PEP 698: Override Decorator for Static Typing
This Python Enhancement Proposal describes the use of a new decorator, @override, which would be used as a type-hint for methods in a sub-class that override a parent’s method. This type hint would introduce a level of safety if the parent method is refactored without corresponding changes to the child method.

好东西，我现在就被mypy这里困扰，这个功能就应该跟type hint一起出来才好。看能不能被accept了，不过估计用上怕是要到python3.12了
