title: How to setup python.logging format using f-string style
body: <p>I'm writing an app using python 3.7 and want to use only <strong>f-strings</strong> in it.</p>
  
  <p>I'm using python logging module in order to log my application correctly, and I want to use a specific format but the documentation (and the web) only example how to change the format using %-strings.
  I was wondering whether there is an option to set the logger format using f-strings</p>
  
  <pre class="lang-py prettyprint-override"><code>LOG_FORAMT = ('%(levelname)s -10s %(asctime)s -10s %(message)s') # Known example
  
  f-LOG_FORMAT = (f'{logger.levelname} -10s') # Something like that?
  </code></pre>
