python - 在字符串切片中包含完整的单词

Question

这是我的一些代码:

def breakUp(x,chunk_size):
    return [ x[i:i+chunk_size] for i in range(0, len(x), chunk_size) ]

这是它的工作原理:

In [8]: breakUp('This is a cool sentence... How about eating it??? Whats more?? pepper is available all for free!!!',10)

Out[8]: 
['This is a ',
 'cool sente',
 'nce... How',
 ' about eat',
 'ing it??? ',
 'Whats more',
 '?? pepper ',
 'is availab',
 'le all for',
 ' free!!!']

但是正如你在第二个元素中看到的那样，句子这个词并没有完全被使用，它说的是“sente”......

我知道这是因为我已经要求 python 在每 10 个字符之后拆分它...是否有指定我想在每 10 个字符之后拆分但如果第 10 个字符。以一个词结尾，取整个词...？

Answer 1

包括电池:

>>> import textwrap
>>> print textwrap.fill('This is a cool sentence... How about eating it??? Whats more?? pepper is available all for free!!!', 15)
This is a cool
sentence... How
about eating
it??? Whats
more?? pepper
is available
all for free!!!

这几乎可以满足您的所有要求。除了如果您将 10 指定为第二个参数，它仍将拆分 sentence... 因为无法将其放入 10 个字符中。但是，如果您想这样做，您可以使用 break_long_words=False 自定义 textwrap:

>>> print textwrap.fill('This is a cool sentence... How about eating it??? Whats more?? pepper is available all for free!!!', 10, break_long_words=False)
This is a
cool
sentence...
How about
eating
it???
Whats
more??
pepper is
available
all for
free!!!
