How To Change Caps Lock Status Without Key Press

I am using a python program that is activate when pressing Caps Lock key and I want to be able to turn on/off the caps lock status when the program is active. I tried to send keys

Solution 1:

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)
