How to refer to a model field?

Question

Python

I have two tables:

CREATE TABLE "Users"(
    "id"   Integer PRIMARY KEY,
    "name" Text,
CONSTRAINT "unique_id" UNIQUE ( "id" ) )

CREATE TABLE "addresses"(
    "id"      Integer PRIMARY KEY,
    "email"   Text,
    "user_id" Integer,
    CONSTRAINT "lnk_Users_addresses" FOREIGN KEY ( "user_id" ) REFERENCES "Users"( "id" ), 
CONSTRAINT "unique_id" UNIQUE ( "id" ) )

Here is the code that handles all this:

engine = create_engine('sqlite:///sql_test.db', echo=True)
Session = sessionmaker(bind=engine)
sess = Session()
Base = automap_base()
Base.prepare(engine, reflect=True)
User = Base.classes.Users
addresses = Base.classes.addresses

answer = sess.query(User).filter(User.id==1).first()
print(type(answer)) # class User

If I were writing in a declarative style, then there is a `backref='uuu'` ( link ) feature that I can use to access data from the addresses table. And then how to be?
