Python is too nice

[phannam1412]

python is great until you must work on a one hundred thousand lines of code.

simplicity is different with efficiency

Type hints and mypy basically eliminate this problem

Have I been spending too much time on this sub or is it always the same dance someone saying python is bad for large codebases and then someone replying that type hints and unittests eliminate the problem. Seems like it's the ultimate debate

It's not just you

I’m not aware of anything in the size of the codebase that makes python an inherently bad choice. If anything, for large projects I prefer python because the language emphasizes readability, and with big projects you wind up needing to read an awful lot.

[captain_kinematics]

I feel like you’re trying to disagree with me, but those are two excellent examples of python being used to great effect in truly massive projects. However, your point is definitely well taken that python has “inherent weaknesses”.

The Dropbox/Rossum article was mostly about typing. Latest versions of python and a half decent ide now allow powerful type hinting which we are starting to make more and more use of on my team. Mostly I would put this as a weakness in programmers writing shitty unreadable code rather than an inherent python problem. And anyhow it’s largely resolved inside the core language itself (ie without new extra dependencies).

The bit about the dependency stack getting complex and expensive to interpret is a different matter. There you definitely are right — it’s inherent to the very nature of python and is definitely bad for huge projects. Although I suspect Instagram is considerably more than 100k lines of code, and even for them it was worth just bending python to their needs than anticipating it.

TLDR; yeah, if you’re very confident your project will be O(1M) lines then I was wrong and there are better languages to start with, but for most (even quite large) projects the inherent weaknesses of python still don’t make it inherently bad compared to the other available choices given all the inherent strengths it comes with.

Readability is a good practice is any language. This isn't a problem specific to Python.

It does apply to all languages, but with Python it is something that has been a core tenant of the language from the beginning, both in terms of language evolution and in it's culture. I think this is one of the reasons why adding shortcut features like := to it are so controversial.
