python
def get_user_tweets(username, count=10):
tweets = api.user_timeline(screen_name=username, count=count, tweet_mode='extended')
for tweet in tweets:
print(f"{tweet.user.name}: {tweet.full_text}\n")
This function takes a username and the count of tweets to retrieve and prints each tweet along with the user’s name.
Searching Tweets
To search for tweets containing specific words, use the following function:
python
def search_tweets(keyword, count=10):
tweets = api.search(q=keyword, count=count, tweet_mode='extended')
for tweet in tweets:
print(f"{tweet.user.name}: {tweet.full_text}\n")
This function fetches tweets that match the keyword provided.
2. Pulling User Data
In addition to tweets, you might also want to gather user information. Here’s how you can do it:
python
def get_user_info(username):
user = api.get_user(screen_name=username)
user_info = {
'Name': user.name,
'Location': user.location,
'Followers': user.followers_count,
'Following': user.friends_count,
'Tweets': user.statuses_count,
'Bio': user.description
}
return user_info
This function retrieves the specified user’s details and returns them in a dictionary.
Storing Data in Pandas DataFrame
Once you’ve pulled the data from Twitter, you may want to analyze it or manipulate it further. Using the pandas library makes this process much more manageable.
Creating DataFrames
You can convert the tweets and user data into a pandas DataFrame:
python
def tweets_to_dataframe(tweets):
data = {'User': [], 'Tweet': [], 'Created At': []}
for tweet in tweets:
data['User'].append(tweet.user.name)
data['Tweet'].append(tweet.full_text)
data['Created At'].append(tweet.created_at)
return pd.DataFrame(data)
This function collects the user names, tweet content, and time of creation into a structured DataFrame for analysis.
Analyzing the Data
With your data in a DataFrame, you can perform various analyses. Here’s a simple sentiment analysis example using the TextBlob library.
Performing Sentiment Analysis
“`python
from textblob import TextBlob
def analyze_sentiment(tweet):
analysis = TextBlob(tweet)
return analysis.sentiment.polarity
Apply sentiment analysis to the DataFrame
df[‘Sentiment’] = df[‘Tweet’].apply(analyze_sentiment)
“`
This example utilizes the TextBlob library to analyze the sentiment of each tweet, adding a new column to the DataFrame representing the sentiment polarity.
