Re: [igraph] how to translate from R to Python...

It should work this way, so let's try to break it down to smaller  
components:

- g.es.select(color="green") or g.es(color="green") should return an  
edge sequence that consists of all edges having color="green". Check  
that manually by converting it into a list of edge IDs:
idlist = [e.index for e in g.es.select(color="green")]

- if that's OK, move on to adj(g.es.select(color="green")) which  
should return the IDs of the nodes that have at least one edge  
adjacent to them
