g.nodes() from networkx is not working with random.choice()

Question

I\'m trying to generate random edges between random nodes but the line of code ab=choice(G.nodes()) is generating errors.

import networkx as nx
impo         


        

Answer 1

You can convert G.nodes() into a list format compatible with random.choice() by passing list(G.nodes()) instead of just G.nodes().

import networkx as nx
import matplotlib.pyplot as plt 
from random import choice      
G=nx.Graph()      
city_set=['a','b','c','d','e','f','g','h'] 
for each in city_set:     
    G.add_node(each)     
ab= choice(list(G.nodes())) 
print(ab)
