how to use python to get display from environment

Question

I want to detect cursor position and colour quickly (less than 0.1 sec)

I read this article and want to try he's last method (Xlib)

However, when I run os.getenv("DISPLAY"), it returns None

Does anyone know how to fix this or offer me a new method to achieve my goal?

System: MacBook Pro, macOS 10.15.4

Xlib is usually not available on macOS. You may consider using a library such as pynput or pyautogui to achieve what you want to do instead.

e.g. with pynput

from pynput.mouse import Controller

mouse = Controller()
print(mouse.position)  # (x, y) coordinates tuple
