No python is correct. you're expression parses this way, when converted to a lisp-ish prefix expression: (- (123 ** 0 )) All calculators work this way, so I don't know why you are expecting anything otherwise. > > The problem is that Python parses -123**0 as -(123**0), not as > (-123)**0. > > I suggest making the Python parser omit the negative sign if a > negative number is raised to the power of 0.
