path_weight(G, path, weight)

Parameters

G : graph

A NetworkX graph.

path: list :

A list of node labels which defines the path to traverse

weight: string :

A string indicating which edge attribute to use for path cost

Raises

NetworkXNoPath

If the specified edge does not exist.

Returns

cost: int or float

An integer or a float representing the total cost with respect to the specified weight of the specified path

Returns total cost associated with specified path and weight

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
