Re: [igraph] how to select transitive node in neighborhood

Dear Simone,

Sidenote: you could use random.choice here as you are sampling only  
one node.

What I'd do:

node_A = ...
candidates = g.vs[in_nei].select(attribute1_ne = 0, attribute2_le = 20)
filtered_candidates = []
for node_B in candidates:
  for node_C in g.vs[in_nei]:
    if g.are_connected(node_B.index, node_C.index):
      filtered_candidates.append(node_B)
node_B = random.choice(filtered_candidates).index

I hope that's what you wanted.
