<｜begin▁of▁sentence｜>### Instruction:
As a graph analyst, you have built a network graph to represent relationships between different entities in a complex system. You now need to utilize the get_vertices method provided by the graph-tool library to retrieve the collection of vertices from your graph. Once you have obtained the VertexCollection, your task is to print the list of vertices it contains. This will help you better understand the structure of your graph and the entities it comprises, allowing you to gain valuable insights from the data.
### Response:
from graph_tool.all import Graph, GraphArtist

# Create a Graph object
g = Graph()

# Add three vertices to the graphvg = g.add_vertex(3)

# Create a GraphArtist object, passing the graph
ga = GraphArtist(g)

# Use the get_vertices method to retrieve the VertexCollection artistsva = ga.get_vertices()

# Print the retrieved VertexCollectionvo = list(va)
print(vo)
