我将代码中标红行改成通过id、name或class定位，都报找不到元素，请高手指点下，谢谢！
这个登录框有ifame，需要先切换ifame。 因为在你定位的用户名输入框元素节点上面有个iframe,所以要先进入找个iframe中，还有因为你的用户名和密码输入框元素ID是动态变化的，所以取ID会每次运行找不到元素，所以可以用name定位。如果你后面要定位的元素不在那个iframe下，需要跳出iframe,可以使用driver.switch_to_default_content()
参考如下：
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://mail.163.com/")
driver.find_element_by_id("lbNormal").click()
driver.switch_to_frame("x-URS-iframe")
driver.find_element_by_name("email").send_keys("username"))
driver.find_element_by_name("password").send_keys("password")
driver.find_element_by_id("dologin").click()
