>>> afinn = Afinn(emoticons=True)
>>> afinn.score('I saw that yesterday :)')
2.0
With multiple sentences (here with data from an Austen novel available in Gutenberg):
>>> from afinn import Afinn
>>> from nltk.corpus import gutenberg
>>> import textwrap
>>> afinn = Afinn()
>>> sentences = (" ".join(wordlist) for wordlist in gutenberg.sents('austen-sense.txt'))
>>> scored_sentences = ((afinn.score(sent), sent) for sent in sentences)
>>> sorted_sentences = sorted(scored_sentences)
>>> print("\n".join(textwrap.wrap(sorted_sentences[0][1], 70)))
To attach myself to your sister , therefore , was not a thing to be
thought of ;-- and with a meanness , selfishness , cruelty -- which no
indignant , no contemptuous look , even of yours , Miss Dashwood , can
ever reprobate too much -- I was acting in this manner , trying to
engage her regard , without a thought of returning it .-- But one
thing may be said for me : even in that horrid state of selfish vanity
, I did not know the extent of the injury I meditated , because I did
not THEN know what it was to love .
