<｜begin▁of▁sentence｜>### Instruction:
Given a complete weighted undirected graph with 5 nodes where each edge has a weight of 1, how can the Christofides algorithm be used to approximate a solution for the traveling salesman problem using NetworkX?
### Response:
import networkx as nx

# Create a complete weighted undirected graph
G = nx.complete_graph(5)
nx.set_edge_attributes(G, values=1, name='weight')
G.edges(data=True)

# Use the Christofides algorithm to approximate a solution for the TSP problem
path = nx.approximation.christofides(G, weight='weight')

print(path)
