Updated version that is both python2 and python3 compatible (assuming pyobjc available for python3):

import objc
from Foundation import NSBundle, NSString

IOKit_bundle = NSBundle.bundleWithIdentifier_('com.apple.framework.IOKit')

functions = [("IOServiceGetMatchingService", b"II@"),
             ("IOServiceMatching", b"@*"),
             ("IORegistryEntryCreateCFProperty", b"@I@@I"),
            ]

objc.loadBundleFunctions(IOKit_bundle, globals(), functions)

def io_key(keyname):
    return IORegistryEntryCreateCFProperty(IOServiceGetMatchingService(0, IOServiceMatching("IOPlatformExpertDevice".encode("utf-8"))), NSString.stringWithString_(keyname), None, 0)

def get_hardware_uuid():
    return io_key("IOPlatformUUID")

def get_hardware_serial():
    return io_key("IOPlatformSerialNumber")

def get_board_id():
    return io_key("board-id").bytes().tobytes().decode("utf-8").rstrip("\x00")
