如何使用按钮在Tkinter中创建测验

Question

我正在尝试进行测验，以问另一个问题，并在按下按钮后加载与该问题相关的答案。它加载第一个问题，一个按钮具有正确的答案，而三个按钮具有错误的答案（本来应该是多重选择，所以应该这样做），但是当按下一个按钮时，新的问题不会加载。它说我按下按钮时未定义ID。

那么我如何循环它，以便出现新的ID，从而加载新的问题。多项选择有效，只是循环而已。

class Page2(Page):
    def __init__(self, *args, **kwargs):
        Page.__init__(self, *args, **kwargs)
        self.Question_Counter = 0
        self.Correct_Answers = 0
        self.getQuest
        self.AnswerQuestion

        self.ID = random.randint(1,100)
        QuestionSet.add(self.ID)
        self.QuestionAsked = self.getQuest(self.ID)
        QuestionSet.add(self.QuestionAsked)
        Answers = [self.GetAnswer(self.ID)]
        self.CorrectAnswer = self.GetAnswer(self.ID)
        for ID in range(3):
            new_id = random.randint(1,100)
            while new_id in Answers:
                new_id = random.randint(1,100)
            Answers.append(self.GetAnswer(new_id))
        self.OriginalAnswers = Answers[:]

        b4 = tk.Button(self, text = Answers[0], command = self.AnswerQuestion)
        b4.grid(row = 4, column = 3, pady = 10)
        del Answers[0]

            return (c.execute("SELECT Question FROM Questions WHERE QuestionID = {}".format(ID)).fetchone()[0])
            self.Loading(self)

    def AnswerQuestion(self):
        if self.CorrectAnswer == self.GetAnswer(self.ID):
            self.Correct_Answers += 1
        self.Question_Counter += 1
        self.getQuest(self,ID)
