:) It's many years since I played with the C64, and I certainly
don't remember the addresses. Don't even know where the manuals
are right now... But Python is not a machine. Python runs on many
different types of computers, from palm tops to main frames. They
don't have a lot in common regarding graphics hardware.

There is no native way to manipulate memory or hardware registers
directly from Python.

It was simpler in those days, but I can't say I want it back. I
remember how hard it was to read the letters on the screen when
you tried to squeeze 64 character into a line...

Somewhere around here I lost you. I don't have the faintest idea
what this and the reast has to do with this email thread...

It's a bit confusing how the underlying code in the GUI tool kits
hold "invisible" references to things. I usually keep explicit
references in my programs anyway, after all, you often want to do
things with your widgets from the program...
