webdriver处理循环点击

from selenium import webdriver

driver=webdriver.Chrome()
driver.get("http://toyota-oss:changeit@test3.tcom.aws.toyota.com/tcom-apps/vapi-preview/console.html")
#alert = driver.switch_to_alert()   如果是第一次打开上面的链接，就需要alert.accept(),但是从第二次之后保留了cookie就不再有弹窗
#alert.accept()
driver.maximize_window()
time.sleep(2)
print "进入toyota首页" 

#total_year=len(driver.find_element_by_id(‘year‘).find_element_by_tag_name(‘option‘))------报错：WebElement没有len属性
#print "年份的个数是"+total_year
#time.sleep(2)
#years=driver.find_element_by_id(‘year‘).find_element_by_tag_name(‘option‘)----------报错：WebElement没有循环属性
#for year in years:
#    year.click()
#    time.sleep(1)---------------本来打算用这个循环很方便的，但是总是报错，只能用下面的笨方法了！
