MultiDiGraph.out_degree#

property MultiDiGraph.out_degree#

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

out_degree(self, nbunch=None, weight=None)

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:

nbunchsingle node, container, or all nodes (default= all nodes): The view will only report edges incident to these nodes.
weightstring 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
degint: Degree of the node
OR if multiple nodes are requested
nd_iteriterator: 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, 2]))
[(0, 1), (1, 1), (2, 1)]
>>> G.add_edge(0, 1)  # parallel edge
1
>>> list(G.out_degree([0, 1, 2]))  # counts parallel edges
[(0, 2), (1, 1), (2, 1)]
