What is the descriptor protocol?

Q: What is the descriptor protocol?

A **descriptor** is an object that customizes attribute access by implementing any of `__get__`, `__set__`, `__delete__`. When a descriptor lives **on a class** and you touch that attribute on an instance, Python routes the access **through the descriptor's methods** instead of just reading a dict: obj.temp attribute access descriptor <text class='d-sub' x='265' y='84' text-anchor
