WebMultiGraph. add_weighted_edges_from (ebunch_to_add, weight = 'weight', ** attr) # Add weighted edges in ebunch_to_add with specified weight attr. Parameters: ebunch_to_add 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. WebIn graph theory, a multigraph (or pseudograph ) is a graph in which the presence of multiple edges is allowed [en] (they are also called “parallel” [1] ), that is, edges that have the same finite vertices. Thus, two vertices can be connected by more than one edge.
