First read this article http://effbot.org/zone/python-objects.htm and then  
this one http://effbot.org/zone/call-by-object.htm

There is a FAQ entry at  
http://www.python.org/doc/faq/programming/#how-do-i-write-a-function-with-output-parameters-call-by-reference

The Google interface is good for searching past messages on this topic:
