Python测验应用如何从列表15道题中选10道作答，答对进入下一阶段

1. 导入Python内置random模块，使用其中的sample方法从15道总题库中随机抽取10道不重复的题目
2. 调整测试运行函数的逻辑，在用户顺利答完10道题（无答错中断）时，触发下一阶段的入口
3. 修正原代码中少量语法和体验问题

修改后完整可运行代码 #

    def __init__(self,prompt,answer):
        self.prompt = prompt
        self.answer = answer

def run_test(questions):
    score = 0
    for question in questions:
        answer = input(question.prompt).strip() # 加strip去除用户输入的首尾空格避免误判
        if answer == question.answer:
            score += 1
            print("回答正确")
        else:
            print("回答错误")
            print (f"你的得分是 {score}/10")
            print("挑战失败，你未通过简易难度测试")
            break
    # 循环正常结束说明没有答错中断，10题全对
    else:
        print(f"恭喜你全部答对，得分 {score}/10")
        print("正在进入测验下一阶段...")
        # 这里写你下一阶段的调用逻辑即可

# 随机抽取10道题
selected_questions = random.sample(questions, 10)
run_test(selected_questions)

核心说明 #

• random.sample(源列表, 抽取数量) 会返回一个包含指定数量不重复元素的新列表，每次运行都会随机抽题，符合测验类应用的需求
• for循环附带的else分支只有在循环没有被break中断时才会执行，刚好用来判断用户是否全部答对
• 新增的strip()方法会自动去除用户输入前后的空格、换行符，避免因为输入时多打了空格导致被判错
