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
generate_a_winpython_distro.bat and make.py are the toolchain used to
build a WinPython distribution from (almost) scratch.

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 >= 3.10

Requirements

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

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

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/
