``range`` ========= Returns a list containing an arithmetic progression of integers: .. code-block:: jinja {% 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): .. code-block:: jinja {% for i in range(0, 6, 2) %} {{ i }}, {% endfor %} {# outputs 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. Arguments --------- * ``low``: The first value of the sequence. * ``high``: The highest possible value of the sequence. * ``step``: The increment between elements of the sequence. .. _`range`: http://php.net/range
