So basically, OO is the principles:
polymorph,
encaps,
inheritance.

And Programming by extension is the way to do it in Ada, as
class something:
{
}
would be in C++?


One thing I'm still confused on is the use of access objects
versus/with the use of object'class.
I understand using object'class for polymorphism and inheritance, but
can access objects be used in a similar manner?


As for the use of the python program.  It was just something I wrote a
week ago for a group I help with.  Since it was still fresh in my head,
it was the easiest thing to try to convert.
