Hi - first time with Jinja, and not very clever I am sure.

I need to pass something like "1,2,3" to the jquery sparkline plugin.

I have a list = [1,2,3].

First I tried list comprehension:

 {{ ', '.join([str(x) for x in list]) }}


But jinja does not support this. Then I tried enumerate:

{% for p, i in enumerate(list) %}
{% if p == 0 %}
{{ i }}
{% else %}
,{{ i }}
{% endif %}
{% endfor %}


 But jinja does not like enumerate either? There must be a smart way of 
doing this?

Thanks in advance.
