networkx.DiGraph.edge_subgraph¶

DiGraph.
edge_subgraph
(edges)¶ Returns the subgraph induced by the specified edges.
The induced subgraph contains each edge in
edges
and each node incident to any one of those edges.Parameters: edges (iterable) – An iterable of edges in this graph. Returns: G – An edgeinduced subgraph of this graph with the same edge attributes. Return type: Graph Notes
The graph, edge, and node attributes in the returned subgraph view are references to the corresponding attributes in the original graph. The view is readonly.
To create a full graph version of the subgraph with its own copy of the edge or node attributes, use:
>>> G.edge_subgraph(edges).copy()
Examples
>>> G = nx.path_graph(5) >>> H = G.edge_subgraph([(0, 1), (3, 4)]) >>> list(H.nodes) [0, 1, 3, 4] >>> list(H.edges) [(0, 1), (3, 4)]
