title: Calculating a range of an exact number of values in Python
body: <p>I'm building a range between two numbers (floats) and I'd like this range to be of an exact fixed length (no more, no less).  <code>range</code> and <code>arange</code> work with steps, instead. To put things into pseudo Python, this is what I'd like to achieve:</p>
  
  <pre><code>start_value = -7.5
  end_value = 0.1
  my_range = my_range_function(star_value, end_value, length=6)
  
  print my_range
  [-7.50,-5.98,-4.46,-2.94,-1.42,0.10]
  </code></pre>
  
  <p>This is essentially equivalent to the R function <code>seq</code> which can specify a sequence of a given length. Is this possible in Python?</p>
  
  <p>Thanks.</p>
