Protocols - Static Duck Typing for Decoupled Code

YouTube·EuroPython

Explore the concept of Protocols in Python for static duck typing in this 21-minute conference talk from EuroPython 2022. Delve into how Protocols support static type checking with tools like mypy to verify code correctness before runtime. Learn about the motivation behind introducing Protocols as an alternative to explicitly inheriting from Abstract Base Classes (ABCs), which is considered "unpythonic" according to PEP 544. Discover various use cases for Protocols and gain insights on their correct implementation to create more decoupled and idiomatic Python code.
