Have you read the following?

# setattr, getattr, delattr:
http://www.python.org/doc/lib/built-in-funcs.html

# __setattr__ etc.
http://www.python.org/doc/ref/attribute-access.html

If there is anything unclear about the descriptions, please ask.

In a nutshell, like all double-underscore methods, __setattr__ are for 
overriding behaviour in your own classes. With very few exceptions, you 
shouldn't need to directly call double-underscore methods (although you 
often may _write_ double-underscore methods).
