Python can't read this ui file so to make it readable to python we need to process it with a script pyside-uic.
The command is:
<code>
pyside-uic mainwindow.ui -o mainwindow.py
</code>


The generated output file "mainwindow.py" is as follows:
Now, using PySide2 we will load the ui file and start our application:
<source lang="python">
#-*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'mainwindow.ui'

MainWindow.setMenuBar(self.menubar)

self.statusbar.setObjectName("statusbar")

we have to modify this mainwindow.py module:
 
<source lang="python">

And to run: <code>python mainwindow.py</code>
And to run it, just a <code>python main.py</code> will do the job.

Attention: a port of PySide to Qt 5.x started in 2014, the progress and more details about this project can be found under PySide 2

This page describes the use of Qt Creator to create Graphical Interfaces for your PySide Software. You will need Qt Creator, Pyside and PySide-Tools (pyuic and pyrcc).

If you don't know how to use Qt Creator, please go to Qt Creator Widget Tutorial .

At Qt Creator, create a new Qt Design Form, choose "Main Window" for template. And save as "mainwindow.ui" . Add a Qlabel to the center of the centralwidget.

And your mainwindow.ui 

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
 <property name="geometry">
 <rect>
 <x>0</x>
 <y>0</y>
 <width>82</width>
 <height>64</height>
 </rect>
 </property>
 <property name="windowTitle">
 <string>MainWindow</string>
 </property>
 <widget class="QWidget" name="centralwidget">
 <layout class="QGridLayout" name="gridLayout">
 <item row="0" column="0">
 <widget class="QLabel" name="label">
 <property name="text">
 <string>Hello World!</string>
 </property>
 </widget>
 </item>
 </layout>
 </widget>
 <widget class="QMenuBar" name="menubar">
 <property name="geometry">
 <rect>
 <x>0</x>
 <y>0</y>
 <width>82</width>
 <height>21</height>
 </rect>
 </property>
 </widget>
 <widget class="QStatusBar" name="statusbar"/>
 </widget>
 <resources/>
 <connections/>
</ui>

Now, using PySide2 we will load the ui file and start our application: 

# main.py
import sys
from PySide2.QtUiTools import QUiLoader
from PySide2.QtWidgets import QApplication
from PySide2.QtCore import QFile

if __name__ == "__main__":
    app = QApplication(sys.argv)

    file = QFile("mainwindow.ui")
    file.open(QFile.ReadOnly)

    loader = QUiLoader()
    window = loader.load(file)
    window.show()

    sys.exit(app.exec_())

And to run it, just a 

python main.py

will do the job.
