{{Main|List of language bindings for GTK}}

'''PyGTK''' is a set of [[Python (programming language)|Python]] [[Adapter pattern|wrappers]] for the [[GTK]] [[graphical user interface]] [[library (computer science)|library]]. PyGTK is [[free software]] and licensed under the [[LGPL]]. It is analogous to [[PyQt]]/[[PySide]] and [[wxPython]], the Python wrappers for [[Qt (framework)|Qt]] and [[wxWidgets]], respectively. Its original author is [[GNOME]] developer James Henstridge. There are six people in the core development team, with various other people who have submitted patches and bug reports. PyGTK has been selected as the environment of choice for applications running on [[One Laptop Per Child]] systems.

PyGTK was phased out with the transition to GTK version 3 and be replaced with PyGObject,<ref>{{cite web|url=https://wiki.gnome.org/PyGObject|title=PyGObject|publisher=wiki.gnome.org}}</ref><ref>{{cite web|url=https://www.openhub.net/p/pygobject|title=Black Duck Open Hub: PyGObject}}</ref> which uses [[GObject Introspection]] to generate bindings for Python and other languages on the fly. This is expected to eliminate the delay between GTK updates and corresponding [[language binding]] updates, as well as reduce maintenance burden on the developers.<ref>{{cite web|url=http://live.gnome.org/action/recall/GObjectIntrospection?action=recall&rev=69|archive-url=https://archive.today/20120711012345/http://live.gnome.org/action/recall/GObjectIntrospection?action=recall&rev=69|url-status=dead|archive-date=2012-07-11|title=GObject Introspection}}</ref>

==Syntax==
The Python code below will produce a 200x200 pixel window with the words "[["Hello, World!" program|Hello World]]" inside.

<syntaxhighlight lang="python">
import gtk

def create_window():
    window = gtk.Window()
    window.set_default_size(200, 200)
    window.connect("destroy", gtk.main_quit)

    label = gtk.Label("Hello World")
    window.add(label)

    label.show()
    window.show()

create_window()
gtk.main()
</syntaxhighlight>

PyGObject provides a wrapper for use in Python programs when accessing GObject libraries. [[GObject]] is an object system used by [[GTK]], [[GLib]], [[GIO (software)|GIO]], [[GStreamer]] and other libraries.

Like the GObject library itself, PyGObject is licensed under the [[GNU Lesser General Public License|GNU LGPL]], 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.

===Notable applications that use PyGObject===
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.

* [[Gramps_(software)|Gramps]]
* [[Meld (software)|Meld]]
* [[Pitivi]]
* [[PyChess]]
* [[Quod Libet (software)|Quod Libet]]
