Python caches every imported module is
import sys import typing sys.modules['typing'] # <module 'typing' from '/usr/local/lib/python3.7/typing.py'> len(sys.modules) # 637
You can reload any module with
importlib.reload to force it to be executed again. Be careful, though, since every object from the module will be recreated, you can break all
isinstance checks and have hard times with debugging it.
old_list = typing.List old_list is typing.List # True importlib.reload(typing) old_list is typing.List # False
