Need help. Some OOP issues.

Question

Hi.
I'm trying to get better understanding of OOP.
in this code, I used classes, inheritance and classmethod to calculate area and volume of some 3D objects. Simply I think it could be way better than this. I have some questions too:
1- is it ok to manipulate cls in classmethod to reach the goal as I did in area and volume of sphere?
2- is there any way to calculate area and volume of sphere, using only 1 object (like cube1) instead of 2 (sp1 and sp2)
3- how can I recall class attributes in print, so there will be no need to type it twice? (cuboid(2,3,5))
Thanks for helping.

Answer 1

1. I don't see the problem, does it work? Yeah? Then it's good. That's all.

2. Just create an object "sp" (sp = Cylinder()) and call "sp.sphere_area()" and "sp.sphere_volume()".

3. Just create a string with your content (e.g. str = f'Cuboid({cubo1.x}, {cubo1.y}, {cubo1.z})') and use it twice. You could also define the __str__ method to return the object in your string format and just do print(cube1).

Answer 2

OrHy3 thanks a lot.
I managed to recall class attributes in print utilizing both methods, thanks to you.
Also I corrected the code as you suggested to use only 1 object: sp. however, there's a problem using this: sphere needs 2 arguments as a class of Cylinder. Meaning that we need radius and height to calculate area and volume of sphere, which height is obviously irrelevant here.
