Python Special Interest Groups


There are a number of Special Interest Groups (SIGs) for focused collaborative efforts to develop, improve, or maintain specific Python resources. Each SIG has a charter, a coordinator, a mailing list, and a directory on the Python website. SIG membership is informal, defined by subscription to the SIG's mailing list. Anyone can join a SIG, and participate in the development discussions via the SIG's mailing list.

Below is the list of currently active Python SIGs, with links to their resources. The link in the first column directs you to the SIG's home page: a page with more information about the SIG. The links in the "Info" column direct you to the SIG's archives, and to the SIG's Mailman page, which you can use to subscribe or unsubscribe yourself and to change your subscription options.

The SIG mailing lists are managed by GNU Mailman, a web-based interface for mailing lists written in Python.


There is also a list of retired SIGs; these SIGs existed in the past but are no longer active. Their archives and home pages are retained. A retired SIG can be revived, using the same criteria as for creating a new SIG.

Regional Groups

There are also local Python User Groups, organized by region rather than by special interest.


All SIG mailing lists are archived.
