sage: preparse("f(x)=1") '__tmp__=var("x"); f = symbolic_expression(Integer(1)).function(x) On the plus side, we have very concise syntax for defining symbolic variables without having to write quotes: sage: _(x,y,z)=1 sage: x^2+y^2+z^2 x^2 + y^2 + z^2 which is shorter than var("x,y,z") AND it doesn't cause a tuple to be printed. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
