title: Key Control of a Rectangular Figure in Python (Breakout Recreation)
body: <p>When I run this program, I can only move the paddle to the left. I need to be able to move it both directions (on the x plane, aka right and left) while not having to rewrite the whole program. Sorry if the answer is simple and I just missed something.</p>
