NLTK is a Python API for the analysis of texts written in natural languages, such as English. NLTK was created in 2001 and was originally intended as a teaching tool. Install NLTK with the following command:
$ sudo pip install nltk $ pip freeze|grep nltk nltk==2.0.4
As usual, we will check the installation with a new version of the pkg_check.py file. The following import statement is required:
import nltk
If everything works, we should get a result similar to the following:
