NLTK stands for Natural Language ToolKit.
NLTK is a Python library used for human natural language processing. The biggest advantage of NLTK is that, it provides programmatical interface to over 100 lexical resources and corpora. Which means, from within your python program, you can use those corpora.
To install NLTK library, run the following pip command.
pip install -U nltk
