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.

Swipe to start coding

Create a new empty column called "sentiment_predicted".
Use the .iterrows() method to iterate over the DataFrame.
Append the result of the polarity function for a specific index.

Oplossing

from textblob import TextBlob

import pandas as pd

# Create a new column to store the sentiment

data["sentiment_predicted"] = ""

# Iterate through the rows of the DataFrame

for index, row in data.iterrows():

# Create a TextBlob object

blob = TextBlob(row["text"])

# Get the sentiment of the text

sentiment = blob.sentiment.polarity

# Add the sentiment to the DataFrame

data.at[index, "sentiment_predicted"] = sentiment

# Print the DataFrame
