<section id="history-of-the-software">
<h2>该软件的历史<a class="headerlink" href="#history-of-the-software" title="永久链接至标题"></a></h2>
<p>Python 由荷兰数学和计算机科学研究学会（CWI，见 <a class="reference external" href="https://www.cwi.nl/">https://www.cwi.nl/</a> ）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。</p>
<p>1995 年，Guido 在弗吉尼亚州的国家创新研究公司（CNRI，见 <a class="reference external" href="https://www.cnri.reston.va.us/">https://www.cnri.reston.va.us/</a> ）继续他在 Python 上的工作，并在那里发布了该软件的多个版本。</p>
<p>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 <a class="reference external" href="https://www.zope.org/">https://www.zope.org/</a>)。 2001 年，Python 软件基金会 (PSF，见 <a class="reference external" href="https://www.python.org/psf/">https://www.python.org/psf/</a>) 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。</p>
<p>所有的 Python 版本都是开源的（有关开源的定义参阅 <a class="reference external" href="https://opensource.org/">https://opensource.org/</a> ）。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。</p>

<div class="admonition note">
<p class="admonition-title">注解</p>
<p>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。</p>
</div>
<p>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。</p>

version is still 5 times faster, though.
- Arguments more compliant with Python standard
