File imports for polynomial rings in sage
If i type in the following
R.<z1,z2> = PolynomialRing(GF(5),2,"z")
direclty to Sage it accepts it as a polynomial ring.
But if i place this in a .py file and load it from this Sage
sage my.py it gives me a syntax error.
I guess i need a module loaded for it to be detected, but which module and hence which command do i need to make Sage accept this ring.
