用python写多线程

import threading                  #首先导入threading 模块，这是使用多线程的前提
from time import ctime,sleep

def music(func):
    for i in range(3):
        print "I was listening to" +func+ctime()
        sleep(2)
def movie(func):
    for i in range(2):
        print "I was at the %s! %s" %(func,ctime())
        sleep(5)
def eat_time(func):
    for i in range(5):
        print ‘l am eatting food %s. %s‘ %(func,ctime())
        sleep(1)

threads = []        
t1 = threading.Thread(target=music,args=(u‘爱情买卖‘,))
threads.append(t1)     #创建了threads数组，创建线程t1,使用threading.Thread()方法，在这个方法中调用music方法target=music，args方法对music进行传参。 把创建好的线程t1装到threads数组中。
t2 = threading.Thread(target=movie,args=(u‘阿凡达‘,))
threads.append(t2)
t3 = threading.Thread(target=eat_time,args=(u‘爆米花‘,))
threads.append(t3)

if __name__ == ‘__main__‘:
    for t in threads:
        t.setDaemon(True)    #setDaemon(True)将线程声明为守护线程，必须在start() 方法调用之前设置，如果不设置为守护线程程序会被无限挂起。子线程启动后，父线程也继续执行下去，当父线程执行完最后一条语句后，没有等待子线程，直接就退出了，同时子线程也一同结束。
        t.start()           #开始线程活动
print "夜深了我要睡觉了！！！！！！！！！！！！！！！！！！！！！！！！！！！！ %s" %ctime()  #此句代码为主线程
