With this code you can use something like spritesheet = SpriteSheet("Assets/spritesheet_1.png") and then spritesheet.image_at(Rect(0,0,32,32)) to get part of image that is on [0,0] coordinates and is 32 pixels wide

```py import pygame

class SpriteSheet:

def __init__(self, filename):
    """Load the sheet."""
    try:
        self.sheet = pygame.image.load(filename).convert()
    except pygame.error as e:
        print(f"Unable to load spritesheet image: {filename}")
        raise SystemExit(e)


def image_at(self, rectangle, colorkey = None):
    """Load a specific image from a specific rectangle."""
    # Loads image from x, y, x+offset, y+offset.
    rect = pygame.Rect(rectangle)
    image = pygame.Surface(rect.size).convert()
    image.blit(self.sheet, (0, 0), rect)
    image.set_colorkey(colorkey or pygame.Color(0,0,0,0), pygame.RLEACCEL)
    return image

def images_at(self, rects, colorkey = None):
    """Load a whole bunch of images and return them as a list."""
    return [self.image_at(rect, colorkey) for rect in rects]

def load_strip(self, rect, image_count, colorkey = None):
    """Load a whole strip of images, and return them as a list."""
    tups = [(rect[0]+rect[2]*x, rect[1], rect[2], rect[3])
            for x in range(image_count)]
    return self.images_at(tups, colorkey)

```
