Python has had syntax support for type annotations for a while now. The Python runtime doesn't enforce the typing at all, but it can be enforced by a linter or by your IDE. And I believe you can introspect the type annotations at runtime, because they are actually part of the syntax.
There's even an alternative way of doing type annotations through specially formatted comments, just in case you might still need to write code that is backwards compatible with Python 2.

mypyis great, but it doesn't come close to what you can do with TypeScript. I don't think that's necessarily a jab at Python (thoughTypeVar's limitations do come up here and there), more just throwing TypeScript on a pedestal.
