threading 多线程处理工具

单线程

1.案例

from time import ctime,sleep
def music():
    for i in range(2):
        print "I was listening to music. %s" %ctime()
        sleep(1)
def move():
    for i in range(2):
        print "I was at the movies! %s" %ctime()
        sleep(5)
if __name__ == '__main__':
    music()
    move()
    print "all over %s" %ctime()

多线程

import threading
from time import ctime,sleep
def music(func):
    for i in range(2):
        print "I was listening to %s. %s" %(func,ctime())
        sleep(1)
def move(func):
    for i in range(2):
        print "I was at the %s! %s" %(func,ctime())
        sleep(5)
#多线程配置
t1 = threading.Thread(target=music,args=(u'GD',))
t2 = threading.Thread(target=move,args=(u'阿凡达',))
if __name__ == '__main__':
    #所有多线程一起启动
    #设置非守护进程，父进程会等待所有子进程执行完毕，父进程才会退出
    t1.setDaemon(False)
    t1.start()
    #设置守护进程 (子线程启动后，父进程不等待子进程继续执行，当父进程执行完毕，子进程也一起退出)
    t2.setDaemon(True)
    t2.start();
    print "all over %s" %ctime()
    #当前运行中的Thread对象列表
    for item in threading.enumerate():
        print item
