Here is the code:

        random.shuffle(starts)
        self.x = starts[0]
        self.y = -3
        self.canvas_height = self.canvas.winfo_height()

Please use python and output tags when posting code and results. The icode tags are for inline code.

Class Paddle is indented under class Ball. Currently it can only be accessed by Ball.Paddle(). You probably just want to unindent that section of code.

Thank you so much! Sorry about how I posted it. I'm still learning. I'll make sure to do it right next time.
