title: Add whitespace to string every 3 characters in Jinja2
body: <p>I have a source of youtube viewcounts, and I want to represent them separated every 3 characters.</p>
  
  <p>Examples:
  My source is 1897584, I want it to be: 1 897 584;
  1200, I want it to be: 1 200...
  234989, 234 989...
  123, 123...
  and so on...</p>
  
  <p>Is it possible to split the string every 3 characters using only jinja2?</p>
  
  <p>Cheers in advance.</p>
