Can someone provide an example why one would want to override __getattr__

They're good for cases when you want to provide an attribute-like
quality but you don't know the attribute in advance.
For example, the xmlrpclib uses __getattr__ to expose XML-RPC methods
over the wire when it doesn't necessarily know what methods are exposed
by the service. This allows you do simply do
service.method(*args)
And have the method seem like it's just a local method on an object.
There are countless other examples. But that's just one that can be
found in the standard library.
