Comment:

 Hey Can! You want to add a note something like, ''If the queryset has
 already been fully retrieved, count will use that length rather than
 perform an additional query'' to the
 
[https://docs.djangoproject.com/en/3.2/ref/models/querysets#django.db.models.query.QuerySet.count
 count() reference]? Sounds OK, yes.

 there is no document for count function docstring.

 """
 ...

 If the QuerySet is already fully cached, return the length of the
 cached results set to avoid multiple SELECT COUNT(*) calls.
