When querying in django say People.objects.all(pk=code), what does pk=code mean?
It’s a query to get the People object that has a primary key of whatever the value of “code” is.
By default, all Django model instances have a primary key that uniquely identifies the object. Generally it’s an auto-incrementing integer, but you could define it to be whatever you want, so long as it’s certain to be unique.

Edit: Now that I look at the code snippet a little closer, rather than just assuming what it said, it doesn’t make much sense. The all() method should be a get(). It doesn’t make any sense to give a pk to all() since it just returns all the objects of that type.
