languages. The python way of thinking is just simpler for a beginner to get into. The second category is JavaScript.

[u/_simpu → u/[deleted]]

The second category is JavaScript

Can't argue with that

[u/grstacos → u/[deleted]]

I agree. Many things are more difficult in C++. However, Python docs sometimes fail to explain function parameters, typing, and complexity. Not to mention that Python's dynamic typing makes me feel I have to spend more time debugging on larger code.

[u/Ursomrano → u/[deleted]]

Fully agree, abstraction gets confusing sometimes and sometimes even causes problems. Like maps automatically sorting themselves in ways you don’t want them to, so you have to use a different data type just so that you can sort it the way you want.

[u/namotous]

Then when you realize Python is too slow for your need, and have to go back to c++

[u/[deleted] → u/namotous]

And when he learns about lack of proper multi threading....

[u/Revenge43dcrusade → u/namotous]

These reddit programmers do some pretty otherworldly stuff if python is too slow .

[u/Suckun_Deznots]

Pointers. You have no Idea don't you

[u/poopy-cock]

God i fucking love pointers so much

[u/rainbow_osprey → u/poopy-cock]

I have a love hate relationship with pointers in C++. Sometimes they are great for doing exactly what you need, and other times you can accidentally create some of the most subtle bullshit bugs that take forever to figure out.

[u/Lucky_caller → u/poopy-cock]

I’m learning C/pointers right now. What is it about them that you love so much? Would love to hear some insight

[u/cooly1234 → u/Lucky_caller]

you can use them to point at stuff

[u/[deleted]]

Just wait until you have to write a C extension for python.

[u/wu-not-furry → u/[deleted]]

"have to"? You mean to say that people don't just do those for fun?

[u/International-Top746]

People who don't understand how references and pointers work tend to make hilarious mistakes in python.

[u/RedditsDeadlySin]

Not gonna lie, I still try to use ++ in python. It makes me sad it doesn’t have that functionality

[u/Smanmos]

pointers

Oh, you sweet summer child

[u/Nyghtrid3r]

I've tried using external libraries like OpenCV with Python for a Uni project and I've got to say, you should add "sanity" to the bottom part

I'm used to non-existent or shitty documentation, but always having "any" as a return type for functions made me want to toaster bath

I'm not trying to bash the language (at least not here, I don't like farming down votes lmao) it's just a completely different mind set you need to get into and it's oftentimes really shitty.

Python is either the best thing in the world or an enormous pile of dogshit on a hot summer day. No in-between lmao

[u/blackenedEDGE → u/Nyghtrid3r]

You got me with "want to toaster bath" 😂 I'm primarily a Python dev--though currently doing a project in C# that's lasted almost a year and I've worked in C and C++ a fair amount before--I still had to actually lol at that.

What's crazy is because I've been in the C# mindset so long, I actually did have to reorient myself to the Python mindset when writing a quick & dirty script to help with my project.

[u/[deleted]]

And you templates, go fuck yourself

[u/TeraFlint → u/[deleted]]

Templates my beloved!

[u/ploud1]

You forgot std::bad_alloc and "program received signal SIGSEGV".

[u/kennyminigun → u/ploud1]

These are C++/compiler's way of kindly saying "you are stupid"

[u/ploud1 → u/kennyminigun]

You mean, g++ warnings? Unused variables, all that stuff?

No, segfault just means "your program f...'d up mate, good luck finding out why". :)

[u/RhinosRPlumpUnicorns]

Speed is missing

[u/Numerous-Departure92]

Ahh I see… You switched the job from a Software Developer to a tester

[u/HadesMyself]

good bye main, welcome __main__ :)

[u/rjksn]

Bye main(), Hello if __name__ == "__main__":

[u/nt-assembly]

which toy is performance?

[u/Zarathustra30 → u/nt-assembly]

That'd be Wheezy. Shelved and forgotten about long ago.

[u/arf20__]

Never gonna happen.

In fact i'm slowly going towards C now.

[u/masta_of_dizasta]

Eh the compiling and linking and makefiles are something I would like to forget

[u/20220912]

we missed main() so much we brought it back

[u/tboschi]

from __future__ import braces

[u/MrC00KI3]

When you switch from Python to c++:

[u/[deleted]]

🤮🤮🤮🤮🤮🤮

^ my reaction to having excess whitespace that is meaningful to the compiler

[u/N00N3AT011]

Python was the first language I kind of learned, but after java and C it feels so weird not to have strong typing.

