title: Regular Expression matching characters after a string
body: <p><strong>For the following expression</strong>: <code>^swlang/(\d{2})/$</code></p>
  
  <p>matches a string <code>swlang</code> followed by two digit of integers. </p>
  
  <p>Now to modify this expression so that it matches 2 characters instead.</p>
  
  <p>I tried: <code>^swlang/(\S{2})/$</code> but it doesn't seem to work.</p>
  
  <p>Note: I am trying to match a URL in django</p>
  
  <p>the full code looks like this</p>
  
  <pre><code>url(r'^swlang/(\d{2})/$', 'klip.views.swlang'),
  </code></pre>
  
  <p>So for example, a url that is going to be routed to <code>klip.views.swlang</code>
  would be <code>example.com/swlang/43</code></p>
  
  <p>The desired one may look like <code>example.com/swlang/en</code></p>
