Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Frequency Distribution of Trigrams in Python NLTK The counts of different ngrams can be found by using nltk.probability.FreqDist. With the help of nltk.tokenize.ConditionalFreqDist() method, we are able to count the frequency of words in a sentence by using tokenize.ConditionalFreqDist() method. N()ifn==0:return0returnself[sample]/n.
