A module __init__.py from a folder cannot import the modules in that folder
<p>Using python 3. I am trying to experiment with a wxpython module "aui"</p>

<p>I copied aui folder from wxPython-src-3.0.2.0\wxPython\wx\lib\agw\aui into my project directory</p>

<p>For example:</p>

<pre><code>/aui (Folder)

    __init__.py 
    aui_constants.py
    aui_switcherdialog.py
    ...
    ...
    tabmdi.py

myfile.py
</code></pre>

<p>In myfile.py, I tried simply</p>

<pre><code>import aui 
</code></pre>

<p>__init__.py which in turn tries:</p>

<pre><code>from aui_constants import *
from aui_utilities import *
from auibar import *    
</code></pre>

<p>...but raises import error from even they are in the same folder as __init__.py</p>

<pre><code>from aui_constants import *
ImportError: No module named 'aui_constants'
</code></pre>
