<｜begin▁of▁sentence｜>### Instruction:
Given a directed igraph graph consisting of 4 vertices and edges (0 -> 1, 0 -> 2, 1 -> 3, 2 -> 3), can you use the Vertex.successors method to obtain and print the list of immediate successors of the vertex with index 0?
### Response:
import igraph as ig

g = ig.Graph([(0, 1), (0, 2), (1, 3), (2, 3)], directed=True)
v = g.vs[0]
successors = v.successors()
print(successors)
