difference(G, H)[source]

Returns a new graph that contains the edges that exist in G but not in H.

The node sets of H and G must be the same.


A NetworkX graph. G and H must have the same node sets.

DA new graph with the same type as G.


Attributes from the graph, nodes, and edges are not copied to the new graph. If you want a new graph of the difference 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 in H)
