To analyze Twitter sentiment using Python, you’ll need two main libraries:

• Tweepy: A Python library that helps access the Twitter API.

pip install tweepy

• TextBlob: A Python library used for text processing and sentiment classification.

pip install textblob
python -m textblob.download_corpora

These tools will give you everything you need to start collecting and analyzing tweets.

Authentication Process

To fetch tweets from Twitter’s API, you need to register the app with your Twitter account and set up your credentials:

• Go to the Twitter developer portal. Create a new app and fill in the details.
• After creating the app You will receive a consumer key.
• Consumer secrets Access token and the secret of the access token Keep these things handy as they are essential for validating your app.

Implementing Sentiment Analysis in Python

Here’s how to set up your sentiment analysis:

• Authenticate and connect to Twitter: First, create a class to handle authentication and connect to the Twitter API.
• Clean up tweets: Remove special characters, URLs, or mentions using simple regular expressions.
• Classify sentiment: Use TextBlob to analyze tweets and classify them as positive, negative, or neutral.

Sample Code:

import re
import tweepy
from tweepy import OAuthHandler
from textblob import TextBlob

class TwitterClient(object):
    def __init__(self):
        consumer_key = 'YOUR_CONSUMER_KEY'
        consumer_secret = 'YOUR_CONSUMER_SECRET'
        access_token = 'YOUR_ACCESS_TOKEN'
        access_token_secret = 'YOUR_ACCESS_TOKEN_SECRET'

        try:
            self.auth = OAuthHandler(consumer_key, consumer_secret)
            self.auth.set_access_token(access_token, access_token_secret)
            self.api = tweepy.API(self.auth)
        except:
            print("Error: Authentication Failed")

    def clean_tweet(self, tweet):
        return ' '.join(re.sub("(@[A-Za-z0-9]+)|([^0-9A-Za-z \t])|(\w+:\/\/\S+)", " ", tweet).split())

    def get_tweet_sentiment(self, tweet):
        analysis = TextBlob(self.clean_tweet(tweet))
        if analysis.sentiment.polarity > 0:
            return 'positive'
        elif analysis.sentiment.polarity == 0:
            return 'neutral'
        else:
            return 'negative'

    def get_tweets(self, query, count = 10):
        tweets = []
        try:
            fetched_tweets = self.api.search(q = query, count = count)
            for tweet in fetched_tweets:
                parsed_tweet = {}
                parsed_tweet['text'] = tweet.text
                parsed_tweet['sentiment'] = self.get_tweet_sentiment(tweet.text)
                if tweet.retweet_count > 0:
                    if parsed_tweet not in tweets:
                        tweets.append(parsed_tweet)
                else:
                    tweets.append(parsed_tweet)
            return tweets
        except tweepy.TweepError as e:
            print(f"Error: {str(e)}")

Output Example:

• Positive tweets percentage: 22% .
• Negative tweets percentage: 15% .

This helps you understand public opinion on various issues quickly and efficiently.
