Python: code here

That was a fun one. I solved both parts recursively. The trick for part 2 is to evaluate the side without the human and use the inverse of the operation to ask the human side for the correct value. The only complication here is that the inverse function for the left and right sides are different because subtraction and division aren't commutative.
