To extract and analyze Reddit and Twitter posts, you need to install the necessary dependencies and API credentials.A package is provided to scrape Reddit posts by keyword or subreddit.For example, you can fetch 10 posts about 'AI' from r/technology over the last week or retrieve 5 top posts from r/worldnews in the last 24 hours.To scrape tweets from Twitter, a similar approach is used, where you can fetch recent tweets containing a specific keyword.
