python学习笔记(53) 面向对象开启多线程

进程与进程之间数据是隔离的

from multiprocessing import Process
import os
class MyProcess(Process):
    def __init__(self,args1,args2):
        super().__init__()
        self.args1 = args1
        self.args2 = args2

    def run(self):
        print(os.getpid())
        print(self.pid)
        print(self.name)
        print(self.args1)
        print(self.args2)


if __name__ == '__main__':　　# windows系统多进程必须写在这条下面
    print('主：',os.getpid())
    p1 = MyProcess(args1=1,args2=2)
    p1.start()  # 自动触发run方法
    p2 = MyProcess(args1=3,args2=4)
    p2.start()
