一个简单的Python多线程

首先对一段普通的代码进行测试

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

import time

def RunThreading(n):
    print("Running %s Threading"%n)
    time.sleep(3)

RunThreading("First")
RunThreading("Second")

运行脚本

首先打印Running First Threading，然后间隔3秒打印Running Second Threading，最后间隔3秒结束

等待时间为6s

接下来测试多线程的脚本进行对比

# -*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

import threading
import time

def RunThreading(n):
    print("Running" ,n, "Threading")
    time.sleep(3)

t1 = threading.Thread(target=RunThreading, args=("First",))#即使只有一个参数也要加逗号
t2 = threading.Thread(target=RunThreading, args=("Second",))

t1.start()
t2.start()

运行脚本

同时打印出Running First Threading和Running Second Threading，脚本没有立即结束，而是间隔了三秒之后才结束

t1和t2是同时进行的，所以等待的时间只有3s

用类方法来调用多线程

#-*- coding:utf-8 -*-
__author__ = "MuT6 Sch01aR"

import threading

class MyThread(threading.Thread):
    def __init__(self,n):
        super(MyThread,self).__init__()
        self.n = n

    def run(self):  #必须是run
        print ("Running %s Threading"%self.n)

t1 = MyThread("First")
t2 = MyThread("Second")

t1.start()
t2.start()

运行结果
