'''PyQt''' is a [[Python (programming language)|Python]] [[Language binding|binding]] of the [[cross-platform]] [[GUI]] toolkit [[Qt (toolkit)|Qt]], implemented as a Python [[Plug-in (computing)|plug-in]]. PyQt is [[free software]] developed by the [[United Kingdom|British]] firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including [[GNU General Public License]] (GPL) and commercial license, but not the [[GNU Lesser General Public License]] (LGPL).<ref>{{cite web|url=http://www.riverbankcomputing.com/commercial/license-faq |title=Riverbank &#124; Commercial &#124; License FAQ |publisher=Riverbankcomputing.com |access-date=2015-06-24}}</ref> PyQt supports [[Microsoft Windows]] as well as various kinds of [[Unix|UNIX]], including [[Linux]] and [[macOS]].<ref name="riverbankcomputing-2014">{{cite web | url=http://www.riverbankcomputing.co.uk/software/pyqt/intro | title=What is PyQt? | publisher=Riverbank Computing | access-date=2014-09-18}}</ref>

PyQt implements around 440 classes and over 6,000 functions and methods<ref>{{cite web | url=http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#introduction | archive-url=https://web.archive.org/web/20080429185425/http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html | url-status=dead| title=PyQt v4 - Python Bindings for Qt v4 | publisher=Riverbankcomputing | archive-date=2008-04-29 | access-date=2010-04-17 }}</ref> including:

* a substantial set of [[GUI widget]]s
* [[Class (computer science)|classes]] for accessing [[SQL]] [[database]]s ([[ODBC]], [[MySQL]], [[PostgreSQL]], [[Oracle database|Oracle]], [[SQLite]])<ref>{{cite web | title= QSqlDatabase Class Reference |url = http://pyqt.sourceforge.net/Docs/PyQt4/qsqldatabase.html |work=Pyqt.sourceforge.net| access-date=2014-09-25}}</ref>
* QScintilla, [[Scintilla (editing component)|Scintilla]]-based rich text editor widget
* data aware widgets that are automatically populated from a database
* an [[XML]] [[Parsing|parser]]
* [[Scalable Vector Graphics|SVG]] support
* classes for embedding [[ActiveX]] controls on Windows (only in commercial version)<ref>[https://wiki.python.org/moin/PyQt PythonInfo Wiki]</ref>

To automatically generate these bindings, Phil Thompson developed the tool [[SIP (software)|SIP]], which is also used in other projects.
