symmetric_difference

symmetric_difference(G, H)

Returns new graph with edges that exist in either G or H but not both.

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

Parameters

G,Hgraph

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

Returns

DA new graph with the same type as G.

Notes

Attributes from the graph, nodes, and edges are not copied to the new graph.

Examples

>>> G = nx.Graph([(0, 1), (0, 2), (1, 2), (1, 3)])
>>> H = nx.Graph([(0, 1), (1, 2), (0, 3)])
>>> R = nx.symmetric_difference(G, H)
>>> R.nodes
NodeView((0, 1, 2, 3))
>>> R.edges
EdgeView([(0, 2), (0, 3), (1, 3)])
