Overview

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

This is the wppm Python package and build toolchain repository, not the distribution itself. It includes two main features:

WinPython Package Manager (WPPM) a complementary tool to navigate provided packages, install packages from included Wheelhouse, or register WinPython. pip is the recommanded way to add or remove packages otherwise

WinPython build toolchain (historic) generate_a_winpython_distropy_meta.bat with a toml file is the toolchain used to build a WinPython distribution from (almost) scratch.

WinPython build toolchain via Github action (news of 2026-01-01) fork the project and run github action like github_workflows_build-YYYY_NN.yml for WinPython YYYY-NN relase you can modify the list of wheels with hash to your preference

WinPython set of Wheel You can get also the equivalent of the WinPython distribution by using one of the provided pylock.toml or by using provided requirements-with-hash.txt until pip does support pylock.toml files

Dependencies

• Python3 >= 3.11 to run the build toolchain

• Python3 >= 3.10 to run wppm

Requirements

• installer can be 7-Zip or nothing (just .zip-it)

• a basic github account allows you to build from your fork of this repository via github actions

Wppm build

From the source package (see section 'Building dependencies'), you may build WPPM using the following commands:

.. code-block:: bash

python -m pip install flit python -m flit build

wppm package is now build and published via github action build_wppm_prod_publish.yml

Winpython Distribution wheels installation

To only install the wheels assembled per WinPython Distribution, you may

.. code-block:: bash

python -m pip install --no-deps --require-hashes https://github.com/winpython/winpython/releases/download/16.6.20250620final/requir.64-3_13_5_0slim.txt

A pylock file is also available, when you package manager can handle it

.. code-block:: text

https://github.com/winpython/winpython/releases/download/16.6.20250620final/pylock.64-3_13_5_0slim.toml

But the easiest way to install the last stable release of WinPython is by using a zipped distribution with or without auto-extractor: https://winpython.github.io/
