Answer 1

使用 pyudev，每个设备对象都为其属性提供了一个类似字典的接口。您可以将它们全部列出device.keys()，例如 UUID 用于块设备dev['ID_FS_UUID']。

Answer 2

这将打印当前插入的每个 USB 闪存盘的 UUID 及其设备节点：

import pyudev

context = pyudev.Context()

for device in context.list_devices(subsystem='block', DEVTYPE='partition'):
    if (device.get('ID_USB_DRIVER') == 'usb-storage'):
        print '{0} {1}'.format(device.device_node, device.get('ID_FS_UUID'))
