An idea I had to code comparisons... The idea is that you can't "have" a comparison without two things to compare, a, b... so it could go in a constructor. This could also be useful as a template method pattern.

Comparison.py

class Comparison:
    def __init__(self, a, b, **kwargs):
        self.a = a
        self.b = b
        self.kwargs = kwargs

    def compare(self):
        """ .compare() -> Union[1, -1, 0]"""
        if self._a_has_higher_precedence():
          return 1
        if self._a_has_equal_precedence():
          return 0
        if self._a_has_lower_precedence():
          return -1
        return 0. # or raise?

    def _a_has_higher_precedence(self):
        pass

    def _a_has_lower_precedence(self):
        pass

    def _a_has_equal_precedence(self):
        pass
