Answer 1

You can use macro tag and your template will look like this

{% macro create_block(title, message) %}
    <h1>{{title}}</h1>
    <p class="important">
      {{message}}
    </p>
{% endmacro %}

{% for title, message in list %}
    {{ create_block(title, message) }}
{% endfor %}

I test it and it's my script:

from jinja2 import Template

titles = ['1 title', '2 title']
messages = ['1 message', '2 message']


template = Template("""
{% macro create_block(title, message) %}
<h1>{{title}}</h1>
    <p class="important">
      {{message}}
    </p>
{% endmacro %}

{% for title, message in list %}
{{ create_block(title, message) }}
{% endfor %}
""")

print template.render(list=zip(titles, messages))

And it's my output

    <h1>1 title</h1>
    <p class="important">
      1 message
    </p>

    <h1>2 title</h1>
    <p class="important">
      2 message
    </p>

I hope it solved you problem
