>>> idx1.difference(idx2, sort=True)
Int64Index([1, 2], dtype='int64')

MultiIndex

>>> midx1 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'y', 2), ('c', 'z', 3)])
>>> midx2 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'z', 2), ('k', 'z', 3)])
>>> midx1.difference(midx2)  
MultiIndex([('b', 'y', 2),
            ('c', 'z', 3)],
           )
