title: Why is object.__getattr__ missing?
body: <p>Why does <code>object</code> seem not to have a <code>__getattr__</code> method?  It defines both <code>__setattr__</code> and <code>__delattr__</code>.  Doesn't it need all three?</p>
  
  <pre><code>&gt;&gt;&gt; object.__setattr__
  &lt;slot wrapper '__setattr__' of 'object' objects&gt;
  &gt;&gt;&gt; 
  &gt;&gt;&gt; object.__delattr__
  &lt;slot wrapper '__delattr__' of 'object' objects&gt;
  &gt;&gt;&gt; 
  &gt;&gt;&gt; object.__getattr__
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  AttributeError: type object 'object' has no attribute '__getattr__'
