> it was probably stored as a member variable by something 10 callstack levels and 5 classes distant from what you're currently working on If you can define methods on an object dynamically in Python, it doesn't mean that you should. Monkeypatching is not encouraged in culturally in Python. Most often it is seen in tests otherwise, it is rare. Nobody forbids using ABCs to define your custom interfaces or using type hints for readability/IDE support/linting (my order of preference).
