PyQt is dual-licensed with GPL v3 and the Riverbank Commercial License. If you do not intend on releasing your application under a GPL-compatible license (i.e. make your application open-source), you must pay for a commercial license. See More
GUI programming with Qt is built around the concept of signals and slots for communication between objects. A signal is emitted when an event occurs (e.g. a button is clicked), and slots are callable functions that handle the event (e.g. show a pop-up, when a button is clicked). This allows for flexibility when handling GUI events and results in a cleaner codebase. See More
Qt provides many widgets (buttons, textboxes, menus, et al.) out of the box, and they have a native look to them across all supported platforms: the same widget looks similar to the platform's native widget (e.g. a button in a PyQt application looks the same as a button on macOS, or Windows). On Linux systems, it changes according to the desktop environment. See More
PyQt has a straightforward API with its classes corresponding to Qt C++’s, and as such, the API documentation for C++ works for Python — the namespaces, properties, methods are all the same. If you have experience working with Qt and/or C++, you will find PyQt easy to work with. See More
