How to handle exceptions properly in a pythonic way?

Personally, I never liked "early returns". I would rather used a variable and the last line in the function would be return variable.
Anyway, I got the point.

I got a picture. Thanks.

I have to rethink now about two approaches. One would be as you have suggested in this mail - raising ContentNotFoundError, and another one would be not to mask root exceptions and deal with them instead of ContentNotFoundError.

You have clarified to me the concept. Thanks.
