Change keyboard locks in Python

Question

Is there any way, in Python, to programmatically change the CAPS LOCK/NUM LOCK/SCROLL LOCK states?

This isn't really a joke question - more like a real question for a joke program. I intend to use it for making the lights do funny things...

On Linux here's a Python program to blink all the keyboard LEDs on and off:

import fcntl import os import time  KDSETLED = 0x4B32 SCR_LED  = 0x01 NUM_LED  = 0x02 CAP_LED  = 0x04  console_fd = os.open('/dev/console', os.O_NOCTTY)  all_on = SCR_LED | NUM_LED | CAP_LED all_off = 0  while 1:     fcntl.ioctl(console_fd, KDSETLED, all_on)     time.sleep(1)     fcntl.ioctl(console_fd, KDSETLED, all_off)     time.sleep(1)
