is there a high quality introduction to Python type checking for people who already know Python?

maybe something very opinionated about how you're supposed to use the features, sort of a "Hitchhiker's Guide to Type Checking".

if I Google around I find either documentation or fairly low quality blog posts.

I like this site for tutorials of just about the right length:

It’s going to be in the next edition of Fluent Python, but that says September release.

Docs and the relevant PEP are your best bet for now.

I honestly think the Pydantic docs are a high quality introduction to type checking in Python.
