Selenium使用lambda定义Firefox驱动时报function对象无get属性错误求助

• 核心错误：你将self.driver赋值为未调用的lambda函数，而非webdriver实例对象，调用get方法时自然会抛出函数对象无该属性的异常。
• 其他连带问题：
  1. login方法缩进错误，被定义在__init__构造函数内部，属于局部函数，无法作为类方法被外部调用
  2. self.comentario赋值时末尾拼接了, self.discord，最终为元组类型而非字符串，后续输入到文本框会报错
  3. 给登录输入框传值时直接传递StringVar对象，没有调用.get()方法获取实际输入的文本
  4. 代码中使用的find_element_by_css_selector为Selenium高版本已废弃的语法

1. 去掉lambda写法，点击登录后再实例化webdriver，避免程序启动时就打开闲置浏览器
2. 调整login方法的缩进，使其成为Bot类的公共成员方法
3. 修正self.comentario的字符串拼接逻辑，统一为字符串类型
4. 所有StringVar取值都调用.get()方法，废弃的Selenium语法替换为标准的find_element写法
