<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from some_graph.gml, can you use the update_attributes function in igraph to update the attributes of the vertex with index 0? You must set the color and size of the vertex as well as add a new label attribute. Afterwards, print out the updated attributes of the vertex.
### Response:
from igraph import Graph

# Load a graph from a file
g = Graph.Read('some_graph.gml')

# Update attributes of the vertex with index 0
vertex_attributes = {'color': 'blue', 'size': 10}
additional_attributes = {'label': 'start'}
g.vs[0].update_attributes(vertex_attributes, additional_attributes)

# Print updated attributes of vertex 0
print(g.vs[0].attributes())
