使用telebot开发Telegram quiz机器人如何在用户作答后展示正确答案

核心依赖Telegram Bot API推送的用户答题更新事件实现，步骤如下：

• 使用@bot.poll_answer_handler()装饰器注册答题事件处理函数
• 提前存储发送的测验ID与对应正确答案、所属会话的映射关系，收到答题事件后匹配映射发送提示

完整修改后代码 #

import telebot
bot = telebot.TeleBot("替换为你自己的API KEY")

# 存储测验映射：key为poll_id，value存储对应正确答案、会话id、正确选项id
poll_data = {}

print("Bot starting...")

@bot.message_handler(commands=['quiz'])
def quiz(message):
    q = 'What is the capital of Italy?'
    answers = ['Rome', 'London', 'Amsterdam']
    correct_option = 0
    # 发送测验并拿到返回的poll对象
    sent_poll = bot.send_poll(
        message.chat.id, 
        question=q, 
        options=answers, 
        correct_option_id=correct_option, 
        open_period=5
    )
    # 存入映射表
    poll_data[sent_poll.poll.id] = {
        "correct_answer": answers[correct_option],
        "chat_id": message.chat.id,
        "correct_option_id": correct_option
    }

@bot.poll_answer_handler()
def handle_quiz_answer(answer):
    poll_id = answer.poll_id
    # 匹配当前回答对应的测验
    if poll_id not in poll_data:
        return
    quiz_info = poll_data[poll_id]
    user_selected = answer.option_ids[0]
    # 生成提示文案
    if user_selected == quiz_info["correct_option_id"]:
        tip = "🎉 回答正确！"
    else:
        tip = "❌ 回答错误"
    # 发送正确答案提示
    bot.send_message(
        quiz_info["chat_id"],
        f"{tip}\n正确答案是 *{quiz_info['correct_answer']}*",
        parse_mode="Markdown"
    )
    # 可选：私聊场景下单次回答后移除映射，避免重复推送
    # del poll_data[poll_id]

bot.polling()

注意事项 #

• 上述代码默认适配私聊场景，如果需要在群组中使用，可扩展poll_data的存储结构，支持多用户同一测验的答题统计
• 建议定期清理poll_data中已超过open_period时长的过期测验数据，避免内存占用过高
