Question

我在Tkinter / Python中创建了一个十问题多项选择测验。基本上在父窗口中有13个按钮 - 帮助按钮，用户详细信息，问题1-10和“结束”按钮。每个按钮打开一个带有问题的新窗口，选项作为检查按钮和单选按钮，以及一个“输入”按钮，该按钮链接到一段代码，该代码将计算正确的答案，如果条件为真，则为分数加1。一旦用户选择了答案并按下“Enter”，该按钮将被禁用。然而，一旦用户退出该窗口，他们就能够回答相同的问题，这显然会导致多个点被添加到全局变量得分中。一旦用户回答了问题，如何禁用问题按钮/窗口？如果所有问题都得到解答，我如何才能激活“显示分数”按钮？

我已经使用了一个类为每个按钮定义了每个按钮和各个类，所以我不确定这是否会导致问题（我是面向对象的新手）。感谢

我知道压言不正确，我想为此网站格式化

如果它之后会创建一个新窗口，那么你就可以销毁它。

window.destroy()

“窗口”会根据您所说的tkinter而改变。 TK

window = tkinter. TK

无论在=之前是什么，取而代之的是“窗口”。希望有所帮助：）

如何禁用窗口？
