Post.objects.all() returns a QuerySet. It is a lazy data structure representing a set of Post model objects from the database. It does not fetch data immediately but does so only when necessary (for example, when iterating over the QuerySet). The value type is django.db.models.query.QuerySet.

// Example usage
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

    def __str__(self):
        return self.title

# Getting all posts as a QuerySet
all_posts_queryset = Post.objects.all()

// Type of the returned value
# print(type(all_posts_queryset)) # Will output <class 'django.db.models.query.QuerySet'>

// Iterating over the QuerySet fetches data from the database
# for post in all_posts_queryset:
#     print(post.title)
