Like this?

#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
import threading

def hello():
    print "hello, world"

t = threading.Timer(30.0, hello)
t.start() # after 30 seconds, "hello, world" will be printed
#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Timers start a new thread of execution.
