无法运行代码并打印结果，使用xpath和webdriver通过以下代码点击下拉菜单

 from selenium import webdriver
 from selenium.webdriver.common.by import By
 from selenium.webdriver.support.ui import WebDriverWait
 from selenium.webdriver.support import expected_conditions as EC

 driver = webdriver.Firefox()
 driver.get('URL')
 driver.maximize_window()
 wait = WebDriverWait(driver,40)
 wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR,'div.combobox-input-wrap a[data-value="rbAll"]'))).click()
 wait.until(EC.element_to_be_clickable((By.XPATH,'//div[@class="droplist-item"]/a[contains(.,"Headline Category")]'))).click()
 wait.until(EC.element_to_be_clickable((By.XPATH,'//div[@id="rbAfter2006"]//div[@class="combobox-input-wrap"]/a[contains(.,"ALL")]'))).click()
 wait.until(EC.element_to_be_clickable((By.XPATH,'//div[@class="droplist-group"]//ul[@class="droplist-items"]//li/a[contains(.,"Announcements and Notices")]'))).click()
 ele=wait.until(EC.presence_of_element_located((By.XPATH,'//div[@class="droplist-group droplist-submenu level2"]//ul//li/a[contains(.,"New Listings (Listed Issuers/New Applicants)")]')))
 ele.location_once_scrolled_into_view
 ele.click()
 ele2=wait.until(EC.presence_of_element_located((By.XPATH,'//div[@class="droplist-group droplist-submenu level3"]//ul//li/a[contains(.,"Allotment Results")]')))
 ele2.location_once_scrolled_into_view
 ele2.click()

 html = driver.page_source
 print html

运行时的错误日志如下所示。

   driver = webdriver.Firefox()
