DiGraph.
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.

add_edge
- add a single edge
add_edges_from
- add multiple 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)])
