<｜begin▁of▁sentence｜>### Instruction:
As a film producer overseeing a movie project, imagine you're handling various aspects of production, including managing a team of actors. Each actor represents a vertex in a network, and their connections represent the relationships between them. Now, consider you're tasked with assessing the influence of a particular actor, let's say Actor 1, within this network. Using the "strength" metric, which measures an actor's overall influence based on their connections, you need to determine Actor 1's impact within the network. To achieve this, you'd utilize the `Graph.strength()` method from the production management tool, which provides insights into the significance of individual actors in shaping the dynamics of your movie's cast.
### Response:
from igraph import Graph

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

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

# Get a vertex from the graph
vertex_id = 1
vertex = g.vs[vertex_id]

# Calculate the strength of the vertex
vertex_strength = vertex.strength()

# Print the strength of the vertex
print(f'Strength of vertex {vertex_id}: {vertex_strength}')
