Title: Modification to introduce functions more gently and differentiate between performing actions and returning a value

As part of the final assignment, this is a small addition to the Functions section of the novice Python lesson. The modifications introduce functions more gently, starting with a simple function that adds two numbers. A couple of challenge questions are then used to illustrate the distinction between performing actions and returning a value from a function.
