item 1.0

item index list

item index string

On lists, reports the value of the item in the given list with the given index.

On strings, reports the character in the given string at the given index.

Note that the indices begin from 0, not 1. (The first item is item 0, the second item is item 1, and so on.)

If index is fractional, it will be rounded down to the nearest integer (4.5 becomes 4, 10.9 becomes 10).

;; suppose mylist is [2 4 6 8 10]
show item 2 mylist
=> 6
show item 3 "my-shoe"
=> "s"
