title: Replying to a specific user with Tweepy
body: <p>I'm a complete noob when it comes to writing bots, so forgive me for my ignorance. I'd like to write a bot that automatically replies to a specific user. Every time they tweet, I want my bot to reply. I know for a fact that it's possible, I just don't know how to do it. I don't even know where to start. I created my Twitter app, I got the token access token codes, but what do I do next? Any help would be greatly appreciated.</p>
