I think pari/gp can do arithmetic over general Galois fields. I
certainly have a recollection of doing that with it in the past. Its
free (GPL) too, and has a library that could be wrapped with SWIG/etc
to make it python friendly.
* PARI is a C library, allowing fast computations.
* gp is an interactive shell giving access to PARI functions, much easier to use.
* GP is the name of gp' s scripting language
* gp2c the GP-to-C compiler makes the best of both worlds
If someone did wrap PARI in python it would certainly be easier to use
than GP which I found very unintuitive!
In fact I just found this which looks like just the job!
