python中文本周围的动态边框

问题内容：

我需要输入一个句子，并在该句子周围添加动态边框。边框需要具有输入的宽度。当句子的长度大于给定的宽度时，必须打印新行，并且边框的高度
必须改变。句子也必须以动态边界为中心

我已经尝试过了：

sentence = input()
width = int(input())

length_of_sentence = len(sentence)

print('+-' + '-'*(width) + '-+')

for letter in sentence:
    print('| {0:^{1}} |'.format(letter, width - 4))

print('+-' + '-'*(width) + '-+')

但是，每个带有换行符的字母都会被打印出来，这不是我所需要的。

以下是一个很好的例子；

输入值

sentence = "You are only young once, but you can stay immature indefinitely."
width = 26

输出量

+----------------------------+
| You are only young once, b |
| ut you can stay immature i |
|         ndefinitely.       |
+----------------------------+

问题答案：

因此，您希望将字符串拆分为width字母块，而不是按字母输入。采取公认的答案：

def chunkstring(string, length):
    return (string[0+i:length+i] for i in range(0, len(string), length))

sentence = input('Sentence: ')
width = int(input('Width: '))

print('+-' + '-' * width + '-+')

for line in chunkstring(sentence, width):
    print('| {0:^{1}} |'.format(line, width))

print('+-' + '-'*(width) + '-+')

示例运行：

Sentence: You are only young once, but you can stay immature indefinitely. 
Width: 26
+----------------------------+
| You are only young once, b |
| ut you can stay immature i |
|       ndefinitely.         |
+----------------------------+
