python选择题代码设计

以下是一个简单的 Python 选择题代码设计：

# 问题类
class Question:
    def __init__(self, text, choices, correct_answer):
        self.text = text
        self.choices = choices
        self.correct_answer = correct_answer

    def check_answer(self, answer):
        return answer.lower() == self.correct_answer.lower()

# 测验类
class Quiz:
    def __init__(self, questions):
        self.questions = questions
        self.score = 0
        self.current_question_index = 0

    def get_question(self):
        return self.questions[self.current_question_index]

    def display_question(self):
        question = self.get_question()
        print(question.text)
        for choice in question.choices:
            print("- " + choice)

    def next_question(self):
        self.current_question_index += 1

    def check_answer(self, answer):
        question = self.get_question()
        if question.check_answer(answer):
            self.score += 1
            print("Correct!")
        else:
            print("Incorrect!")
        self.next_question()

    def complete(self):
        print("Your score is", self.score, "out of", len(self.questions))

# 创建问题
q1 = Question("What is the capital of France?", ["London", "Paris", "Madrid", "Berlin"], "Paris")
q2 = Question("What is the largest country in the world?", ["Russia", "Canada", "China", "USA"], "Russia")
q3 = Question("What is the currency of Japan?", ["Yen", "Dollar", "Euro", "Pound"], "Yen")

# 创建测验
quiz = Quiz([q1, q2, q3])

# 显示问题并获取答案
while quiz.current_question_index < len(quiz.questions):
    quiz.display_question()
    answer = input("Enter your answer: ")
    quiz.check_answer(answer)

# 完成测验并显示得分
quiz.complete()

此代码实现了一个简单的选择题测验，包括问题类和测验类。问题类包含问题文本、选项和正确答案，测验类包含问题列表、得分和当前问题索引。测验类还包含显示问题、获取答案、检查答案和完成测验的方法。最后，通过循环显示每个问题，获取用户输入的答案，并检查答案是否正确。在完成所有问题后，测验类显示用户的得分。
