import threading
import time

class MyThread(threading.Thread):
def __init__(self, signal):
threading.Thread.__init__(self)
self.singal = signal

def run(self):
print "I am %s,I will sleep ..."%self.name
self.singal.wait()
print "I am %s, I awake..." %self.name

if __name__ == "__main__":
singal = threading.Event()
for t in range(0, 3):
thread = MyThread(singal)
thread.start()

print "main thread sleep 3 seconds... "
time.sleep(3)

singal.set()

运行效果如下：
