Python中求字符串中最长的单词

可以使用split()函数将字符串分割成单词列表，然后遍历列表找到最长的单词即可。以下是示例代码：

def find_longest_word(s):
    words = s.split()
    longest_word = ""
    for word in words:
        if len(word) > len(longest_word):
            longest_word = word
    return longest_word

s = "Python is a powerful and easy-to-learn programming language."
longest_word = find_longest_word(s)
print("The longest word is:", longest_word)

输出结果为：

The longest word is: programming
