ForLoop

This object contains information only within a for loop. It contains the following fields:

Variable name	Object	Description	Note
first	bool	Returns true if it is the first loop iteration (false otherwise)
index	int	Contains the index of the current iteration, always starting at 1
index0	int	Same as index, but always starts at 0.
last	bool	Similar asfirst, but only true if it is the last iteration of theforloop.
length	int	Returns the number of total iterations, this will usually be the length of the processed list.
rindex	int	Like index, but counting reverse (thus the last element has index 1).
rindex0	int	Like rindex, but the last index will be 0.

Example:

{% for c in (1..4) %}
 {% if forloop.first %}
 <b>{{ c }}</b>
 {% else %}
 <i>{{ c }}</i>
 {% endif %}
{% endfor %}

Output:

<b>1</b>
<i>2</i>
<i>3</i>
<i>4</i>

{% for c in (8..12) %}
 {{ forloop.index }} - {{ c }}

Output:

1 - 8
2 - 9
3 - 10
4 - 11
5 - 12

1 - 9
2 - 10
3 - 11
4 – 12

Example:

{% for c in (0..2) %}
 {% if forloop.last %}
 LastElement
 {% else %}
 AnyElement
