Python does not have variables in the sense you are using it here (the
'C' sense).  The closest are slot in a list.

No, No, No!  Not in Python.

In C, a name represents a fixed block of linear memory with an address
and size.
'a = expression' puts the value of the expression into that block.
(Which raises concerns, nonexistent in Python, about size/type
mismatch.)

In Python, a name is just a name -- period -- with no connection to
'memory'.
'a = expression' assigns the name to an object with the value of the
expression by associating the name with a reference to that object in
a namespace (which may or may not be a dictionary).  Any name can be
bound to any object at any time.  Note that assignment is, in a sense,
from left to right rather than from right to left as in most
languages.
