<｜begin▁of▁sentence｜>### Instruction:
Given the American College Football Graph which you can read from a GML file named football.gml, can you use the Louvain method in cdlib to perform community detection? And can you compute the average distance within these communities?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

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

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

# Compute the average distance within the detected communities
avg_dist = evaluation.avg_distance(G, communities)

# Print the average distance
print(avg_dist.score)
