python - python中文本周围的动态边框

Question

我需要输入一个句子并在该句子周围制作一个动态边框。边框需要有输入的宽度。当句子的长度高于给定的宽度时，必须打印一个新行并且边框的高度 必须改变。句子也必须在动态边框中居中

我已经试过了:

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) + '-+')

但是随后每个带有新行的字母都被打印出来，这不是我需要的。

下面是一个很好的例子；

输入

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

输出

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

Answer 1

如果你想避免在中间断词，你也可以使用 textwrap.wrap:

from textwrap import wrap

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

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

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

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

输出:

+----------------------------+
|  You are only young once,  |
| but you can stay immature  |
|       indefinitely.        |
+----------------------------+
