Python 多进程_创建

1. 进程的创建方式1

from multiprocessing import Process
import time


def func(thread_name):
    print(thread_name)
    time.sleep(2)


if __name__ == '__main__':
    p =  Process(target=func, args=('process_1',))
    p2 = Process(target=func, args=('process_2',))

    p.start()
    p2.start()

 

2. 进程的创建方式2

from multiprocessing import Process
import time
class MyProcess(Process):

    def __init__(self,thread_name):
        super(MyProcess,self).__init__()
        self.thread_name=thread_name

    def run(self):
        print(self.thread_name)
        time.sleep(2)

if __name__ == '__main__':
    p = MyProcess('process_1')
    p2 =MyProcess('process_2')

    p.start()
    p2.start()
