import function from a file in the same folder : <p>I'm building a Flask app with Python 3.5 following a tutorial, based on different import rules. By looking for similar questions, I managed to solve an ImportError based on importing from a nested folder by adding the folder to the path, but I keep failing at importing a function from a script in the same folder (already in the path). The folder structure is this:</p>

<pre><code>DoubleDibz  
├── app
│   ├── __init__.py
│   ├── api 
│   │   ├── __init__.py
│   │   └── helloworld.py
│   ├── app.py
│   ├── common
│   │   ├── __init__.py
│   │   └── constants.py
│   ├── config.py
│   ├── extensions.py
│   ├── static
│   └── templates
└── run.py
</code></pre>

<p>In app.py I import a function from config.py by using this code:</p>

<pre><code>import config as Config
</code></pre>

<p>but I get this error: </p>

<pre><code>ImportError: No module named 'config'
</code></pre>

<p>I don't understand what's the problem, being the two files in the same folder.
Thanks in advance </p>
