OOP: using class vs instance (Python)
===

I'm asking this question with regards to Python, though it's probably applicable to most OOP languages.  When I only expect to use the data model only once in any program, I could either make a class with class/static methods and attributes or just make a regular class and instantiate it once and only use that one copy.  In this case, which method is better and why?

With python, I could also write a module and use it like I would a class.  In this case, which way is better and why?
