python threading（多线程）

Posted 2020-12-03 平常心u

join()：在子线程完成运行之前，这个子线程的父线程将一直被阻塞。

setDaemon(True)：守护线程。主线程结束不会等待这个子线程，直接结束。

 

import threading
from time import ctime,sleep
import time

def music(func):
    for i in range(2):
        print ("Begin listening to %s. %s" %(func,ctime()))
        sleep(2)
        print("end listening %s"%ctime())

def move(func):
    for i in range(2):
        print ("Begin watching at the %s! %s" %(func,ctime()))
        sleep(3)
        print(‘end watching %s‘%ctime())

threads = []
t1 = threading.Thread(target=music,args=(‘安静‘,))
threads.append(t1)
t2 = threading.Thread(target=move,args=(‘阿甘‘,))
threads.append(t2)

if __name__ == ‘__main__‘:

    for t in threads:
        # t.setDaemon(True)
        t.start()
    # t.join()
    t1.join()
    # t2.join()
    print ("all over %s" %ctime())
