PyGObject is a Python package which provides bindings for GObject based libraries such as GTK, GStreamer, WebKitGTK, GLib, GIO and many more.

It supports Linux, Windows and macOS and works with Python 3.5+ and PyPy3. PyGObject, including this documentation, is licensed under the LGPLv2.1+.

If you want to write a Python application for GNOME or a Python GUI application using GTK, then PyGObject is the way to go. For more information on specific libraries check out the “Python GTK 3 Tutorial” and the “Python GI API Reference”.

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

window = Gtk.Window(title="Hello World")
window.show()
window.connect("destroy", Gtk.main_quit)
Gtk.main()

How does it work?

_images/overview.svg

PyGObject uses glib, gobject, girepository, libffi and other libraries to access the C library (libgtk-3.so) in combination with the additional metadata from the accompanying typelib file (Gtk-3.0.typelib) and dynamically provides a Python interface based on that information.
