Python历史和许可证
该软件的历史¶
Python 由荷兰数学和计算机科学研究学会（CWI，见 https://www.cwi.nl/ ）的 Guido van Rossum 于 1990 年代初设计，作为一门叫做 ABC 的语言的替代品。尽管 Python 包含了许多来自其他人的贡献，Guido 仍是其主要作者。
1995 年，Guido 在弗吉尼亚州的国家创新研究公司（CNRI，见 https://www.cnri.reston.va.us/ ）继续他在 Python 上的工作，并在那里发布了该软件的多个版本。
2000 年五月，Guido 和 Python 核心开发团队转到 BeOpen.com 并组建了 BeOpen PythonLabs 团队。 同年十月，PythonLabs 团队转到 Digital Creations (现为 Zope Corporation；见 https://www.zope.org/)。 2001 年，Python 软件基金会 (PSF，见 https://www.python.org/psf/) 成立，这是一个专为拥有 Python 相关知识产权而创建的非营利组织。 Zope Corporation 现在是 PSF 的赞助成员。
所有的 Python 版本都是开源的（有关开源的定义参阅 https://opensource.org/ ）。历史上，绝大多数 Python 版本是 GPL 兼容的；下表总结了各个版本情况。
发布版本 | 源自 | 年份 | 所有者 | GPL 兼容？ |
|---|---|---|---|---|
0.9.0 至 1.2 | n/a | 1991-1995 | CWI | 是 |
1.3 至 1.5.2 | 1.2 | 1995-1999 | CNRI | 是 |
1.6 | 1.5.2 | 2000 | CNRI | 否 |
2.0 | 1.6 | 2000 | BeOpen.com | 否 |
1.6.1 | 1.6 | 2001 | CNRI | 否 |
2.1 | 2.0+1.6.1 | 2001 | PSF | 否 |
2.0.1 | 2.0+1.6.1 | 2001 | PSF | 是 |
2.1.1 | 2.1+2.0.1 | 2001 | PSF | 是 |
2.1.2 | 2.1.1 | 2002 | PSF | 是 |
2.1.3 | 2.1.2 | 2002 | PSF | 是 |
2.2 及更高 | 2.1.1 | 2001 至今 | PSF | 是 |
注解
GPL 兼容并不意味着 Python 在 GPL 下发布。与 GPL 不同，所有 Python 许可证都允许您分发修改后的版本，而无需开源所做的更改。GPL 兼容的许可证使得 Python 可以与其它在 GPL 下发布的软件结合使用；但其它的许可证则不行。
感谢众多在 Guido 指导下工作的外部志愿者，使得这些发布成为可能。

Modified by Jack Jansen, CWI, July 1995:
- Use binascii module to do the actual line-by-line conversion
between ascii and binary. This results in a 1000-fold speedup. The C
version is still 5 times faster, though.
- Arguments more compliant with Python standard
