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

In a Jinja2 template, you can output a comma-delimited list by using the join filter to concatenate the elements of a list or sequence with commas between them. Here's how you can do it:

<ul> {% for item in items %} <li>{{ item }}</li> {% endfor %} </ul> <p>Comma-Delimited List: {{ items | join(', ') }}</p>

In this example:

  1. We assume that you have a list called items that you are iterating over in a previous part of your template (e.g., in an unordered list).

  2. After the loop, we use {{ items | join(', ') }} to output a comma-delimited list of the elements in the items list. The join filter concatenates the elements of the list with commas and a space (', ') between them.

When you render this template with your data and a list of items, it will generate an HTML list with the items and a paragraph containing the comma-delimited list of the same items.
