How to properly override the default factory of defaultdict?

I want to pass in the key to the default_factory of defaultdict and I found that defaultdict somehow can intercept my call to dict.__getitem__(self, key), so my class's __getitem__ have to catch a TypeError instead instead of KeyError. The following class is my code: class DefaultDictWithEnhancedF
