Class Inheritance

[Andrew Rekdal]

I am trying to bring functions to a class by inheritance... for instance in 
layout_ext I have..


--- layout_ext.py---------
class Layout()
    def...some function that rely on css in Layout.py
    def...

---EOF--

in the main application file I have...
----Layout.py---
from layout_ext import Layout
from CSS import CSS
css = CSS()
class Layout(Layout)
    def __init__
    more code.....

----EOF----


Problem is layout_ext and Layout code is dependant on a Class instance 
'css'. Whenever the CSS instance it parses a file, this means that I would 
have to parse the file twice?? Why is this? Can I do something like pass an 
already created instance to the import?
