使用者输入两个单词，程序判断两个单词是否为回文词，输出判断结果
def is_palindrome(word): return is_reversable_pair(word, word) def reverse_word(word): reversed_word = '' for i in range(len(word) - 1, -1, -1): reversed_word += word[i] return reversed_word def main(): print('This program determines if two words form a reversable pair.') word1 = input('Enter first word: ') word2 = input('Enter second word: ') if is_reversable_pair(word1, word2): print(word1 + ' and ' + word2 + ' form a reversable pair') else: print(word1 + ' and ' + word2 + ' do NOT form a reversable pair') if __name__ == '__main__': main()
