For templating, that is why I prefer Jinja2 with macros instead of Django templates.

  {% macro IssueCard(issue, type) -%}
     ... lot of HTML
  {% endmacro -%}
  {% for issue in myissues %}
    {% macro IssueCard(issue, 'myissue') %}
  {% endfor %}

The alternative is creating template tags, which can be a lot of work, and it gets you out of the templates.

I have a folder called macros/ where I put all the macros I need, and then I use the import call from Jinja2.

I agree with you; having long and deeply nested HTML templates creates too much noise when developing. Jinja2 Macros help with that.
