I've also had a mixed experience with mypy. Take a look at using pyright for static type checking instead, it's worked quite well for me.

But do write type hints. I recently got thrown into a large-ish project where neither types nor docs where used. Trying to figure out wth a parameter was supposed to be wasn't a pleasant experience for a newcomer. In addition to improving DX, I also believe it's alot more effective in the long run.

I saw how these guys were developing: write code, run code, deal with the runtime crashes they encounter, then run code some more and deal with other unexpected runtime crashes. It would have been a lot faster and more stable if they'd just used type hints and static type checking, as their IDE could've easily found many of these bugs for them immediately.
