The Real Python PodcastDiscussing Type Hints, Protocols, and Ducks in PythonThere seem to be three kinds of Python developers: those unaware of type hints or have no opinion, ones that embrace them, and others who have an allergic reaction at the mention of them. Python is famously a dynamically typed language, but there are advantages to adding type hints to your code. This week on the show, we have Luciano Ramalho to discuss his recent talk titled, “Type hints, protocols, and good sense.” Luciano was not a fan of type hints.
