Using select to sum and join at the same time

So I got two tables

db.execute("""CREATE TABLE persons (
               id INTEGER PRIMARY KEY AUTOINCREMENT,
               firstname TEXT NOT NULL,
               surname TEXT NOT NULL,
               UNIQUE (firstname, surname) ON CONFLICT IGNORE
              )""")

and

db.execute("""CREATE TABLE scores (
               task INTEGER,
               idPerson INTEGER,
               score INTEGER NOT NULL
            )""")

using this select function I can get the following result:

cursor = db.execute("SELECT firstname, surname, uppgift, score FROM persons JOIN scores ON id = idPerson")

    ('Nils', 'Johansson', 1, 1)
    ('Maria', 'Johansson', 1, 2)
    ('Anna', 'Andersson', 1, 0)
    ('Karl', 'Eriksson', 1, 2)
    ('Nils', 'Eriksson', 1, 1)
    ('Anders', 'Eriksson', 1, 0)
    .
    .
    .
    ('Sven', 'Persson', 100, 0)
    ('Anders', 'Persson', 100, 2)
    ('Maria', 'Persson', 100, 1)
    ('Kristina', 'Persson', 100, 2)

with firstname, surname, task, score.

and with the following function results gets me the sum of the score:

db.execute("SELECT idPerson, SUM(score) FROM scores GROUP BY idPerson ORDER BY idPerson DESC")



(5, 29)
(4, 33)
(3, 19)
(2, 37)
(1, 33)

with id and total score.

what I need to do is in the first result not get the score for each individual task but rather the total score like in the last result. Is this possible?
