Threading 多线程

Threading是Python自带的模块，无需安装。

args传递的必须是“元组”，所以单元素时，必须写成(x,)形式；

#!/usr/bin/env python
# coding: utf-8

import time
import threading

def task1(who):
    while True:
        print "hello " + str(who)
        time.sleep(1)

def task2():
    while True:
        print "What's up, man?"
        time.sleep(2)

t1 = threading.Thread(target=task1, args=('Qige',))
t2 = threading.Thread(target=task2)
t1.start()
t2.start()

#!/usr/bin/env python

from time import sleep
form threading import Thread

def task1(who):
    while True:
        print "hello %s" % (str(who))
        sleep(1)

def task2():
    while True:
        print "what's up, man?"
        sleep(2)

t1 = Thread(target = task1, args = ('Qige',))
t1.start()

t2 = Thread(target = task2)
t2.start()
