What's the recommended 'design pattern' for exposing data via class variables?

Python properties are designed to resolve this issue.

Given your example you might want to take a look at sqlalchemy and its ORM. It does a lot of that work for you. It already maps columns as object attributes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
