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):&nbsp; &nbsp; result = []&nbsp; &nbsp; words = message.split()&nbsp; &nbsp; chunk = words.pop(0)&nbsp; &nbsp; for word in words:&nbsp; &nbsp; &nbsp; &nbsp; if len(chunk + word) >= size:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; result.append(chunk)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; chunk = word&nbsp; &nbsp; &nbsp; &nbsp; else:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; chunk = " ".join((chunk, word))&nbsp; &nbsp; result.append(chunk)&nbsp; &nbsp; return resultmessage = "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.']

更新 elif 块：elif len(text) > size:&nbsp; &nbsp; &nbsp; &nbsp; current_size = size&nbsp; &nbsp; &nbsp; &nbsp; while len(text)>size:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; texts = ''.join(text[:current_size])&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if texts[-1] == ' ' or text[:size + 1] == ' ':&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; sms_text.append(texts)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; text = text[current_size:]&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; current_size = size&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; current_size = current_size - 1Output : ['Your task is to ', 'develop a function ', 'that takes']
