From the docs page here: https://archlinuxarm.org/wiki/Raspberry_Pi it notes:

GPIO
To be able to use the GPIO pins from Python, use the RPi.GPIO library. Install the python-raspberry-gpio package from the AUR.

have you installed that package from the AUR yet? It seems like that is required setup that you need to do if you want to use the GPIO pins with Arch linux.

Unfortunately, the maintainer has already deleted the repo and ran away.

What bad luck!

Now, I have found other available libraries

#!/usr/bin/env python

from luma.core.interface.serial import i2c
from luma.core.render import canvas
from luma.oled.device import ssd1306
from time import sleep

serial = i2c(port=1, address=0x3C)
device = ssd1306(serial, rotate=2)

# Box and text rendered in portrait mode
with canvas(device) as draw:
    draw.rectangle(device.bounding_box, outline="white", fill="black")
    draw.text((10, 40), "Hello World!", fill="white")
sleep(10)
