TF-IDF implementations in python

Question

What are the standard tf-idf implementations/api available in python? I\'ve come across the one in nltk. I want to know the other libraries that provide this feature.

Answer 1

Unfortunately, questions asking for a tool or library are offtopic on SO. There are lot of machine learning libraries implementing tfidf. Two most comprehensive of them besides mentioned ntlk in my view are sklearn and gensim.
