Checkpoint 2:
-A function is like a variable in that it allows you to save code that will be ran everytime you call it.
-Functions can break down big problems by allowing you to run the same thing over and over by just calling it. An example would be coding a house. This chould be accomplished by making a door function, triangle function, and rectangle function which could be used for the walls and smaller rectangles that could be used for the windows.
