Hello,

You are iterating on G.degree(), which is fine when it is a dictionary. 
However regarding DiGraph documentation:
"Returns :   
nd : dictionary, or number
A dictionary with nodes as keys and degree as values or a number if a 
single node is specified."

So you may get an integer and thus cannot iterate on it.

You could use
if type(G.degree()) is int:
    lista.append(G.degree())
else:
    for i in G.degree().values():
       lista.append(i)

I'm quite surprised that a distributed graph API uses such inconsistent 
interface. I guess you'll have to live with it.

JM


PS : Try to code & document in English, it's much better especially when 
asking for help on this list, mixing spanish and english has few 
benefits since you may bother both spanish and english ppl :o)
