Hi there,
when I have a python class X which overloads an operator, I can use that
operator to do any operation for example with an integer
y = X() + 123
however, say I want the "+" operator to be commutative. Then
y = 123 + X()
should have the same result. However, since it does not call __ad

Incidentally - this isn't really about commutativity at all - the
question is how can you define both left and right versions of add,
irrespective of whether they yield the same result.
I think __radd__ is what you're after.
