Hi Dick,

You only need one kbhit to tell you if any key has been hit at all.
Then you can use getch to fetch that key and store it in a variable.
Then the code above turns into:

while True:
   if kbhit(): key = getch()
   if key == ' ': break
   elif key == 'h': print 'hello'
   elif key == 'q': answer = 'quit'

Does that make sense?
