threading has a Timer:


    >>> def print_msg(msg):
    ...     print msg

    >>> t = threading.Timer(1, print_msg, ('Spam',))
    >>> t.start()
    >>> Spam

    >>> t = threading.Timer(3, print_msg, ('Spam',))
    >>> t.start(); t.join()  # waiting...

There's also the sched module, but only if you're not using threads:


    >>> s = sched.scheduler(time.time, time.sleep)

    >>> e = s.enter(3, 1, print_msg, ('Spam',))
    >>> s.run()

    >>> e = s.enterabs(time.time() + 5, 1, print_msg, ('Spam',))
    >>> s.run()
