#coding=utf-8

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get("http://www.youdao.com")


#向cookie的name 和value添加会话信息。
driver.add_cookie({'name':'key-aaaaaaa', 'value':'value-bbbb'})

#遍历cookies中的name 和value信息打印，当然还有上面添加的信息
for cookie in driver.get_cookies():
    print "%s -> %s" % (cookie['name'], cookie['value'])


# 下面可以通过两种方式删除cookie
# 删除一个特定的cookie
driver.delete_cookie("CookieName")
# 删除所有cookie
driver.delete_all_cookies()

time.sleep(2)
driver.close()

原来的代码修改为下列代码，可运行通过；

#coding=utf-8

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get("http://www.youdao.com")


#向cookie的name 和value添加会话信息。
driver.add_cookie({'name':'key-aaaaaaa', 'value':'value-bbbb'})

#遍历cookies中的name 和value信息打印，当然还有上面添加的信息
for cookie in driver.get_cookies():
    print ("%s -> %s" % (cookie['name'], cookie['value']))


# 下面可以通过两种方式删除cookie
# 删除一个特定的cookie
driver.delete_cookie("key-aaaaaaa")

#遍历cookies中的name 和value信息打印，当然还有上面添加的信息
for cookie in driver.get_cookies():
    print ("%s -> %s" % (cookie['name'], cookie['value']))


# 删除所有cookie
driver.delete_all_cookies()

time.sleep(2)
driver.close()

运行结果如下：
