<｜begin▁of▁sentence｜>### Instruction:
Given a shell constructor with parameters [(10, 20, 0.8), (20, 40, 0.8)] representing two shells where the first shell has 10 nodes, 20 edges and a ratio of inter-shell to intra-shell edges of 0.8, and the second shell has 20 nodes, 40 edges and the same ratio of 0.8; how can we create and analyze a random shell graph using NetworkX?
### Response:
import networkx as nx

# Define the constructor for the shell graph
constructor = [(10, 20, 0.8), (20, 40, 0.8)]

# Generate a random shell graph
G = nx.random_shell_graph(constructor)

# Print information about the created graph
print(nx.info(G))
