练习1：使用数据驱动的方式，登录多个邮箱账号
login_info.txt:
youxiang_99@163.com,XXXX
youxiang_100@163.com,XXXX

main.py:
from selenium import webdriver
import time

with open("login_info.txt") as fp:
    for data in fp:
        username_data,password_data = data.strip().split(",")
        driver=webdriver.Ie(executable_path="c:\\IEDriverServer")

        driver.get("http://mail.163.com")
        time.sleep(5)
        frame=driver.find_element_by_xpath("//iframe[@id='x-URS-iframe']")

        driver.switch_to_frame(frame)
        username=driver.find_element_by_xpath("//input[@placeholder='邮箱帐号或手机号' and @name='email']")
        password=driver.find_element_by_xpath("//input[@placeholder='密码']")
        submit_button=driver.find_element_by_xpath("//a[@id='dologin']")
        username.clear()
        password.clear()
        username.send_keys(username_data)
        password.send_keys(password_data)
        submit_button.click()
        time.sleep(15)
        driver.switch_to_default_content()
        assert u"退出"  in driver.page_source
        driver.quit()
