Hi, given a list of variable names as strings (e.g., l =
['a','b','c','d']) I try to make those become variables in a
Polynomial Ring. One way is to do something like
R.a,b,c,d=CC['a','b','c','d'] , after this the type of a or b or c

Hi John and Jason, thanks -- the inject_variables() did what I
want.
I have another question below and hope you can help
what if I already have create a function call f = x - y as below
sage: vs = var('x y')
sage: f = x - y
sage: type(f)
type 'sage.symbolic.expression.Expression'
now I

ah thanks much -- I also just found it by just trial and error.

There's still one type error about parent mismatch in my code.
Basically I want to write a function foo like below
def foo(f1,f2,vs):
R = PolynomialRing(QQ,vs)
f1_ = f1.polynomial(QQ)
f2_ = f2.polynomial(QQ)
I = R*[f1_]
G = I.radical().groebner_basis()
res =

Nils, thanks -- I think I was able to do what I want using your code
snippet
def foo(f1,f2,vs):
R = PolynomialRing(QQ,vs)
f1_ = R(f1)
f2_ = R(f2)
I = R*[f1_]
G = I.radical().groebner_basis()
res = f2_.reduce(G)
return res == 0
