- What is the Python Software Foundation?
- ---------------------------------------
- The Python Software Foundation is an independent non-profit
- organization that holds the copyright on Python versions 2.1 and
- newer. The PSF's mission is to advance open source technology related
- to the Python programming language and to publicize the use of Python.
- The PSF's home page is at https://www.python.org/psf/.
- Donations to the PSF are tax-exempt in the US. If you use Python and
- find it helpful, please contribute via the PSF donation page.
- Are there copyright restrictions on the use of Python?
- ------------------------------------------------------
- You can do anything you want with the source, as long as you leave the
- copyrights in and display those copyrights in any documentation about
- Python that you produce. If you honor the copyright rules, it's OK to
- use Python for commercial use, to sell copies of Python in source or
- binary form (modified or unmodified), or to sell products that
- incorporate Python in some form. We would still like to know about
- all commercial use of Python, of course.
- See the PSF license page to find further explanations and a link to
- the full text of the license.
- The Python logo is trademarked, and in certain cases permission is
- required to use it. Consult the Trademark Usage Policy for more
- information.
