Question

所以我正在做一个测验作为学校的项目，它从数据库浏览器（SQlite）中选择已经提出的问题并使用tkinter显示它们。当我运行测验时，会显示所有图形，然后当我输入我的答案并提交时，会出现此错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python34\lib\tkinter\__init__.py", line 1533, in __call__
    return self.func(*args)
  File "S:\year 13\computing project\project\MAIN PROJECT CODE.py", line 126, in confirmAnswer
    if self.Qn < self.recordNum:

TypeError: unorderable types: int() < Label()

这只是代码片段，所以如果整个代码，请说谢谢你的帮助！

def quiz(self):
            self.newf.pack_forget()
            self.head['text'] = 'Welcome to the psychology revision quiz'
            self.quizf.pack()

            self.quizScore = 0
            self.correctAnswer = ''  # <-- create it at start (and use better name)
            self.Qn = 1
            self.update_question()# <-- get new question
            self.update_question_number()
        def update_question_number(self):
            # Get question's number

            query = "SELECT MAX(qnumber) FROM questions"
            c.execute(query)
            row = c.fetchone()

            self.recordNum['text'] = row[0]

        def update_question(self):
            # Get new question

            query = "SELECT * FROM questions WHERE qnumber=?"
            c.execute(query, (self.Qn,))
            row = c.fetchone()

            self.question['text'] = row[1]

            self.answer1['text'] = row[2]
            self.answer2['text'] = row[3]
            self.answer3['text'] = row[4]
            self.answer4['text'] = row[5]

            self.correctAnswer = row[6]    

        def confirmAnswer(self):
            self.rightOrWrong = self.enterAnswer
            if self.enterAnswer == self.correctAnswer:
                self.rightOrWrong['text'] = "Correct"
                self.quizScore += 1
                self.update_question()
            else:
                self.rightOrWrong['text'] = "Incorrect"

            if self.Qn < self.recordNum:
                self.Qn += 1           # <-- get new question
                self.update_question() # <-- get new question

            else:
                self.rightOrWrong['text'] = "Quiz Complete! Your score was: {}".format(self.quizScore)

Answer 1

尝试替换

if self.Qn < self.recordNum:

与

if self.Qn < self.recordNum['text']:
