    while True:
        print("這是%s%s"%(str,os.getppid()))
        sleep(1.2)

等待進程

import os
def run(str):
    for i in range(10):
        print("這是%s%s"%(str,os.getppid()))
        sleep(1.2)

if __name__=="__main__":
    print("進程開始")
    p = Process(target=run, args=("子進程",))
    p.start()                                   #子進程開始
    p.join()                                    #等待子進程結束
    print("父進程結束")
