programming class

A class is a machine for creating objects

Object oriented programming (OOP) languages (like Python) let you create
an entirely new kind of object using a class. A class is like a template that you
use to create new objects.
Think of the class like a cookie-cutter, and think of the object as the cookie
that is created based on the class. As all the cookies are created from the same
cookie cutter, they all have the same characteristics, even though they are
all individual cookies. When an individual object is created from a class, it’s
referred to as an instance of that class.

So, if you can arrange for SoundPanel() to be a class, you can create
custom widgets as required:

You need a new
SoundPanel() class.

SoundPanel

The CLASS creates OBJECTs, which
are INSTANCEs of the class.

You need code that creates a new grouped widget in the GUI every time you
make a call like this:
Use the class to create a new object.

panel = SoundPanel(app, mixer, "49119_M_RED_HardBouncer.wav")

Let’s define a SoundPanel() class.
