<｜begin▁of▁sentence｜>### Instruction:
Given the Political blogs Graph which you can read from a GML file named polblogs.gml, can you use the Louvain method in cdlib to perform community detection? And can you compute the average fraction of edges of a node of a community that point outside the community itself?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Create a graph
G = nx.read_gml('polblogs.gml')

# Apply a community detection algorithm
communities = algorithms.louvain(G)

# Compute the average fraction of edges of a node of a community that point outside the community itself
avg_out_degree_fraction = evaluation.avg_odf(G, communities)

# Print the result
print(avg_out_degree_fraction)
