python,用event方法实现线程间通信控制

import threading,time
class Boss(threading.Thread):
    def run(self):
        print("We must work today!")
        event.isSet() or event.set()
        time.sleep(5)
        print("You can go home right now!")
        event.isSet() or event.set()

class Worker(threading.Thread):
    def run(self):
        event.wait()
        print("Oh,my god!!!")
        time.sleep(1)
        event.clear()
        event.wait()
        print("Oh,yeah!!!")
if __name__ == "__main__":
    event = threading.Event()
    threads = []
    for i in range(5):
        threads.append(Worker())
    threads.append(Boss())
    for t in threads:
        t.start()
    for t in threads:
        t.join()

运行后显示:

We must work today!
Oh,my god!!!
Oh,my god!!!
Oh,my god!!!
Oh,my god!!!
Oh,my god!!!
You can go home right now!
Oh,yeah!!!
Oh,yeah!!!
