写函数接受参数，判断并运行文件

import os
def func(path):
    if os.path.isfile(path):
        if path.endswith(".py"):
            os.system("python %s" % path)
    elif os.path.isdir(path):
        list_num = os.listdir(path)
        for name in list_num:
            list_next = os.path.join(path, name)
            func(list_next)
    return "Game over"
print(func(r'G:\salar\day6'))
