Libraries not working properly in Python?

Question

Python

I write import asyncio (I use Pycharm), everything is fine, it itself shows that there is such a library
But when the food is asyncio.get_event_loop(), etc., Pycharm highlights in yellow, and the interpreter gives an error
AttributeError: module 'asyncio' has no attribute 'get_event_loop'
Same goes for other libraries like threading
Why is that?
