No.

You can overload certain methods to make an object behave like one
of its attributes in certain contexts (e.g. comparisions, math operations,
conversions), but you cannot do it for all operations.

Especially not the "assignment operator", since there is no such thing in
Python.  (assignment is a statement, and it's an operation on the target
namespace, not the source object).

(As always, Python works better if you use it to write Python programs)
