windows - 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...

Answer 1

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)
