<｜begin▁of▁sentence｜>### Instruction:
Given an undirected graph with edges [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0)], can you use the Graph.radius function in igraph to calculate the radius of the graph?
### Response:
from igraph import Graph

# Create an undirected graph
g = Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 4), (4, 0)], directed=False)

# Calculate the radius of the graph
radius = g.radius()

# Print the radius
print('The radius of the graph is:', radius)
