selenium-查看selenium API

　　pydoc是Python自带的模块，主要用于从python模块中自动生成文档，这些文档可以基于文本呈现的、也可以生成WEB 页面的，还可以在服务器上以浏览器的方式呈现！

一、pydoc

　　1、到底什么是pydoc? ,这个是准确的解释：Documentation generator and online help system. pydoc是Python自带的模块，主要用于从python模块中自动生成文档，这些文档可以基于文本呈现的、也可以生成WEB 页面的，还可以在服务器上以浏览器的方式呈现！简而言之，就是帮你从代码和注释自动生成文档的工具。

　　2、举个栗子，我需要查看python里面open函数的功能和语法，打开cmd,输入:python -m pydoc open

　　3、-m参数：python以脚本方法运行模块

　　　　python -m pydoc open

　　　　

　　那么问题来了，这个是已经知道有这个函数，去查看它的功能，selenium里面不知道到底有多少个函数或方法，那如何查看呢？

二、启动server

　　1、打开cmd命令行，输入：python -m pydoc -p 1009

　　2、-p参数：这个表示在本机上启动服务

　　3、6666参数：这个是服务端口号，随意设置

 打开后，界面会出现一个地址：http://localhost:6666/，在浏览器中打开

三、浏览器中查看文档

　　1、在浏览器输入：http://localhost:6666/

　　2、Built-in Moudles ：这个是python自带的模块

　　

四、webdriver API

　　1、找到这个路径：C:Python33libsite-packages，点开selenium

　　2、打开的selenium>webdriver>firefox>webdriver,最终路径：http://localhost:1009/selenium.webdriver.firefox.webdriver.html
