>>> from afinn import Afinn >>> afinn = Afinn() >>> afinn.score('This is utterly excellent!') 3.0
>>> afinn = Afinn(language='da') >>> afinn.score('Hvis ikke det er det mest afskyelige flueknepperi...') -6.0
>>> 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, 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 .
