maxima allows to collect multiple terms, so it is possible to do so in Sage using:

sage: f = 4*x*y + x*z + 20*y^2 + 21*y*z + 4*z^2 + x^2*y^2*z^2
sage: fm = f.maxima_methods()
sage: fm.collectterms(x,y)
x^2*y^2*z^2 + 4*x*y + x*z + 20*y^2 + 21*y*z + 4*z^2
sage: fm.collectterms(x)
x^2*y^2*z^2 + (4*y + z)*x + 20*y^2 + 21*y*z + 4*z^2


is this what yo need?

x^2*y^2*z^2 + (4*y + z)*x + 20*y^2 + 21*y*z + 4*z^2


is from there you could use the operands() method to simplify each term separately. Is this what yo need?enough?

Can you assume that your expression is polynomial in x and y?
