How to use typing in debugging?

Attempting to use * from typing import Generator * or * from typing import Dict * in the code results in an error.

>>> from typing import Generator
Traceback (most recent call last):
  Оболочка Python, prompt 1, строка 1
    # Used internally for debug sandbox under external interpreter

builtins.AttributeError: type object 'Callable' has no attribute '_abc_registry'

When you call the same code in the console, everything is fine.
