[python-win32] import and asp-python and iis - strange behaviour

[Simon Hook]

Steve,

Thanks for the quick response, everything you said works, I have a 
couple more questions. Here are a couple of scripts that illustrate how 
I implemented your suggestions.

-------file1 listing ---------------gofetch.asp
<%@ LANGUAGE = Python%>
<%
import sys
path = "d:/inetpub/wwwroot"   
sys.path.append(path)

import somefunctions
reload(somefunctions)
from somefunctions import *
%>  
<%=returnthevalue("okay it works")%>
-------------------------------------

-------file2 listing --------- somefunctions.asp
def returnthevalue(thevalue):
    return thevalue
------------------------------------

Both files go in the wwwroot directory. Now you see how bad I am at 
python, my two additonal questions are:
1) How can I avoid using an explicit path specification 
"d:/inetpub/wwwroot" I tried using os.getcwd() but that returned a 
system directory.
2) How can I avoid the 2 import calls for somefunctions. If I just use 
"import somefunctions" then I have to call the function as 
somefunctions.returnthevalue. But if I just use "from somefunctions 
import *" then reload does not work!

Thanks and great acronym BTW I had never heard that one.
