number_of_edges¶

Graph.
number_of_edges
(u=None, v=None)[source]¶ Return the number of edges between two nodes.
Parameters: v (u,) – If u and v are specified, return the number of edges between u and v. Otherwise return the total number of all edges. Returns: nedges – The number of edges in the graph. If nodes u and v are specified return the number of edges between those nodes. Return type: int See also
Examples
>>> G = nx.Graph() # or DiGraph, MultiGraph, MultiDiGraph, etc >>> G.add_path([0,1,2,3]) >>> G.number_of_edges() 3 >>> G.number_of_edges(0,1) 1 >>> e = (0,1) >>> G.number_of_edges(*e) 1
