Using the collections.defaultdict class to create a dictionary with default values. #pythontricks

Hey Python developers!

Let's say we want to create a dictionary that counts the frequency of elements in a list, but we don't want to initialize the dictionary with default values for each key.

The defaultdict class takes one argument: the default factory function for the dictionary.

In this example, we're using the int function as the default factory function, which means that the dictionary will have a default value of 0 for each key.

And that's it! With just one line of code, we can create a dictionary with default values.

Thanks for watching, and happy coding!
