Sentence tokenizer not working on Full stop

[shivambatra76]

I have given the following input to

from summa.preprocessing.textcleaner import clean_text_by_sentences as _clean_text_by_sentences.

text='''Ad sales boost Time Warner profit
Quarterly profits at US media giant TimeWarner jumped 76% to $1.13bn (£600m) for the three months to December, from $639m year-earlier.The firm, which is now one of the biggest investors in Google, benefited from sales of high-speed internet connections and higher advert sales. TimeWarner said fourth quarter sales rose 2% to $11.1bn from $10.9bn. Its profits were buoyed by one-off gains which offset a profit dip at Warner Bros, and less users for AOL.
'''
This is the output i have recieved from after preprocessing. As you can see the second sentence should get separated by full stop but instead it is only separating the sentence using space on a new line by enter key pressed.
