QtPy

QtPy provides an abstraction layer on top of the various Qt bindings (PyQt5, PyQt6, PySide2, and PySide6), allowing developers to write Python GUI applications that can run with any of these backends without modifying code. It automatically detects and uses the available binding, or can be configured to prefer a specific one. The current version is 2.4.3, with a regular release cadence addressing compatibility and feature enhancements.
