Yоu аre mоdeling а bаsic IT system using Pythоn classes. Given - NetworkDevice: A parent class is provided, which represents a generic network device. The class has: An attribute device_type (e.g., "Router", "Switch"). A method get_bandwidth_utilization() that always returns: "Bandwidth utilization is not available.". Task - Router: Create a child class Router that inherits from NetworkDevice. Override get_bandwidth_utilization() to implement the following: The method takes a list of integers, where each integer represents bandwidth usage in Mbps. The method returns the average bandwidth usage as a string, formatted as:"Average bandwidth utilization: [value] Mbps." If the list is empty, return: "No data available.". class NetworkDevice: def __init__(self, device_type): self.device_type = device_type def get_bandwidth_utilization(self): return "Bandwidth utilization is not available."
