Эта Markdown-версия страницы предназначена для работы с LLM: вставьте её в ChatGPT, Claude или Cursor.45---67# История и лицензия89## История программного обеспечения1011Python был создан в начале 1990-х годов Гвидо ван Россумом в Stichting Mathematisch Centrum (CWI, см. [https://www.cwi.nl](https://python-all.ru/3/license.html)) в Нидерландах как преемник языка ABC. Гвидо остаётся основным автором Python, хотя включает множество вкладов от других.1213В 1995 году Гвидо продолжил работу над Python в Корпорации национальных исследовательских инициатив (CNRI, см. [https://www.cnri.reston.va.us](https://python-all.ru/3/license.html)) в Рестоне, Виргиния, где выпустил несколько версий программного обеспечения.1415В мае 2000 года Гвидо и основная команда разработчиков Python перешли в BeOpen.com, чтобы сформировать команду BeOpen PythonLabs. В октябре того же года команда PythonLabs перешла в Digital Creations, которая стала Zope Corporation. В 2001 году была основана Python Software Foundation (PSF, см. [https://www.python.org/psf/](https://python-all.ru/3/license.html)), некоммерческая организация, созданная специально для владения интеллектуальной собственностью, связанной с Python. Zope Corporation была спонсирующим членом PSF.1617Все выпуски Python являются открытым исходным кодом (см. [https://opensource.org](https://python-all.ru/3/license.html) для определения открытого кода). Исторически большинство, но не все, выпуски Python были также совместимы с GPL; приведённая ниже таблица суммирует различные версии.1819| Версия | Происходит от | Год | Владелец | Совместим с GPL? (1) |20| --- | --- | --- | --- | --- |21| 0.9.0 – 1.2 | н/д | 1991-1995 | CWI | да |22| 1.3 – 1.5.2 | 1.2 | 1995-1999 | CNRI | да |23| 1.6 | 1.5.2 | 2000 | CNRI | нет |24| 2.0 | 1.6 | 2000 | BeOpen.com | нет |25| 1.6.1 | 1.6 | 2001 | CNRI | да (2) |26| 2.1 | 2.0+1.6.1 | 2001 | PSF | нет |27| 2.0.1 | 2.0+1.6.1 | 2001 | PSF | да |28| 2.1.1 | 2.1+2.0.1 | 2001 | PSF | да |29| 2.1.2 | 2.1.1 | 2002 | PSF | да |30| 2.1.3 | 2.1.2 | 2002 | PSF | да |31| 2.2 и выше | 2.1.1 | 2001 – настоящее время | PSF | да |3233> **Примечание**34>35> 1. Совместимость с GPL не означает, что мы распространяем Python под лицензией GPL. Все лицензии Python, в отличие от GPL, позволяют распространять модифицированную версию без публикации ваших изменений как открытого исходного кода. Лицензии, совместимые с GPL, позволяют объединять Python с другим программным обеспечением, выпущенным под GPL; остальные – нет.36> 2. По словам Ричарда Столлмана, версия 1.6.1 несовместима с GPL, поскольку её лицензия содержит оговорку о выборе права. Однако, по заявлению CNRI, юрист Столлмана сообщил юристу CNRI, что 1.6.1 «не несовместима» с GPL.3738Благодарим многочисленных внешних волонтёров, работавших под руководством Гвидо, которые сделали возможными эти релизы.3940## Условия доступа к Python или его использования4142Программное обеспечение Python и документация лицензированы в соответствии с Python Software Foundation License Version 2.4344Начиная с Python 3.8.6, примеры, рецепты и другой код в документации лицензируются двойной лицензией: PSF License Version 2 и [лицензия BSD с нулевым количеством условий](https://python-all.ru/3/license.html#bsd0).4546Некоторое программное обеспечение, включённое в Python, распространяется под другими лицензиями.
