A python class that acts like dict

Question

I want to write a custom class that behaves like dict - so, I am inheriting from dict.

My question, though, is: Do I need to create a priva

Answer 1

Don’t inherit from Python built-in dict, ever! for example update method woldn't use __setitem__, they do a lot for optimization. Use UserDict.

from collections import UserDict

class MyDict(UserDict):
    def __delitem__(self, key):
        pass
    def __setitem__(self, key, value):
        pass
