Python 循环选择题

我正在做一个测验，帮助我学习a+认证，并帮助我学习Python。我“我试着做的是循环选择题，同时保持代码整洁，不重复我自己。我已经安排了几个问题，但我想听听关于清理的建议。我浏览了所有的互联网站，发现缺少关于这件事的信息。我希望能够循环通过问题，而不必调用底部的每个问题方法。谢谢你的帮助。这是我的密码：

answer = 0
correct = ""


def getAnswer():

    print "\n"
    prompt = ">"
    rawAnswer = raw_input(prompt)
    userAnswer = rawAnswer.upper()

    if userAnswer == correct:
        print "That is correct!!! \n\n"
        print "***************************************************************\n"
        global answer
        answer += 1
    else:
        print "That was wrong"

您应该使用列表或字典，而不是reach问题的函数。考虑以下事项：

questions = [ {prompt, [list of choices], correct answer index}, ... ]

例如：

questions = [ {'prompt':"What is 2 + 2?", 'choices': [3, 4, 5], 'answer_index': 1},
              {'prompt':"What is 2 + 3?", 'choices': [3, 4, 5, 6, 7], 'answer_index': 2} ]

然后，你可以像这样仔细检查它们：

for q in questions:
    print(q['prompt'])
    for i, c in enumerate(q['choices']):
        print(chr(97 + i) + ':', c)
    response = input("enter your answer:\n>>> ")
    print('The correct answer is:', chr(97 + q['answer_index']), '\n\n\n')

当我运行它（并输入答案）时，我得到：

就评分系统和if函数而言，这是否也适用于检查给定答案是否正确？您需要做的就是询问他们的答案，存储它，并将其与正确答案进行比较。如果分数对你很重要，你可以考虑存储答案索引，而不是答案，然后用索引打印出选择。这样做会使检查答案变得微不足道。感谢您的快速回复。我还希望能够键入a、b、c或d作为答案，而不是字符串。我已经找了一段时间了，但是我找不到如何正确地将答案设置为变量而不是字典中的字符串。我编辑了答案以添加字母索引。如果需要大写字母，请将97改为65。然后，如果您需要跟踪分数，只需添加一个新变量，并将正确答案与输入答案进行比较。
