#下拉框在web页面上非常常见，对于下拉框的处理采用二次定位的方法进行元素定位：首先定位到下拉框，然后再定位下拉框的具体元素
from selenium import webdriver
import os
import time
driver = webdriver.Firefox()
file_path = ‘file:///‘+os.path.abspath(‘drop_down.html‘)
driver.get(file_path)
#首先定位到下拉框
drop_down = driver.find_element_by_id(‘ShippingMethod‘)
# 再点击下拉框到的选项
drop_down.find_element_by_xpath(‘//option[@value=‘10.69‘]‘).click()
time.sleep(5)
driver.quit()
