I want to get an image that is used for the background of a sprite but I don’t know how.

import pygame
pygame.init()

screen = pygame.display.set_mode(500, 500)

class Sprite(pygame.sprite.Sprite):
    def __init__(self):
        super(Sprite, self).__init__()
        self.surf = pygame.Surface((50, 50))
        self.surf = pygame.image.load("image.png").convert()

sprite = Sprite()

print(sprite.something) # ideally something that will return "image.png"

All I require is something that will return the background image of the sprite

I searched on the internet for a while and either nobody has asked this, the answer is blatantly obvious or I worded my search incorrectly. I have only tried image.surf.image (a guess) which created an error.
