title: How to import python file from git submodule
body: <p>I've a project which uses git submodules. In my python file I want to use functions from another python file in the submodule project.</p>
  
  <p>In order to work I had to add the <strong>init</strong>.py file to all subfolders in the path. My folder tree is the following:</p>
  
  <pre><code>myproj
  ├── gitmodules
  │   ├── __init__.py
  │   ├── __init__.pyc
  │   └── mygitsubmodule
  │       ├── __init__.py
  │       ├── __init__.pyc
  │       └── file.py
  └── myfile.py
  </code></pre>
  
  <p>Is there any way to make it work without touching mygitsubmodule ? </p>
  
  <p>Thanks</p>
