interactions(G, nbunch=None, t=None)¶
Return the list of edges present in a given snapshot.
Edges are returned as tuples in the order (node, neighbor).
- G (Graph opject) – DyNetx graph object
- nbunch (iterable container, optional (default= all nodes)) – A container of nodes. The container will be iterated through once.
- t (snapshot id (default=None)) – If None the the method returns all the edges of the flattened graph.
edge_list – Edges that are adjacent to any node in nbunch, or a list of all edges if nbunch is not specified.
list of edge tuples
Nodes in nbunch that are not in the graph will be (quietly) ignored. For directed graphs this returns the out-edges.
>>> G = dn.DynGraph() >>> G.add_path([0,1,2], t=0) >>> G.add_edge(2,3, t=1) >>> dn.interactions(G, t=0) [(0, 1), (1, 2)] >>> dn.interactions(G) [(0, 1), (1, 2), (2, 3)] >>> dn.interactions(G, [0,3], t=0) [(0, 1)]
