title: re.groups() return nothing
body: <p>I am new to regex area ! I am trying to understand groups functionality.
  Here is my string: </p>
  
  <pre><code> ** server can\'t find mywebdomain.com: NXDOMAIN
  </code></pre>
  
  <p>Here is my regex:</p>
  
  <pre><code>match = re.match('[*]{2}\s+server.*NXDOMAIN')
  </code></pre>
  
  <p>Here is the value of the match I see in debugger: </p>
  
  <pre><code>match="** server can't find testweb.com: NXDOMA&gt;
  </code></pre>
  
  <p>So I am trying to see groups on this regex. </p>
  
  <pre><code>match.groups()
  </code></pre>
  
  <p>but it returns nothing for me while I would expect to get a tuple.
  so I do not really understand why it returns nothing?</p>
