'Is it possible to edit the page_obj before passing template?

I can catch <class 'django.core.paginator.Page'> in get_context_data function of django view class.

What I want to do is alter the showing item and get it back to <class 'django.core.paginator.Page'> again.

django.core.paginator.Page source code is here. https://docs.djangoproject.com/en/4.0/_modules/django/core/paginator/

I found it has object_list,so I try to change

def get_context_data(self):
    temp = super().get_context_data() 
    print(type(temp['page_obj'])) #<class 'django.core.paginator.Page'>
    new_object_list = []
    for t in temp['page_obj'].object_list:## I can iterate the item here.
        # make new_object_list here

    temp['page_obj'].object_list = new_object_list 
    print(temp) # nothing changes
    return temp

However object_list doesn't change.

python django
