First download facebook data and store it in excel file.
We are using:-
=> pandas library:-it provides easy to use data structures for data analysis.
=>NLTK library:-this is used to process human language.
=>nltk also provides sentiment analysis of human data.

it also takes into account the intensity of the sentiment.
So VADER lexicon acts as a dictionary here.
It's Just Mindblowing ...
