Not at all like Chris advised. But it also doesn't help you understand
programming. Two concepts you're going to have to get a lot more
comfortable with, in Python, or in some other language. One is loops,
and the other is functions.

This is one enormous top-level code, and when you needed to enclose it
in a loop, your answer is to start a new process! You also duplicate
quite a few lines, rather than making a function for them, and calling
it from two places.
