def connect(db):    """ Connect to the database """    try:        # dsn = cx_Oracle.makedsn(host='MYHOST', sid='DEVPRON', port=1521)        conn = cx_Oracle.connect(user = dbconfig._USER, password = dbconfig._PWD, dsn = db)    except cx_Oracle.Error as error:        raise error    else:        cur = conn.cursor()            return conn, cur

def execute(conn, cur, sql, bindvars=None, commit=False):    """    Execute whatever SQL statements are passed to the method;    commit if specified. Do not specify fetchall() in here as    the SQL statement may not be a select.    bindvars is a dictionary of variables you pass to execute.    """    try:        cur.execute(sql, bindvars)     except cx_Oracle.DatabaseError as e:        raise e    if commit:        cur.commit()


conn, cur = db.connect('TITAN')

sql = ("""  select max(id) order_id from orders """)

How do I return result of select into a variable in Python ???

max_order_id = db.execute(conn, cur, sql)
