Hello,
How would one find the list of variables in a monomial?
For example,
(p^2 * q^3).exponents()
returns
[(2,3)]
(without using a ring).
Is there a command that will return something like [(p,q)] or [(p,2),
(q,3)]?

What I've put together is about the same size as what you are talking
about. I do remember seeing something in one of the distributions I
got that did not work. What I've written should work as long as it is
in the same directory as the sage executable file. It does not care

True, we fixed this in SPD because it is a problem there, however, I

I think if the docstrings were sufficiently expanded then it should
