dynetx.classes.function.nodes(G, t=None)

Return a list of the nodes in the graph at a given snapshot.

Parameters:

• G (Graph opject) – DyNetx graph object
• t (snapshot id (default=None)) – If None the the method returns all the nodes of the flattened graph.

Returns:

nlist – A list of nodes. If data=True a list of two-tuples containing (node, node data dictionary).

Return type:

list

Examples

>>> import dynetx as dn
>>> G = dn.DynGraph()   # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> G.add_path([0,1,2], 0)
>>> dn.nodes(G, t=0)
[0, 1, 2]
>>> G.add_edge(1, 4, t=1)
>>> dn.nodes(G, t=0)
[0, 1, 2]
