title: How to move turtle to edges of the canvas?
body: <p>Is there any way to make the cursor (the turtle) go to the right , left, down and upper edge of the canvas?</p>
  
  <p><a href="https://stackoverflow.com/a/10315510/939986">Someone suggested</a> to use <code>turtle.setx()</code> with argument as <code>0</code> to move to leftmost position. But when I do so, the turtle is moved to the default position <em>(to the center)</em>.</p>
