Tkinter Label（）计数器变量

Question

我目前正在做一个游戏，金特圭岩，布，剪刀游戏。我希望能够计算并存储用户、计算机和领带的胜算。我已经能够设置一个IntVar（）textvariable来与标签相关联，并且每当用户获胜时，我都会对其进行计数。但唯一的问题是，它只计算一个，例如（用户绘制“岩石”和计算机绘制“剪刀”[我们知道用户获胜，]但下次用户绘制石头，计算机绘制剪刀时，计数会降到0）。它只向上计数一次并重置，不转到下一个整数（因此它从0变为1，然后返回到0，而不是2）。有人能帮我做一个成功的计数器变量来计算胜负和平局。在

每次运行carryGame时都要初始化计数器变量。将它们提取到更高级别的作用域，以便只初始化一次：

下面是正在执行的代码的图像： （正确计数）

但一旦执行不同的命令（按下diff.按钮），计数就会变为0。

但如果用户再次获胜，则计数重新出现。

那么，我如何将号码一直显示在屏幕上？？在
