title: Deriving class from `object` in python
body: <p>So I'm just learning python (I know plenty of other languages) and I'm confused about something. I think this is due to lack of documentation (at least that I could find). On a few websites, I've read that you should derive your classes from <code>object</code>:</p>
  
  <pre>
  <code>
  class Base(object):
      pass
  </code>
  </pre>
  
  <p>But I don't see what that does or why or when you should do it. Is there official documentation on this that I've missed? Is this a 3.x feature?</p>
