PyQt5

PyQt5 is a comprehensive set of Python bindings for the Qt cross-platform application toolkit, enabling developers to create graphical user interfaces (GUIs) for desktop and mobile systems. It leverages the robust C++ Qt framework, providing high-level APIs for UI development, multimedia, networking, databases, and more. The current stable version is 5.15.11, maintained by Riverbank Computing Ltd. While PyQt5 is mature and stable, its successor, PyQt6, is available, targeting Qt6.
