역사와 라이센스

소프트웨어의 역사

파이썬은 ABC라는 언어의 후계자로서 네덜란드의 Stichting Mathematisch Centrum (CWI, https://www.cwi.nl/ 참조)의 Guido van Rossum에 의해 1990년대 초반에 만들어졌습니다. 파이썬에는 다른 사람들의 많은 공헌이 포함되었지만, Guido는 파이썬의 주요 저자로 남아 있습니다.

1995년, Guido는 Virginia의 Reston에 있는 Corporation for National Research Initiatives(CNRI, https://www.cnri.reston.va.us/ 참조)에서 파이썬 작업을 계속했고, 이곳에서 여러 버전의 소프트웨어를 출시했습니다.

In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations (now Zope Corporation; see https://www.zope.org/). In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation is a sponsoring member of the PSF.

모든 파이썬 배포판은 공개 소스입니다 (공개 소스 정의에 대해서는 https://opensource.org/를 참조하십시오). 역사적으로, 대부분 (하지만 전부는 아닙니다) 파이썬 배포판은 GPL과 호환됩니다; 아래의 표는 다양한 배포판을 요약한 것입니다.

참고

GPL과 호환된다는 것은 우리가 GPL로 파이썬을 배포한다는 것을 의미하지는 않습니다. 모든 파이썬 라이센스는 GPL과 달리 여러분의 변경을 공개 소스로 만들지 않고 수정된 버전을 배포할 수 있게 합니다. GPL 호환 라이센스는 파이썬과 GPL 하에 발표된 다른 소프트웨어를 결합할 수 있게 합니다; 다른 것들은 그렇지 않습니다.

Guido의 지도하에 이 배포를 가능하게 만든 많은 외부 자원봉사자들에게 감사드립니다.
