how to factorize an expression with constant variables ?

Hello, I would like to factorize an expression with sage that contains constant variables (i.e. parameters), but I cannot figure out how to do that.

Here is an example : x, y are variables and A is a parameter


var('A x y')

f = Ax + x + A^2exp(y) + y print (f.factor())


Sage returns 'A^2e^y + Ax + x + y'. Instead, I would like that sage returns '(A+1)x + (A^2+1)exp(y)'.

How to do that ? Thank you

(f.factor())

Sage returns 'A^2e^y A^2*e^y + Ax A*x + x + y'. y. Instead, I would like that sage returns '(A+1)x (A+1)*x + (A^2+1)exp(y)'.(A^2+1)*exp(y).
