Interface between networkx and igraph

Question

I\'ve been working with networkx for quite some time now and it\'s been serving my purposes quite well with minimal tweaks until recently when I started looking into communi

Answer 1

As I try to store names of nodes/edges on both igraph or nx, this is my one-liner version which also transfers nodes names while transferring from igraph object, g, to nx:

G = nx.from_edgelist([(names[x[0]], names[x[1]])
                      for names in [g.vs['name']] # simply a let
                      for x in g.get_edgelist()], nx.DiGraph())

And the reverse way if G, a nx object, is given but an igraph object is needed:

g = igraph.Graph.TupleList(G.edges(), directed=True)

Of course these are not complete transfer as other node attributes and also edge attribute transfers are missing but I hope would be useful when you don't have them.

More verbose version that you have more control while transferring, from igraph to nx:

G = nx.DiGraph()
names = g.vs['name']
G.add_nodes_from(names)
G.add_edges_from([(names[x[0]], (names[x[1]])) for x in g.get_edgelist()])

From nx to igraph:

g = igraph.Graph(directed=True)
g.add_vertices(G.nodes())
g.add_edges(G.edges())
