title: How to delete property?
body: <pre class="lang-py prettyprint-override"><code>class C():
      @property
      def x(self):
          return 0
  delattr(C(), 'x')
  </code></pre>
  
  <pre><code>&gt;&gt;&gt; AttributeError: can't delete attribute
  </code></pre>
  
  <p>I'm aware <code>del C.x</code> works, but this deletes the <em>class</em>'s property; can a class <em>instance</em>'s property be deleted? </p>
