Re: [igraph] uploading a bipartite graph from a csv file

Thank you very much! Just managed to get it done

Here is what I did

type_list = []
for vertex in g.vs:
if vertex["name"].startswith("#"):

g.vs["type"] = type_list

Perhaps not the best Python code but the projection returns the correct partitions!

BTW: do you guys keep track of the citations for the sake of funds? I am happy to provide a list of my own citations unless of course you have Google Scholar notifies you.

Thanks again,

You need to produce a list of length g.vcount() where the i-th element is True
or False and then simply say:

g.vs["type"] = your_list
