Examples
Index
>>> idx1 = ps.Index([1, 2, 3, 4]) >>> idx2 = ps.Index([3, 4, 5, 6]) >>> idx1.union(idx2).sort_values() Int64Index([1, 2, 3, 4, 5, 6], dtype='int64')
MultiIndex
>>> midx1 = ps.MultiIndex.from_tuples([("x", "a"), ("x", "b"), ("x", "c"), ("x", "d")]) >>> midx2 = ps.MultiIndex.from_tuples([("x", "c"), ("x", "d"), ("x", "e"), ("x", "f")]) >>> midx1.union(midx2).sort_values() MultiIndex([('x', 'a'), ('x', 'b'), ('x', 'c'), ('x', 'd'), ('x', 'e'), ('x', 'f')], )
