Pyupgrade is a good tool that focuses on upgrading to newer idioms. Which is more important for learning than simple pep8 type stuff, which is useful but has its limits.

On that subject, Raymond Hettinger has a great talk called “Beyond Pep8” that talks about how to de-java your codebase among other things. Also reading the book Fluent Python now and it is so far excellent.

And ruff has a bunch of the pyupgrade rules included, which has made it easy for me to start catching things like using List instead of list in py3.10+.
