<｜begin▁of▁sentence｜>### Instruction:
Given two graphs G with node attributes and an edge between nodes (0, 1) and H with node attributes and an edge between nodes ('a', 'b'), what is the lexicographic product of G and H? Use the 'lexicographic_product' function from NetworkX to compute this product graph and list its nodes and edges.
### Response:
import networkx as nx

# Create two graphs
G = nx.Graph()
G.add_node(0, a1=True)
G.add_edge(0, 1)

H = nx.Graph()
H.add_node('a', a2='Spam')
H.add_edge('a', 'b')

# Compute the lexicographic product
P = nx.lexicographic_product(G, H)

# List nodes and edges of the product graph
print(list(P.nodes(data=True)))
print(list(P.edges()))
