If you're doing a dictionary anyway, doesn't it make more sense to use **kwargs? For example,
sage: P.<x,y>=ZZ[] sage: f=x*y^2+x*y+y+x+1 sage: f.coefficient(y=2) x sage: f.coefficient(y=1) x + 1 sage: f.coefficient(x=1, y=2) 1 It takes a little bit to get used to the semantics of it, but the syntax is much more natural / Pythonic. --Mike On 10/12/07, didier deshommes <[EMAIL PROTECTED]> wrote: > > 2007/10/12, Joel B.
