neighbors¶
-
Graph.
neighbors
(n)[source]¶ Return an iterator over all neighbors of node n.
Parameters: n (node) – A node in the graph Returns: neighbors – An iterator over all neighbors of node n Return type: iterator Raises: NetworkXError
– If the node n is not in the graph.Examples
>>> G = nx.path_graph(4) # or DiGraph, MultiGraph, MultiDiGraph, etc >>> [n for n in G.neighbors(0)] [1]
Notes
It is usually more convenient (and faster) to access the adjacency dictionary as
G[n]
:>>> G = nx.Graph() # or DiGraph, MultiGraph, MultiDiGraph, etc >>> G.add_edge('a', 'b', weight=7) >>> G['a'] {'b': {'weight': 7}} >>> G = nx.path_graph(4) >>> [n for n in G[0]] [1]
