Selenium3+python3自动化（二十）--查看selenium API

前言

前面都是通过官网或他人博客学些selenium，介绍的一些selenium api使用方法，那么selenium的api到底有多少呢？本篇介绍如何查看完整的selenium api

pydoc是Python自带的模块，主要用于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

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 6666

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:7777/，输入b，在浏览器中直接打开

三、浏览器查看文档

1.发现浏览器自动打开：http://localhost:7777/

2.Built-in Moudles:这个是python自带的模块

四、webdriver API

1.找到这个路径：python37\lib\site-packages，点开selenium

2.打开selenium>webdriver>chrome>webdriver,最终路径：http://localhost:7777/selenium.webdriver.chrome.webdriver.html

3.最终看到的这些就是selenium的webdriver API帮助文档啦
