Demystifying Jinja Control Structures for Beginners 🚀

Jinja templating brings the magic of control structures to your Python web applications! Let’s unravel the enchanting world of FOR loops and IF-ELIF-ELSE statements.

FOR LOOP: Unleashing Iterative Magic ✨

Loop through a sequence effortlessly with a FOR loop. Picture a list of users stored in a variable called users:

<ul>
  {% for user in users %}
    <li>{{ user.username }}</li>
  {% endfor %}
</ul>

Here, we’re conjuring an unordered list, revealing the usernames from our users variable, one enchanting loop at a time.

IF-ELIF-ELSE: Casting Conditional Spells 🧙‍♂️

Jinja’s IF-ELIF-ELSE structure mirrors the logic found in other programming languages. Witness its power:

{% if users %}
  <ul>
    {% for user in users %}
      <li>{{ user.username|e }}</li>
    {% endfor %}
  </ul>
{% endif %}

Behold! If the mystical users are present, an enchanted list will materialize, showcasing their usernames with an extra layer of protection.
