title: How to use modern string formatting options with Python's logging module?
body: <p>The <a href="http://docs.python.org/2/howto/logging.html#logging-variable-data" rel="noreferrer">Python logging tutorial</a> says that the newer ways of formatting are beyond the scope of the tutorial, without mentioning where to learn about it.</p>
  
  <p>I would appreciate any examples or link to documentation that allow me to use <code>.format()</code> style message formatting in logging calls such as <code>debug()</code>, <code>info()</code>, etc.</p>
