Given a famous 'petersen' graph, can you iterate over clusters in its vertex cover and print out the clusters?
### Response:
import igraph as ig

# Create a graph
g = ig.Graph.Famous('petersen')

# Compute a vertex cover of the graph
vertex_cover = ig.VertexCover(g)

# Iterate over the clusters in the vertex cover and print them
for cluster in vertex_cover:
    print(cluster)
