How to create a button click condition?

Question

Django

There is a paginator like this:

<ul class ='paginate'>
            <li>
                <a href="#">Previous</a>
            </li>
            
            {% for n in page_obj.paginator.page_range %}
            {% if n > page_obj.number|add:-3 and n < page_obj.number|add:3 %}
            <li><a href="?page={{ n }}">{{ n }}</a></li>
            {% endif %}
            {% endfor %}
            <li><a href="#">Next</a></li>
        </ul>

You need to implement the Previous and Next buttons. I see two ways to do this: create a condition if the button is pressed - add or subtract to the variable n and follow the link. Or write something like n+1 or n-1 already in the link. I do not understand how to implement all this, it gives an error on my attempts. Please tell me both ways.

(Wearily) read the docs https://docs.djangoproject.com/en/3.0/ref/paginato... and don't come up with some crazy stuff.
