title: What is %% for in Python?
body: <p>I'm trying to understand the following Python quine:</p>
  
  <pre><code>s = 's = %r\nprint(s%%s)'
  print(s%s)
  </code></pre>
  
  <p>In particular, I'm having trouble finding any info about that %% part.
  Anyone know what that does exactly, in this context?</p>
  
  <p>Postscript: Sorry for the silly question - it's just an escape character.
  My google search was focused on %%, which didn't lead me in the right direction. Thanks to those who took the time to respond!   :)</p>
