Why not simply use a list v with elements v_1,v_2,...,v_n? So input (Q, [v_1,v_2,v_3]) into a function sage: def(Q, v): ....: # start by unpacking the elements of v ....: Mike's example would become sage: def f(v): ....: return sum(v) ....: sage: f([1,2,3]) 6 sage: f([2,3,5,8]) 18 -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
