<｜begin▁of▁sentence｜>### Instruction:
As a fire inspector, you've been tasked with assessing the fire risks and hazards associated with a complex of five buildings. You need to analyze the network of interconnected paths within the complex and calculate the dyad census to identify the number of mutual, asymmetric, and null dyad pairs. This information will help in understanding the potential for fire hazards and safety risks within the interconnected buildings.
### Response:
from igraph import Graph

# Create a directed graph with edges
g = Graph(directed=True)
g.add_vertices(5)
g.add_edges([(0,1), (1,2), (2,3), (3,0), (1,0)])

# Calculate the dyad census
dyad_census = g.dyad_census()

# Display the dyad census results
print('Mutual:', dyad_census.mutual)
print('Asymmetric:', dyad_census.asymmetric)
print('Null dyads:', dyad_census.null)
