Some years ago I wrote code to do some simple arithmetic in polynomials and
finite fields for a class on Python which I taught. As far as I remember,
you could combine these as well. It's not very sophisticated and probably
not state of the art regarding current Python features, but I think it
should still work. If you're interested, I could dig out the code for you.

I'd be curious as well as to whether there is some more advanced and
actively maintained package around for these things.

Cheers,
Olaf
