I don't think it's very helpful to anyone to say that "everything is an object", because "everything" is far too vague a term. (It's not even close to being true -- there are plenty of concepts in Python that are not objects.)
I think I would say something like "All data that a Python program can manipulate comes in the form of things we call objects." Then go on to give some examples of different kinds of objects -- integer objects, string objects, list objects, etc. And that variables in Python don't contain objects, they just refer to objects. Draw some diagrams with boxes and arrows. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
