title: Drawing parallel lines with a turtle
body: <p>I need to write a function that makes parallel lines in turtle and takes the following four parameters:</p>
  
  <ul>
  <li>a turtle</li>
  <li>length, that is the length of each line</li>
  <li>reps, that is the number of lines to draw</li>
  <li>separation, that is the distance between parallel lines</li>
  </ul>
  
  <p>so far I've got this:</p>
  
  <pre><code>import turtle as t
  
  def parallelLines(length, reps, separation):
      t.fd(length)
  
      t.penup()
  
      t.goto(0, separation)
  
      for i in reps:
           return i
  </code></pre>
