degree_iter¶

DiGraph.degree_iter(nbunch=None, weight=None)[source]¶

Return an iterator for (node, degree).

The node degree is the number of edges adjacent to the 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_iter – The iterator returns two-tuples of (node, degree).
Return type:	an iterator

Examples

>>> G = nx.DiGraph()   # or MultiDiGraph
>>> G.add_path([0,1,2,3])
>>> list(G.degree_iter(0)) # node 0 with degree 1
[(0, 1)]
>>> list(G.degree_iter([0,1]))
[(0, 1), (1, 2)]
