<｜begin▁of▁sentence｜>### Instruction:
As a networkx enthusiast, you may encounter the need to calculate the vertex connectivity of a graph represented by a given edge set. This can be particularly important when analyzing network reliability or robustness. Let's explore how to accomplish this using the igraph library in Python.
### Response:
import igraph as ig

# Create a graph
edges = [(0, 1), (1, 2), (2, 3), (3, 0), (1, 3)]
graph = ig.Graph(edges)

# Calculate vertex connectivity
connectivity = graph.vertex_connectivity()

# Print the vertex connectivity
print('Vertex Connectivity:', connectivity)
