 3 
 4         If more than one value is given for a single-selection list, the last
 5         value will be selected. If the target list is a multi-selection list,
 6         and `*items` is an empty list, all values of the list will be selected.
 7 
 8         *items try to select by value then by label.
 9 
10         It‘s faster to use ‘by index/value/label‘ functions.
11 
12         An exception is raised for a single-selection list if the last
13         value does not exist in the list and a warning for all other non-
14         existing items. For a multi-selection list, an exception is raised
15         for any and all non-existing values.
16 
17         Select list keywords work on both lists and combo boxes. Key attributes for
18         select lists are `id` and `name`. See `introduction` for details about
19         locating elements.

方法名:select_from_list(self, locator, *items)

相似方法:

公共方法 选中所传入items,如果给了多个值,并且是single-selection list,则最后一值会被选中;如果是 multi-selection list,并且items为空,则所有options都会被选中

接收参数:locator,*items(labels/values)

26行:使用_get_select_list(self, locator)方法,返回Select对象
