Help installing Python 2.3 on Win2K

[D.S. Hein]

I have installed python 2.3 on my Windows 2K laptop and I can run python 
from the command prompt.

I have tried various ways to set PYTHONPATH with the various directories 
where I have python programs (i.e. xxxxxx.py) but no matter how I set 
PYTHONPATH I keep getting a message that python can't open the python 
file. If I try to specify the full pathname by typing: python 
c:\Documents and Settings\-rest of path- I get an error message that 
python can't open c:\Documents.

The ways I have set PYTHONPATH are by directly changing the registry 
entry for Python 2.3, by setting the environment variable by 
right-clicking on My Computer and by adding set PYTHONPATH=-various 
pathnames-.

I'd be grateful for any guidance on how to organize my system.
