<｜begin▁of▁sentence｜>### Instruction:
Given a graph loaded from 'graph_data.gml', can you calculate the assortativity score based on a numeric vertex property such as 'degree'?
### Response:
from igraph import Graph

# Load a graph from a file
g = Graph.Read_GML('graph_data.gml')

# Compute and print out the assortativity based on a vertex attribute called 'degree'
# The 'degree' attribute should be a numeric property
g.vs['degree'] = g.degree()
assortativity_score = g.assortativity('degree', directed=False)
print(assortativity_score)
