我尝试使用问题文件进行测验，并在两个答案文件之间进行选择。我将让用户在打印所有问题和答案之间做出选择，或者只是随机生成一些问题和答案。我的问题是我无法按预期显示它。我需要它显示如下：
1. how many... etc.
a.answer
b.answer
c.answer
d.answer
e.none of the above
但我无法获得正确的输出。文本文件包含如下答案：
C,3,4,5,6
A,4O,30,20,10
E,65,245,456,756
所以我用空格替换了逗号，并且通过使用\ n代替空格成功地将它们显示为一行而不是一行...但它不会起作用，因为一些答案不止一个字。我还需要在答案之前删除这封信（这是正确的答案）并将其放入一个列表中，我真的不确定如何做到这一点。

答案 0 :(得分：2)
对于没有逗号的答案集，如何：
import string
chars1= string.ascii_lowercase
answers=answerList[randomnum].strip().split(',')[1:] #removes the answer letter
answers.append('none of the above')
print '\n'.join(chars1[i]+'. '+answers[i] for i in range(len(answers)))
声明：
chars1[i]+'. '+answers[i],
在每个答案的开头添加一个字符，并且作为string.ascii_lowercase ='abcdefghijklmnopqrstuvwxyz'，这将为每个以'a'开头的答案提供字母字符。
如果有逗号，那么你必须将文件存储为完整的csv并使用csv模块加载文件，然后不使用上面代码中的拆分，只需使用提取的csv中的每一行。
