What is a "dynamic" and what is a "static" attribute ????

Please start with learning Python's execution model (what exactly 
happens at runtime, what most statement are syntactic sugar for etc) and 
Python's object model (how are Python objects, classes, methods etc 
implemented, attributes lookup rules, metaclasses, descriptors etc).

Then PERHAPS you MIGHT have a chance to help making Python "more perfect".
