I suppose one could argue that there is some ethical commitment due to the history, but I'm not seeing any commitment in a legal technical sense. I think that after all technical reliance from PyQt is replaced by technical reliance on PySide, the project is free

Main difference between these two libraries is in licensing. The free-to-use version of PyQt is licensed under GNU General Public License (GPL) v3 but PySide is licensed under GNU Lesser General Public License (LGPL). This means that PyQt is limited GPL-licensed applications unless you purchase its commercial version, while PySide may be used in non-GPL applications without any additional fee. However, note that both these libraries are separate from Qt itself which also has a free-to-use, open source version and a paid, commercial version.

We've already introduced the Qt Widgets APIwhich is well-suited for building desktop applications. But Qt also provides a declarative API in the form of Qt Quick/QML.Using Qt Quick/QML you have access to the entire Qt framework for building your applications. Your UI consists of two parts: the Python code whichhandles the business logic and the QML which defines the structure and behavior of the UI itself. You can control the UI from Python, or useembedded Javascript code to handle events and animations.Qt Quick/QML is ideally suited for building modern touchscreen interfaces for microcontrollers or device interfaces -- for example, buildinginterfaces for microcontrollers like the Raspberry Pi. However you can also use it on desktop to build completely customized applicationexperiences, like those you find in media player applications like Spotify, or to desktop games.Installation pip install pyqt6 or pip install pyside6A simple Hello World app in PyQt6 with QML.

Find plenty of support and online learning resources to help you develop your application.Qt (and by extension PyQt & PySide) is not just a GUI library, but a complete application development framework. In addition to standard UI elements, such as widgets and layouts, Qt provides MVC-like data-driven views (spreadsheets, tables), database interfaces & models, graph plotting, vector graphics visualization, multimedia playback, sound effects & playlists and built-in interfaces for hardware such as printing. The Qt signals and slots models allows large applications to be built from re-usable and isolated components.While other toolkits can work great when building small & simple tools, Qt really comes into its own for building real commercial-quality applications where you will benefit from the pre-built components. This comes at the expense of a slight learning curve. However, for smaller projects Qt is not really any more complex than other libraries.Qt Widgets-based applications use platform native widgets to ensure they look and feel at home on Windows, macOS and Qt-based Linux desktops.Installation pip install pyqt6 or pip install pyside6A simple hello world application in PyQt6, using the Qt Widgets API is shown below.PyQt6PySide6pythonfrom PyQt6.QtWidgets import QMainWindow, QApplication, QPushButtonimport sysclass MainWindow(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle("Hello World") button = QPushButton("My simple app.") button.pressed.connect(self.close) self.setCentralWidget(button) self.show()app = QApplication(sys.argv)w = MainWindow()app.exec()pythonfrom PySide6.QtWidgets import QMainWindow, QApplication, QPushButtonimport sysclass MainWindow(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle("Hello World") button = QPushButton("My simple app.") button.pressed.connect(self.close) self.setCentralWidget(button) self.show()app = QApplication(sys.argv)w = MainWindow()app.exec() As you can see, the code is almost identical between PyQt & PySide, so it's not something to be concerned about when you start developing with either: you can always migrate easily if you need to.Hello world application built using PyQt6, running on Windows 11Before the Qt Company (under Nokia) released the officially supported PySide library in 2009, Riverbank Computing had released PyQt in 1998.

Wheel but provides a wrapper around other existing frameworks such as Tkinter, Qt (PySide 2), WxPython and Remi. By doing so, it lowers the barrier to creating a GUI but also allows you to easily migrate from one GUI framework to another by simply changing the import statement.While there is a separate port of PySimpleGUI for each of these frameworks, the Tkinter version is considered the most feature complete. Wrapping other libraries comes at a cost however — your applications will not be able to exploit the full capabilities or performance of the underlying libraries. The pure-Python event loop can also hinder performance by bottlenecking events with the GIL. However, this is only really a concern when working with live data visualization, streaming or multimedia applications.There is a fair amount of good resources to help you learn to use PySimpleGUI, including an official Cookbook and a Udemy course offered by the developers themselves. According to their project website, PySimpleGUI was initially made (and later released in 2018) because the lead developer wanted a 'simplified' GUI framework to use in his upcoming project and wasn't able to find any that met his needs.Installation pip install pysimpleguipythonimport PySimpleGUI as sglayout = [ [sg.Button("My simple app.")]]window = sg.Window("Hello World", layout)while True: event, values = window.read() print(event, values) if event == sg.WIN_CLOSED or event == "My simple app.": breakwindow.close()Hello world application built using PySimpleGUI, running on Windows 11PySimpleGUI is licensed under the same LGPL v3 license as PySide, which allows its use in proprietary applications but modifications to the framework itself must be released as open source.PySimpleGUI WebsitePySimpleGUI CookbookGitHub RepositoryWxPythonBest for simple portable desktop applicationsWxPython is a wrapper for the popular, cross-platform GUI toolkit called WxWidgets.

