Is there a simple way to exit a while loop on keystroke?

You might want to look at http://docs.python.org/lib/module-curses.html

Another solution is to ask the user to hit CTRL-C
from time import sleep

try:
    while 1:
        print "BEEP"
        sleep(1)
except KeyboardInterrupt:
    print "BYE BYE"

HTH,
