程序运行它的最后一部分的主要问题是显示错误的操作数类型，但这只发生在加法和乘法而不是减法时，每次程序要求添加乘法时都会引起混淆，我回答正确或不正确为+ =：int和NoneType显示以下消息不支持的操作数类型。

Answer 1

您没有正确缩进功能中的return score。目前，它仅在else部分返回分数：

if question2 == total_m:
    print("Correct!")
    score=score+1
else:
    print("Incorrect!")
    print(total_m)
    return score

因此，如果您打印正确，该函数将返回“nothing”，即NoneType 改为

if question2 == total_m:
    print("Correct!")
    score=score+1
else:
    print("Incorrect!")
    print(total_m)
return score

我的分数和功能不起作用
