STEP 7: We can see our player on the stage now, but we need to return the sprite from add_player() in order to use the sprite in our main() function.
The return statement passes a variable from a function back to where the function is called.
Click on LOGIC. Go to and drag Return Statement to the last line of add_player().
Change the variable being returned from my_var to player. Make sure this return statement is indented!
