degree

MultiDiGraph.degree(nbunch=None, weight=None)

Return the degree of a node or nodes.

The node degree is the number of edges adjacent to that node.

Parameters:
  • nbunch (iterable container, optional (default=all nodes)) – A container of nodes. The container will be iterated through once.
  • 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:

nd – A dictionary with nodes as keys and degree as values or a number if a single node is specified.

Return type:

dictionary, or number

Examples

>>> G = nx.Graph()   # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> G.add_path([0,1,2,3])
>>> G.degree(0)
1
>>> G.degree([0,1])
{0: 1, 1: 2}
>>> list(G.degree([0,1]).values())
[1, 2]
