WPyPy is an alternative implementation of the Python programming language to CPython. PyPy often runs faster than CPython because PyPy is a just-in-time compiler while CPython is an interpreter. Most Python code runs well on PyPy except for code that depends on CPython extensions, which either does not work or incurs some overhead when run in PyPy. Internally, PyPy uses a technique known as meta-tracing, which transforms an interpreter into a tracing just-in-time compiler. Since interpreters are usually easier to write than compilers, but run slower, this technique can make it easier to produce efficient implementations of programming languages. PyPy's meta-tracing toolchain is called RPython.
WAnaconda is a distribution of the Python and R programming languages for scientific computing, that aims to simplify package management and deployment. The distribution includes data-science packages suitable for Windows, Linux, and macOS. It is developed and maintained by Anaconda, Inc., which was founded by Peter Wang and Travis Oliphant in 2012. As an Anaconda, Inc. product, it is also known as Anaconda Distribution or Anaconda Individual Edition, while other products from the company are Anaconda Team Edition and Anaconda Enterprise Edition, both of which are not free.
WGNU Bazaar is a distributed and client–server revision control system sponsored by Canonical.
WCelery is an open source asynchronous task queue or job queue which is based on distributed message passing. While it supports scheduling, its focus is on operations in real time.
WThe Disordered Structure Refinement program (DSR), written by Daniel Kratzert, is designed to simplify the modeling of molecular disorder in crystal structures using SHELXL by George M. Sheldrick. It has a database of approximately 120 standard solvent molecules and molecular moieties. These can be inserted into the crystal structure with little effort, while at the same time chemically meaningful binding and angular restraints are set. DSR was developed because the previous description of disorder in crystal structures with SHELXL was very lengthy and error-prone. Instead of editing large text files manually and defining restraints manually, this process is automated with DSR.
Weric is a free integrated development environment (IDE) used for computer programming. Since it is a full featured IDE, it provides by default all necessary tools needed for the writing of code and for the professional management of a software project.
WGrok is an open-source web framework based on Zope Toolkit technology. The project was started in 2006 by a number of Zope developers. Its core technologies are also used in other Zope-based projects.
WIDLE is an integrated development environment for Python, which has been bundled with the default implementation of the language since 1.5.2b1. It is packaged as an optional part of the Python packaging with many Linux distributions. It is completely written in Python and the Tkinter GUI toolkit.
WJinja is a web template engine for the Python programming language. It was created by Armin Ronacher and is licensed under a BSD License. Jinja is similar to the Django template engine but provides Python-like expressions while ensuring that the templates are evaluated in a sandbox. It is a text-based template language and thus can be used to generate any markup as well as source code.
WJuju is an open source application modeling tool developed by Canonical Ltd. Juju focuses on reducing the operation overhead of today's software by facilitating quickly deploying, configuring, scaling, integrating, and performing operational tasks on a wide choice of public and private cloud services along with bare metal servers and local container based deployments.

WNeil Modular Tracker is a free software project to create a functional Jeskola Buzz clone for Linux, based on an earlier, currently unmaintained program called Aldrin. Maintained by Vytautas Jančauskas, it has ongoing activity as of 2011. The name is a wordplay on Buzz Aldrin and Neil Armstrong.
WNINJA-IDE, is a cross-platform integrated development environment (IDE) designed to build Python applications.
WNmap is a free and open-source network scanner created by Gordon Lyon. Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses.
Wpip is a package-management system written in Python used to install and manage software packages. It connects to an online repository of public and paid-for private packages, called the Python Package Index.
WPyomo is a collection of Python software packages for formulating optimization models.
WPyScripter is a free and open-source software Python integrated development environment (IDE) for Windows. It is built in Object Pascal and Python.
WPyspread is a non-traditional spreadsheet. Cells in pyspread's grid accept expressions in the Python programming language. A cell can return any Python object, which allows calculations with vectors, matrices, fractions, arbitrary precision numbers and symbols. Therefore, pyspread follows an approach that is similar to the spreadsheet SIAG from Siag Office.
Wqutebrowser is a web browser for Linux, Windows, and macOS operating systems with Vim-style key bindings and a minimal GUI. It is keyboard-driven and is inspired by similar software such as Vimperator and dwb. It uses DuckDuckGo as the default search engine. Qutebrowser is included in the native repositories of Linux distributions such as Fedora and Arch Linux.
WSource Filmmaker is a 3D computer graphics software toolset used for creating animated films, utilizing the Source game engine. The tool, created by Valve, was used to create over 50 animated shorts for its Source games, including Team Fortress 2, the Left 4 Dead series, and Half-Life 2. On June 27, 2012, Valve released a free open beta version of the SFM to the gaming community via its Steam service.
WSpyder is an open source cross-platform integrated development environment (IDE) for scientific programming in the Python language. Spyder integrates with a number of prominent packages in the scientific Python stack, including NumPy, SciPy, Matplotlib, pandas, IPython, SymPy and Cython, as well as other open source software. It is released under the MIT license.
WSublime Text is a shareware cross-platform source code editor with a Python application programming interface (API). It natively supports many programming languages and markup languages, and functions can be added by users with plugins, typically community-built and maintained under free-software licenses.
