Question

I have scraped a website here is the result:

Viscid when wet.Gills: Pale clay-brown. Free. Gill edge exude droplets 
when moist which dry to form dark spots.Stem: Off-white. Mealy towards 
the apex.Spores: Clay-brownFlesh: Firm, white. Smell of 
radishesHabitat: In groups or rings on the ground in mixed 
woodlandFrequency: Very Common

I need to add a carriage before the words which precede the colon eg. \\r\\nGills: in order to make the information more readable.

Is re.sub() the best way to do this?

Answer 1

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

Answer 2

Yes re.sub is required for this. Try the below pattern

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