Maybe this is better since it includes the arithmetic operators:

(1) -> pureForm(p)==reduce(*,[(i.factor^i.exponent)::InputForm for i in factorsp])::InputForm
                                  Type: Void

(2) -> p:=factor((x+y)*(x^2))

         2
   (2)  x (y + x)
                                  Type: Factored Polynomial Integer

(3) -> pureForm p
   Compiling function pureForm with type Factored Polynomial Integer
       -> InputForm

   (3)  (* (** x 2) (+ y x))
                                   Type: InputForm
