Check out the sched (scheduler) module http://docs.python.org/lib/module-sched.html. Here is an example that shows how to implement a loop (modified from the documentation): (warning, this will run forever) [code] import sched, time s=sched.scheduler(time.time, time.sleep) def print_time(): s.enter(1,1, print_time, ()) print "From print_time", time.time() def print_some_times(): print time.time() s.enter(5, 1, print_time, ()) s.run() if __name__ == "__main__": print_some_times() [/code] -- http://mail.python.org/mailman/listinfo/python-list
