title: Simple python regex, match after colon
body: <p>I have a simple regex question that's driving me crazy.
  I have a variable <code>x = "field1: XXXX field2: YYYY"</code>.
  I want to retrieve <code>YYYY</code> (note that this is an example value).
  My approach was as follows:</p>
  
  <pre><code>values = re.match('field2:\s(.*)', x)
  print values.groups()
  </code></pre>
  
  <p>It's not matching anything. Can I get some help with this? Thanks!</p>
