Re: [igraph] how to build a bipartite graph with python

[Simone Gabbriellini]

thanks Tamas,

I am trying to adapt your code to my case but I get this error:

import igraph

class Model:
    # init bipartite network
    def __init__(self, users, projects, directed):
        self.g = igraph.Graph(users + projects, directed = directed)
        self.g.vs["type"] = 0
        self.g.vs[users:]["type"] = 1

File "/Users/ogabbrie/Desktop/PANMIND/models/ABMsimulator/Model.py", line 7, in 
__init__
    self.vs["type"] = 0
TypeError: object of type 'int' has no len()

what I am trying to accomplish is to build a graph object after setting some 
parameters. Should I build my Model class as an extension of the Graph class?

Thanks for the remainder!

best,
