First, if there's a better way to get the code in here than copy and paste, please let me know. Checking all the indents in python is a bit of a pain.
Second, please rip up this code! I'm trying to learn Python on my own and need all the feedback I can get. Please comment on everything: best practices, conventions...etc. Any and all comments welcome.
Thanks.