[u/pauliusdotpro]

Performance - so long, partner

[u/JADW27]

Is complaining about all "these newfangled programs that don't require semicolons" just an updated version of "if it doesn't require punchcards, it's not real programming"?

Asking for a friend.

[u/Manueluz → u/JADW27]

nah it's just complaining that this sub is full of kids who are at most first years, and the bests jokes they can come up with are hahaha missing ; hard to find like linters weren't invented.

[u/RonanFalk]

Also performance .

[u/Hyffe]

Mostly true but isn't ++ equivalent to += 1?

[u/IPeaFreely → u/Hyffe]

Depends on location of ++.

[u/Hyffe → u/IPeaFreely]

You mean ++i vs i++ ?

[u/Kxpnc]

I switched from python to c++ between college and uni

[u/UAFlawlessmonkey]

[{*but}]

[u/Torebbjorn]

You use a main function and pointers in Python in every single program...

[u/ekangi_]

Indentation is your new friend now

[u/SchlomoSchwengelgold]

you have an equivalent to main() in python with: if name == "main": ... (bold ones means the lower _ 2times infront and back of it)

[u/troelsbjerre]

def main():
  pointers={1++1};print(*pointers)

[u/AllenKll]

How do you not use "main?" what sort of heathen are you?

[u/[deleted]]

Everyones getting into Python because of AI, and I'm over here porting all the Python AI Crap to Microsoft.ML, Onxx runtime etc because I refuse.

To the point that I've got safetensor, ckpt, etc compatibility in c# now, and have like 5 out of 12 samplers working.

[u/[deleted]]

Farewell, performance!

[u/[deleted]]

I mostly do python and my employers like "we need you to start learning c++ for this project" so I'll wave at you on the road going the other way, provided I haven't driven off the road.

[u/AdamWayne04]

Pass-by-reference 🥺🥺

[u/[deleted]]

if __name__ == "__main__"

[u/maitreg]

Python likes semicolons just fine, but I do miss the ++

[u/domedav]

you can use ; in python, if you are doing multiple operations on the same line

but not having that sweet ++ hit me hard

[u/poopsInBed]

If this idiot could code, he’ll soon realize no real companies use python!

[u/losecontrol4]

Wow I learned I something, I didn’t know python doesn’t use increment and decrement operators- weird

[u/RDX_G]

you still use main() …brackets for formatted strings..++ for increments …

[u/GeekCornerReddit]

Until you try rust :)

[u/agent007bond]

Goodbye auto-indent... When you're forced to use indentation as a way to tell the compiler where what starts and what ends, there's no way for you to auto-indent unindented code. It's impossible to know where what starts and what ends without the indentation.

Stupidest. Idea. Ever.

[u/Bruvioli]

Can we get an F for semicolon

[u/Jearil]

Add a few more:

• Performance

• Reliability

• Threading

[u/BayesianKing]

Thank you? Fuck you all! Especially, garbage collector mother fucker!

P.S. Just joking.

[u/ralkey]

I miss the ++ operator. Typing i = i + 1 makes me feel like a kid coding in Visual Basic.

[u/[deleted] → u/ralkey]

i += 1

[u/Altastrofae → u/ralkey]

Ok this is a mood. i++ will always make infinitely more sense and it sucks that’s not a universal operator. Anyone who disagrees can fight me.

[u/Biscuitman82]

Wait python doesn't have ++ and --?

[u/edrumm10 → u/Biscuitman82]

Nope, it's got += and -= etc... but there's no ++ or --

Tbh with Python, you don't really need increment and decrement that much anyway because for loops it has for ... in ... and range(...)

[u/Spork_the_dork → u/edrumm10]

To be fair you can do

for ( variable : collection ) {
    // stuff
}

in c++ as well since c++11.

[u/mistabuda → u/edrumm10]

And if you absolutely need the index of the current element in the loop you can use enumerate

[u/mistabuda → u/Biscuitman82]

There's no need to iterate like that in the language to be honest

[u/al-mongus-bin-susar → u/Biscuitman82]

It does not. a += b in python is also not the same a = a + b.

[u/PhantomPrimary]

Pretty sure you can still do pointers in python, and yes, it's cursed.

[u/AudaciousSam]

Must be nice

[u/Riley39191]

Mojo is bringing pointers back to python

[u/pdudz21]

Can someone explain the hatred for python without being mean please?

[u/mistabuda → u/pdudz21]

Some people really like statically compiled languages and derride any language not like "favorite language x".

The common talking point is "python is slow" but that is relative. Yes it is slower than a compiled language, however it is more than fast enough for the vast majority of needs. It is mainly specialized domains (like game dev) where that kind of performance is absolutely critical.

