# List: keeping items in order

[Syntax and values](README.md)

A list keeps several values together in a chosen order. It can hold scores, player names, or other items.

```text
let scores = [10, 20, 30]
let empty = []
let mixed = [1, "two", true, none]
```

Lists preserve order and may contain any value. A trailing comma is accepted.
Indexes are zero-based, non-negative whole numbers:

```text
say scores[0]
set scores[1] = 25
```

An index must already be in range. Lists have fixed length because there is no
append operation in the current standard library. `left + right` creates a new
concatenated list.

## Example

```pliro
# language: en
let items = [10, 20]
set items[0] = 15
let more = items + [30]
say items, more
```
