title: Relative import with Python 3 from folder containing a dot
body: <p>Say I have the following structure:</p>
  
  <pre><code>main.py
  .folder/
      a.py
      b.py
  </code></pre>
  
  <p>and using Python 3 and being currently in <code>main.py</code> I want to <code>import *</code> from <code>a.py</code>.</p>
  
  <ul>
  <li>I assume <code>from .folder.a import *</code> is wrong as that ignores that the folder is actually named <code>.folder</code>, not <code>folder</code></li>
  <li>I assume <code>from ..folder.a import *</code> is wrong as I'm not targeting a relative parent directory called <code>folder</code>, but a folder named <code>.folder</code> within the same directory as <code>main.py</code></li>
  </ul>
