Libnotify is part of the Gnome project and built on top of the Gnome library. Python has bindings to Gnome and we will take advantage of them to create desktop notifications. We can set the text, images, urgency, and create custom buttons in our notifications. Libnotify is a small and simple library and is a good place to start if you have never done any Gnome/Gtk programming. These examples will walk through all the options available.
