查找所有回文单词的程序只输出前两个单词

def is_palindrome(word):
    left = 0
    right = len(word) - 1
    while left < right:
        if word[left] != word[right]:
            return False
        left += 1
        right -= 1
    return True

text = input("请输入一段文本：")
words = text.split()

palindrome_words = []
for word in words:
    if is_palindrome(word):
        palindrome_words.append(word)

if len(palindrome_words) >= 2:
    print("前两个回文单词是：", palindrome_words[0], palindrome_words[1])
elif len(palindrome_words) == 1:
    print("只有一个回文单词：", palindrome_words[0])
else:
    print("没有回文单词。")
