WinPython is a portable distribution of the Python programming language for Windows (https://winpython.github.io).

This is the winpython Python package, not the distribution itself. It includes two main features:

WinPython Package Manager (WPPM) a graphical layer over pip, to let you install/uninstall to your WinPython distribution any standard Python package built as source (e.g. «dummypackage-2.1.zip» or «dummypackage-2.1.tar.gz») or as wheel (e.g. «dummypackage-2.1-py3-none-any.whl») WinPython build toolchain make.py is the script used to build a WinPython distribution from (almost) scratch.

• Python3 >= 3.4 (Python>= 3.7 is recommended)
• PyQt5 >= 5.6 or PySide2>=5.11 (PyQt5 >=5.12 or Pyside2 >= 5.12 is recommended)

• NSIS (for icon shortcut creations, installer can be NSIS, INNO, 7-Zip, or nothing)
• PyQt5 or Pyside2 is required to execute WinPython Control Panel/Ipython Qt and Qt related packages. if not installed, these packages will not execute.

From the source package (see section ‘Building dependencies’), you may install WinPython using the integrated setup.py script based on Python standard library distutils with the following command:

python setup.py install

Note that distutils does not uninstall previous versions of Python packages: it simply copies files on top of an existing installation. When using this command, it is thus highly recommended to uninstall manually any previous version of WinPython by removing the associated directory (‘winpython’ in your site-packages directory).

From the Python package index, you may simply install WinPython and upgrade an existing installation using pip: https://pypi.org

But the easiest way to install the last stable release of WinPython is by using an executable installer: https://winpython.github.io/

Overview

WinPython is a free open-source portable distribution of the Python programming language for Windows 8/10 and scientific and educational usage.

It is a full-featured (see our Wiki) Python-based scientific environment:

• Designed for scientists, data-scientists, and education (thanks to NumPy, SciPy, Sympy, Matplotlib, Pandas, pyqtgraph, etc.):
  • interactive data processing and visualization using Python with Spyder and Jupyter/IPython, Pyzo, IDLEX or IDLE
  • fully integrated Cython and Numba! See included example
  • connectors (cffi, odbc, rpy2, scilab2py, requests, . ) for advanced users
  • Runs out of the box(*) on any Windows 8+ with 2GB Ram (Jupyter Notebook will require a recent browser)
  • The WinPython folder can be moved to any location (**) (local, network, USB drive) with most of the application settings
  • Last WinPython version that is said to still work on Windows 7 should be WinPython64-3.8.9.0
  • You can install as many WinPython distributions as you want on the same machine: each one is isolated and self-consistent
  • These installations can be of different versions of Python (3.7/3.8/3.9. )
  • The integrated WinPython Package Manager (WPPM) helps installing, uninstalling or upgrading Python packages
  • It’s also possible to install or upgrade packages using pip from the WinPython command prompt
  • A configuration file allows you to set environment variables at runtime

  WinPython is something different from other Python Distributions (see historic motivation and concept):

  • non-invasive: WinPython lives entirely in its own directory, without any OS installation
  • customizable: add your missing packages, zip the WinPython directory and give it to your students
  • do your own version: a winpython-creator kit is made available for you

  Portable or not, the choice is yours!

  WinPython is a portable application, so the user should not expect any integration into Windows explorer during installation. However, the WinPython Control Panel allows to «register» your distribution to Windows (see screenshot below).

  

  Registering your WinPython installation will:

  • associate file extensions .py, .pyc and .pyo to Python interpreter
  • register Python icons in Windows explorer
  • add context menu entries Edit with IDLE and Edit with Spyder for .py files
  • register WinPython as a standard Python distribution (standard Python Windows installers will see WinPython in Windows registry)

  (*) For recent WinPython, Windows 8..11 users may have to install missing system DLL Microsoft Visual C++ Redistributable for Visual Studio 2017..2019 (vc_redist_x86.exe for WinPython 32bit, vc_redist_x64.exe for Winpython 64bit)

  (*) For best Winpython 2018-01 and later experience, it is recommended to have WinPython base directory path smaller than 37 characters. example: C:\Users\xxxxxxxx\Downloads\WinPython

  (**) Since WinPython 2019-02, all installers are just 7zip auto-extracts.

  WinPython

  Portable Scientific Python 2/3 32/64bit Distribution for Windows

  WinPython is a free open-source portable distribution of the Python programming language for Windows XP/7/8, designed for scientists, supporting both 32bit and 64bit versions of Python 2 and Python 3.
  Since September 2014, Developpement has moved to https://winpython.github.io/

  Features

  • Designed for regular scientific users: interactive data processing and visualization using Python with Spyder
  • Designed for advanced scientific users and software developers: Python applications development with Spyder, version control with Mercurial and other development tools (like gettext, etc.)
  • Portable: preconfigured, it should run out of the box on any machine under Windows (without any requirement) and the folder containing WinPython can be moved to any location (local, network or removable drive) with most of the application settings
  • Flexible: one can install (or should I write «use» as it’s portable) as many WinPython versions as necessary (like isolated and self-consistent environments), even if those versions are running different versions of Python (2.7, 3.x in the near future) or different architectures (32bit or 64bit) on the same machine
  • Customizable: The integrated package manager (wppm, as WinPython Package Manager) helps installing, uninstalling or upgrading Python packages
  • As WPPM may not support some packages, it’s also possible to install or upgrade packages using easy_install or pip from the WinPython command prompt
  • A configuration file allows to set environment variables at runtime
