title: python - splitting a string without removing delimiters
body: <p>I'm trying to split a string without removing the delimiter and having trouble doing so.  The string I want to split is: </p>
  
  <pre><code>'+ {- 9 4} {+ 3 2}'
  </code></pre>
  
  <p>and I want to end up with </p>
  
  <pre><code>['+', '{- 9 4}', '{+ 3 2}']
  </code></pre>
  
  <p>yet everything I've tried hasn't worked.  I was looking through this stackoverflow post for answers as well as google:  <a href="https://stackoverflow.com/questions/7866128/python-split-without-removing-the-delimiter">Python split() without removing the delimiter</a></p>
  
  <p>Thanks!</p>