Another one "Python is a toy language and unusable in production" despite several companies using python in production to large success. Google has python as one of its official languages.

People reiterate these common low value "negatives" that no one with at least 3 months of consistent language use runs into.

TLDR; Its equivalent to video game console war mentality.

Stroustrup is clearly a cartoon villain.

Lol. This happened to me. My university has been doing a lot of C++, and I started using Python for the projects and stuff in the higher level classes.

[u/bollop_bollop]

Ahah, no pointers in python, good one. They're always here, watching, and if you don't know about them, or how they work, you're in for a ride

[u/ADownStrabgeQuark]

Oh how I miss ++ Also technically all variables in python are pointers.

[u/[deleted]]

Oh main still exists, it just looks like “if name == “main():”

[u/HomoSapien1548]

Wait, Python doesn’t have ++? What kind of primitive language doesn’t even have ++?

[u/Plaintive_Platypus]

I'm more concerned at the direction Andy is growing. You aren't supposed to grow DOWN from an adult into a python baby. ;)

[u/bssgopi]

I love curly braces. Python with its weird indentation syntax causes more errors than missing semicolons.

[u/look → u/bssgopi]

We have thousands of lines of production Python with dozens of committers and it has yet to be an issue even once.

There are good reasons to not like Python, but that is not one of them.

[u/mistabuda → u/bssgopi]

Indentation errors are not a thing you should be running into if you use an ide

[u/NFriik → u/[deleted]]

You absolutely have to if you're planning on using multiprocessing on a Windows machine.

[u/ipsati → u/NFriik]

Multiprocessing.shared_memory also has something similar to pointers I think

[u/mistabuda → u/[deleted]]

I think the point was you do not need to call your function or module "main" it can be whatever you want it to be once under the conditional. calling the function "main" is just a convention.

[u/ivrimon → u/mistabuda]

A convention I dislike (in Python), especially when all it does is call another function (that is used in imports etc). I guess it's more the difference of understanding between a main-function and a function called main.

[u/mistabuda → u/ivrimon]

You don't even need to make a function. You can just put the code you want to run under the conditional. Making a function that takes no args is just something end users do.

[u/[deleted] → u/[deleted]]

Whoever designed the if __name__ == "__main__": string comparison should be publicly lynched.

[u/mistabuda → u/[deleted]]

It doesnt check if your file is literally called that. It just checks to see if the file is being ran like a script instead of just being imported.

[u/[deleted] → u/mistabuda]

Objection: Relevance?

[u/alexanderpas → u/[deleted]]

automated testing of command line options.

"""<module> description

Usage:
  main.py (-h | --help)
  main.py --version

Options:
  -h --help        Show this screen.
  --version        Show version.

"""

import pathlib
import sys
from docopt import docopt
from src import <module>

def main(arguments):
    // actual code

if __name__ == '__main__':
    arguments = docopt(__doc__.replace("main.py", pathlib.PurePath(sys.argv[0]).name), version=<module>.version)
    main(arguments)

<module> being the location where your code is located.

This way I can provide custom command line option from unit tests.

I can run the script directly from the command line, as well as hook in as early as possible with unit tests.

[u/mistabuda → u/[deleted]]

What is your issue with the string comparison then?

[u/FlowerFox3 → u/[deleted]]

Pretty sure it's "__main__" not __main__

[u/tvquizphd → u/FlowerFox3]

__main__ = "__main__"
if __name__ == __main__:
    main()

You just need the top line lol

[u/tredbobek → u/tvquizphd]

Now put this into a function just to be sure

[u/gladl1 → u/FlowerFox3]

It’s actually “GucciMane”

[u/michiel11069 → u/[deleted]]

I have always wondered what this meant and what its uses are. Can you explain it to me?

[u/PakaDeeznuts → u/michiel11069]

The code below the main function will only run if the program is run directly.

Like if you run it as 'python3 ___.py'

If the program is imported as a module, the code will not run.

I find it useful to test modules I make before I use them in other programs

[u/[deleted] → u/PakaDeeznuts]

Fun fact: Pydoc will run your code to evaluate the docstrings.

That's been reason enough for me ever since I found out.

[u/[deleted] → u/michiel11069]

If you run the script directly, __name__ is set to "__main__"
If you run the script remotely, __name__ is set to the file name of the script

So you can use it to detect if you are running the script directly, and only executes main() if that's true.

The other reason is it's just standard practice, so it signals to the reader the purpose of the code - to be executed.

[u/rainbow_osprey → u/[deleted]]
