Hello!

I am trying to work with the curve constructor (particularly affine curves) in sage using their built in functions. I am using this page as reference: https://doc.sagemath.org/html/en/reference/curves/sage/schemes/curves/affine_curve.html

But when I try to define curves like below I get the list object not callable error message every time, even when I copy and paste code from the sage reference manual.

A.<x,y> = AffineSpace(QQ, 2)

C = Curve(x^2 + y^2 -1)

I understand that it probably thinks Curve is a list or something, but I'm not sure how to fix it?

Any help would be greatly appreciated!
