AttributeError: 'FreqDist' object has no attribute 'inc'

Question

I am a beginner in Python and NLTK. I am trying to run the following code from a tutorial:

from nltk.corpus import gutenberg
from nltk import FreqDist

fd =          


        

Answer 1

For people looking for how to change the book example to NLTK 3.0:

import nltk
from nltk.corpus import brown

suffix_fdist = nltk.FreqDist()
for word in brown.words():
    word = word.lower()
    suffix_fdist[word[-1:]] +=1
    suffix_fdist[word[-2:]] +=1
    suffix_fdist[word[-3:]] +=1
common_suffixes = []
for suffix in suffix_fdist.most_common(100):
    common_suffixes.append(str(suffix.__getitem__(0)))
print common_suffixes
