检查文件python的值

Question

我不是专家或者只是初学者，但我在检查某个值时遇到问题，看它是否对文件是正确的，这是我现在的代码

line = open("question.txt", "r").readlines()[0]
secondline = open("answer.txt", "r").readlines()[0]
print("Please enter A or B for the correct answer")
answer = input("What does "+ line + " mean? \n A: set of rules \n B: a 
program ").upper()
if answer == (secondline):
    print("Well done")
else:
    print("incorrect")

what outputs is: 
Please enter A or B for the correct answer
What does algorithm mean? 
A: set of rules 
B: a program a
incorrect
>>> 

'问题'文本文件仅包含第一行的算法 并且'回答'文本文件在第一行只有'a'。

请帮忙！谢谢。

要使此代码生效，您可以将upper()替换为lower()，或将answer.txt的内容更改为A。
