Can you explain a little more about what does not work? When I try to replicate your example, everything works as expected:
sage: n=2 ....: F = GF(7) ....: Rx=PolynomialRing(F,n,'x') ....: X=Rx.gens() sage: f=X[0]+X[1] sage: f(x0=1) x1 + 1 sage: f(x0=1,x1=1) 2 Alternatively you can evaluate using positional arguments: in a polynomial ring there is a clear implied order on the generators, so the following is unambiguous (and accepted): sage: f(1,1) #gives values for x0 and x1 in order 2 On Friday, 29 April 2022 at 04:33:36 UTC-7 Ha wrote: > Hi, > I need to create a polynomial ring with arbitrary number of variables [n] > and > at some point during computation should be able to substitute values > for a subset of variables.
