Answer 1

Use sendkeys to change the status and keyboardleds to change the LED indicators.

sendkeys:

From another SO dicussion:

import SendKeys

SendKeys.SendKeys("""
{CAPSLOCK}
{SCROLLOCK}
{NUMLOCK}
""")

keyboardleds:

This package seems to work only for POSIX (which is OK if you're using Ubuntu), and you can read more here.

Answer 2

On Linux:

import fcntl
import os

KDSETLED = 0x4B32

console_fd = os.open('/dev/console', os.O_NOCTTY)

# Turn on caps lock
fcntl.ioctl(console_fd, KDSETLED, 0x04)

# Turn off caps lock
fcntl.ioctl(console_fd, KDSETLED, 0)
