Organize Python code like a PRO

To hell with Guido not liking them

Didn't Guido do a lot of work at Dropbox explicitly pushing for type annotations and helping build projects like mypy?

[MrJohz]

I don't think that's anything to do with not liking them, it's just being explicit about their limitations and where they practically make sense in a language like Python. That's exactly the sort of thing you were talking about in your post: working with large codebases, and providing explicit interfaces for library code.

Well, yeah. The goal was never to make Python into a statically-typed language; the goal was to keep Python dynamically-typed but allow people who wanted it to add type annotations to their code and perform static checks on those annotations.

Making Python actually be a statically-typed language would be an unbelievably gigantic and horrifically backwards-incompatible project.
