| PyQt is one of the most popular Python bindings for the Qt cross-platform C++ framework. PyQt was developed by [[http://www.riverbankcomputing.com|Riverbank Computing Limited]]. Qt itself is developed as part of the [[http://qt.io|Qt Project]]. PyQt provides bindings for Qt 4 and Qt 5. PyQt is distributed under a [[PyQt/PyQtLicensing|choice of licences]]: GPL version 3 or a commercial license. | |

| PyQt is a comprehensive set of Python bindings for the Qt cross-platform GUI/XML/SQL C++ framework from Nokia's Qt Development Frameworks (formerly Trolltech). PyQt provides bindings for Qt 2 and Qt 3. !PyQt4, a separate set of bindings, covers the Qt 4 series of releases. PyQt is dual-licensed under the GPL version 2 and a commercial license. There are also official Nokia bindings called [[http://www.pyside.org/|PySide]] available under LGPL. | PyQt is available in two editions: !PyQt4 which will build against Qt 4.x and 5.x and !PyQt5 which will only build against 5.x. Both editions can be built for Python 2 and 3. PyQt contains over 620 classes that cover graphical user interfaces, XML handling, network communication, SQL databases, Web browsing and other technologies available in Qt. |

| !PyQt4 is a set of Python bindings for [[http://www.trolltech.com/products/qt|Qt 4]] that exposes much of the functionality of Qt 4 to Python. It contains over 600 classes that cover graphical user interfaces, XML handling, network communication, SQL databases, Web browsing and other technologies in Qt. |
The latest iteration of PyQt is v5.11.3. It fully supports Qt 5.11.2. |

| Many of the features are described on the [[http://www.diotavelli.net/PyQtWiki/PyQt4|About PyQt4]] page on the !PyQt Wiki. | !PyQt4 runs on Windows, Linux, Mac OS X and various UNIX platforms. !PyQt5 also runs on Android and iOS. |

Phil Thompson was interviewed about PyQt for KDE Dot News in August 2006, and profiled for SunWorld Online in 2000.
Earlier Versions
This section describes PyQt version 3 (for Qt 3).
PyQt implements around 300 classes and over 5,750 functions and methods including:
- a substantial set of GUI widgets
classes for accessing SQL databases (ODBC, MySQL, PostgreSQL, Oracle)
QScintilla, Scintilla-based rich text editor widget
- data aware widgets that are automatically populated from a database
- an XML parser
- SVG support
- classes for embedding ActiveX controls on Windows (only in commercial version)
Earlier versions of PyQt included a graphical debugger called eric, written using PyQt, which can be used to debug PyQt and ordinary Python console applications. It's now available separately as eric4 from http://eric-ide.python-projects.org/index.html.
PyQt includes pyuic which generates Python code from GUI designs created with Qt Designer. This makes PyQt very useful as a rapid prototyping tool for applications that will eventually be (partly or completely) implemented in C++ because the user interface designs can be re-used without modification.
