What methods need to be overridden/implemented when making user-defined classes sortable and/or hashable in python?
What are the gotchas to watch out for?
I type dir({})
into my interpreter to get a list of methods on built-in dicts. Of those, I assume I need to some implement some subset of
['__cmp__', '__eq__', '__ge__', '__gt__', '__hash__', '__le__', '__lt__', '__ne__']
Is there a difference in which methods must be implemented for Python3 as opposed to Python2?
