Python Functions

Mathematical functions can be reprsented as Python functions. However, there is a panoply of Python functions that are not mathematical functions. However, careful crafting of programs can cause many of your functions to be mathematical functions. This is desirable; understanding their actions and debugging with them is much simpler than with their messy brethern.

Let's begin with some examples.
