No, I'm not. I'm talking about pointers in the abstract sense, both in
case of Python and Pascal. Neither language gives any hint as to the
physical nature of the pointer.

All Python expressions evaluate to pointers (or handles or references;
call them whatever you want). All Python "lvalues" hold pointers.
