<｜begin▁of▁sentence｜>### Instruction:
Given an undirected graph with edge set [(0, 1), (1, 2), (2, 0)], can you use the Vertex.betweenness method in igraph to calculate the betweenness of a specified vertex (e.g., with id 1) and print the result?
### Response:
from igraph import Graph
import igraph as ig

g = ig.Graph(edges=[(0,1), (1,2), (2,0)])
vertex_id = 1 # Assuming you want to find the betweenness of vertex with id 1
vertex_betweenness = g.vs[vertex_id].betweenness()
print(f'Betweenness of vertex {vertex_id}: {vertex_betweenness}')
