Python 文本换行
当从某个来源抓取的文本格式不正确以显示在可用的屏幕宽度内时，需要进行文本换行。这是通过使用以下软件包来实现的，该软件包可以使用以下命令安装在我们的环境中。
pip install parawrap
下面的段落有一个连续的文本字符串。在应用 wrap 函数时，我们可以看到文本是如何分成多行并用逗号分隔的。
import parawrap text = "In late summer 1945, guests are gathered for the wedding reception of Don Vito Corleone's daughter Connie (Talia Shire) and Carlo Rizzi (Gianni Russo). Vito (Marlon Brando), the head of the Corleone Mafia family, is known to friends and associates as Godfather. He and Tom Hagen (Robert Duvall), the Corleone family lawyer, are hearing requests for favors because, according to Italian tradition, no Sicilian can refuse a request on his daughter's wedding day. One of the men who asks the Don for a favor is Amerigo Bonasera, a successful mortician and acquaintance of the Don, whose daughter was brutally beaten by two young men because she refused their advances; the men received minimal punishment from the presiding judge. The Don is disappointed in Bonasera, who'd avoided most contact with the Don due to Corleone's nefarious business dealings. The Don's wife is godmother to Bonasera's shamed daughter, a relationship the Don uses to extract new loyalty from the undertaker. The Don agrees to have his men punish the young men responsible (in a non-lethal manner) in return for future service if necessary." print parawrap.wrap(text)
当我们运行上述程序时，我们得到以下输出：

我们还可以应用具有特定宽度的 wrap 函数作为输入参数，如果需要，它将剪切单词以保持 wrap 函数所需的宽度。
