out_degree_iter

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

Return an iterator for (node, out-degree).

The node out-degree is the number of edges pointing out of 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 : an iterator

The iterator returns two-tuples of (node, out-degree).

Examples

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