title: How to extend Python class init
body: <p>I have created a base class:</p>
  
  <pre><code>class Thing():
      def __init__(self, name):
          self.name = name
  </code></pre>
  
  <p>I want to extend the class and add to the <strong>init</strong> method so the that <code>SubThing</code> has both a <code>name</code> and a <code>time</code> property.  How do I do it?</p>
  
  <pre><code>class SubThing(Thing):
      # something here to extend the init and add a "time" property
  
      def __repr__(self):
          return '&lt;%s %s&gt;' % (self.name, self.time)
  </code></pre>
  
  <p>Any help would be awesome.</p>
