[Python] python Multidict implementation [closed]

Please review my implementation of class Multidict

https://github.com/oraytman/multidict

class MultiDict(dict):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self._count = 0

def __setitem__(self, key, value):
try:
_ = super().__getitem__(key)
except KeyError:
super().__setitem__(key, [value])
self._count += 1
else:
super().__getitem__(key).append(value)
self._count += 1

def __delitem__(self, key):
self._count -= len(self[key])
_ = super().pop(key)

def __len__(self):
return self._count

def __repr__(self):
return f"{self.__class__.__name__}({super().__repr__()})"


Appreciate if you add PR to make it better

What is the best way to implement method below?

def __delitem__(self, key):
self._count -= len(self[key])
_ = super().pop(key)
