title: Python fileConfig issue
body: <p>I was following <a href="http://michal.karzynski.pl/blog/2016/06/19/building-beautiful-restful-apis-using-flask-swagger-ui-flask-restplus/" rel="nofollow noreferrer">this tutorial</a> to run <a href="https://github.com/postrational/rest_api_demo" rel="nofollow noreferrer">app.py</a> they provided.</p>
  
  <p>With the first try of running app.py I had an error </p>
  
  <pre><code>Traceback (most recent call last):
    File "E:/GIT_repos/SBD/rest_api_demo/rest_api_demo/app.py", line 11, in &lt;module&gt;
      logging.config.fileConfig('logging.conf')
    File "C:\Users\hunte\AppData\Local\Programs\Python\Python35\lib\logging\config.py", line 76, in fileConfig
      formatters = _create_formatters(cp)
    File "C:\Users\hunte\AppData\Local\Programs\Python\Python35\lib\logging\config.py", line 109, in _create_formatters
      flist = cp["formatters"]["keys"]
    File "C:\Users\hunte\AppData\Local\Programs\Python\Python35\lib\configparser.py", line 956, in __getitem__
      raise KeyError(key)
  KeyError: 'formatters'
  </code></pre>
  
  <p>Errors vanished after I have replaced
  line 11 in app.py:</p>
  
  <pre><code>logging.config.fileConfig('logging.conf')
  </code></pre>
  
  <p>to</p>
  
  <pre><code>logging.config.fileConfig('../logging.conf')
  </code></pre>
  
  <p><strong>Question</strong>
  Was code of the tutorial faulty or is it something I did <strong>&amp;</strong> What may be the cause, that other people doing this tutorial (I assume, looking at the comments) didn't have to change anything, while I had to?</p>
