I’m using the Jinja2 as a template engine to generate a static HTML site in a Python script.

I want to repeat the contents of a block (title) in the layout template (html layout.), that is like:

<html>
<head>
    <title>{% block title %}{% endblock %} - {{ sitename }}</title>
</head>
<body>
    <h1>{% block title %}{% endblock %}</h1>
    <div id="content">
        {% block content %}{% endblock %}
    </div>
</body>
</html>

This template will be extended by another similar template:

{% extends "layout.html" %}
{% block title %}Titulo da pagina{% endblock %}
{% block content %}
Aqui vai o conteudo da pagina
{% endblock %}

But this does not work, resulting in an error:

jinja2.exceptions.TemplateAssertionError: block 'title' defined twice

jinja2 plays the second {% block title %} in the html layout. as a block reset.

How can I repeat the contents of a block in the same template, with jinja2?

python jinja2
