python登记设备的代码

以下是一个基于Python语言的设备登记代码示例：

devices = {}

def register_device(device_name, device_type):
    if device_name in devices:
        print("Error: The device is already registered.")
    else:
        devices[device_name] = device_type
        print("The device " + device_name + " has been registered as a " + device_type + ".")

def unregister_device(device_name):
    if device_name in devices:
        del devices[device_name]
        print("The device " + device_name + " has been unregistered.")
    else:
        print("Error: The device is not registered.")

# Example usage
register_device("Pi1", "Raspberry Pi")
register_device("Arduino1", "Arduino")
unregister_device("Pi1")

此代码使用Python的字典来存储已注册设备的名称和类型。`register_device`函数用于添加设备的名称和类型到设备字典中。如果设备已经被注册，则输出错误信息。`unregister_device`函数用于从设备字典中删除已注册设备。如果要删除的设备未在设备字典中注册，则输出错误信息。

本代码示例是一种较为简单的设备登记代码，可以根据实际需求进行扩展和改进。
