I can't think of any (small) libraries I could recommend to learn best practices, but what does come to mind is click [0], the CLI library for Python. Their documentation is pretty great, there are tons of short example scripts to be found online, and in my experience making little apps with click can be a nice way to learn different python features like args/kwargs, decorators, string manipulation, etc.

I agree with others that code formatters like black or ruff might be helpful to you. The literature surrounding them, such as PEPs concerning code formatting, often include examples you may find useful.

Beware, the pallets people are decorator supremacists. Everything is a decorator even when it arguably shouldn't be. DDD --> decorator driven development. It's a nice technique, too a point. Only exaggerating a bit. ;-)

I was just going to suggest this. Click is a great code base to learn form.
