getattr(b, 'foo') is the same as b.foo. getattr takes a string for the name of the attribute. So you would need getattr(getattr(b, x), y) > > Also, any suggestions for my overall structure below? For once I agree with Alan on a design question :-) You can define a useful structure directly in your configuration. It could be nested lists and dictionaries or nested class instances, whichever works better for the application. I think I would use nested class instances. This is one of Python's great strengths - that you can easily declare complex data structures in code. PS I suggest you call your data structure something other than 'database' since that word has a fairly specific meaning.
