title: python imports from file to the system
body: <p>If I have a python file contains lines as below :</p>
  
  <pre><code>### my_library.py
  #---------
  import Test1 as test 
  import Test2 as tst
  import project1 as prj
  #---------
  </code></pre>
  
  <p>and I want to make these modules defined in all my other files in the same directory. I want to make these imports as general imports for the system's python.
  If I add the file path in PYTHONPATH enviroment varaible nothing will happen.
  Any suggestions please ?</p>
