Wizard:

This class is a subclass of Hogwarts because it shows that Hogwarts has wizards. The purpose of this class is to provide methods that would relate to a wizard attending the school of Hogwarts. For example, there is a method that tells you what house they are in, what type of wand they have, and even how much power the wand has. For more information about the different methods in this class, refer to the comments made in my code.
