Tkinter测验中添加了不需要的按钮

Question

这里的代码是一个测验。此时，代码会创建一个包含问题和答案的窗口，当按下正确的答案（较大的按钮）时，它会创建另一个窗口，上面有一个“ok”按钮和一条消息“correct”。单击“确定”按钮后，问题窗口将刷新为另一个问题。当您再次单击正确答案时，窗口将再次显示“确定”按钮，但它将有两个按钮。这种情况会一直发生，每次代码循环时都会添加一个“ok”按钮。有什么办法可以解决吗？你知道吗

（我还被告知，有一种更简单的方法可以整体完成这项工作，我实际上首先生成问题和答案，然后将它们放入列表中，然后随机调用它们，这样我就可以确保问题不会重复。然后我可以有“正确”的信息出现在同一个窗口，并禁用按钮，使我不能点击另一个答案。信息将转到下一个有新答案的问题。这可能吗？如果是这样，那将是一个巨大的帮助）。你知道吗

谢谢你的帮助。你知道吗

Answer 1

首先，不要在一个应用程序中生成多个Tk对象。这就是顶级小部件的用途。现在，您只有两个选项来纠正错误。一种是在程序启动时生成一个顶级对象并显示/隐藏它，另一种是在每次需要显示时生成一个新的顶级对象，然后销毁它。为了简单起见，我将演示第二个-这里是您的函数编辑工作（希望如此）：

def well_done():
    welldone = Toplevel()
    text = Text(welldone)
    text.insert(INSERT, "WHATYOUTALKINGTOME")
    text.insert(END, "?!")
    text.pack()
    okbutton = Button(welldone, text="Ok", command=(lambda: welldone.destroy() or game_loop()))

    okbutton.pack()

lambda技巧有点脏，但是如果您不愿意为welldone使用全局引用，那么它是必要的。你知道吗

至于问题的第二部分，我将使用随机模块中的shuffle函数。将问答列表压缩为元组列表（python3的zip(questions, correctanswers, possibleanswer1s, possibleanswer2s, possibleanswer3s)或list(zip(...))大小写），然后对结果进行无序排列。反复阅读并填写问题和答案：

zipped=zip(questions, correctanswers, possibleanswer1s, possibleanswer2s, possibleanswer3s)
for q, ca, ica1, ica2, ica3 in random.shuffle(zipped):
    text.insert(INSERT, q)
    answer1button = Button(master, text=ca, width=20, command=correctans)
    answer2button = Button(master, text=ica1, command=wrong)
    answer3button = Button(master, text=ica2, command=wrong)
    answer4button = Button(master, text=ica3, command=wrong)
    question = question + 1

对于问题的第三部分，我将不提供任何代码，因为问题太松散了。您可以添加标签或文本小部件，并使用pack\u forget（）（如果使用grid，则使用grid\u forget（））将其“解包”。当然，你可以再正常打包。你知道吗
