Now that Myrtle is on the screen, letโs start adding the ability for the user to interact with her!
Add the following to MoveObject.py:
# MoveObject.py
    def turn_left(self):
        ##
        self.left(90)
        ##
        pass
Then add the following to Characters.py:
# Characters.py
class UserTurtle(CustomTurtle):
    def __init__(self, colour, shape, speed, game, start_position):
        super().__init__(colour, shape, speed, game, True, start_position)
        ##
        turtle.onkey(self.turn_left, 'Left')
        ##
Now when you press the left arrow key, Myrtle will rotate to the left!
Run the code and press the left arrow key, watch Myrtle spin!
