What do you mean you can't trust them? If you write a type hint in your code and then run mypy on it, it will tell you whether the type is being violated. And, PyCharm has a type checker built in that lets you know as you're coding.

Only if the type hints for all the libraries you use are correct (and in practice they're not).

Ah, thanks. I think I am going to give type hints another try.
