title: Python Regex Twitter username including @
body: <p>So I have found this regex:</p>
  
  <pre><code>(?&lt;=^|(?&lt;=[^a-zA-Z0-9-_\.]))@([A-Za-z]+[A-Za-z0-9-_]+)
  </code></pre>
  
  <p>from this question: <a href="https://stackoverflow.com/questions/2304632/regex-for-twitter-username">regex for Twitter username</a></p>
  
  <p>But this ignores the actual "@" in the handle when returning. I've tried to edit this to include @ without success. I want to return "@username" instead of "username". How do I edit this regex to include "@"?</p>
