处理下拉列表，需要用到Selenium中的一个工具类Select，以下是常用方法/属性：
| 方法/属性 | 方法/属性描述 |
|---|
| select_by_value() | 根据值选择 | | select_by_index() | 根据索引选择 | | select_by_visible_text | 根据文本选择 | | deselect_by_value | 根据值反选 | | deselect_by_index | 根据索引反选 | | deselect_by_visible_text | 根据文本反选 | | deselect_all | 反选所有 | | all_selected_options | 所有选中选项 | | first_selected_option | 第一个选择选项 |
