Selenium 使您可以自动化 Web 浏览器。 Selenium 是一个 Python 模块。 除了 Python 模块之外，您还需要 Web 驱动程序。
|
|||
|
|
|
|||
|
|
通过 Python，您可以控制 Firefox，Chrome，Internet Explorer，Edge 和许多其他浏览器。 您可以打开一个新的 URL，单击按钮等等。
|

|

|

### Selenium 浏览器
|
|||
|
|
|
|||
|
|
下面的 Selenium 浏览器代码启动了多个 Web 浏览器。 他们打开一个网站，然后关闭浏览器。 必须安装 Web 驱动程序才能起作用。

|

|
```py
