行文字列のリストに分割する必要がある長い文字列（複数の段落）があります。「線」を作るものの決定は以下に基づいています：

  • 行の文字数がX以下（Xは1行あたりの固定列数_）
  • または、元の文字列に改行があります（これにより、新しい「行」が強制的に作成されます。

私はこれをアルゴリズムで実行できることを知っていますが、Pythonにこのケースを処理できるものがあるかどうか疑問に思っていました。これは基本的に文字列をワードラップすることです。

ちなみに、出力行は文字の境界ではなく、単語の境界で分割する必要があります。

入力と出力の例を次に示します。

入力：

"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."

あなたが探しているのはtextwrapですが、それはソリューションの一部にすぎず、完全なものではありません。改行を考慮するには、次のようにする必要があります。

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()])

おそらく、標準ライブラリの textwrap 関数を使用したいと思うでしょう:
