Example: Managing a Dictionary of Server Configurations and Optimizing Retrieval

Scenario:

Suppose you are managing server configurations using a dictionary.

server_config = {
    'server1': {'ip': '192.168.1.1', 'port': 8080, 'status': 'active'},
    'server2': {'ip': '192.168.1.2', 'port': 8000, 'status': 'inactive'},
    'server3': {'ip': '192.168.1.3', 'port': 9000, 'status': 'active'}
}

Function for Retrieval:

def get_server_status(server_name):
    return server_config.get(server_name, {}).get('status', 'Server not found')

Example Usage:

server_name = 'server2'
status = get_server_status(server_name)
print(f"{server_name} status: {status}")

In this example, the function get_server_status optimizes the retrieval of the server status by using the get method and providing a default value if the server name is not found.
