STEP 6: Let's fill in the add_player() function. Remember to add new function code below the docstring!

Click on GRAPHICS. Go to and place Player 1 within add_player().
Change the name of the sprite to player. Position the player sprite at (0, -155).
Click on LOGIC. Go to . On the last line of main(), drag Function Call into Variable.
Change my_var to player and change the function from my_function() to add_player().
