Python请编写错题本代码

以下是一个简单的Python错题本代码示例：

import os

class Question:
    def __init__(self, question, answer):
        self.question = question
        self.answer = answer
    
    def __str__(self):
        return f"{self.question}: {self.answer}"

class Quiz:
    def __init__(self, name):
        self.name = name
        self.questions = []
    
    def add_question(self, question, answer):
        self.questions.append(Question(question, answer))
    
    def remove_question(self, index):
        del self.questions[index]
    
    def list_questions(self):
        for i, question in enumerate(self.questions):
            print(f"{i+1}. {question}")
    
    def save_quiz(self):
        with open(f"{self.name}.txt", "w") as f:
            for question in self.questions:
                f.write(f"{question.question}|{question.answer}\n")
    
    def load_quiz(self):
        if os.path.exists(f"{self.name}.txt"):
            with open(f"{self.name}.txt", "r") as f:
                for line in f:
                    question, answer = line.strip().split("|")
                    self.add_question(question, answer)
            print(f"{self.name} quiz loaded.")
        else:
            print(f"{self.name} quiz does not exist.")
    
    def take_quiz(self):
        score = 0
        total = len(self.questions)
        for question in self.questions:
            user_answer = input(f"{question.question}: ")
            if user_answer == question.answer:
                score += 1
        print(f"Your score is {score}/{total}")
    
    def clear_quiz(self):
        self.questions = []
        if os.path.exists(f"{self.name}.txt"):
            os.remove(f"{self.name}.txt")
            print(f"{self.name} quiz deleted.")
        else:
            print(f"{self.name} quiz does not exist.")

这个代码实现了一个`Question`类和一个`Quiz`类，可以用来创建错题本。你可以通过以下方式来使用这个代码：

# 创建一个名为"python"的Quiz
python_quiz = Quiz("python")

# 添加问题和答案
python_quiz.add_question("What is the output of print(2+3*4)?", "14")
python_quiz.add_question("What is the keyword used for creating a function?", "def")
python_quiz.add_question("What is the output of print('hello'[::-1])?", "olleh")

# 列出所有问题和答案
python_quiz.list_questions()

# 保存Quiz
python_quiz.save_quiz()

# 加载Quiz
python_quiz.load_quiz()

# 进行Quiz
python_quiz.take_quiz()

# 清空Quiz
python_quiz.clear_quiz()

这个代码示例可以让你创建一个错题本，添加问题和答案，列出所有问题和答案，保存Quiz，加载Quiz，进行Quiz和清空Quiz。但是，请注意这个代码示例仅仅是一个简单的实现，如果你需要更复杂的功能，你需要根据自己的需要进行修改和扩展。
