degrees

degrees(B, nodes, weight=None)[source]

Return the degrees of the two node sets in the bipartite graph B.

Parameters:

G : NetworkX graph

nodes: list or container

Nodes in one set of the bipartite graph.

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. The degree is the sum of the edge weights adjacent to the node.

Returns:

(degX,degY) : tuple of dictionaries

The degrees of the two bipartite sets as dictionaries keyed by node.

>>> from networkx.algorithms import bipartite
>>> G = nx.complete_bipartite_graph(3,2)
>>> Y=set([3,4])
>>> degX,degY=bipartite.degrees(G,Y)
>>> degX
