dynetx.classes.function.number_of_interactions

dynetx.classes.function.number_of_interactions(G, u=None, v=None, t=None)

Return the number of edges between two nodes at time t.

Parameters

G : a dynetx graph object u : node, optional (default=all edges) v : node, optional (default=all edges) t : snapshot id (default=None)

If None will be returned the number of edges on the flattened graph.

If u and v are specified, return the number of edges between u and v. Otherwise return the total number of all edges.

Returns

nedgesint

The number of edges in the graph. If nodes u and v are specified return the number of edges between those nodes.

Examples

>>> import dynetx as dn
>>> G = dn.DynGraph()
>>> G.add_path([0,1,2,3], t=0)
>>> dn.number_of_interactions(G, t=0)
