Hi Phil,
I don't think there is an official way to get at the terms, but here
is something that works:
sage: var('x,y')
(x, y)
sage: t = x^2 + y^2
sage: type(t)
<class 'sage.calculus.calculus.SymbolicArithmetic'>
sage: t._operator
<built-in function add>
sage: t._operands
[x^2, y^2]
sage: t._operands[0]
x^2
