title: Python importing a module from a parallel directory
body: <p>How would I organize my python imports so that I can have a directory like this.</p>
  
  <pre><code>project
  |      \
  |      __init__.py
  |     
  src
  |   \
  |    __init__.py
  |    classes.py
  |
  test
      \
       __init__.py
       tests.py
  </code></pre>
  
  <p>And then inside /project/test/tests.py be able to import classes.py</p>
  
  <p>I've got code looking like this in tests.py</p>
  
  <pre><code>from .. src.classes import(
      scheduler
      db
  )
  </code></pre>
  
  <p>And am getting errors of </p>
  
  <pre><code>SystemError: Parent module '' not loaded, cannot perform relative import
  </code></pre>
  
  <p>Anyone know what to do?</p>
