我需要帮助使代码拆分句子。我将在我的代码中在哪里输入拆分函数

Question

目前我的代码适用于列表，但不适用于句子。我需要帮助将句子变成列表。我应该在哪里将 .split 函数输入到我的代码中？

def stats(word_list):
    'prints number, longest and average length of word_list'
    length = len(word_list)
    print("The number of words is {}.".format(length))
    char_count = 0
    longest_so_far = ""
    for word in word_list:
        # char_count = char_count + len(word)
        char_count += len(word)
        if len(word) > len(longest_so_far):
            longest_so_far = word

    print("The longest word is " + longest_so_far + ".")
    average = char_count / length
    message = "The average length is {}.".format(average)
    print(message)

您可以在函数的第一行执行此操作，当您传递一个字符串并执行 string.split 以生成您的 word_list

def stats(sentence):
    'prints number, longest and average length of word_list'

    #Split sentence to a list of words here
    word_list = sentence.split()

    length = len(word_list)
    print("The number of words is {}.".format(length))
    char_count = 0
    longest_so_far = ""
    for word in word_list:
        # char_count = char_count + len(word)
        char_count += len(word)
        if len(word) > len(longest_so_far):
            longest_so_far = word

    print("The longest word is " + longest_so_far + ".")
    average = char_count / length
    message = "The average length is {}.".format(average)
    print(message)

stats('i am a sentence')

输出将是

The number of words is 4.
The longest word is sentence.
The average length is 3.0.

你也可以如下优化你的代码

def stats(sentence):
    'prints number, longest and average length of word_list'

    #Split sentence here in word here
    word_list = sentence.split()
    length = len(word_list)

    print("The number of words is {}.".format(length))

    #Sort the word list on word length in reverse order
    sorted_word_list = sorted(word_list, key=len, reverse=True)

    #The longest element will be first element in that list
    print("The longest word is " + sorted_word_list[0] + ".")

    #Calcuate length of each word and sum all lengths together
    char_count = sum([len(w) for w in word_list])

    #Calculate average and print it
    average = char_count / length
    message = "The average length is {}.".format(average)
    print(message)

stats('i am a sentence')
