``range``
|
|
=========
|
|
|
|
Returns a list containing an arithmetic progression of integers:
|
|
|
|
.. code-block:: jinja
|
|
|
|
{% for i in range(0, 3) %}
|
|
{{ i }},
|
|
{% endfor %}
|
|
|
|
{# returns 0, 1, 2, 3 #}
|
|
|
|
When step is given (as the third parameter), it specifies the increment (or
|
|
decrement):
|
|
|
|
.. code-block:: jinja
|
|
|
|
{% for i in range(0, 6, 2) %}
|
|
{{ i }},
|
|
{% endfor %}
|
|
|
|
{# returns 0, 2, 4, 6 #}
|
|
|
|
The Twig built-in ``..`` operator is just syntactic sugar for the ``range``
|
|
function (with a step of 1):
|
|
|
|
.. code-block:: jinja
|
|
|
|
{% for i in 0..3 %}
|
|
{{ i }},
|
|
{% endfor %}
|
|
|
|
.. tip::
|
|
|
|
The ``range`` function works as the native PHP `range`_ function.
|
|
|
|

|
|

* ``low``: The first value of the sequence.
