Unix and Linux users

Binaries are not provided for any of the various versions of Linux or Unix or for any platforms they may be running on. Please use the the Mercurial repository or the old Subversion repository to compile your own copy of Stackless Python. The directory structure follows that of the main Python repository.

Mac OS X users

Microsoft Windows users

If you do not wish to compile Stackless Python yourself, we provide two ways in which you can install a precompiled version. The most straightforward way is using one of the provided installers, while the less straightforward way is converting an existing Python installation into a Stackless one.


Binary Snapshots

If you are downloading one of these binary snapshots, you are intending to create a Stackless Python installation through modifying a standard Python installation. You may do so in this way:

  1. Download a standard Python installer.
  2. Download the binary snapshots from those which are listed below, which has the same version as the standard Python installer you downloaded.
  3. Run the standard Python installer.
  4. Extract the binary snapshot archive into the installed Python director:

Microsoft Windows users - Earlier versions of Python

Complete installations of Stackless Python are not provided. Instead the dlls that comprise the Python runtime with the Stackless changes built in, are. These should replace the files with the same names in your Python installation and are all that is needed for you to obtain a working version of Stackless Python.

There are two ways which you can do this:

  1. Place the Stackless dlls in your PATH before the standard ones.
  2. Directly replace the dlls in your Python installation. If you installed an official installer based Python installation from, you can find the dlls in your WINDOWS directory under the system32 sub-directory. In Windows XP Professional, this will be WINDOWS\system32. Even if the WINDOWS directory is named differently in your version of Microsoft Windows, they will most likely be installed in the system32 sub-directory within it.
