通信多进程

import time
#进程实现多任务的步骤：

1.导入模块：

from multiprocessing import Process


def sing():
    for i in range(3):
        time.sleep(1)
        print('唱第%d首歌儿'%i)

def dance():
    for i in range(3):
        time.sleep(1)
        print('跳第%d段舞蹈'%i)


if __name__ == '__main__':

    #2.创建进程
    p = Process(target=sing)

    #3.启动
    p.start()

    dance()
