[Tutor] Subclassing data attributes

Hi,
the module Data.py stores a number of data attributes. I'd like to structure the storage of these attributes, either in subclasses or in dictionaries.
My first attempt was this:
class A:
templates['attr1'] = 'string'
queries['children'] = ...
class B(A):
templates['attr2'] = 4
queries['children'] = ...
class C(B):
templates['attr3'] = 939.121
queries['populate'] = ...
Python obviously complains about unknown names 'templates' and 'queries'.
So I thought about realizing this with classes:
class A:
class Templates:
attr1 = 'string'
...
The problem here is that once an object uses class C.Templates to lookup attr3, it will not consult class A.Templates for attr1.
How can I avoid a complete inheritance mess and structure all my data attributes at the same time?
Thanks,
Jan
