Code:

brightness 0:
echo 0 > /sys/class/backlight/max77696-bl/brightness

brightness 51:      
echo 51 > /sys/class/backlight/max77696-bl/brightness

brightness full: 
echo 239 > /sys/class/backlight/max77696-bl/brightness

python command

import os
os.popen("echo 0 > /sys/class/backlight/max77696-bl/brightness")
os.popen("echo 51 > /sys/class/backlight/max77696-bl/brightness")
os.popen("echo 239 > /sys/class/backlight/max77696-bl/brightness")
