开启子进程的两种方式

# 方式一
# from multiprocessing import Process
# import time
# def task(name):
#     print(‘%s is runing‘%name)
#     time.sleep(3)
#     print(‘%s is down‘%name)
# if __name__ == ‘__main__‘:
#     p = Process(target = task, args = (‘子进程1‘,))
#     p.start()
#     print(‘主‘)
#方式二
from multiprocessing import Process
import time
class Myprocess(Process):
    def __init__(self, name):
        super().__init__()
        self.name = name

    def run(self):
        print(‘%s is runing‘%self.name)
        time.sleep(3)
        print(‘%s is down‘%self.name)
if __name__ == ‘__main__‘:
    #p = Myprocess(‘子进程‘)
    p2 = Myprocess(name = ‘子进程2‘)
    p2.start()
    print(‘主‘)
