3.5.4.9. networkx.MultiDiGraph.out_degree

MultiDiGraph.out_degree(nbunch=None, weight=None)[source]

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

The node out-degree is the number of edges pointing out of the node. This function returns the out-degree for a single node or an iterator for a bunch of nodes or if nothing is passed as argument.

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.
Returns:

If a single node is requested

deg : int

Degree of the node

OR if multiple nodes are requested

nd_iter : iterator

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

Examples

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