Description
This presentation is to explain type and object concept in Python object model. To understand the type and object is useful when you try to understand metaclass proramming in Python, especially when you are confused the attribute you want to modify is a type attribute or a class attribute or a object attribute. I would like to introduce how an object be created and how a class be created. then introduce how I write a meta class to trace all phase of creating an object. If you are new to meta class programming, you may want to check this slide 'What can meta class do for you'(http://www.slideshare.net/hychen/what-can-meta-class-do-for-you-pycon-taiwan-2012)
