insert inserts a new element into a string or list.
Arguments
| Parameter Name | Default Value | Meaning |
|---|---|---|
| self | string or list | sequence to insert into |
| index | number | position at which to insert the new item |
| value | any | element to insert at the specified index |
Usage Notes
In the case of a list, the list is both modified in place and returned. Strings are immutable, so in that case the original string is unchanged, but a new string is returned with the value inserted.
Example
"Hello".insert(2, 42) // returns "He42llo"
