print('几次')


if __name__ == '__main__':
    process2 = multiprocessing.Process(target=demo)

Description

After adding multiprocess code to main, it will run multiple times. For example, if I add a process to main, this code will run twice. May I ask why? Can you help me solve this problem?Thanks！
