Hello,
I am not sure this is what you want
sage: var('x,y')
(x, y)
sage: expr = x + y^2

thank you. actually i mean in gap system
i solved with
poly1 := 0;
for j in [1..Length(prepoly1[1])] do
zz:=1;
for i in SplitString(String(prepoly1[1][j]), + ) do
zz:=zz*EvalString(i);
od;
if zz 1 then
poly1 := poly1 + zz;
fi;
od;
