使用正則表達式在特定模式前插入回車

Question

我在這里抓取了一個網站，結果如下：

when moist which dry to form dark spots.Stem: Off-white. Mealy towards 
the apex.Spores: Clay-brownFlesh: Firm, white. Smell of

我需要在冒號前面的單詞之前添加一個馬車，例如。 \\r\\nGills：為了使信息更具可讀性。

re.sub() 是最好的方法嗎？

Answer 1

text_with_rc=re.sub(r'\.\s*',r'.\r\n',the_text)

Answer 2

是的，這需要 re.sub。 試試下面的模式

str1=re.sub(r'(\w*:)',r'\r\n\1',string)
>>> print str1
