dynetx.classes.function.time_slice

dynetx.classes.function.time_slice(G, t_from, t_to=None)

Return an iterator for (node, degree) at time t.

The node degree is the number of edges adjacent to the node.

Parameters

Ggraph

A DyNetx graph.

t_from : snapshot id, mandatory

t_tosnapshot id, optional (default=None)

If None t_to will be set equal to t_from

Returns

Ha DynGraph object

the graph described by interactions in [t_from, t_to]

Examples

>>> import dynetx as dn
>>> G = dn.DynGraph()
>>> G.add_path([0,1,2,3], t=0)
>>> G.add_path([0,4,5,6], t=1)
>>> G.add_path([7,1,2,3], t=2)
>>> H = dn.time_slice(G, 0)
>>> H.edges()
[(0, 1), (1, 2), (1, 3)]
>>> H = dn.time_slice(G, 0, 1)
>>> H.edges()
[(0, 1), (1, 2), (1, 3), (0, 4), (4, 5), (5, 6)]
