<｜begin▁of▁sentence｜>### Instruction:
Given a famous network like Zachary's karate club network, can you calculate the average local transitivity, treating vertices with less than two neighbors as having zero transitivity?
### Response:
from igraph import Graph

# Load a graph (could be from a file, e.g., 'graph_file.gml')
g = Graph.Famous('Zachary')  # using a famous graph for illustration

# Calculate average local transitivity with zero treatment for vertices with degree less than two
average_transitivity = g.transitivity_avglocal_undirected(mode='zero')

# Print the average local transitivity
print('Average local transitivity:', average_transitivity)
