python script for gfx hat (LCD for raspberry)

[domoticity]

Hy,
i have bought a LCD for my beautifull Pi :)

My LCD is the GFX hat : https://shop.pimoroni.com/products/gfx-hat

There is an Example for script python but i don't understand, i am a very very very rookie in Python Scripts.

what i am looking for with my lcd :

Below the screen : display text like "Hello", "name", etc...

Top the screen : display Pictogram wich are in this folder "/diagbox/pictures"

for example :
When the Pi starts, switch on the LCD and display "Hello, boot in progress"
After, when the wlan0 and eth0 are up, display a pictogramm for the eth0 and for the wlan0

And leave the screen on, as long as the pi is on.


Thank by Advance

Thereafter the script give with the Equipment :

#!/usr/bin/env python

import signal

from gfxhat import touch, lcd, backlight, fonts
from PIL import Image, ImageFont, ImageDraw

This basic example prints the text "Hello World" in the middle of the LCD
