When to use __getattr__
<p>I came across the <code>__getattr__</code> built-in and was wondering when it would be used. I had a hard time thinking of a practical use from the documentation<br>
<a href="http://docs.python.org/reference/datamodel.html#" rel="nofollow">http://docs.python.org/reference/datamodel.html#</a>. What would be an actual example of how it could be used and useful in code?</p>
