>I don't know how other IDEs behave, but VScode + the Python extensions try to infer the missing hints and you end up with beauties such as `str | None | Any | Unknown`, which of course are completely meaningless.
Are they correct? If they're correct (even though they are a superset of the actual intended type) then what's the problem?
At worst, it's like not having type checks for that particular package.
They are verbose but correct. I've caught some errors this way.
I usually don't think of None as a potential return value (= voids in C) but the LSP code analysis usually picks up on code paths that don't return a value.
I don't find Python's typing valuable for Jupyter type explorations, but they're immensely valuable for catching little issues in production code.
