Hello, I'm trying to parse symbolic expressions, but got stuck very quickly.
If I say: (x^2).operator() I get: <built-in function pow> If I say: pow I also get: <built-in function pow> But if I say: (x^2).operator()==pow I get: False How do I properly test if the topmost operation of an expression is a power, product, sum, whatever?
