are_neighbors(G, v, nbunch)¶
Returns true if v is adjacent to any of the nodes in nbunch. Otherwise, returns false.
- G (NetworkX graph) – An undirected graph.
- v (node) – A node in the graph.
- nbunch – A single node or iterable container
If nbunch in a single node, True if v in a neighbor that node and False otherwise.
If nbunch is an interable, True if v is a neighbor of some node in nbunch and False otherwise.
