python开启多线程

多线程

import threading
import time
def music():
	print("start to listen %s" % time.ctime())
	time.sleep(3)
 	print("stop to listen %s" % time.ctime())
def game():
	print("start to play game %s" % time.ctime())
	time.sleep(5)
	print("stop to play game %s" % time.ctime())
t1 = threading.Thread(target=music)  #  创建子线程对象t1
t1.start()  #  启动子线程t1
t2 = threading.Thread(target=game)  #  创建子线程对象t2
t2.start()  #  启动子线程t2
t2.join()  #  使得子进程t2完成才开始下一个进程
print()
print("ending......") # 主线程
