注：Python版本3.6

開啟瀏覽器，百度頁面

#coding=utf-8
from selenium import webdriver
driver=webdriver.Chrome()  #呼叫chrome瀏覽器
driver.get('https://www.baidu.com')
print (driver.title)
#driver.quit()

不同瀏覽器所需外掛不同，按手頭的資源情況，選擇合適的測試環境。

Chrome

driver=webdriver.Chrome()  #呼叫chrome瀏覽器

IE

driver=webdriver.Ie()
 

報錯：

IE還需要其它的安全配置，具體需要時自行百度

FireFox
