python基于event实现线程间通信控制

这篇文章主要介绍了python基于event实现线程间通信控制,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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!!!
Oh,yeah!!!
Oh,yeah!!!
