Add __pycache__ to gitignore

[autinerd]

Proposed change

This adds the __pycache__ folders to the .gitignore. Currently, the *.pyc files are in the gitignore, but the __pycache__ can contain other files, so this adds the whole __pycache__ folders.

Thanks @autinerd!

I'm curious as to how this came up and why no-one else has needed it yet.

Either way I don't see it causing a problem.

So, __pycache__ is solely meant for storing compiled bytecode (the famous *.pyc files).

However, those files are already ignored/excluded. Thus you'll end up with an empty folder. As git only tracks files and not folders, it means there is nothing to track.

Excluding __pycache__ seems thus an odd move, especially considering there hasn't been a known occurrence in all those years, nor do we ignore it like this in our projects I've quickly checked on all systems I can access, but haven't found any other occurrence.

You wrote:

can contain other files

Which ones? And when did this change?
Could you add some context to this?

Here is an example of a file not caught by current .gitignore settings: 44f713d

Edit: this was in PR #115857, but caught be the reviewer thankfully.

Checked with @autinerd on Discord:

I experimented with pylyzer and erg, and they put their cache files into pycache

That is what I was looking for, thanks! 👍
