grinpy.functions.neighborhoods.are_neighbors(G, u, v)¶

Returns true if u is adjacent to v. Otherwise, returns false.

Parameters:	G (NetworkX graph) – An undirected graph. u (node) – A node in the graph. v (node) – A node in the graph.
Returns:	True if u is a neighbor of v in G, False otherwise.
Return type:	bool

Examples

>>> G = nx.star_graph(3) # Star on 4 nodes
>>> nx.are_neighbors(G, 0, 1)
True
>>> nx.are_neighbors(G, 1, 2)
False
