Why is QuerySet not iterable?

Question

Django

{{topSale}}//(<QuerySet [<Product: Киви>, <Product: Морковь>, <Product: Гранат>]>,)
            {% for i in topSale %}
                 {{i}}//<QuerySet [<Product: Киви>, <Product: Морковь>, <Product: Гранат>]>

In square brackets, a list that is already normally iterable.
view

topSale = Product.objects.order_by('-is_view')[0:3],

Answer 1

The comma creates a tuple
