dynetx.DynDiGraph.in_interactions

DynDiGraph.in_interactions(nbunch=None, t=None)

Return the list of incoming interaction present in a given snapshot.

Edges are returned as tuples in the order (node, neighbor).

Parameters

nbunchiterable container, optional (default= all nodes)

A container of nodes. The container will be iterated through once.

tsnapshot id (default=None)

If None the the method returns all the edges of the flattened graph.

Returns

interaction_list: list of interaction tuples

Interactions that are adjacent to any node in nbunch, or a list of all interactions if nbunch is not specified.

Notes

Nodes in nbunch that are not in the graph will be (quietly) ignored. For directed graphs this returns the out-interaction.

Examples

>>> import dynetx as dn
>>> G = dn.DynDiGraph()
>>> G.add_interaction(0, 1, t=0)
>>> G.add_interaction(2, 3, t=1)
>>> G.in_interactions(t=0)
[(1, 0)]
>>> G.in_interactions()
[(1, 0), (3, 2)]
>>> G.in_interactions([0,3], t=0)
[(3, 2)]
