Python Software Foundation

Python Software Foundation is a 501(c)(3) non-profit organization devoted to the Python programming language, launched on March 6, 2001. The foundation serves as the steward of Python, holding intellectual property rights for Python releases 2.1 and later, and protecting Python-related trademarks including the Python name, two-snakes logo, and terms like PyLadies and PyCon. The PSF is responsible for developing and distributing the core Python distribution, made available to the public free of charge, including the Python language itself, standard libraries, documentation, installers, source code, educational materials, and associated tools. The organization operates as the primary point of contact for organizations wishing to work with, support, or sponsor Python development, providing a global structure for coordinating work, donations, and sponsorships. The PSF runs PyCon US, the largest and longest-running annual Python community conference, which serves as their flagship event attracting over 3,000 attendees from around the world. Beyond PyCon US, the foundation supports and encourages Python events worldwide through their grants program, having provided over $300,000 annually to Python groups globally. The PSF maintains critical community infrastructure including PyPI (Python Package Index), python.org, and mail.python.org, while also funding special projects like the CPython Developer in Residence program. The foundation operates with a small core staff and relies on a global network of volunteers, maintaining five tiers of membership including Basic, Supporting, Managing, Contributing members, and Fellows. Incorporated in Delaware and headquartered in Beaverton, Oregon, the PSF has received significant recognition including the 2005 Computerworld Horizon Award for cutting-edge technology and a $1.5 million donation from Anthropic in January 2026.
