How to increment a variable on a for loop in jinja template?

Question

I would like to do something like:

variable p is from test.py which is a list [\'a\',\'b\',\'c\',\'d\']

{% for i in p %}
{{variable++}}
{{variable}}

After 2.10, to solve the scope problem, you can do something like this:

{% set count = namespace(value=0) %}
{% for i in p %}
  {{ count.value }}
  {% set count.value = count.value + 1 %}
{% endfor %}
