python中实现多线程的几种方式

python实现多线程的方式大概有

  1、threading

  2、_thread

#!/usr/bin/python
#!coding:utf-8
import threading


def action(msg):
    print '这个进程是通过 {0} 方式实现的'.format(msg)

class ActionThread(threading.Thread):
    def __init__(self,msg):
        threading.Thread.__init__(self)
        self.msg=msg
    def run(self):
        action(self.msg)

if __name__=="__main__":
    #多线程实现方法一、通过派生类
    at=ActionThread('threading.Thread的派生类')
    at.start()
    #多线程实例方法二、threading.Thread类
    t=threading.Thread(target=action,args=('threading.Thread类',))
    t.start()
    #通过_thread.start_new_thread 方法 _thread 是一个python自带的模块不过2.6.6好像不支持
    #_thread.start_new_thread(action,('通过_thread.start_new_thread方法',))

    at.join()
    t.join()
