Solve the following python programming problem given the following code:
@ _init_events.dispatch_for ('mysql') 
def _init_events(engine, mysql_sql_mode = None, **kw) : 
    'Set up event listeners for MySQL.' 
    if (_check_effective_sql_mode is not None) : 
        @ sqlalchemy.event.listens_for (engine, 'connect') 
        def _set_session_sql_mode(dbapi_con, connection_rec) : 
            cursor = dbapi_con.cursor () 
            cursor.execute ('SET SESSION sql_mode = %s', [mysql_sql_mode]) 
@ sqlalchemy.event.listens_for (engine, 'first_connect') 
    def _check_effective_sql_mode(dbapi_con, connection_rec) : 
        if (mysql_sql_mode is not None) : 
            _set_session_sql_mode (dbapi_con, connection_rec) 
cursor = dbapi_con.cursor () 
        cursor.execute ("SHOW VARIABLES LIKE 'sql_mode'") 
        realmode = cursor.fetchone () 
        if (realmode is None) : 
            LOG.warning (_LW ('Unable to detect effective SQL mode')) 
else : 
            realmode = realmode [1] 
            LOG.debug ('MySQL server mode set to %s', realmode) 
            if (('TRADITIONAL' not in realmode.upper ()) and ('STRICT_ALL_TABLES' not in realmode.upper ())) : 
                LOG.warning (_LW ("MySQL SQL mode is '%s', consider enabling TRADITIONAL or STRICT_ALL_TABLES"), realmode)
