注意：

    • xpath的提取不够熟练；
    • 有时候抱获取不到元素的错误，要考虑iframe，同时还要考虑是否进入到了iframe，可能上一个点击事件后，还在缓存，元素都还没有加载出来的；
    • 此案例需手动拖动验证码； ```python from selenium import webdriver from configparser import ConfigParser 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 import time import csv
