A code I am using as reference has the following line: from nltk.stem.lancaster import LancasterStemmer
I am inferring the following based on above: 1) nltk is a package 2) nltk itself may have module because I see - nltk.word_tokenize(pattern['sentence']) in the code 3) nltk has a package named stem which has another package named Lancaster that has LancasterStemmer package Somehow, I get confused with what is the package, module and function in third party packages like above. -- https://mail.python.org/mailman/listinfo/python-list
