Python 考试系统代码

Python考试系统代码是一个用Python编写的程序，用于实现在线考试功能。它可以提供题目的展示、答题、自动评分等功能。以下是一个简单的Python考试系统代码示例：

class Question:
    def __init__(self, question, choices, answer):
        self.question = question
        self.choices = choices
        self.answer = answer

    def display_question(self):
        print(self.question)
        for i, choice in enumerate(self.choices):
            print(f"{i+1}. {choice}")

    def check_answer(self, user_answer):
        return user_answer == self.answer


class Exam:
    def __init__(self, questions):
        self.questions = questions
        self.score = 0

    def take_exam(self):
        for question in self.questions:
            question.display_question()
            user_answer = input("Your answer: ")
            if question.check_answer(user_answer):
                self.score += 1

    def get_result(self):
        print(f"Your score: {self.score}/{len(self.questions)}")


# 创建题目
question1 = Question("What is the capital of France?", ["A. Paris", "B. London", "C. Rome"], "A")
question2 = Question("What is the largest planet in our solar system?", ["A. Jupiter", "B. Earth", "C. Mars"], "A")
question3 = Question("What is the symbol for hydrogen?", ["A. H", "B. O", "C. He"], "A")

# 创建考试
exam = Exam([question1, question2, question3])

# 开始考试
exam.take_exam()

# 获取成绩
exam.get_result()
