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：
代码如下:
I am Thread-1,I will sleep ...
I am Thread-2,I will sleep ...
I am Thread-3,I will sleep ...
main thread sleep 3 seconds...
I am Thread-1, I awake...I am Thread-2, I awake...
I am Thread-3, I awake...
