Unable to run python file on Mac OSX

[cylonspy2]

I don't really do this sort of programming work, so sorry if I'm doing something wrong here,,,
I installed all the dependencies, made sure python was up to date, all that jazz.
But when I try to run the 'humblesteamkeysredeemer.py' file, it halts at the first line, saying there's no requests module to import.
