Automatically update wallpaper with Python on Ubuntu as bing Wallpaper

Because the WindowsPhone mobile phone is used, there is a mobile phone lock screen which is automatically updated to bing wallpaper every day. It is quite easy to use, so I want to implement this function under Ubuntu, I have been tossing for a week or two intermittently. However, in the end, all the functions are implemented. The main functions are automatic update and manual refresh. The image is automatically downloaded to the user's image directory.
