networkx.single_source_shortest_path

single_source_shortest_path(G, source, cutoff=None)

Return list of nodes in a shortest path between source and all other nodes reachable from source.

There may be more than one shortest path between the source and target nodes - this routine returns only one.

Returns a dictionary of shortest path lengths keyed by target.

Parameters:

G : NetworkX graph

source : node label

starting node for path

cutoff : integer, optional

depth to stop the search - only paths of length <= cutoff are returned.
