you can use this to save an image that has been copied to the clipboard (either using print screen or using windows key+shift+s) to a jpeg file just by double clicking,(i have tested it only on windows))

    name=(str(name))

    try:
        im.save(name+'.jpeg','JPEG')
        
    
    except:
        win32clipboard.OpenClipboard()
        data = win32clipboard.GetClipboardData()
        print("this text was previously copied to the clipboard not an image :\n---------------------------------------------------------------------------------------- \n",data)
        print("\n----------------------------------------------------------------------------------------")
        win32clipboard.CloseClipboard()
    else:

        print("\n\n the image has been saved with the name {}.jpeg ".format(name))
        
       
    
    time.sleep(1)
