What is a QuerySet in Django?
Before combining QuerySets, let’s have a quick refresher on what a QuerySet is in Django. A QuerySet is a collection of database queries to retrieve data from your database. It represents a set of records from a database table or a result of a database query. Query sets are lazy, meaning they are not evaluated until you explicitly request the data, which makes them highly efficient.
