1.单进程

import time
def dance():for i in range(3):print("跳舞")time.sleep(6)
def sing():for i in range(3):print("唱歌")time.sleep(6)
if __name__ == '__main__':dance()sing()

2.多进程

import  multiprocessing
import time
def dance():for i in range(3):print("跳舞")time.sleep(6)
def sing():for i in range(3):print("唱歌")time.sleep(6)
if __name__ == '__main__':dance_process=multiprocessing.Process(target=dance)sing_process=multiprocessing.Process(target=sing)dance_process.start()sing_process.start()

步骤：

1.导入多进程的包import  multiprocessing

2.创建进程对象  dance_process进程对象名=multiprocessing.Process(target=函数名)

3.启动进程 dance_process.start()
