Remove elements based on index
Overview
The remove index deluge task removes an element from a list based on a specified index, and returns that element.
Index refers to the position of elements in a list, and it starts from 0. So the index of the first element in the list will be 0, of the second element will be 1, and so on.
Syntax
<variable> = <list_variable>.remove(<index>);
| Parameter | Description |
|---|---|
<variable> (optional) | Variable which will contain the returned value. |
| <list_variable> | The list variable from which an element has to be removed and returned. Data type is List. |
| <index> | Index of the element which needs to be removed from the list and returned. Value should not be a negative number. If a negative number is specified, or the index is not found, a runtime error will be encountered. Value should not exceed the list size. Ideally, this limit will be list size minus 1, since index starts from 0. Data type is Number. |
