As others said, use $PYTHONPATH

This is what ipython uses to try and get that information in a portable manner.
Note that it uses _winreg, which is part of the win32 extensions.
In [1]: import IPython.genutils
In [2]: psource IPython.genutils.get_home_dir
def get_home_dir():
"""Return the closest possible equivalent to a 'home' directory.
For Posix systems, this is $HOME, and on NT it's $HOMEDRIVE\$HOMEPATH.
Currently only Posix and NT are implemented, a HomeDirError exception is
raised for all other OSes. """ #'
if os.name == 'posix':
return os.environ['HOME']
elif os.name == 'nt':
# For some strange reason, win9x returns 'nt' for os.name.
try:
return os.path.join(os.environ['HOMEDRIVE'],os.environ['HOMEPATH'])
except:
try:
# Use the registry to get the 'My Documents' folder.
import _winreg as wreg
key = wreg.OpenKey(wreg.HKEY_CURRENT_USER,
"Software\Microsoft\Windows\CurrentVersion\Explorer\Shell
Folders")
homedir = wreg.QueryValueEx(key,'Personal')[0]
key.Close()
return homedir
except:
return 'C:\\'
elif os.name == 'dos':
# Desperate, may do absurd things in classic MacOS. May work under DOS.
return 'C:\\'
else:
raise HomeDirError,'support for your operating system not implemented.'
