<｜begin▁of▁sentence｜>### Instruction:
As a Financial Advisor providing financial guidance and planning services, you may encounter scenarios where you need to assess the level of connection similarity in a network related to your client's investment portfolio diversification strategy. One way to measure this similarity is by calculating the assortativity coefficient based on vertex degrees using the GraphBase.assortativity_degree method. This coefficient can provide valuable insights into the network structure, particularly in understanding how nodes with similar degrees are connected within the graph.
### Response:
from igraph import Graph

# Assuming 'g' is an igraph Graph object
assortativity_coeff = g.assortativity_degree(directed=False)
print('Assortativity coefficient based on vertex degrees:', assortativity_coeff)
