Question

完整的问题是“编写一个函数find_longest_word（），它带有一个单词和列表返回最长的单词和长度。您还应该编写测试函数这将要求用户输入单词列表并打印最长的单词及其长度。“

我写了这段代码并且它有效。我只需要弄清楚如何在这段代码中添加一个函数，以便我在问题中告诉我。

def main():
    text = input("Please input a list of words to evaluate: ")

    longest = 0

    for words in text.split():
        if len(words) > longest:
            longest = len(words)
            longest_word = words

    print("The longest word is", longest_word, "with length", len(longest_word))

main()

Answer 1

只需将逻辑移动到一个函数中，就像这样

def find_longest_word(text):
    for words in text.split():
        if len(words) > longest:
            longest = len(words)
            longest_word = words
    return longest_word, len(longest_word)

def main():
    input_string = input("Please input a list of words to evaluate: ")
    longest_word = find_longest_word(input_string)
    print("The longest word is", longest_word, "with length", len(longest_word))

您尝试解决的实际问题可以像这样解决

def find_longest_word(text):
    longest_word = max(text.split(), key = len)
    return longest_word, len(longest_word)

注意：我们不是在find_longest_word函数中打印结果，而是从它返回longest_word，这样函数只会执行它应该执行的操作。现在，顾名思义，它只找到最长的单词。

使用简短的编解码器练习....

def main():
    a = sorted(input("Please input a list of words to evaluate: ").split(), key=len) [-1]
    print ("You longe word ", str(a), " have this", str(len(a)), "lenghts")

main()

Answer 3

您不需要longest_word = words，但如果没有您的答案，则无法回答此练习....，谢谢！

def main ():
    text = input("Please input a List of words to evaluate: ")

    longest = 0

    for words in text.split():
           if len(words) > longest:
                  longest = len(words)
    print ("The longest word is", words, "with lenght", longest)


main()

Answer 4

def find_longest_word(words_list):  
    word_len = []  
    for n in words_list:  
        word_len.append((len(n), n))  
    word_len.sort()  
    return word_len[-1][1]  

print(find_longest_word(["hasta ", "lavista", "baby"]))

Answer 5

这是一个python程序，用于读取单词列表并返回最长的单词的长度：

list_words = ["PHP", "Exercises", "Backend"]<br/>
s = [(len(word),word) for word in list_words] <br/>
s.sort() <br/>
print('Longest String in list is ',s[-1][1]) <br/>

Answer 6

numberOfWordsInList = int(input("Enter number of words to be List: "))

def longestWordInList(numberOfWordsInListt):
    createdList = [input("Enter any word: ") for i in range(numberOfWordsInList)]    
    lengthOfItems = [(len(items), items) for items in createdList]
    return max(lengthOfItems)

print(longestWordInList(numberOfWordsInList))

编写一个函数，该函数获取单词列表并返回最长单词和最长单词的长度
