What is PyQt?
PyQt connects the Qt C++ cross-platform framework with the Python language, it is a GUI module.
Qt is more than a GUI toolkit, which is why it features abstractions of network sockets or threads, along with Unicode, SQL, databases, SVG, OpenGL, XML, an operational we browser, a service system and a vast array of GUI widgets.
The principle on which a Qt class functions is related to a slot mechanism responsible for offering communication between items with the purpose of designing re-usable software components with ease.
Also, Qt comes with Qt Designer, a tool that acts as a graphical user interface. PyQt can design Python code from Qt Designer, while adding new GUI controls when both Qt Designer and Python programming language are used.

PyQt’s classes are classified into distinct modules, as it follows:
- QtCore: The QtCore setting features the core non-GUI functionality, being employed for items such as time, files, directories, distinct data types, threads or processes.
- QtGui: The QtGui features graphical components and related classes, such as buttons, windows, status bars, bitmaps, colours or fonts.
- QtNetwork: The QtNetwork is meant to be used for network programming purposes and it eases the coding of TCP/ IP and UDP clients or servers.
- QtXml: The QtXml servers the purposes of working with XML files, offering implementation for SAX and DOM APIs.
- QtSvg: The QtSvg features classes for revealing the contents of SVG files, SVG being a language meant to describe two-dimenl graphics or graphical applications in XML
- QtOpenGL: The QtOpenGL is meant for rendering both 3D and 2D graphics via the OpenGL library.
- QtSql: The QtSql offers means for working with databases.
