Question

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,"%")

Answer 1

import random

counter = 0
score = 0
incorrect = 0

questions = ["10*2","4-2","6+12","6*4"]
answers=["20","2","18","24"]

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")
        elif idxq == idxa and ans != answer:
            print("Incorrect")

Answer 2

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])

当然你应该建立一些机制来阻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]

Answer 3

您的代码的问题是使用random.shuffle()函数。

它以随机的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。

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。

可能有更优雅的解决方案，这只是一个快速的答案。
