<｜begin▁of▁sentence｜>### Instruction:
Given a weighted graph with edges [('A', 'B', 5), ('B', 'C', 3), ('A', 'C', 1)], what is the local constraint of node 'A' with respect to 'C' using the local_constraint function in NetworkX?
### Response:
import networkx as nx

# Create a weighted graph
G = nx.Graph()
G.add_edge('A', 'B', weight=5)
G.add_edge('B', 'C', weight=3)
G.add_edge('A', 'C', weight=1)

# Calculate the local constraint of node 'A' with respect to 'C'
constraint = nx.local_constraint(G, 'A', 'C', weight='weight')
print('Local constraint of A with respect to C:', constraint)
