Re: [igraph] how to iterate a vertex seq to find neighbors

Sorry, I misunderstood your question. You can use g.get_eid(mynode,  
myneighbor) to get the ID of an edge connecting mynode and myneighbour:

g.es[g.get_eid(mynode, myneighbor)]["weight"]

Alternatively, you can get all the weights and the node-neighbour  
pairs in advance into a dict and then use that dict to look up the  
weight:

weight_dict = dict(zip(g.get_edgelist(), g.es["weight"]))

weight_dict[mynode, myneighbour] will then give you the weight of the  
corresponding edge.
