You could make it even more general purpose buy putting the guts of it in a function called say, doAfter() def doAfter(t,f): ''' t is the time required and f is a function to be executed after t expires.''' Thus in your current case you would call doAfter( t, lambda : winsound.beep(500) )

Which is I believe what the Timer object in the threading module lets you do:

import threading, sys t = threading.Timer(10, sys.stdout.write, ['Done']) t.start() ...(waits for 10 secs)... Done

Documentation for the threading.Timer object can be found here: http://docs.python.org/lib/timer-objects.html

In order to pause one, I think you would need to send the thread a signal, but that sort of magic is beyond the skill of this python hack ;-) Maybe I'll play around with it and see if I can figure it out.
