Python 是一种面向对象、解释型计算机程序设计语言，其源代码同样遵循 GPL(GNU General Public License)协议。Python语法简洁而清晰，具有丰富和强大的类库。由于Python语言的简洁、易读以及可扩展性，已成为广大攻城狮最受欢迎的程序设计语言之一。其在设计上坚持了清晰划一的风格，其编程语法有很强的限制性（缩进等），对没有良好编程习惯的攻城狮来说是一种局限，但对源码的规范和后期的维护却有着深远的益处。同时，Python 一种高级动态编程语言，是完全面向对象的语言。函数、模块、数字、字符串都是对象。并且完全支持继承、重载、派生、多继承，有益于增强源代码的复用性。Python支持重载运算符和动态类型。（更多 Python 的特性请自行联系 度娘 或者 谷大爷，谢谢！）
此文主要讲述 Python + Selenium 在 Mac OX 下的环境配置，敬请各位小主参阅。若有不足之处，敬请大神指正，非常感谢！
一、安装 Python
一般 MacOX 中自带，无需安装。若未安装，请自行到 Python 官网下载安装。官网链接：https://www.python.org/
执行命令 python -V 查看系统安装的 Python 版本，系统输出如下所示：
Python 2.7.6
二、安装 Python 基础包工具 setuptools
其对应的网址链接为：https://pypi.python.org/pypi/setuptools/
在控制台输入命令：curl https://bootstrap.pypa.io/ez_setup.py -o - | python，（需要联网）
asrh-3.2# curl https://bootstrap.pypa.io/ez_setup.py -o - | python

三、安装Python 安装包管理工具 pip
pip 对应的网址为：https://pypi.python.org/pypi/pip
pip 自 python 2.7.9（含）和 Python 3.4（含）之后的版本中均已经包含了 pip，若是您安装了此版本，则无需再次安装 pip，请知悉！
下载 get-pip.py 对应链接为：https://bootstrap.pypa.io/get-pip.py ，下载完后执行命令 python get-pip.py，将会安装 pip，出现以下信息后，说明成功安装 pip。
asrh-3.2# python get-pip.py
/tmp/tmppUtgRW/pip.zip/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.

若是安装 pip 时未安装 setuptools，get-pip.py 也会安装 setuptools，无需担心。
pip 常用示例：
// 升级 setuptools pip install -U setuptools // 升级 pip pip insatll -U pip
四、安装 selenium
执行命令 pip install -U selenium，会联网下载最新的 selenium 并安装到系统，出现如下信息说明 selenium 安装成功。
asrh-3.2# pip install -U selenium

至此， PySe-001-基础环境配置（MacOX） 顺利完结，希望此文能够给初学 Python 2.7.6 + Selenium 2.47.1 的您一份参考。
最后，非常感谢亲的驻足，希望此文能对亲有所帮助。热烈欢迎亲一起探讨，共同进步。非常感谢！ ^_^
