python中使用随机函数和列表的多项选择测验

Question

我正在尝试使用 python 进行多项选择测验。起初它看起来很简单，但现在我很想弄清楚如何做某些事情。

我正在使用两个列表；一个用于问题，一个用于答案。我想这样做，以便从问题列表中选择一个随机问题，以及从答案列表中选择 2 个随机项目（错误答案），最后是正确答案（与随机选择的问题具有相同的索引）。 我已经选择了一个随机问题和两个随机错误答案

• 我的第一个问题是让程序显示正确答案。
• 第二个问题是如何检查用户输入的答案是否正确。

如果对我的代码提供任何反馈，我将不胜感激。我对此很陌生，所以请放轻松一点！ 我希望我的东西是可读的（抱歉有点长）

提前感谢

    def begin(): # would you like to begin? yes/no... leaves if no
        wanna_begin = input("Would you like to begin?: ").lower()
        if wanna_begin == ("yes"):
            print ("Ok let's go!\n")
            get_username()#gets the user name
        elif wanna_begin != ("no") and wanna_begin != ("yes"):
            print ("I don't understand, please enter yes or no:")
            return begin()

Answer 1

您可以使用另一个列表（例如correct_answer 等）来记录每个问题的正确答案。然后不要使用a1 = answers.pop(random_item) 选择错误的答案，而是使用

while True:
    if answer[random.randint(0, len(answers)-1)] != correct_answer[question]:
        break
a1 = answers.pop(id)

避免选择正确答案作为错误答案。

编辑

由于你的正确答案已经在answers中，所以选择错误答案时不要弹出项目，否则会破坏索引。

你可以像这样选择两个错误答案和一个正确答案。

correct = question_index

while True:
    wrong1 = random.randint(0, len(answers)-1)
    if wrong1 != correct:
        break

while True:
    wrong2 = random.randint(0, len(answers)-1)
    if wrong1 != wrong2 and wrong1 != correct:
        break

Answer 2

您可以使用字典以更简单的方式构建数据。每个项目都是一对键和一个值，更多信息请参阅this。 例如，您的数据将如下所示（每个问题都与一个答案相关联）：

data = {'question1': 'answer1', 'question2': 'answer2'}

然后我们可以在随机选择一个问题后循环遍历这个字典来打印答案。这里有一些 sudo 代码寻求帮助：

# Choose a random question

# Print all the answers in the dictionary
for key, value in data.iteritems(): #its data.items() in Python 3.x
     print value

# If the choice matches the answer
pop the question from the dictionary and do whatever you want to do

# Else, ask again
