from Selenium Import webdriver
 Import Time 
Driver = webdriver.Chrome () # instantiated, and opened to specify the Firefox browser 

# access Baidu Home 
first_URL = " http://www.baidu .com " 
driver.get (first_URL) #
 Print ( " now access% S " % first_URL) 

the time.sleep ( 1 ) 

# access news page 
second_URL = " http://news.baidu.com " 
Print ( " now access% S " %second_URL) 
driver.get (second_URL) 

the time.sleep ( 1 ) 

# return (back) to the Baidu home page 
print ( " the Back to% S " % first_URL) 
driver.back () 

the time.sleep ( 1 ) 

# forward to the news page
