Sorry I meant "working with classes" vs "working with structures or
records".

I know that everything in Python is an object, but I was thinking of
building my own structures for storing information by using "classes", in a
OOP context.

There I realize that maybe I have to forget defining "classes" and just use
NumPy objects, for those heavy/intensive search and/or computing tasks in my
code.

[ Again, asking myself...: Do I miss something? I mean, actually, a NumPy
array has properties/attributes and methods... So, maybe using objects from
NumPy doesn't mean forget object oriented programming. I think I was a bit
confused about it... ]


Working with object or not is not generally the most relevant aspect of

That's true... In fact, for me, I think it's a matter of programming
style...
