Overview

WinPython is a free open-source portable distribution of thePython programming language for Windows 10/11(***) and scientific and educational usage.

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

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

Portable or not, the choice is yours!

WinPython is a portable application, so the user should not expect any integration into Windows explorer duringinstallation. However, theWinPython Control Panel orWinPython Package Manager allows to "register" your distribution to Windows (see screenshot below).

Registering your WinPython installation will:

That is exactly what the official Python installer would do to your machine: in other words, you can have it both ways!

(*) For recent WinPython, Windows 8..11 users may have to install missing system DLLMicrosoft 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 up to 2020-02 may still work for Windows 7 (report of 2021-02 working for some case do also exist)
