Playing around with python's rich comparison operators

rich_comparisons.py

from __future__ import print_function
import functools

@functools.total_ordering
class Comparable():
    def __init__(self, value):
        self._value = value

    def __lt__(self, o):
        return self._value < o._value

    def __eq__(self, o):
        return self._value == o._value

    #<<< def __cmp__(self, o):
    #<<<     return self._value - o._value

    def __repr__(self):
        return "{}".format(self._value)

one = Comparable(1)
two = Comparable(2)
other_one = Comparable(1)

def every_operator(val1, val2):
    print("{} == {}: {}".format(val1, val2, val1 == val2))
    print("{} < {}: {}".format(val1, val2, val1 < val2))
    print("{} <= {}: {}".format(val1, val2, val1 <= val2))
    print("{} > {}: {}".format(val1, val2, val1 > val2))
    print("{} >= {}: {}".format(val1, val2, val1 >= val2))

every_operator(one, one)
print()
every_operator(one, two)

I was toying around with this after reading http://portingguide.readthedocs.io/en/latest/comparisons.html.
