title: Python inheritance old style type in a new style class
body: <p>I'm using the <code>csv.DictWriter</code> class, and I want to inherit it:</p>
  
  <pre><code>class MyObj(csv.Dictwriter):
      ...
  </code></pre>
  
  <p>But this type is an old-style object. Can <code>MyObj</code> be a new-style class but still inherit from <code>csv.DictWriter</code>?</p>
