MultiGraph.add_weighted_edges_from(ebunch, weight='weight', **attr)

Add all the edges in ebunch as weighted edges with specified weights.

Parameters :

ebunch : container of edges

Each edge given in the list or container will be added to the graph. The edges must be given as 3-tuples (u,v,w) where w is a number.

weight : string, optional (default= ‘weight’)

The attribute name for the edge weights to be added.

attr : keyword arguments, optional (default= no attributes)

Edge attributes to add/update for all edges.

Notes

Adding the same edge twice for Graph/DiGraph simply updates the edge data. For MultiGraph/MultiDiGraph, duplicate edges are stored.

Examples

>>> G = nx.Graph()   # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> G.add_weighted_edges_from([(0,1,3.0),(1,2,7.5)])
