如何打印句子中的回文单词？如果我输入“夫人阿罗拉教数学”，它应该打印“夫人阿罗拉”

def is_palindrome(word):
    # 判断是否为回文单词
    left = 0
    right = len(word) - 1
    while left < right:
        if word[left] != word[right]:
            return False
        left += 1
        right -= 1
    return True

def print_palindromes(sentence):
    # 打印句子中的回文单词
    words = sentence.split(" ")
    result = []
    for word in words:
        if is_palindrome(word):
            result.append(word)
    print(" ".join(result))

sentence = input("请输入一个句子：")
print_palindromes(sentence)
