在一个进程中定义多个线程

import threading
from time import ctime,sleep
import time

def music(name):
    print(‘listening to {name}.{time}‘.format(name=name,time=ctime()))
    sleep(3)
    print(‘end {time}‘.format(time=ctime()))

def blog(title):
    print(‘recording the {title}.{time}‘.format(title=title,time=ctime()))
    sleep(5)
    print(‘end {time}‘.format(time=ctime()))

threads =[]
t1 =threading.Thread(target=music,args=(‘like‘,))
t2 =threading.Thread(target=blog,args=(‘beijing‘,))

threads.append(t1)
threads.append(t2)
if __name__ == ‘__main__‘:

    # t1.setDaemon(True) #注:一定要在start之前设置.它说明在主线程是否结束不考虑
          #  t1线程是否运行结束,故主线程是否结束于t2线程有关
    t2.setDaemon(True) #运行的结果与t1.setDaemon(True)的结果不同的然因是两个
     #  线程运行结束的时间不同
    for i in threads:  #运行t1和t2线程
        i.start()
    
    #t2.join()
    print(‘all over %s‘ % ctime())
