     ('I love this sandwich.', 'pos'),
     ('This is an amazing place!', 'pos'),
     ('I feel very good about these beers.', 'pos'),
     ('I do not like this restaurant', 'neg'),
     ('I am tired of this stuff.', 'neg'),

 ]
cl = NaiveBayesClassifier(train)
 cl.classify("I feel amazing!")

Here is the output

'pos'

How can i get the score of this like pos .7 or in any other format

Answer 1

You can do something like the following: source here

>>> prob_dist = cl.prob_classify("I feel amazing!")
>>> prob_dist.max()
'pos'
>>> round(prob_dist.prob("pos"), 2)
0.63
>>> round(prob_dist.prob("neg"), 2)
0.37
