List[int] in python

Question

https://code.sololearn.com/czAIgGgL4jka/?ref=app

if List[int] doesn't restrict the list to have only integers, what else does it do?

Answer 1

isinstance() or type()

If I'm correct isinstance() returns also True for subclasses. Type() not.

Answer 2

It is a type annotation, that hints the user how to provide input. IT DOES NOT DO TYPE-CHECKING.
