Thanks everyone for your help. I'm not opposed to using [key.lower() for key
in stage_map] at all, I was just curious to see if there were any cleaner
alternatives. It looks like that is what I'll be using. I'm not familiar
with how python works internally, but coming from C++ it seems like
"remaking" the map would be slow. However, speed is not my main concern in
my particular situation, I'm just curious to learn more about python.

Thanks again everyone.
