'''进程在python中的实现
Process 类 在模块multiprocessing

import time
from multiprocessing import Process

def study():
    for i in range(5):
        print(i)

def listen():
    music = ["111","2222","333"]
    for i in music:
        print("music",i)
        time.sleep(0.2)
        #不加sleep的话，结果是顺序的，因为一个进程需要处理的时间太短

def wechat(name):
    for i in range(5):
        print("talk with {} about{}".format(name,i))
        time.sleep(0.2)


#创建多个进程
if __name__ == '__main__':
    #创建了多个进程对象
    p1 = Process(target=study)
    p2 = Process(target=listen)
    p3 = Process(target=wechat,args=('小芳',))


    #启动进程
    p1.start()
    p2.start()
    p3.start()
