How do I check for a keypress without blocking?
Use the msvcrt module. This is a standard Windows-specific extension module. It defines a function msvcrt.kbhit which checks whether a keyboard hit is present, and msvcrt.getch which gets one character without echoing it.
import msvcrt while 1: c = msvcrt.getch() print "Got character", repr(c) if c == "q": break # quit
