### Response:
from igraph import Graph

# Define the edges for the graph
edges = [(0, 1), (1, 2), (2, 3), (3, 4), (4, 5), (5, 0)]

# Create the graph with the defined edges
g = Graph(edges=edges)

# Get the size of all vertices in the VertexCollection
vertex_sizes = g.vs.get_sizes()

# Print the sizes of all vertices
print(vertex_sizes)
