    # 使用教程：
    # 1.下载chrome浏览器:https://www.google.com/chrome/
    # 2.查看chrome浏览器的版本号，下载对应版本号的chromedriver驱动:http://chromedriver.storage.googleapis.com/index.html
    # 3.填写chromedriver的绝对路径
    # 4.执行命令pip install selenium
    # 5.打开https://account.weibo.com/set/bindsns/bindtaobao并通过微博绑定淘宝账号密码

    if __name__ == "__main__":

        chromedriver_path = r"E:\安装包\chromedriver.exe" #改成你的chromedriver的完整路径地址
        weibo_username = "" #改成你的微博账号
        weibo_password = "" #改成你的微博密码

        a = taobao_infos()
        a.login() #登录
