title: Drawing the turtle module
body: <pre><code>from turtle import *
  color('red', 'yellow')
  begin_fill()
  while True:
      forward(200)
      left(170)
      if abs(pos()) &lt; 1:
          break
  end_fill()
  done()
  </code></pre>
  
  <p>I do not understand this part of the code. <code>if abs(pos()) &lt; 1:</code> what does it mean?</p>
