<｜begin▁of▁sentence｜>### Instruction:
In the course of evaluating potential risks and ensuring the safety of industrial work systems, consider a network of interconnected operation cycles represented by a Petersen graph modeled with NetworkX. To optimize the efficiency and safety of this network, we're interested in identifying the shortest sequence of operations that completes a cycle. Could you ascertain the minimum number of steps required within our operational network to form a complete cycle, analogous to determining the girth of the Petersen graph? This information is pivotal for minimizing exposure to potential hazards within the shortest operational cycle.
### Response:
import networkx as nx

# Create a graph
G = nx.petersen_graph()

# Calculate the girth of the graph
girth = nx.girth(G)

print('The girth of the graph is:', girth)
