title: Generate/create a random list of positive and negative floating numbers
body: <p>I would like to create a random list of positive and negative floating numbers within a range
  Like this:</p>
  
  <p>0.1, 1.5, 0.6, -1.3, -0.4 and so on.</p>
  
  <p>I know we have something of the likes of: </p>
  
  <pre><code>import random    
  my_randoms = random.sample(xrange(100), 10)
  </code></pre>
  
  <p>But this seems to get me the floating and negative part of the list.</p>
  
  <p>Thank very much, any help is much appreciated. </p>
