How to use Jinja2 to render templates

To use jinja first import the Template instance from jinja module. The Template instance provides the render method that renders the text-based variables with the jinja pre-defined syntax.

from jinja2 import Template
msg = Template('Hello, {{ name }}!')
out = msg.render(name='Mehrab Mohul')



Hello, Mehrab Mohul!

Render Template with HTML files

<!DOCTYPE html>
    <meta charset="UTF-8">
    <title>{% block title %}{% endblock %}</title>
    {% block content%}
    {% endblock %}
