I propose adding the ability to compare range objects using methods (e.g. range.issubrange) and/or regular operators. Example:In [56]: range(0, 10, 3).issubrange(range(10))Out[56]: TrueIn [57]: range(0, 10, 3) <= range(10)Out[57]: TrueIn [58]: range(10) <= range(0, 10, 3)Out[58]: FalseI'll write a patch if you decide that this idea is worth implementing.
