- DiGraph.in_degree_iter(nbunch=None, weight=None)¶
Return an iterator for (node, in-degree).
The node in-degree is the number of edges pointing in to the node.
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.
nd_iter : an iterator
The iterator returns two-tuples of (node, in-degree).
>>> G = nx.DiGraph() >>> G.add_path([0,1,2,3]) >>> list(G.in_degree_iter(0)) # node 0 with degree 0 [(0, 0)] >>> list(G.in_degree_iter([0,1])) [(0, 0), (1, 1)]
