<｜begin▁of▁sentence｜>### Instruction:
Given a graph whose edge set is [(0, 1), (0, 2), (1, 2), (1, 3), (3, 4), (4, 5), (4, 6), (5, 6)], can you determine the nodes and edges that form the 2-shell using NetworkX?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()
G.add_edges_from([(0, 1), (0, 2), (1, 2), (1, 3), (3, 4), (4, 5), (4, 6), (5, 6)])

# Compute the k-shell of the graph
k_shell_subgraph = nx.k_shell(G, k=2)

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