Hi, Kendall Kelly.

Python dictionaries are the equivalent of "objects" in other languages such as JavaScript and Java. Dictionaries allow us to create a structured object so that it can be reused over and over quickly and efficiently.

When making a character we can make instances of the dictionary, rather than remaking each character from scratch.

I found the W3Schools explanation of a dictionary really helpful, see the link below.
