## What it is
QtPy is a Python library providing a uniform abstraction layer over the PyQt5, PyQt6, PySide2, and PySide6 Qt bindings, letting developers write a single codebase that works with any of them. It auto-detects the installed binding, normalizes module layouts, and handles API incompatibilities between Qt5 and Qt6.

## Use cases
- write a python gui app that works with both pyqt and pyside
- support qt5 and qt6 from a single codebase
- port a pyqt5 application to qt6 incrementally
- avoid conditional imports for different qt bindings
- let users choose their preferred qt binding via an environment variable

## When to choose
- you are building a desktop GUI in Python and want binding flexibility
- you maintain a library that must support multiple Qt bindings
- you are migrating a Qt5 codebase toward Qt6

## When to avoid
- you have already committed to a single Qt binding and never plan to change
- you need Qt bindings installed - QtPy does not bundle PyQt or PySide itself
- you are building a non-GUI application
