Examples
>>> idx1 = ps.Index([2, 1, 3, 4]) >>> idx2 = ps.Index([3, 4, 5, 6]) >>> 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)], )
