dynetworkx.IntervalGraph.degree

IntervalGraph.degree(node=None, begin=None, end=None, delta=False)

Return the degree of a specified node between time begin and end.

Parameters:

• node (Nodes can be, for example, strings or numbers, optional.) – Nodes must be hashable (and not None) Python objects.
• begin (int or float, optional (default= beginning of the entire interval graph)) – Inclusive beginning time of the edge appearing in the interval graph.
• end (int or float, optional (default= end of the entire interval graph)) – Non-inclusive ending time of the edge appearing in the interval graph.

Returns:

• Integer value of degree of specified node.
• If no node is specified, returns float mean degree value of graph.
• If delta is True, return list of tuples. – First indicating the time a degree change occurred, Second indicating the degree after the change occured

Examples

>>> G = IntervalGraph()
>>> G.add_edge(1, 2, 3, 5)
>>> G.add_edge(2, 3, 8, 11)
>>> G.degree(2)
2
>>> G.degree(2,2)
2
>>> G.degree(2,end=8)
1
>>> G.degree()
1.33333
>>> G.degree(2,delta=True)
[(3, 1), (5, 0), (8, 1)]
