How to output a comma delimited list in jinja python template?

Question

If I have a list of users say [\"Sam\", \"Bob\", \"Joe\"], I want to do something where I can output in my jinja template file:

{%          


        

Answer 1

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last }}
