title: python code output not showing on windows 10 terminal
body: <p>I typed this code to make a ping pong game. But when I run the code, the terminal does not show the two paddles I made.</p>
  <pre><code>import turtle
  
  wn = turtle.Screen() 
  wn.title(&quot;Pong By Samuel Hwang&quot;)
  wn._bgcolor(&quot;black&quot;)
  wn.setup(width=800, height=600)
  wn.tracer(0)
  
  while True:
      wn.update()
  
  paddle_a = turtle.Turtle()
  paddle_a.speed(0)
  paddle_a.shape(&quot;square&quot;)
  paddle_a.color(&quot;white&quot;)
  paddle_a.shapesize(stretch_wid=5, stretch_len=1)
  paddle_a.penup()
  paddle_a.goto(-350, 0)
  paddle_b = turtle.Turtle()
  paddle_b = turtle.Turtle()
  paddle_b.speed(0)
  paddle_b.shape(&quot;square&quot;)
  paddle_b.color(&quot;white&quot;)
  paddle_b.shapesize(stretch_wid=5, stretch_len=1)
  paddle_b.penup()
  paddle_b.goto(350, 0)
  </code></pre>
  <p>What did I do wrong there?</p>
