# Jinja

Jinja is a fast, expressive, extensible templating engine. Special

placeholders in the template allow writing code similar to Python

syntax. Then the template is passed data to render the final document.

It includes:

-   Template inheritance and inclusion.

-   Define and import macros within templates.

-   HTML templates can use autoescaping to prevent XSS from untrusted

    user input.

-   A sandboxed environment can safely render untrusted templates.

-   AsyncIO support for generating templates and calling async

    functions.

-   I18N support with Babel.

-   Templates are compiled to optimized Python code just-in-time and

    cached, or can be compiled ahead-of-time.

-   Exceptions point to the correct line in templates to make debugging

    easier.

-   Extensible filters, tests, functions, and even syntax.

Jinja's philosophy is that while application logic belongs in Python if

possible, it shouldn't make the template designer's job difficult by

restricting functionality too much.

## In A Nutshell

```jinja

{% extends "base.html" %}

{% block title %}Members{% endblock %}

{% block content %}

  


  {% for user in users %}

    
{{ user.username }}

  {% endfor %}

  

{% endblock %}

```
