【RF库Collections测试】Get Index From List

Name:
Get Index From List
Source:
Collections <test library>
Arguments:
[ list_ | value | start=0 | end=None ]
Returns the index of the first occurrence of the `value` on the list.
The search can be narrowed to the selected sublist by the `start` and `end` indexes having the same semantics as in the `Get Slice From List` keyword. In case the value is not found, -1 is returned. The given list is never altered by this keyword.
