<｜begin▁of▁sentence｜>### Instruction:
Given a weighted graph with nodes 1, 2, 3, and 4, with edges and weights as follows: (1,2) with weight 5, (1,3) with weight 3, (2,4) with weight 1, (3,4) with weight 7, and (1,4) with weight 1, how can we find the local constraint of node 1 with respect to node 3?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add nodes to the graph
G.add_nodes_from([1, 2, 3, 4])

# Add edges with weights
g.add_edge(1, 2, weight=5)
g.add_edge(1, 3, weight=3)
g.add_edge(2, 4, weight=1)
g.add_edge(3, 4, weight=7)
g.add_edge(1, 4, weight=1)

# Compute local constraint of node 1 with respect to node 3
constraint = nx.local_constraint(G, 1, 3, weight='weight')
print('Local constraint of node 1 with respect to node 3 is:', constraint)
