title: chunk_split in python
body: <p>I'm trying to find a pythonic way to do this PHP code:</p>
  
  <pre><code>chunk_split(base64_encode($picture));
  </code></pre>
  
  <p><a href="http://us2.php.net/chunk_split" rel="nofollow noreferrer">http://us2.php.net/chunk_split</a></p>
  
  <p>chunk_split split the string into smaller chunks of 76 character long by adding a "\r\n" (RFC 2045). </p>
  
  <p>thank you</p>
