- intersection(G, H)#
Returns a new graph that contains only the nodes and the edges that exist in both G and H.
A NetworkX graph. G and H can have different node sets but must be both graphs or both multigraphs.
- GHA new graph with the same type as G.
If one is a MultiGraph and the other one is a graph.
Attributes from the graph, nodes, and edges are not copied to the new graph. If you want a new graph of the intersection of G and H with the attributes (including edge data) from G use remove_nodes_from() as follows
>>> G = nx.path_graph(3) >>> H = nx.path_graph(5) >>> R = G.copy() >>> R.remove_nodes_from(n for n in G if n not in H) >>> R.remove_edges_from(e for e in G.edges if e not in H.edges)
>>> G = nx.Graph([(0, 1), (0, 2), (1, 2)]) >>> H = nx.Graph([(0, 3), (1, 2), (2, 3)]) >>> R = nx.intersection(G, H) >>> R.nodes NodeView((0, 1, 2)) >>> R.edges EdgeView([(1, 2)])
