<｜begin▁of▁sentence｜>### Instruction:
Given a graph whose edge set is [(0, 1), (1, 2), (2, 3), (3, 4), (4, 5), (1, 3), (2, 4), (5, 0)], can you compute the 2-shell of the graph using NetworkX?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()
G.add_edges_from([(0, 1), (1, 2), (2, 3), (3, 4), (4, 5), (1, 3), (2, 4), (5, 0)])

# Calculate the k-shell
k_shell_subgraph = nx.k_shell(G, k=2)

print('Nodes in the 2-shell:', k_shell_subgraph.nodes())
print('Edges in the 2-shell:', k_shell_subgraph.edges())
