We use a similar technique as Erkan, but we don't rely on putting all of our paths in PYTHONPATH any longer. Instead, the only path in PYTHONPATH is the location of a sitecustomize.py file. sitecustomize.py is a magic file that python will import automatically at initialization time. One trick with it is you can only ever have one. When python scans it's initial lib paths, if it finds a file named sitecustomize.py it will import and execute it.
The issue that cropped up from using PYTHONPATH is it will insert all paths found in it to the beginning of the sys.path. If it's only a single path, then using PYTHONPATH should be fine. If you're going to have multiple network locations in it, you may want to look at alternatives due to paths found in PYTHONPATH being inserted before the standard python lib paths. Because the network locations were at the beginning, python would stat the network files system for the standard python modules like os, sys, etc causing unnecessary slowdowns. Instead what we did is we created a second environment variable, PSYOP_PYTHONPATH, and have logic in our sitecustomize.py file to take the paths present in PSYOP_PYTHONPATH and append them to the sys.path at python startup. That's the simple version of what we are doing with sitecustomize.py, we also have a bunch of additional code for dealing with project context, per show code, etc. Of course what Erkan said is correct, I just wanted to point out an alternative if you notice some slowdowns once you've implement it.
