The objective of this code is to create a method called settings, which controls all the settings for the screen and the bouncing behaviour of multiple balls, under the class Ball. However, I keep on getting errors related to attributes (e.g., speed). I'm new to OOP in Python so your help will be much appreciated. Thanks in advance.

You are making a error that few in the programming community have caught up to.  OOP design for *data abstraction* is a completely different beast that OOP for *simulation*.  The confusion is around the use of the word "object" which both denotes a physical world item and a virtual one detached from reality.

I would say that Python might not be the right fit, but instead a language dedicated to simulation.
