Somewhere along the line (in the original thread) the idea of
trying to teach a Beginner how to design an OOP in "Python"
got lost in a bunch of java mumbo jumbo (at least, that's
what it seemed like to me).

After looking at a lot of stuff, and reading much more than
I needed to, the technique that works best for me is the
noun/verb technique. I think it is a good STARTING point!

Now, I understand that there are many different levels of
"beginner". Some beginners are higher up the ladder than
others, and they enjoy looking in windows higher up. However,
I'm still on the bottom rung. The technique that I can relate to
is the noun/verb technique. Does this mean that if I get a grasp
of POOP with this technique that I'll be stuck on the bottom
rung forever? I doubt it. No more than someone who is using
whatever technique they are currently using is stuck with that
technique forever.

The universe unfolds perfectly.
Time exists so it doesn't unfold all at once.

I think the noun/verb technique is good for Absolute beginners.
I haven't seen anything else that is so introductory.

Too bad there isn't a graded tutorial that systematically
uses the technique to build several working PYTHON OOPs.

Happy Programming!
