# Finding an item by its position

[Syntax and values](README.md)

An index tells Pliro which item you want. List and text positions start at zero, so the first item has index 0.

```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.

Text supports zero-based read-only indexing by [Unicode](../concepts/unicode.md) code point:

```text
let mascot = "🐢Pliro"
say mascot[0]  # 🐢
```

Text cannot be changed through `set`.

## Example

```pliro
# language: en
let items = [10, 20]
say items[0]
say "🐢ab"[0]
let player = {"score": 12}
say player["score"]
```
