Pygame wall collision

Question

class Wall(pygame.sprite.Sprite):
    def __init__(self, x, y, width, height):
        super().__init__()
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.image = pygame.Surface((width, height))
        self.image.fill(BLACK)  # Black color represents the wall
        self.rect = self.image.get_rect()
        self.mask = pygame.mask.from_surface(self.image)
        self.rect.x = self.x
        self.rect.y = self.y


    def draw(self):
        screen.blit(self.image, (self.x, self.y))

    def check_collision(self):
        offset_x = self.x - player.x
        offset_y = self.y - player.y
        return player.mask.overlap(self.mask, (offset_x, offset_y))

This is my wall class

and

    for wall in walls:
        wall.draw()
        if wall.check_collision():
            if player.x > wall.x:  # 오른쪽 벽에 닿았을 때
                player.x += wall.width
            else:  # 왼쪽 벽에 닿았을 때
                player.x = wall.x - player.rect.width
            if player.y > wall.y:  # 아래쪽 벽에 닿았을 때
                player.y = wall.y + wall.height
            else:  # 위쪽 벽에 닿았을 때
                player.y = wall.y - player.rect.height

This is my game loop about walls. But when I collide with walls with my sprite The sprite when opposite of the wall.

I hope the walls would work very normal. Please help.
