jinja2: TemplateSyntaxError: expected token ',', got 'string'

I am new to Jinja2 and having an issue with using python regular expression (re). In the following code I would like to bold the lines that have error string in them.

{% block content %}
<div class="container">
{% for l in lines %}
{% if"Error", l) %} {# <<< Throws error #}
<b> {{ l }} </b>
{% else %}
{{ l }} <hr>
{% endif %}
{% endfor %}
{% endblock %}

The above throws following error:

TemplateSyntaxError: expected token ',', got 'string'

Answer Source

Raw python code is not fully supported in jinja2 template syntax.

{% if"Error", l) %}

replace this line with

{% if "Error" in l %}

can fix your problem.

if your logical condition is more complicated, you should consider defining your own custom filters(which can call any python code) or do the complicated things in your view layer. also go check global namespace.
