7.3.2 - 并发多线程 开启的两种方式

一 threading模块介绍

multiprocess模块的完全模仿了threading模块的接口，二者在使用层面，有很大的相似性

二 开启线程的两种方式

方式一

from threading import Thread
import time
import random

def running(name):
    print("%s is running" % name)
    time.sleep(random.randint(1,3))
    print("%s running end" % name)

if __name__ == "__main__":
    t1 = Thread(target=running,args=("camz",))
    t1.start()

camz is running
camz running end

运行结果

 

方式二

from threading import Thread
import time
import random

class Say(Thread):
    def __init__(self, name):
        super().__init__()
        self.name = name

    def run(self):
        print("%s is running" % self.name)
        time.sleep(random.randint(1,3))
        print("%s running end" % self.name)

if __name__ == "__main__":
    t1 = Say("cmz")
    t1.start()
    print('主线程')

cmz is running
主线程
cmz running end

运行结果
