PyGTK has been selected as the environment of choice for applications running on One Laptop Per Child systems. PyGTK will be phased out with the transition to GTK version 3 and be replaced with PyGObject, which uses GObject Introspection to generate bindings for Python and other languages on the fly.

, so it is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single-purpose scripts to large full-featured applications. PyGObject can dynamically access any GObject libraries that use GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to GObject library it is instantly available as a Python API without the need for intermediate Python glue.

PyGObject has replaced PyGTK, but it has taken a considerable amount of time for many programs to be ported. Most of the software listed here has an older version which used PyGTK. * Ex Falso * Gramps * Meld * Pitivi *
