Python是一种广泛使用的高级编程语言，但随着时间的推移，语言本身也在不断地发展。在Python的发展历程中，2.x和3.x版本的分歧变得越来越大，尤其是在Python 2.7和Python 3.0之间。许多开源项目和企业级应用需要同时支持这两个版本，这就导致了维护多个代码库和双版本部署的复杂性。因此，为了简化跨版本的代码兼容性问题，开发者布雷特·斯拉特金（Brett Slatkin）创建了six库。

SIX是用于python2与python3兼容的库。它存在的目的是为了拥有无需修改即可在Python 2和Python 3上同时工作的代码。话虽这么说，但是这并不代表在Python 3中引用该库就可以轻松地跑Python 2的代码。实际上，SIX是重定义了在python2和3中有差异的函数，例如dict的获取全部键值函数：在Python2中是.iterkeys()在Python3中是.keys()...

在 Python 社区中，随着 Python 2 的逐渐退出舞台，许多项目需要同时兼容 Python 2 和 Python 3。为了简化这一任务，Python 社区开发了一个名为 six 的工具库，它提供了一组函数和工具，使得编写兼容 Python 2 和 Python 3 的代码变得更加容易。本文将深入探讨 Python six 库的功能、使用方法以及实际应用场景，并附上丰富的示例代码。

针对python2和python3中unbound function的支持不同，在python2中存在unbound function，在python3中不存在unbound function。这里针对python2和python3中的文本字符进行了区分：在python2中，使用的文本字符的类型为unicode；这里针对python2和python3中各自的string类型进行了区分：在python2中，使用的为basestring；针对python2和python3中的区别，获取func中的默认元组。
