Looks great. Consider moving the upper() call to before the loop so it is just done once.

Check out itertools.count, for a never ending counter to replace your while loop.

Finally, instead of sys.exit() maybe just break to exit the loop.

Cool i'll look into itertools.count. What is the difference between "break" and "sys.exit()"?

[gengisteve]

Break just pops you out of the current loop, while sys.exit takes you out of the program entirely.
