================

Goals
-----

- Make use of **instance methods** to keep object logic organized and contained in the class.

Starter code

- :download:`using_classes_to_store_data.py <code/using_classes_to_store_data.py>`

Video Tutorial

What you need to do
-------------------

- Add the constraint on the y-axis to make the ball bounce on the top and bottom
- Create a Box class that will be exactly the same as the Ball class, except in the draw method, we will draw a rect.
- Create multiple boxes and have them move/bounce around
