Sentiment Classification

We finally made it to the final chapter of this project! Now that we know how to understand the sentiment of a tweet we will iterate over our DataFrame and append the results in a new column called "sentiment_predicted".

Methods description

• for index, row in data.iterrows():: Iterates through the rows of the DataFrame data;

• blob = TextBlob(row["text"]): Creates a TextBlob object for each text in the "text" column of the DataFrame;

• sentiment = blob.sentiment.polarity: Calculates the sentiment polarity of the text using the sentiment attribute of the TextBlob object. Polarity is a float value within the range [-1.0, 1.0], where negative values indicate negative sentiment, positive values indicate positive sentiment, and zero indicates neutral sentiment;

• data.at[index, "sentiment_predicted"] = sentiment: Assigns the calculated sentiment polarity to the "sentiment_predicted" column of the corresponding row in the DataFrame data using the at method.
