Python if statement not working

I have an if/else statement in python, and I want to do nothing when it goes to the else statement.

I am reading a list of words, finding the palindromes (eg 'abba') and printing them out. It currently prints out the entire list of words, and I know the is_palindrome function is working correctly.

def first(word):
    return word[0]

def last(word):
    return word[-1]

def middle(word):
    return word[1:-1]


def is_palindrome(word):
    #print(word)
    if len(word) >1:
        if first(word) == last(word):
            #print(word)
            #print(middle(word))
            return is_palindrome(middle(word))
        else:
            return False
    else:
        return True


try:
    words = open("/usr/share/dict/words","r")

    for line in words:
        line.strip()
        #print line
        if is_palindrome(line) == True:
            print(line)
    else
    words.close()
except:
    print("File open FAILED")

I'd appreciate any insight you could give me. Thanks.

'line.strip()' by itself won't change line. This ought to work.

for line in words:
    line = line.strip()
    if is_palindrome(line) == True:
        print(line)

words.close()
