Aand... i've solved it with help of idnar from #twisted: set PYTHONPATH="C:\Documents and Settings\Konrads\My Documents\nfscraper\src" on Windows is not the same as PYTHONPATH=C:\Documents and Settings\Konrads\My Documents\nfscraper\src. Note the doube quotes. Double quotes make sys.path look like this: C:\Documents and Settings\Konrads>C:\Python26\python.exe Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.
import sys filter(lambda x: x.find("foo")>-1,sys.path) ['C:\\Documents and Settings\\Konrads\\"C:\\foo"']
