Thank you!

I am a bit rusty on the syntax. Here is what I did:

reader = csv.DictReader(open("bipartite-test.csv"), dialect="excel")
g = igraph.Graph.DictList(vertices=None, edges=reader, directed=False)

Now do I need to loop over the g.vs["type"] or there is a quicker way?

Thanks very much,

Bipartite graphs in igraph are treated just like any other graph; the only
difference is that you should have a vertex attribute named "type" which
contains TRUE for one of the vertex groups and FALSE for the other. If you are
loading a graph from a CSV file, you can add this vertex attribute after
