Protocols in Python specify the methods and attributes a class must implement to be considered of a given type.
Protocols are essential for Python's type hint system, enabling static type checking through tools like mypy, Pyright, and Pyre.
They allow for structural subtyping, addressing the limitations of nominal subtyping and enabling static duck typing.
This video course covers understanding protocols, type hints, static duck typing, creating custom protocols, and the distinctions between protocols and abstract base classes.
