Question

如何才能使两个字符串正确比较？如果字符串Answers中包含'N'，那么会有输出吗？

def stringSearcher():             #Seperates and returns 2 strings from .txt file
    f = open("QuestionTree.txt", "r")
    currentLine = f.readline()
    for line in f:
        if Answer in line: 
            yesnos, answerOrQuestion = line.split(',')
            return answerOrQuestion, yesnos

while True:

    Answer = raw_input("Y or N: ")              #User input
    answerOrQuestion, yesnos = stringSearcher() #allows usage of Return variables

    if yesnos == Answer:     #Will compare the 'Y' in string but not 
        print answerOrQuestion

这是输出的样子：

Y or N: N    #Not print the N in the text file
Y or N: Y 
In the Towers?

Y or N: YN
Y or N: YY
Old Tower?

Y or N: YYY
7 floors tall?

Y or N: ^CTraceback (most recent call last):
  File "TestCode.py", line 11, in <module>
    Answer = raw_input("Y or N: ")

这就是文本文件的样子：

，这是宿舍吗？ Y，在塔楼？ YY，老塔？ YYY，7层高吗？ YYYY，是Carey吗？ YYYYY，Carey Hall YYYYN，特劳特曼大厅 YYYN，是惠勒吗？ N，西部的使命？纽约，布鲁姆菲尔德的S？ NYY，CMU拥有？ NYYY，Kewadin NYYN，B-Ball Court？ NYYNY，是列克星敦吗？

    for line in f:
        if re.match(Answer, line): 
            yesnos, answerOrQuestion = line.split(',')
            return answerOrQuestion, yesnos

while True:

    Answer = raw_input("Y or N: ")
    answerOrQuestion, yesnos = stringSearcher(Answer)

    if Answer == yesnos:     #Will compare the 'Y' in string but not 
        print answerOrQuestion

找到＆＃39; Y＆＃39;的出现？或者＆＃39; N＆＃39;在一个字符串中
