<｜begin▁of▁sentence｜>### Instruction:
Given a social network represented as a graph where nodes are individuals and edges represent relationships between them, and a list of individuals [0, 1, 2, 3, 4] representing a group within this network, calculate the group degree centrality of this group, indicating the connectivity of the group to the rest of the network.
### Response:
import networkx as nx

# Create a graph
G = nx.karate_club_graph()

# Define a group of nodes
S = [0, 1, 2, 3, 4]

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

print('Group degree centrality:', centrality)
