Return an iterator over the out interactions present in a given snapshot.
Edges are returned as tuples in the order (node, neighbor).
- 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 an iterator over the edges of the flattened graph.
edge_iter – An iterator of (u,v) tuples of interaction.
Nodes in nbunch that are not in the graph will be (quietly) ignored. For directed graphs this returns the out-interaction.
>>> import dynetx as dn >>> G = dn.DynDiGraph() >>> G.add_interaction(0,1, 0) >>> G.add_interaction(1,2, 0) >>> G.add_interaction(2,3,1) >>> [e for e in G.out_interactions_iter(t=0)] [(0, 1), (1, 2)] >>> list(G.out_interactions_iter()) [(0, 1), (1, 2), (2, 3)]
