I'm new to networkx, and I want to extract a random node from the erdos_renyi graph, I'm using this code, but I get an empty list
N = 1000
p = 0.01
G = nx.erdos_renyi_graph(N, p)
node = list(random.choice(G.nodes()))
You're just a little bit off on your calling sequence:
node = list(random.choice(G.nodes()))
G.nodes()
is a node view of the graph; you need a list of nodes, G.nodes
node = [ random.choice(list(G.nodes)) ]
Turn the node view into a list, grab a random element form that, and then stuff it into a list (I'm not sure why you wanted a list of one element).
