Here we are going to identify the sentiment of a text using textbob and categorize them into positive or negative.

Python Code :-

# Import TextBlob
from textblob import TextBlob

text = "Python is a great tool"

obj = TextBlob(text)

# returns the sentiment of text,
# value between -1.0 to 1.0
sentiment = obj.sentiment.polarity
