Examples
>>> import cudf >>> idx1 = cudf.Index([2, 1, 3, 4]) >>> idx1 Index([2, 1, 3, 4], dtype='int64') >>> idx2 = cudf.Index([3, 4, 5, 6]) >>> idx2 Index([3, 4, 5, 6], dtype='int64') >>> idx1.difference(idx2) Index([1, 2], dtype='int64') >>> idx1.difference(idx2, sort=False) Index([2, 1], dtype='int64')
