有没有可能找到一个文本文件中最长单词的长度，然后只用1个while循环就能读入同一个文本文件？

file_path = "example.txt"  # 文本文件路径
max_word_length = 0  # 最长单词的长度

with open(file_path, "r") as file:
    while True:
        line = file.readline()
        if not line:
            break  # 读取到文件末尾，退出循环
        words = line.split(" ")
        for word in words:
            word_length = len(word)
            if word_length > max_word_length:
                max_word_length = word_length

print("最长单词的长度为:", max_word_length)
