title: How to stop turtle from drawing even with pen up?
body: <p>I am using the turtle module in python. the problem is that whenever I have the turtle move i will draw even if the pen is up. for example if I run this program:</p>
  
  <pre><code>import turtle
  
  turtle.penup
  turtle.goto(0,50)
  </code></pre>
  
  <p>the turtle will still draw a line when it moves  to (0,50)
  why is this and how can it be prevented?</p>
