# coding:utf-8 import os from multiprocessing import Process class MyProcess(Process): def __init__(self, nam): super().__init__() self.nam = nam # 因为父类里有name属性了,如果这里还是使用属性name,会覆盖父类name的值,我使用了nam def run(self): print("子进程开始.") print("子进程号os.getpid():", os.getpid()) print("子进程名字name:", self.name) print("子进程结束.") if __name__ == '__main__': p = MyProcess("lily") p.start() print("p.name:", p.name) print("p.pid:", p.pid)
执行结果: # p.name: MyProcess-1 # p.pid: 6388 # 子进程开始. # 子进程号os.getpid(): 6388 # 子进程名字name: MyProcess-1 # 子进程结束.
有没有发现,获取进程号的方法有两种:p.pid和os.getpid()
