# for: visiting each item

[Syntax and values](README.md)

```text
for color in ["red", "green", "blue"]:
    say color

for character in "Pliro 🐢":
    say character
```

`for` accepts a `List` or `Text`. Text iteration yields one [Unicode](../concepts/unicode.md) code point
as `Text` per iteration. Maps are not directly iterable.

The loop variable exists only in the loop body. Every iteration receives a
fresh child scope.

The iterable expression is evaluated once. A list's top-level element sequence
is snapshotted before iteration, so replacing a list cell during the loop does
not replace a later scalar value already selected for iteration. Nested list or
map elements retain normal shared collection storage.

## Example

```pliro
# language: en
for item in [10, 20, 30]:
    say item
for character in "🐢ab":
    say character
```
