<｜begin▁of▁sentence｜>### Instruction:
Given a famous social network graph ('Zachary's karate club'), how can you calculate and output Burt's constraint scores for all members of the club?
### Response:
import igraph as ig
import json

# Create an example graph
g = ig.Graph.Famous('Zachary')

# Get the constraint scores for all vertices in the graph
constraint_scores = g.constraint()

# Optionally, convert the scores to json for representation or storage
constraint_scores_json = json.dumps(constraint_scores)

# Here's a snippet that could be used to print the scores
for vertex, score in enumerate(constraint_scores):
    print(f'Vertex {vertex}: Constraint {score}')
