Please excuse a stupid question of someone who doesn't use symbolic functions or symbolic variables (I rather work with polynomials). Why should one want to turn a Python function (or method) into a symbolic function? I guess one couldn't do calculus (differentiate, integrate) the resulting symbolic function, or can one? So, beyond calculus, what can one do with a symbolic function that can't be done with a Python function?
