Python函数消息格式化程序

Question

我的任务是开发一个函数，该函数接收字符串消息并在需要时返回带有分页的字符串消息数组。对于本练习，输入消息中的最大字符数为 160。此外，不要将单词分成音节和连字符。我的功能没有满足不分词的功能def sms_format(message, size):    sms_text = []    if len(message) == 0:        return sms_text    text = list(message)    if len(text) <= size:        new_text = ''.join(text)        sms_text.append(new_text)    elif len(text) > size:        while len(text)>size:            texts = ''.join(text[:size])            sms_text.append(texts)            text = text[size:]        sms_text.append(''.join(text))    return(sms_text)message = "Your task is to develop a function that takes"print(sms_format(message, 20))实际结果： ['Your task is to deve', 'lop a function that ', 'takes']预期结果：它不应该破坏单词

Answer 1

这似乎工作正常：

def sms_format(message, size):

    result = []

    words = message.split()

    chunk = words.pop(0)

    for word in words:

        if len(chunk + word) >= size:

            result.append(chunk)

            chunk = word

        else:

            chunk = " ".join((chunk, word))

    result.append(chunk)

    return result

message = "Your task is to develop a function that takes long text, and splits it into chunks."

print(sms_format(message, 20))

给出：

['Your task is to', 'develop a function', 'that takes long', 'text, and splits it', 'into chunks.']

Answer 2

更新 elif 块：

elif len(text) > size:

        current_size = size

        while len(text)>size:

            texts = ''.join(text[:current_size])

            if texts[-1] == ' ' or text[:size + 1] == ' ': 

                sms_text.append(texts)

                text = text[current_size:]

                current_size = size

            else:

                current_size = current_size - 1

Output : ['Your task is to ', 'develop a function ', 'that takes']
