title: How to get tweets author with tweepy
body: <p>I have a twitter bot which auto enters twitter giveaways, but most giveaways you need to tag and friend or 2, 
   I have it so it follows, likes and retweets but i cannot get it to reply</p>
  
  <pre><code>if ("tag" in tweet.text or "TAG" or "reply"):
    try: 
       api.update_status('@' + tweet.author + '@example1, @example2')
    except Exception:
         pass
  </code></pre>
  
  <p>this does not work 
  any ideas?</p>
