Django's Object-Relational Mapping (ORM) system is one of its most powerful features, allowing developers to interact with databases using Python code instead of writing raw SQL queries.
One of the advanced features of Django's ORM is the ability to annotate querysets.
The annotate() function is a versatile tool that can be used to perform aggregations, add computed fields, and more to your query results.
In this article, we'll dive into how to use annotate() effectively in your Django projects.

The result is that each item in the queryset will have an additional attribute, which is the result of the annotation.
