Python Tkinter：继承语法或引用错误？
Python Tkinter: Inheritance Syntax or Reference mistake?
我是 python 的初学者，我正在尝试创建一个类似记分牌的 GUI。我做了一个事件，根据组合框选择通过按钮修改我的统计数据。小部件代码后有 4 个非常小的函数，第一个按预期工作，其他 3 个类似但它们只影响最后 3 个标签而不是组合框选择标签。我在那里想念什么？

对于单选按钮，您应该使用 class 属性（在我的代码中为 RBval）作为变量来控制所选值。您不需要将所有单选按钮存储在一个变量中。
然后，在您的赢、输、平局函数中，您无需输入所选单选按钮的数字。您刚刚读取了 RBval 的值。在您的代码中， i 始终等于 9 因为它是 i 在您的 forloop 中的最后一个值。
代码中可能还有很多遗留问题，但这是您的代码的工作版本：
