Hello,

Using the additional script for bigrams:

from nltk import bigrams
terms_bigram = bigrams(terms_stop)

How can I print the results from terms_bigram?

Thank you.

Hello BFrost888 ,
I hope the following code solves your problem

`terms_stop = [term for term in featureVector if term not in stopWords]
terms_bigram = bigrams(terms_stop)
for t in terms_bigram:
    print t `
