The dictionary class gives us an easy way to do that, and the defaultdict class makes it even easier by declaring an object that uses integers as the default value type. So my code starts by declaring a new defaultdict, and I tell it that I'm going to use integers as the value types, and then I just process each event in the earthquake data in a loop. And I use the event type as the key into the dictionary and I just increase the count for each type as I come across each type of event.
