1 安裝python

2 安裝Selenium

Python3.x安裝後就預設就會有pip（pip.exe預設在python的Scripts路徑下），使用pip安裝selenium：

pip install selenium

因我已安裝selenium，不可重複安裝。 可使用以下命令檢視是否安裝成功：

pip show selenium

3 安裝最新版谷歌和下載chromedriver

4 測試

from selenium import webdriver
 
browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')
 

第二行程式碼會開啟谷歌 第三行會開啟百度
