将没有换行符的字符串拆分为具有最大列数的行列表

我有一个长字符串(多个段落),需要将其拆分为一个字符串列表。“线条”的确定基于:

行中的字符数小于或等于x(其中x是每行固定的列数)
或者,原始字符串中有新行(这将强制创建新的“行”)。

我知道我可以从算法上实现这一点,但我想知道Python是否有可以处理这种情况的功能。它本质上是一个包裹字符串的单词。

而且,顺便说一下,输出行必须在单词边界上断开,而不是字符边界。

以下是输入和输出示例:

输入:

"Within eight hours of Wilson's outburst, his Democratic opponent, former-Marine Rob Miller, had received nearly 3,000 individual contributions raising approximately $100,000, the Democratic Congressional Campaign Committee said.

Wilson, a conservative Republican who promotes a strong national defense and reining in the size of government, won a special election to the House in 2001, succeeding the late Rep. Floyd Spence, R-S.C. Wilson had worked on Spence's staff on Capitol Hill and also had served as an intern for Sen. Strom Thurmond, R-S.C."

输出:

"Within eight hours of Wilson's outburst, his"
"Democratic opponent, former-Marine Rob Miller,"
" had received nearly 3,000 individual "
"contributions raising approximately $100,000,"
" the Democratic Congressional Campaign Committee"
" said."
""
"Wilson, a conservative Republican who promotes a "
"strong national defense and reining in the size "
"of government, won a special election to the House"
" in 2001, succeeding the late Rep. Floyd Spence, "
"R-S.C. Wilson had worked on Spence's staff on "
"Capitol Hill and also had served as an intern"
" for Sen. Strom Thurmond, R-S.C."

你要找的是 textwrap 但这只是解决方案的一部分,而不是完整的解决方案。要将newline考虑在内,您需要执行以下操作:

from textwrap import wrap
'\n'.join(['\n'.join(wrap(block, width=50)) for block in text.splitlines()])

>>> print '\n'.join(['\n'.join(wrap(block, width=50)) for block in text.splitlines()])

Within eight hours of Wilson's outburst, his
Democratic opponent, former-Marine Rob Miller, had
received nearly 3,000 individual contributions
raising approximately $100,000, the Democratic
Congressional Campaign Committee said.

Wilson, a conservative Republican who promotes a
strong national defense and reining in the size of
government, won a special election to the House in
2001, succeeding the late Rep. Floyd Spence,
R-S.C. Wilson had worked on Spence's staff on
Capitol Hill and also had served as an intern for
Sen. Strom Thurmond
