This will print the UUID of every USB flash disk currently plugged in along with its device node:

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'))

With pyudev, each device object provides a dictionary-like interface for its attributes. You can list them all with device.keys(), e.g. UUID is for block devices is dev['ID_FS_UUID'].
