What are some benefits of PySide besides the official support?

[paulober]

• PySide is licensed under the LGPL license, which means that it is easier to include in commercial projects compared to PyQt.
• It gives the programmer the ability to use QtQuick or QML to create the user interface.
• It enables the use of primary widget-based user interface resources.
• There are no official Python-specific resources for classes in PyQt5, which means that you can only use the data in C++. This can be quite confusing for a programmer who does not have extensive experience in C++ or Qt.
• PySide is the official set of Python bindings supported by the Qt company.
