The Importance of Default Dict in Python

Python has many data structures that can help you to make your code easier to understand. The default dict is one of my favorite ones, and the one I probably use most on my code. It's a dictionary that basically initializes the value of a given key to something that you can pass in as a function. And then whenever you would like access a given value for a key, an addiction, it will have created an empty list if there has been no value in it already.
