Python工具/软件包，从文本文件中的问答选项中生成测验

Question

我有一个文本文件，该文件在以下模式中有30个多项选择问题

1. 问题一个问题吗？

   a。选项1

   b。选项2

   c。选项3

   d。选项4

等于30

选项数量是可变的；至少有两个和最多六个选项。

我想在诸如HTML/PHP测验之类的接口中练习这些问题，该界面使我可以选择选项并终于显示结果。

我尝试在python中读取文件，然后尝试将问题和答案存储在单独的列表中，但它不起作用。以下是我的代码：

#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]

mcq.readlines（）输出到问题编号。3在下面给出注意：实际上有多个线路断路，因此文件结构不正确。

Answer 1

您可以尝试：

question =[]
mcq = open(mcq_file, "r")
data_list = mcq.readlines()  
for data in data_list:
    data = data.strip() #removes white space
    first_part = data.split(".")[0] 
    if first_part.isnumeric():
        # This is question and you can append this in question list
        question.append(data)

Answer 2

希望这可以做您想要的。有一些小错误，因为MCQS.TXT中的格式是不可预测的。例如，在问题5中，答案出现了。当我们选择容纳问题26的较低案例的答案选择时，我们将一个邪恶交换为另一个邪恶，这就是为什么问题3答案选择看起来很奇怪（"网站。"one_answers"主板"。以" e。"one_answers" d结尾"。"）。同样，问题25是编写2 n 5.这就是为什么偶尔在输出中串联的单独单词的原因。我很想知道原始文档的格式以及为什么它如此混乱？这些错别字还是您从PDF粘贴或其他？

#Get text into workable format
txt=open(r"mcqs.txt","r").readlines()

    while j<len(list_of_separators):
        sep=list_of_separators[j]
        if sep in txt1[i:i+len(sep)+1] or sep.lower() in txt1[i:i+len(sep)+1]:
            index=i+len(sep)

如果我不为挑战感到满意，我会以格式修复小小的矛盾性，并且可能会提出一些简单的事情。但是，这是什么乐趣...
