I don't get what Poll.objects.get(pk=1) does

Hi,

I'm learning Django (I already know Python) and I'm following the
tutorial: https://docs.djangoproject.com/en/1.3/intro/tutorial01/
At the end of the tutorial there is a code where the programmer does:
p = Poll.objects.get(pk=1) .
I want to be sure if I understand it well.
Poll.object.get(pk=1) is returning the poll which primary key is 1 in
the DB, isn't it?
This is stored in p, which is actually the poll which pk is 1, so it's
itselft but with new class variables added (the other side of the
Foreign Keys). Is it correct?
This creates a new class variable called choice_set because Choise is
an other-side foreign key of poll.
This object (choise_set, of type RelatedManager) has a method create
that adds things to the set.

Did I understand it well??

Thank you,

(PS: sorry for my english )
