Why does ' from fileName import * 'not work

so I have two files: main.py and settings.py

I am trying to import everything from settings.py into main.py using from settings import *

It just returns this error:

Traceback (most recent call last):  File "d:\Programming\3DGAME\main.py", line 37, in <module>    game = Game()           ^^^^^^  File "d:\Programming\3DGAME\main.py", line 10, in __init__    self.screen = pg.display.set_mode(RES)                                      ^^^NameError: name 'RES' is not defined

this is main.py:

import pygame as pgimport sysfrom settings import *class Game:     def __init__(self):        pg.init()        self.screen = pg.display.set_mode(RES)        self.clock = pg.time.Clock()    def new_game(self):        pass    def update(self):        pg.display.flip()        self.clock.tick(fps)        pg.display.set_caption(f'{self.clock.get_fps() :.1f}')    def draw(self):        self.screen.fill('black')    def check_events(self):        for event in pg.event.get():            if event.type == pg.QUIT or (event.type == pg.KEYDOWN and event.key == pg.K_ESCAPE):                pg.quit()                sys.quit()    def run(self):        while True:            self.check_events()            self.update()            self.draw()if __name__ == '__main__':    game = Game()    game.run()

this is settings.py:

RES = WIDTH, HEIGHT = 1600, 900fps = 60

It only works if I transfer the vars into main.py. I also tried to ask for specific vars like: from settings import RES. still no work smh
