Case Study: Sentiment Analysis
As an example of a Data Science project, let's take a look at sentiment analysis using Python. Sentiment analysis is the process of determining whether a piece of text is positive, negative, or neutral.
Here's a simple example using the TextBlob library:
from textblob import TextBlob
text = "Python is a great programming language."
blob = TextBlob(text)
print(blob.sentiment)
