[igraph] Bidirectional edges in Python

[Gábor Tóth]

Dear All,

I need to represent two directional information flow, and I would not like to use parallel edges, I am wondering if I can make bidirectional edges in Python. For instance a simple test code, how should I rewrite it so that the edge between kaka and hah be bidirectional?

from igraph import *

g = Graph()

g.to_directed()

g.add_vertex('kaka')

g.add_vertex('hah')

g.add_edges(("kaka","hah"))

g.add_edges(("hah","kaka"))

visual_style = {}

visual_style["vertex_label"] = g.vs["name"]

layout = g.layout("kamada_kawai")

plot(g, **visual_style)

print g.summary()

Thanks,

Gabor
