PyQt

PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the 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).^[3] PyQt supports Microsoft Windows as well as various kinds of UNIX, including Linux and MacOS (or Darwin).^[4]

PyQt implements around 440 classes and over 6,000 functions and methods^[5] including:

a substantial set of GUI widgets
classes for accessing SQL databases (ODBC, MySQL, PostgreSQL, Oracle, SQLite)^[6]
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)^[7]

To automatically generate these bindings, Phil Thompson developed the tool SIP, which is also used in other projects.
