title: Split string on white space
body: <p>I have this weird formatted text file I am trying to read in and I don't know how to tell python that each line begins with a delimiter.</p>
  
  <p>A row in the text file look like:</p>
  
  <pre><code>     3.146    -1.339      .358    29.214
  </code></pre>
  
  <p>The file uses 5 spaces as the delimiter.  How can I read each line into a list with 4 items?</p>
