<｜begin▁of▁sentence｜>### Instruction:
Given the Karate Club graph provided by NetworkX, compute the group degree centrality for a group of nodes with identifiers [0, 1, 2, 3, 4]. What is the fraction of non-group members connected to these group members?
### Response:
import networkx as nx

# Create a graph
G = nx.karate_club_graph()

# Define the group of nodes for which we want to find the group degree centrality
S = [0, 1, 2, 3, 4]

# Calculate the group degree centrality
centrality = nx.group_degree_centrality(G, S)

print('Group degree centrality:', centrality)
