Running a timer for function which will be called later (python) -

def child_thread(i):     global lock      while true:         try:             lock.acquire()                 f1()                 f2()                 f3()         :             lock.release()  thread1 = threading.thread(target=child_thread, args=(0,)) thread1.start() 

here need timer f2 function called.were thread should wait time. dont want use sleep.

the function call after 30.0 seconds

from threading import timer  def hello():     print "hello, world"  t = timer(30.0, hello) t.start()
