如何修改Python测验游戏代码，实现从字典取题并实时验证答案？

核心调整方向 #

将原本分离的题目列表和答案判断逻辑，整合为题目-答案字典，让数据结构更直观，同时简化答案校验的代码逻辑，避免冗余的多条件判断。

具体修改步骤 #

• 替换题目存储结构：把原来的questions列表改为字典，键是题目文本，值是对应的正确答案（统一用小写字符串）：

  quiz_questions = {
      "Banana is a vegetable": "false",
      "Two plus two equals to four": "true",
      "Mumbai is the capital of present India": "false",
      "Tiger is an example of bird": "false",
      "Punjab is a country": "false"
  }
  

• 修复用户输入处理bug：原代码中ans1.lower()没有重新赋值，导致输入大小写不生效，改为：

  ans1 = ans1.lower()
  

• 简化答案判断逻辑：不再通过索引匹配题目，直接从字典中获取当前题目的正确答案，对比用户输入：

  if ans1 == correct_answer:
      points += 1
      print("答对了！")
  else:
      print(f"答错了，正确答案是{correct_answer}")
  

• 避免重复抽题：原代码用choice可能重复抽取同一题目，改为先将字典转成列表并打乱，再依次遍历：

  question_list = list(quiz_questions.items())
  shuffle(question_list)
  for current_question, correct_answer in question_list:
  

完整优化代码 #

from random import shuffle

print("""Welcome to the quiz game 
Would you like to play?  """)
consent = input("-----> ").lower()

if consent == "no":
    print("The game ends")
    quit()
else:
    print("Be ready to play")
    print("Answer the questions with 'true' or 'false'")

points = 0
# 用字典存储题目和对应正确答案
quiz_questions = {
    "Banana is a vegetable": "false",
    "Two plus two equals to four": "true",
    "Mumbai is the capital of present India": "false",
    "Tiger is an example of bird": "false",
    "Punjab is a country": "false"
}

# 将题目转成列表并打乱顺序，避免重复出题
question_list = list(quiz_questions.items())
shuffle(question_list)

for current_question, correct_answer in question_list:
    print(f"\nQuestion: {current_question}")
    ans1 = input("(True/False)----> ").lower()
    
    if ans1 == correct_answer:
        points += 1
        print("✅ Correct!")
    else:
        print(f"❌ Wrong! The correct answer is: {correct_answer}")
    
    print(f"Current points: {points}")

print(f"\nGame over! Your final score is: {points}/{len(quiz_questions)}")
