There is an important difference between scripts and
modules.  A script is meant to be run as an argument
to python.exe (assuming you're on Windows because of
the backslashes:-).  A module is meant to be imported.
A foo.py file can be both, but adapting the path is
relevant to module-use only, NOT to script-use.  All
clear so far...?

For sys.path adaptation, simplest is to use .PTH files.

Any textfile with an extension of .PTH found in the
Python home directory (e.g. C:\Python20 in your case,
I guess) is read on startup: each line is the full
path of a directory to be added to sys.path (the .PTH
file may also include empty lines and comment lines
starting with #).
