single_source_shortest_path(G, source, cutoff=None)¶
Compute shortest path between source and all other nodes reachable from source.
- GNetworkX graph
- sourcenode label
Starting node for path
- cutoffinteger, optional
Depth to stop the search. Only paths of length <= cutoff are returned.
Dictionary, keyed by target, of shortest paths.
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.
>>> G = nx.path_graph(5) >>> path = nx.single_source_shortest_path(G, 0) >>> path [0, 1, 2, 3, 4]
