Understanding the defaultdict Type in Python

A common issue that you can face when working with Python dictionaries is how to handle missing keys. If your code is heavily based on dictionaries, or if you’re creating dictionaries on the fly all the time, then you’ll soon notice that dealing with frequent KeyError exceptions can be quite annoying and can add extra complexity to your code.

The Python defaultdict type behaves almost exactly like a regular Python dictionary, but if you try to access or modify a missing key, then defaultdict will automatically create the key and generate a default value for it. This makes defaultdict a valuable option for handling missing keys in dictionaries.
