Python Tkinter：继承语法或引用错误？

Question

我是 python 的初学者，我正在尝试创建一个类似于记分牌的 GUI。我做了一个事件，根据 Combobox 选择通过按钮修改我的统计信息。在小部件的代码之后有 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 Combobox 选择标签。我在那里想念什么？

对于您的单选按钮，您应该使用类属性（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、平功能中，您不需要输入所选单选按钮的数量。您只需读取 RBval 的值。在您的代码中，i 始终等于 9，因为它是您 forloop 中 i 的最后一个值。

代码中可能还有很多遗留问题，但这里是您的代码的工作版本：

from Tkinter import *

class Application(Frame):
    def __init__(self, master):
        Frame.__init__(self, master, relief="sunken", border=1)

        self.grid()

    def create_widgets(self):
        for i in range(9):
            box = ttk.Combobox(self, state="readonly")

            box["values"] = ("team A", "team B", "team C", "team D", "team E", "team F", "team G", "team H", "team I")
            box.current(i)
            self.box_list.append(box)
            box.bind("<<ComboboxSelected>>")
        self.RBval = IntVar()
        for i in range(9):
