你center_rect的参数只有4个，但你在gambia里调用center_rect却填了5个参数

你的报错肯定是：

Traceback (most recent call last):
    File "C:/Users/mis/Desktop/Python系统课/XXX.py", line 13, in <module>
        gambia(0, 0)
    File "C:/Users/mis/Desktop/Python系统课/XXX.py", line 11, in gambia
        center_rect(x, y, w, h / 7, 7)
TypeError: center_rect() takes 4 positional arguments but 5 were given
