from multiprocessing import Process
import time, os


# 定义task,开启进程就是执行任务
def task():
    # print('%s is running' % os.getpid())  # 33808 is running
    print('%s is running, parent id is <%s>' % (os.getpid(), os.getppid()))
    # parent id is <5384>,与进程print('主', os.getpid()) 相同
    time.sleep(3)
    print('%s is done' % os.getpid())  # 33808 is done


if __name__ == '__main__':
    p = Process(target=task,)
    p.start()
    # 主进程开始(下面print)
    print('主', os.getpid())  # 主 20096 (就是pycharm的id)
