dijkstra_path¶

dijkstra_path
(G, source, target, weight='weight')[source]¶ Returns the shortest path from source to target in a weighted graph G.
Parameters:  G (NetworkX graph) –
 source (node) – Starting node
 target (node) – Ending node
 weight (string, optional (default=’weight’)) – Edge data key corresponding to the edge weight
Returns: path – List of nodes in a shortest path.
Return type: Raises: NetworkXNoPath
– If no path exists between source and target.Examples
>>> G=nx.path_graph(5) >>> print(nx.dijkstra_path(G,0,4)) [0, 1, 2, 3, 4]
Edge weight attributes must be numerical. Distances are calculated as sums of weighted edges traversed.
