By the way, here is another way to do it. This way it will repeat, the
other one executed once. Of course, if it executed once, you can make
it do it again, but there is some trickery involved. Here is a way to
do it using threads.
Hope it helps,

from threading import Thread
from time import sleep
class Repeater(Thread):
def __init__(self,interval,fun,*args,**kw):
Thread.__init__(self)
self.interval=interval
self.fun=fun
self.args=args
self.kw=kw
self.keep_going=True
def run(self):
while(self.keep_going):
sleep(self.interval)
self.fun(*self.args,**self.kw)
def stop_repeating(self):
self.keep_going=False
def eat(*a):
print "eating: " , ','.join([stuff for stuff in a])
r=Repeater(1.0, eat, 'eggs','spam','kelp')
r.start()
sleep(6.0)
r.stop_repeating()
