Python 添加多项选择分数

我需要在多项选择题测验中把分数加起来

这是我的代码：

找出范围、中位数、模式和平均值：
>>>232、4343、434、232.4、43、5453、434、232、645、23.3、53453.3、434我对您的代码进行了一些实验，问题似乎出在其他地方。出于某种原因，脚本总是在下一次比较if的错误答案。其他时候，在重新启动脚本而不清除旧变量后，它总是认为答案是正确的更正

我认为，如果您稍微清理一下代码，这个问题可能会消失。我建议您将代码作为类重写，这是Tkinter脚本的常见方法。对您来说，主要优势是：


它更具可读性（更易于调试）
不再使用全局变量，而是将变量作为类的一部分引用（self.variable）
当程序退出时（目前似乎做得不太好），您可以用del MyClass之类的东西来完成，以消除可变的混乱。这种混乱可能就是这个bug行为不时变化的原因
