``range``
=========
Returns a list containing an arithmetic progression of integers:
.. code-block:: twig
{% 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):
.. code-block:: twig
{% 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``:
.. code-block:: twig
{% 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):
.. code-block:: twig
{% 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.
