python3中线程中event的小栗子

import threading, time

class Boss(threading.Thread):    def run(self):        print("boss:今晚大家都要加班到22：00")        print(event.isSet())        event.set()        time.sleep(5)        print("BOSS:<22:00>可以下班了")        print(event.isSet())        event.set()

class Worker(threading.Thread):    def run(self):        event.wait()        print("worker:哎，命苦呀")        time.sleep(1)        event.clear()        event.wait()        print("worker: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()
