I would like to announce that two articles explaining in detail the working of new-style (v2.2 and up) objects have been released as final versions. 1. Python Types and Objects http://www.cafepy.com/articles/python_types_and_objects/ Explains different Python new-style objects, starting with <type 'type'> and <type 'object'>, and going all the way to user defined classes and instances. The system described is sometimes called the Python type system, or the object model. 2. Python Attributes and Methods http://www.cafepy.com/articles/python_attributes_and_methods/ Explains the mechanics of attribute access, how functions become methods, descriptors, properties, MRO and the like for new-style Python objects. Any and all feedback is appreciated, and can be sent to shalabh@cafepy.com. -- Shalabh Chaturvedi
