title: How to make Jupyter notebook use PYTHONPATH in system variables without hacking sys.path directly?
body: <p>Same problem as in this question <a href="https://stackoverflow.com/q/34976803/1568919">sys.path different in Jupyter and Python - how to import own modules in Jupyter?</a>. In pure Python, it prepends my system environment variable PYTHONPATH to sys.path but Jupyter notebook doesn't, so I can't import my own module.</p>
  
  <p>There are many similar questions asked on SO, and the solution is to directly manipulate sys.path in the script. </p>
  
  <p>Is there a way to make Jupyter notebook use my system PYTHONPATH variable, as in pure python?</p>
