Python annotations (type hints) the typing module --> https://docs.python.org/3/library/typing.html mypy python module enforce static typing

2. MonkeyType (MonkeyType collects runtime types of function arguments and return values, and can automatically generate stub files or even add draft type annotations directly to your Python code based on the types collected at runtime.) https://github.com/Instagram/MonkeyType
