The purpose of a car is not to learn how to ride a bicycle. Yes, I am
thinking in terms of an ultimate goal, because the point of coding is
to achieve something. Maybe your goal *right now* is to learn rather
than to create, but surely the purpose of the learning is to be able
to achieve things later?

Rather than try to implement pass-by-reference semantics in Python,
figure out what abstract concept you're actually trying to implement.
Otherwise, all you'll do is come up with convoluted methods of
implementing some other language's semantics in Python, and then write
your code using that other language's idioms, and run it in a Python
interpreter. Far better to actually learn Python's semantics, and how
they can be used to represent your actual goals.
