Change Windows Background from Python

问题

Does anyone know a way to change the Windows Desktop Wallpaper with python so that the change is permanent? I have found this code

import ctypes
SPI_SETDESKWALLPAPER = 20 
ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, "myimage.jpg" , 0)

This code works, but once you log off and log on again, the background is back to the original image. I would prefer a solution that does not require any registry edit, and I would like something that works with Windows XP and 7 if it is possible.

回答1:

This solution combines several of the comments made, and works for me:

import ctypes
import os
drive = "C:\\"
folder = "images"
image = "test.jpg"
image_path = os.path.join(drive, folder, image)
SPI_SETDESKWALLPAPER = 20 
ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, image_path, 3)

(Note that you should determine the absolute path to your image, and change as needed. Also convert the image to BMP if you need to use it on XP. You can easily convert the image using Pillow)
