single_target_shortest_path(G, target, cutoff=None)¶
Compute shortest path to target from all nodes that reach target.
G (NetworkX graph)
target (node label) – Target node for path
cutoff (integer, optional) – Depth to stop the search. Only paths of length <= cutoff are returned.
lengths – Dictionary, keyed by target, of shortest paths.
- Return type
>>> G = nx.path_graph(5, create_using=nx.DiGraph()) >>> path = nx.single_target_shortest_path(G, 4) >>> path [0, 1, 2, 3, 4]
The shortest path is not necessarily unique. So there can be multiple paths between the source and each target node, all of which have the same ‘shortest’ length. For each target node, this function returns only one of those paths.
