<｜begin▁of▁sentence｜>### Instruction:
Given a graph represented by edges [(0, 1), (1, 2), (2, 3), (3, 0), (0, 2)], calculate the overall vertex connectivity as well as the vertex connectivity between vertex 0 and vertex 3. How many vertices must be removed in each case to disconnect the specified vertices or the graph?
### Response:
from igraph import Graph

# Creating a graph with predefined edges
g = Graph([(0, 1), (1, 2), (2, 3), (3, 0), (0, 2)])

# Calculate the overall vertex connectivity
connectivity = g.vertex_connectivity()

# Print the overall vertex connectivity
print('Overall vertex connectivity:', connectivity)

# Calculate the vertex connectivity between two specific vertices
specific_connectivity = g.vertex_connectivity(source=0, target=3)

# Print the vertex connectivity between vertex 0 and vertex 3
print('Vertex connectivity between 0 and 3:', specific_connectivity)
