Warning: This is the documentation for the development version of Jinja2

Welcome to Jinja2

Jinja2 is a modern and designer-friendly templating language for Python, modelled after Django’s templates. It is fast, widely used and secure with the optional sandboxed template execution environment:

<title>{% block title %}{% endblock %}</title>
<ul>
{% for user in users %}
  <li><a href="{{ user.url }}">{{ user.username }}</a></li>
{% endfor %}
</ul>

Features:

  • sandboxed execution
  • powerful automatic HTML escaping system for XSS prevention
  • template inheritance
  • compiles down to the optimal python code just in time
  • optional ahead-of-time template compilation
  • easy to debug. Line numbers of exceptions directly point to the correct line in the template.
  • configurable syntax
