Overview

The Qt for Python project aims to provide a complete port of the PySide module to Qt 5. The development started on GitHub in May 2015. The project managed to port Pyside to Qt 5.3, 5. 4 & 5.5.

The PySide2 module was released mid June 2018 as a Technical Preview (supporting Qt 5.11), and it has been fully supported since Qt 5.12.

Qt for Python is available under LGPLv3/GPLv2 and commercial license for the following platforms:

What does PySide2 look like?

A simple Hello World example in PySide2 looks like this:

import sys
from PySide2.QtWidgets import QApplication, QLabel


if __name__ == "__main__":
    app = QApplication(sys.argv)
    label = QLabel("Hello World")
    label.show()
    sys.exit(app.exec_())
