Note that we don't define __hash__: not all sets are hashable. But if you define a hashable set type, its __hash__ should call this function. This must be compatible __eq__. All sets ought to compare equal if they contain the same elements, regardless of how they are implemented, and regardless of the order of the elements; so there's not much freedom for __eq__ or __hash__. We match the algorithm used by the built-in frozenset type. � � iM��r� i�M[l �4~2 i� i��6i��8#���)�sys�maxsizer5 �hash)r �MAX�MASK�n�hr/ �hxr r r �_hash s z Set._hashN)r" r# r$ �__doc__r% r8 r9 r; r: r< r& r> r@ �__rand__rA rE �__ror__rF rG rH �__rxor__rU r r r r r � s$ c @ s� e Z d Z d Z f Z e d d � � Z e d d � � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d d � Z d S)r a� A mutable set is a finite, iterable container.
