I called it a matrix mostly because this is how I am visualizing it. They
are full of numbers but only as representatives of students and schools. It
looks like pprint will work after I read the instructions. At least I know
where to look now. In the end I need to figure out how to save the data a
csv formated for excel but that is for later I was just trying to make
it easier to debug my code.
