title: Python Recursive Turtle Tree with Random Length
body: <p>I am having trouble incorporating the random function into my Recursive Tree function.</p>
  
  <p>The Random should take the length given in drawTree and add/subtract a range of 0 - length//2.</p>
  
  <p>I have the random line at the beginning of the function but it does not change my graphic at all.</p>
  
  <pre><code>def drawTree(length, generations):
      length = random.randint(-length//2,length//2)
      if generations == 0:
          pass
      else: 
          turtle.forward(length)
          turtle.left(45)
          drawTree(length/2, generations -1)
          turtle.right(90)
          drawTree(length/2, generations -1)
          turtle.left(45)
          turtle.backward(length)
  </code></pre>
  
  <p>My <code>drawScene()</code> function works properly</p>
  
  <p>Is the random line not in the right place?</p>
