Selenium用Python的第一个示例 (Windows系统）

1. Install Python (https://www.python.org/)，download the latest Python version

2. Configure environment variables. (Example), I installed Python under /installation folder with Python 3.5.2. The path set is as follows:

   D:installationPython3.5.2;D:installationPython3.5.2Scripts;

3. Install pip (you may search related steps from internet to install)

   (locate to /Scripts folder, to perform easy_install pip command

4. If installation success, type pip command to check

5. Install selenium. To perform command pip install -U selenium

6. Till now, Python and Selenium have been installed successfully, then you are able to create Python code to drive browser. Here we using Edge browser to check.

7. Before you do, you need to download Edge driver (https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/) and put it on Python installation foloder (D:installationPython3.5.2)

   650) this.width=650;" title="driver.JPG" src="/upload/getfiles/default/2022/11/10/20221110033002984.jpg" />

8. from selenium import webdriver driver = webdriver.Edge() driver.get("https://www.baidu.com") print("width:600,height:800") driver.set_window_size(600,800) driver.quit()

1. 查看一下源代码，看看上面这段代码是如何工作的

   首先在 lib 目录下有一个 site-packages 的文件夹，下面有一个 selenium 的目录

D:installationPython3.5.2Libsite-packagesselenium，selenium目录下有一个webdriver的目录，里面是支持的各个浏览器

650) this.width=650;" title="1.png" src="/upload/getfiles/default/2022/11/10/20221110033003274.jpg" />

这个是 __init__.py 的代码

650) this.width=650;" title="2.png" src="/upload/getfiles/default/2022/11/10/20221110033003553.jpg" />

从当前目录导入 WebDriver 类，然后给它一个别名，如 Edge （对应的代码调用就是 webdriver.Edge(), 不然就应当写成 webdriver.WebDriver())

打开 WebDriver 类的代码，如图所示

650) this.width=650;" title="3.png" src="/upload/getfiles/default/2022/11/10/20221110033003894.jpg" />

有两个方法，一个是初始 __init__ ，一个是 quit ，调用 Edge() 后就执行 __init__ 方法，最后关闭 edge 时调用 quit() 方法
