Hi, I am learning / teaching python using Makecode Arcade. I’m trying to understand what the generated code means by “Ballie: Sprite = None”.

What does Sprite = None even mean?

Code in Python:

```auto
@namespace
class SpriteKind:
    Ball = SpriteKind.create()

def Make_Ball_Sprite():
    global Ballie
    Ballie = sprites.create(img("""
            . . . . . b b b b b b . . . . . 
                    . . . b b 9 9 9 9 9 9 b b . . . 
                    . . b b 9 9 9 9 9 9 9 9 b b . . 
                    . b b 9 d 9 9 9 9 9 9 9 9 b b . 
                    . b 9 d 9 9 9 9 9 1 1 1 9 9 b . 
                    b 9 d d 9 9 9 9 9 1 1 1 9 9 9 b 
                    b 9 d 9 9 9 9 9 9 1 1 1 9 9 9 b 
                    b 9 3 9 9 9 9 9 9 9 9 9 1 9 9 b 
                    b 5 3 d 9 9 9 9 9 9 9 9 9 9 9 b 
                    b 5 3 3 9 9 9 9 9 9 9 9 9 d 9 b 
                    b 5 d 3 3 9 9 9 9 9 9 9 d d 9 b 
                    . b 5 3 3 3 d 9 9 9 9 d d 5 b . 
                    . b d 5 3 3 3 3 3 3 3 d 5 b b .

        """),
        SpriteKind.Ball)
    Ballie.set_velocity(100, 100)
    Ballie.set_position(80, 0)
    Ballie.set_stay_in_screen(False)
    Ballie.set_bounce_on_wall(True)

Ballie: Sprite = None
Make_Ball_Sprite()

```

All variables in Blocks are global variables. Your variable, `Ballie`, is created in the “main” portion of your Python program (it’s the equivalent to `on start` in blocks) to make it a global variable. Because you don’t assign it a value in `on start`, it is set to `None` (the Python equivalent to `null` in other programming languages).
