我正在尝试创建一个数学游戏，它从我的列表中随机选择一个问题并给出相应的答案 . 目前，我可以将问题随机化，然而，它从列表中按顺序给出答案，而不是对应于问题的答案 . 如何得到随机问题的答案是正确的 . 这是我的代码 .

import random

counter = 0
score = 0
incorrect = 0

name=input("What is your name?")
print("Hi",name,",welcome to your math quiz!")

questions = ["10*2","4-2","6+12","6*4","12-5","6+54","1*0","3-6","4+0","65-9"]
answers=["20","2","18","24",'7','60','0','-3','4','56']

idx_questions = list(enumerate(questions))
idx_answers = list(enumerate(answers))

random.shuffle(idx_questions)

for idxq, question in idx_questions:
    print(question)
    ans = input("What is the answer? ")
    for idxa, answer in idx_answers:
        if idxq == idxa and ans == answer:
            print("Correct")
            score=score+1
            print("Correct Answers=",score)
            print("Incorrect Answers=",incorrect)

        elif idxq == idxa and ans != answer:
            print("Incorrect", answers)
            incorrect=incorrect+1
            print("Correct Answers=",score)
            print("Incorrect Answers=",incorrect)

print("End of quiz")
print(name,"your score is",score,"out of 10")
print(score*10,"%")

    问题是你洗牌问题列表，而答案列表保持不变 . 所以现在答案和问题，有一个不同的位置，他们不匹配 . 相反，您应该只在该索引处生成随机索引和打印问题 .

    random_int = random.randint(0, len(questions)-1)
print(question[random_int])

    当然你应该 Build 一些机制来防止相同的答案弹出两次 . 一种方法是删除用过的问题 .

    del questions[random_int]
del answers[random_int]

    您的代码的问题是使用 random.shuffle() 函数 .

    它以随机方式对您的问题列表进行随机播放（基本上是围绕列表中的元素进行交换），因此您对应的特定索引答案将与问题列表不匹配 .

    这个答案应该更清楚：https://stackoverflow.com/a/976918/8750461

    相反，您可能希望使用 q = random.choice(questions) 来获取随机问题，然后使用 answers[questions.index(q)] 获取相应的答案 .

    可能有比这更优雅的解决方案，这只是一个快速的答案 .
