networkx.DiGraph.succ¶

property
DiGraph.
succ
¶ Graph adjacency object holding the successors of each node.
This object is a readonly dictlike structure with node keys and neighbordict values. The neighbordict is keyed by neighbor to the edgedatadict. So
G.succ[3][2]['color'] = 'blue'
sets the color of the edge(3, 2)
to"blue"
.Iterating over G.succ behaves like a dict. Useful idioms include
for nbr, datadict in G.succ[n].items():
. A dataview not provided by dicts also exists:for nbr, foovalue in G.succ[node].data('foo'):
and a default can be set via adefault
argument to thedata
method.The neighbor information is also provided by subscripting the graph. So
for nbr, foovalue in G[node].data('foo', default=1):
works.For directed graphs,
G.adj
is identical toG.succ
.
