`range`

¶

Returns a list containing an arithmetic progression of integers:

1 2 3 4 5 | ```
{% for i in range(0, 3) %}
{{ i }},
{% endfor %}
{# outputs 0, 1, 2, 3, #}
``` |

When step is given (as the third parameter), it specifies the increment (or decrement for negative values):

1 2 3 4 5 | ```
{% for i in range(0, 6, 2) %}
{{ i }},
{% endfor %}
{# outputs 0, 2, 4, 6, #}
``` |

Note

Note that if the start is greater than the end, `range`

assumes a step of
`-1`

:

1 2 3 4 5 | ```
{% for i in range(3, 0) %}
{{ i }},
{% endfor %}
{# outputs 3, 2, 1, 0, #}
``` |

The Twig built-in `..`

operator is just syntactic sugar for the `range`

function (with a step of `1`

, or `-1`

if the start is greater than the end):

1 2 3 | ```
{% for i in 0..3 %}
{{ i }},
{% endfor %}
``` |

Tip

The `range`

function works as the native PHP range function.

## Arguments¶

`low`

: The first value of the sequence.`high`

: The highest possible value of the sequence.`step`

: The increment between elements of the sequence.
