networkx.MultiDiGraph.size¶

MultiDiGraph.
size
(weight=None)¶ Returns the number of edges or total of all edge weights.
Parameters: weight (string or None, optional (default=None)) – The edge attribute that holds the numerical value used as a weight. If None, then each edge has weight 1. Returns: size – The number of edges or (if weight keyword is provided) the total weight sum. If weight is None, returns an int. Otherwise a float (or more general numeric if the weights are more general).
Return type: numeric See also
Examples
>>> G = nx.path_graph(4) # or DiGraph, MultiGraph, MultiDiGraph, etc >>> G.size() 3
>>> G = nx.Graph() # or DiGraph, MultiGraph, MultiDiGraph, etc >>> G.add_edge('a', 'b', weight=2) >>> G.add_edge('b', 'c', weight=4) >>> G.size() 2 >>> G.size(weight='weight') 6.0
