Let's reword a bit better.  Objects are objects and *not* references.
Variables are names associated with objects via internal references.

You mean like

a = ['test']
b = a
b[0] = 'done'
print a

?
This prints 'done', but this scheme only works with mutable objects.

PS.  CPython uses the id of an object as its internal reference, but
when you retrieve the id with the id() function, it becomes an
external int object and useless for accessing the object (unless you
subvert the interpreter by writing a custom C extension to do so).
