pred
¶ Graph adjacency object holding the predecessors of each node.
This object is a read-only dict-like structure with node keys and neighbor-dict values. The neighbor-dict is keyed by neighbor to the edge-data-dict. So
G.pred[2][3]['color'] = 'blue'
sets the color of the edge(3, 2)
to"blue"
.Iterating over G.pred behaves like a dict. Useful idioms include
for nbr, datadict in G.pred[n].items():
. A data-view not provided by dicts also exists:for nbr, foovalue in G.pred[node].data('foo'):
A default can be set via adefault
argument to thedata
method.
