Python工具/包，从文本fi的问题和答案选项生成测验

Question

我有一个文本文件，其中有30个选择题在下面的模式

1. 第一个问题在这里？你知道吗

   A.方案1

   B.方案2

   C.方案3

   D.选项4

以此类推到30岁

选项的数量是可变的；至少有两个选项，最多有六个选项。你知道吗

我想在html/php测验这样的界面上练习这些问题，它允许我选择选项并最终显示结果。你知道吗

我试着用python阅读这个文件，然后尝试将问题和答案存储在单独的列表中，但没有成功。 下面是我的代码：

#to prevent IndexError 
question = ['','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','']
answers = ['','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','','']
qOrA = "q"
mcq_file = "mcqs.txt"
mcq = open(mcq_file, "r")
data_list = mcq.readlines()

for i in range(len(data_list)):
    element = list(data_list[i])
    if element[0] == "A" and element[1] == ".":
        qOrA = "a"

    if qOrA == "q":
        question[i] = question[i]+ " " + data_list[i]

    elif qOrA == "a":
        answers[i] = answers[i]+ " " + data_list[i]

你知道吗mcq.readlines文件（）问题3的结果如下 注意：实际上有多个换行符，因此文件结构不正确。你知道吗

Answer 1

希望这是你想要的。有些小错误是因为mcqs.txt文件不可预测的不一致。例如，在问题5中，答案出现了错误。当我们选择容纳问题26的小写答案选择时，我们就把一个邪恶换成另一个邪恶，这就是为什么问题3的答案选择看起来很奇怪（“网站”和“主板”。以“e”和“d”结尾）。同样，问题25写在2\n 5。这就是为什么输出中偶尔会有单独的单词串联在一起。我很想知道原始文件是什么格式的，为什么它会被弄坏？这些是错别字还是你从PDF或其他文件粘贴的？你知道吗

如果我对这个挑战没有感觉的话，我会修正格式上的小不一致，并且可能会想出更简单的方法。但有什么好玩的。。。你知道吗
