<｜begin▁of▁sentence｜>### Instruction:
Given a graph generated using the Erdos-Renyi model with 10 nodes and 20 edges, can you use the igraph library to find out how many clusters the graph contains?
### Response:
from igraph import Graph

# Generate a simple graph example
g = Graph.Erdos_Renyi(n=10, m=20)

# Get the clusters of the graph
clusters = g.clusters()

# Calculate the number of clusters
number_of_clusters = len(clusters)

# Print the number of clusters
print(f'Number of clusters: {number_of_clusters}')
