我的基本测验软件中的列表有问题

Question

我是运行下面写的代码块：

class Question:
    
    def __init__(self,text,choices,answer):
        self.text = text
        self.choices = choices
        self.answer = answer
        
    def checkAnswer(self, answer):
        return self.answer == answer
 class Quiz:
    
    def __init__(self, questions):
        self.questions = questions
        self.score = 0
        self.questionsIndex = 0
        
    def getQuestion(self):
        return self.questions[self.questionsIndex]
    
    def displayQuestion(self):
        question = self.getQuestion()
        print(f"Question: {self.questionsIndex +1}: {question.text}")   
        for q in question.choices:
            print("-"+ q)
        answer = input("Your Answer:  ")
        self.guess(answer)
        self.loadQuestion()
        
    def guess(self, answer):
        question = self.getQuestion()
        if question.checkAnswer(answer):
            self.score += 1
        self.questionsIndex += 1
        self.displayQuestion()
        
    def loadQuestion(self):
        if len(self.questions) == self.questionsIndex:
            self.showScore()
        else:
            self.displayProgress()
            self.displayQuestion()
            
    def showScore(self):
        print("Score: ", self.score)
        
    def displayProgress(self):
        totalQuestion = len(self.questions)
        questionNumber = self.questionsIndex + 1
        if questionNumber > totalQuestion:
            print("Quiz Finished")
        else:
            print(f"*************************Question {questionNumber} of {totalQuestion}***********************************")
           

q1 = Question("Which programming language is the most profitable?["C#","Python","Java","HTML"],"Python")
q2 = Question("Which is the easiest programming language?", ["C#","Python","Java","HTML"],"Python")
q3 = Question("What is the most popular programming language?", ["C#","Python","Java","HTML"],"Python")
questions = [q1,q2,q3]
quiz = Quiz(questions)
quiz.loadQuestion()

我面临以下问题：

IndexError: list index out of range

你能告诉我这是什么原因吗？为什么列表有问题？我添加这个是因为 Whosebug 希望我添加更多细节：我试图在这个软件中使用基本 class 方法构建一个测验，但我运行遇到了问题。

Answer 1

在 displayQuestion 方法中调用 guess 方法。在 guess 方法中增加 questionsIndex 值，然后再次调用 displayQuestion 方法。

这个过程不断重复，直到 questionIndex 变为 out of range。看来您需要从 guess 方法中删除对 displayQuestion 方法的调用。
