Example Python syntax for executing insert_user is incorrect

Q&A DQ Courses
#1

In the last chunk of example code, the incorrect syntax for cursor.execute() is used.

import psycopg2
conn = psycopg2.connect("dbname=dq user=dq")
cur = conn.cursor()
cur.execute("""
    PREPARE insert_user(integer, text, text, text) AS
        INSERT INTO users VALUES ($1, $2, $3, $4);
""")
cur.execute("""
    EXECUTE insert_user($s, $s, $s, $s);
""", (10002, '[email protected]', 'Bob', '101 Fake Street'))

The second cur.execute() call should be

cur.execute("""
    EXECUTE insert_user(%s, %s, %s, %s);
""", (10002, '[email protected]', 'Bob', '101 Fake Street'))

where each $s should be %s.
