Python - 文字換行

當從某些來源獲取的文字無法正確格式化以在可用的螢幕寬度內顯示時，需要進行文字換行。這透過使用以下程式包實現，可以透過以下命令安裝在我們的環境中。

pip install parawrap

下面的段落有一段連續的文字字串。應用 wrap 函式後，我們可以看到文字是如何被分隔成多行，並用逗號分隔。

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)

當我們執行上面的程式時，我們將得到以下輸出 −

我們還可以應用 wrap 函式，其中特定寬度作為輸入引數，這將在需要時截斷單詞以保持 wrap 函式所需的寬度。
