Python 2.6.2 License 04.11.09 14:37
Python 2.6.2 license 04.11.09 14:37 Download > Releases > License Python 2.6.2 license This is the official license for the Python 2.6.2 release: A. HISTORY OF THE SOFTWARE ========================== Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands as a successor of a language called ABC. Guido remains Python's principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations (now Zope Corporation, see http://www.zope.com). In 2001, the Python Software Foundation (PSF, see http://www.python.org/psf/) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation is a sponsoring member of the PSF. All Python releases are Open Source (see http://www.opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived Year Owner GPL- from compatible?

Free Email Software Download Best Free Email Client 2021
free email software download Best Free Email Client 2021. This article is all about best free email clients and how they can help you be more productive. We also talk about Clean Email, an easy-to-use email cleaner compatible with virtually all major email services. But before we go over the best email clients for 2021, we believe that we should first explain what advantages email clients have over web-based interfaces of various email services. Clean Email. Take control of your mailbox. What Is an Email Client and Why Should I Use One? If you’re like most people, you probably check your email at least once every day. And if you’re someone whose work involves communication with customers, clients, and coworkers, the chances are that you deal with emails all the time. Even though we spend so much time writing, forwarding, and managing emails, we hardly ever pause for a moment and think about how we could improve our emailing experience. We use clunky web interfaces that are not meant for professional use, we accept outdated applications as if alternatives didn’t exist, and we settle for the default email apps on our mobile devices even though app stores are full of excellent third-party email apps. Broadly speaking, an email client is a computer program used to access and manage a user’s email. But when we use the term email client in this article, we only mean those email clients that can be installed on a desktop computer or a mobile device—not web-based email clients that are hosted remotely and are accessible only from a web browser. -

Python Qt Tutorial Documentation Release 0.0
Python Qt tutorial Documentation Release 0.0 Thomas P. Robitaille Jun 11, 2018 Contents 1 Installing 3 2 Part 1 - Hello, World! 5 3 Part 2 - Buttons and events 7 4 Part 3 - Laying out widgets 9 5 Part 4 - Dynamically updating widgets 13 i ii Python Qt tutorial Documentation, Release 0.0 This is a short tutorial on using Qt from Python. There are two main versions of Qt in use (Qt4 and Qt5) and several Python libraries to use Qt from Python (PyQt and PySide), but rather than picking one of these, this tutorial makes use of the QtPy package which provides a way to use whatever Python Qt package is available. This is not meant to be a completely exhaustive tutorial but just a place to start if you’ve never done Qt development before, and it will be expanded over time. Contents 1 Python Qt tutorial Documentation, Release 0.0 2 Contents CHAPTER 1 Installing 1.1 conda If you use conda to manage your Python environment (for example as part of Anaconda or Miniconda), you can easily install Qt, PyQt5, and QtPy (a common interface to all Python Qt bindings) using: conda install pyqt qtpy 1.2 pip If you don’t make use of conda, an easy way to install Qt, PyQt5, and QtPy is to do: pip install pyqt5 qtpy 3 Python Qt tutorial Documentation, Release 0.0 4 Chapter 1. Installing CHAPTER 2 Part 1 - Hello, World! To start off, we need to create a QApplication object, which represents the overall application: from qtpy.QtWidgets import QApplication app= QApplication([]) You will always need to ensure that a QApplication object exists, otherwise your Python script will terminate with an error if you try and use any other Qt objects. -

Gui Programming Using Tkinter
1 GUI PROGRAMMING USING TKINTER Cuauhtémoc Carbajal ITESM CEM April 17, 2013 2 Agenda • Introduction • Tkinter and Python Programming • Tkinter Examples 3 INTRODUCTION 4 Introduction • In this lecture, we will give you a brief introduction to the subject of graphical user interface (GUI) programming. • We cannot show you everything about GUI application development in just one lecture, but we will give you a very solid introduction to it. • The primary GUI toolkit we will be using is Tk, Python’s default GUI. We’ll access Tk from its Python interface called Tkinter (short for “Tk interface”). • Tk is not the latest and greatest, nor does it have the most robust set of GUI building blocks, but it is fairly simple to use, and with it, you can build GUIs that run on most platforms. • Once you have completed this lecture, you will have the skills to build more complex applications and/or move to a more advanced toolkit. Python has bindings or adapters to most of the current major toolkits, including commercial systems. 5 What Are Tcl, Tk, and Tkinter? • Tkinter is Python’s default GUI library. It is based on the Tk toolkit, originally designed for the Tool Command Language (Tcl). Due to Tk’s popularity, it has been ported to a variety of other scripting languages, including Perl (Perl/Tk), Ruby (Ruby/Tk), and Python (Tkinter). • The combination of Tk’s GUI development portability and flexibility along with the simplicity of a scripting language integrated with the power of systems language gives you the tools to rapidly design and implement a wide variety of commercial-quality GUI applications. -
Wxshapeframework: an Easy Way for Diagrams Manipulation in C++ Applications
WSEAS TRANSACTIONS on COMPUTERS Michal Bliznak, Tomas Dulik, Vladimir Vasek WXSHAPEFRAMEWORK: AN EASY WAY FOR DIAGRAMS MANIPULATION IN C++ APPLICATIONS MICHAL BLIŽŇÁK1, TOMÁŠ DULÍK2, VLADIMÍR VAŠEK3 Department of Informatics and Artificial Inteligence1, 2, Department of Automation and Control Engineering3 Faculty of Applied Informatics, Tomas Bata University Nad Stráněmi 4511, 760 05, Zlín CZECH REPUBLIC [email protected], [email protected], [email protected] Abstract: wxShapeFramework is new cross-platform software library written in C++ programming language which is suitable for creation of software applications manipulating diagrams, images and other graphical objects. Thanks to the underlying technologies such as wxWidgets toolkit and its XML-based persistent data container add-on called wxXmlSerializer it is an ideal solution for rapid and easy cross-platform visualisation software development. The paper reveals how the wxSF allows user to easily create applications able to interactively handle various scenes consisting of pre-defined or user-defined graphic objects (both vector- and bitmap-based) or GUI controls, store them to XML files, export them to bitmap images, print them etc. Moreover, thanks to applied software licence the library can be used for both open-source and commercial projects on all main target platforms including MS Windows, MacOS and Linux. Keywords: Diagram, vector, bitmap, GUI, wxWidgets, wxXmlSerializer, wxShapeFramework, wxSF, C++ 1 Introduction called shapes (including basic rectangular and elliptic shapes, line and curve shapes, polygonal shapes, static Modern software applications often need the ability to and in-place editable text, bitmap images, etc.). graphically represent various data or logical structures, information flows, processes and similar The wxSF allows to define relationship between abstract information types in the form of diagrams. -
