I found a nice image of space that I'd like sitting in the background of this tiny game I'm working on and can't figure out what and where to write it. It needs to be placed behind all classes to make sure that it doesn't block the screen. I thought it might be in class Window, but I'm not sure. I am brand new to python so any help is much appreciated! This is the entire project so far.

Yes, you should be able to add it to class window...
You could do something like this to add it:
def __init__(self, width, height, title):
super().__init__(width, height, title)
file_path = os.path.dirname(os.path.abspath(__file__))
os.chdir(file_path)
self.set_mouse_visible(True)
arcade.set_background_color(open_color.black)
self.bullet_list = arcade.SpriteList()
self.enemy_list = arcade.SpriteList()
self.enemy_bullet_list = arcade.SpriteList()
self.player = Player()
self.score = 0
self.win = False
self.lose = False
self.background = None
def setup(self):
'''
Set up enemies
'''
self.background = arcade.load_texture("images/background.jpg")
for i in range(NUM_ENEMIES):
x = 120 * (i+1) + 40
y = 500
enemy = Enemy((x,y))
self.enemy_list.append(enemy)
