How to display a dictionary element in a template?

Question

Django

Good night everyone.
The essence of the question is this:
I pass the items object to the template. Elements have id, title, link fields.
Also, I pass a counts dictionary with the following content {8: 136, 1: 6, 18: 2, 19: 1, 17: 1}
Counts a dictionary of element counters by category
Items - categories
I need to display in the template Category and the number of items in it The
question is how do I request the element counts from item.id ??
Tried: counts.item.id, counts[item.id], {{counts.{{item.id}}}} - all result is the same - server returns 502
error
, if I do {{counts.8}}

{% if items %}
    {% for item in items %}
        <p><a href="/video/{{ item.link }}">{{ item.title }}</a> — {{ counts }}</p>
    {% endfor %}
{% endif %}
