sage: p=2
sage: F4=GF(p^4)
sage: R.<x,y,z>=PolynomialRing(F4)
sage: C=Curve(y^3-z*x^2-z^2*x)
sage: len(C.rational_points())
9
sage: L=C.L_polynomial()

I get

AttributeError: 'ProjectivePlaneCurve_finite_field_with_category' object has no attribute 'L_polynomial'

Well, it is what is it - your C object does not have L_polynomial method defined. Why do you expect it to work?

It seems that, in Sage, only global function fields have an L_polynomial method.
