Graph.neighbors#

Graph.neighbors(n)[source]#

Returns an iterator over all neighbors of node n.

This is identical to iter(G[n])

Parameters:
nnode

A node in the graph

Returns:
neighborsiterator

An iterator over all neighbors of node n

Raises:
NetworkXError

If the node n is not in the graph.

Notes

Alternate ways to access the neighbors are G.adj[n] or G[n]:

>>> G = nx.Graph()  # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> G.add_edge("a", "b", weight=7)
>>> G["a"]
AtlasView({'b': {'weight': 7}})
>>> G = nx.path_graph(4)
>>> [n for n in G[0]]
[1]

Examples

>>> G = nx.path_graph(4)  # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> [n for n in G.neighbors(0)]
[1]