In fact, many people became interested in programming, because they played games and wantedto create their own. Creating a computer game will help improving your programming skills.TetrisThe Tetris game is one of the most popular computer games ever created. The original game was designed and programmedby a Russian programmer Alexey Pajitnov in 1985. Since then, Tetris is available on almost every computer platform in lots of variations. Even my mobile phone has a modified version of the Tetris game. Tetris is called a falling block puzzle game. In this game, we have seven different shapes called tetrominoes.S-shape, Z-shape, T-shape, L-shape, Line-shape, MirroredL-shape and a Square-shape.Each of these shapes is formed with four squares. The shapes are falling down the board.The object of the Tetris game is to move and rotate the shapes, so that they fit as much as possible. If we manage to form a row, the row is destroyed and we score. We play the Tetris game until we top out.Figure: TetrominoesPySide is a toolkit designed to create applications. There are other libraries which are targeted at creating computer games.Nevertheless, PySide and other application toolkits can be used to create games.The developmentWe do not have images for our Tetris game, we draw the tetrominoes using the drawing API available in the PySide programming toolkit.

One of the best programming languages for web development due to the array of options it provides you with. It supports frameworks such as Pyramid and Django, micro-frameworks like Bottle and Flask, and advanced CMS like Django CMS and Plone.These frameworks are flexible, scalable, secure, and come with various modules and standard libraries useful for simplifying tasks such as database interaction, content management, etc. Its standard library also supports internet protocols like HTML, XML, FTP, IMAP, POP, etc.Additionally, its Package Index has other useful libraries, including Requests, Feedparser, Beautiful Soup, Paramiko, and Twisted Python.Machine learning (ML) and artificial intelligence (AI): AI and ML projects are different from traditional software projects and models. They require different skill sets, technologies, and tools, and a stable and reliable language. Python is equipped with such functionalities and flexibility to handle unique project requirements.Its simplicity, platform independence, resourceful libraries, consistency, and active development community strengthen people’s use of Python in their AI and ML projects.Python packages famous for AI and ML include SciPy for sophisticated computing, Seaborn to visualize data, Pandas for data analysis, IPython for parallel computing, and recording work sessions TensorFlow, and Keras for ML, NumPy for high-level scientific computing, and more.Desktop GUI creation: As Python has a module architecture and works on multiple Oss, you can create desktop GUIs using an efficient text-processing tool, framework, or a Python module, such as PyQt4, PyQt5, WxPython, PyGtk, PySide, PyGUI, Tkinter, etc.Software development and rapid prototyping: Python applications and packages aim at simplifying software development processes. Python can help you develop web and desktop applications, along with complex applications capable of numeric and scientific computing.Developers use Python extensively, even for build-control, management, and testing. For these individual purposes, you can use SCons, Trac or Roundup, and Apache Gump or Buildbot, respectively.Other uses: Python is used. Getting Started with PySide.

Mathematically a board is a simple list of numbers.#!/usr/bin/python"""ZetCode PySide tutorialThis is a simple Tetris clonein PySide.author: Jan Bodnarwebsite: zetcode.comlast edited: August 2011"""import sys, randomfrom PySide import QtCore, QtGuiclass Communicate(QtCore.QObject): msgToSB = QtCore.Signal(str)class Tetris(QtGui.QMainWindow): def __init__(self): super(Tetris, self).__init__() self.setGeometry(300, 300, 180, 380) self.setWindowTitle('Tetris') self.Tetrisboard = Board(self) self.setCentralWidget(self.Tetrisboard) self.statusbar = self.statusBar() self.Tetrisboard.c.msgToSB[str].connect(self.statusbar.showMessage) self.Tetrisboard.start() self.center() def center(self): screen = QtGui.QDesktopWidget().screenGeometry() size = self.geometry() self.move((screen.width()-size.width())/2, (screen.height()-size.height())/2)class Board(QtGui.QFrame): BoardWidth = 10 BoardHeight = 22 Speed = 300 def __init__(self, parent): super(Board, self).__init__() self.timer = QtCore.QBasicTimer() self.isWaitingAfterLine = False self.curPiece = Shape() self.nextPiece = Shape() self.curX = 0 self.curY = 0 self.numLinesRemoved = 0 self.board = [] self.setFocusPolicy(QtCore.Qt.StrongFocus) self.isStarted = False self.isPaused = False self.clearBoard() self.c = Communicate() self.nextPiece.setRandomShape() def shapeAt(self, x, y): return self.board[(y * Board.BoardWidth) + x] def setShapeAt(self, x, y, shape): self.board[(y * Board.BoardWidth) + x] = shape def squareWidth(self): return self.contentsRect().width() / Board.BoardWidth def squareHeight(self): return self.contentsRect().height() / Board.BoardHeight def start(self): if self.isPaused: return self.isStarted = True self.isWaitingAfterLine = False self.numLinesRemoved = 0 self.clearBoard() self.c.msgToSB.emit(str(self.numLinesRemoved)) self.newPiece() self.timer.start(Board.Speed, self) def pause(self): if not self.isStarted: return self.isPaused = not self.isPaused if self.isPaused: self.timer.stop() self.c.msgToSB.emit("paused") else: self.timer.start(Board.Speed, self) self.c.msgToSB.emit(str(self.numLinesRemoved)) self.update() def paintEvent(self, event): painter = QtGui.QPainter(self) rect = self.contentsRect() boardTop = rect.bottom() - Board.BoardHeight * self.squareHeight() for i in range(Board.BoardHeight): for j in range(Board.BoardWidth): shape = self.shapeAt(j, Board.BoardHeight - i
