I need to use break for a for loop in jinja2. Below is my code: 

{% for i in range (0, desc) %}{{ desclist[i] }} {% set length = length + desclist[i]|length %}{% if length >= 70 %}{% break %}{% endif %}{% endfor %}

and to import the loopcontrol extension:

enter image description here

However, I got an error as followed:

jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'break'.
Jinja was looking for the following tags: 'elif' or 'else' or 'endif'. The
innermost block that needs to be closed is 'if'.

Any idea to make this work? Thank you.

Encountered the same issue, and realized on top of the document

it says:

The following example creates a Jinja environment with the i18n extension loaded: jinja_env = Environment(extensions=['jinja2.ext.i18n'])

So I tried this and it finally resolved the error of ... Encountered unknown tag ...:

jinja_env = Environment(extensions=['jinja2.ext.loopcontrols'])
