Is Python really that useless? (lemmy.world)

I mean by useless is it's so slow you can't make games or even big projects for GUI, only you can do is AI/ML, Data Science, and basic stuff. I think Rust is better because of its speed and language capabilities?

Was it though? Or is it like other things "written in Python" where all of the heavy work is handled by C libraries?

    I hate this argument on principal, if I write a game with Pygame, it's written in Python not C.

    Balatro is written in Lua not C just because Love uses SDL.

    This is like saying Python, CPP, JS, PHP, LUA, Perl, Dart, C# and Java are just written in C.

    This is like saying Rust isn't a real language because it relies on LLVM which is written with C/CPP.

    If I split the lua code in balatro from the SDL library, I don't have a game anymore.

    Why do you feel a need to be able to claim that something is "written in Lua" or "Python" when it's using native libraries? Many games are using a mix of languages these days. There's no shame in it and I didn't imply there is.

    People get very confused over this thinking that "Python is very fast at number crunching" because of things like numpy which is written partly in C to achieve that performance.

    This is like saying Rust isn’t a real language because it relies on LLVM which is written with C/CPP.

    That's entirely different - I'm not talking about the interpreter or compiler. Just the runtime code.

    Python itself is just a program written in c, every time you do len(string) you are calling out of the python interpreter into compiled c code. The distinction between python wrapped c library and a python lib can be fuzzy.

    That's not what I'm talking about. Things like "numpy" which are actually written with a fair amount of C for performance. Or pandas which uses Cython to trans-pile Python to C to compile.

    It's not "pure python".
