disjoint_union(G, H)[source]¶ Return the disjoint union of graphs G and H.
This algorithm forces distinct integer node labels.
- Parameters
G,H (graph) – A NetworkX graph
- Returns
U
- Return type
A union graph with the same type as G.
Notes
A new graph is created, of the same class as G. It is recommended that G and H be either both directed or both undirected.
The nodes of G are relabeled 0 to len(G)-1, and the nodes of H are relabeled len(G) to len(G)+len(H)-1.
Graph, edge, and node attributes are propagated from G and H to the union graph. If a graph attribute is present in both G and H the value from H is used.
