(G, u, v)[source]¶ Return the common neighbors of two nodes in a graph.
Parameters:  G (graph) – A NetworkX undirected graph.
 v (u,) – Nodes in the graph.
Returns: cnbors – Iterator of common neighbors of u and v in the graph.
Return type: iterator
Raises: NetworkXError
– If u or v is not a node in the graph.Examples
>>> G = nx.complete_graph(5) >>> sorted(nx.common_neighbors(G, 0, 1)) [2, 3, 4]
