title: Jinja2 Split string by white spaces
body: <p>I'm using Jinja2 template engine (+pelican). </p>
  
  <p>I have a string saying "a 1", and I am looking for a way to split that string in two 
  by using the white-space as the delimiter.</p>
  
  <p>So the end result I'm looking for is a variable which holds the two values in a form of an array. e.g. str[0] evaluates to "a" &amp; str[1] evaluates to "1". </p>
  
  <p>Thanks in advance.  </p>
