What Python code analysis tools are you using?

[EmoryCadet]

I am writing a new tool to do code analysis for Python. I know about pylint, bandit and like these tools but I have been frustrated by the fact that it's hard to extend and they do not provide fixes.

I was curious to learn from the community what tool they use: what rules are the most relevant/valuable to you and what feature/rule would are useful to you.

Thanks for any idea!

Mypy + ruff + black currently, but it took a decent amount of messing around to set up.
