all_pairs_shortest_path#
- all_pairs_shortest_path(G, cutoff=None)[source]#
Compute shortest paths between all nodes.
- Parameters:
- GNetworkX graph
- cutoffinteger, optional
Depth at which to stop the search. Only paths of length at most
cutoff
are returned.
- Returns:
- pathsiterator
Dictionary, keyed by source and target, of shortest paths.

Notes
There may be multiple shortest paths with the same length between two nodes. For each pair, this function returns only one of those paths.
Examples
>>> G = nx.path_graph(5) >>> path = dict(nx.all_pairs_shortest_path(G)) >>> print(path[0][4]) [0, 1, 2, 3, 4]
