So where does sys.path get its value from, and how do I change it? You can use my PEP 370 (http://python.org/dev/peps/pep-0370/) and a .pth file to extend the search path for modules. import os import site site.USER_SITE '/home/heimes/.local/lib/python2.6/site-packages' if not os.path.isdir(site.USER_SITE): ... os.makedirs(site.USER_SITE) ... pth = open(os.path.join(site.USER_SITE, michal.pth), w) pth.write(C:/Users/Michael/Code/Python\n) pth.close() Restart Python, your custom search path should be in sys.path.

So in your 'main' module where you do most of your imports, just append or prepend the path you desire (the search order is left to right). Although, I believe under Windows creating a system level or user level PYTHONPATH environment variable will enable Windows to pick it up. Not 100% sure as I don't have a Windows machine handy. -- http://mail.python.org/mailman/listinfo/python-list

So where does sys.path get its value from, and how do I change it? sys.path gets its values from several places. The ones I think I know of are: current directory (which uses rather than the expected .) directories listed in PythonPath environment variable Windows-system directory relative to the executable (python.exe or pythonw.exe) that's actually running relative to the user directory (docssettings/username/Application Data If there's no PythonPath variable, it just uses those other items.

The simplest hack (worst - but most direct) is that sys.path is a list and you can use it like any other list. (add, delete, change items in it) It gets loaded from site.py (in the standardard library) at startup. Anything else you'll have to ask somebody else.
