The question is whicvh file?

Instead of telling us what you did it woyuld be more useful to cut n 
paste the actual command used into the mail (including the prompt since 
it usually shows which directory you are in)

That only helps with imports.

That will help Wiondows find python.exe but has no affect omn whether 
Windows can see foo.py

Notice that the error says it is foo.py that it cannot find.
You need to provide the path to foo.py (or change into the directory 
where it lives)

Thats because import uses the PYTHONPATH and your .pth file
to find files.

Windows doesn't know about them.

Incidentally the easiest way to run foo.py in Windows is simply to 
double click it in Windows explorer... Although you may need to add a 
pause line (eg raw_input("Hit enter to quit") ) at the end to see the 
output.
