Well, I did it: from App.config import getConfiguration extPath = getConfiguration().instancehome+'/Extensions' if sys.path.count(extPath) == 0: sys.path.insert(0, extPath) And it worked for what I wanted. On 13/02/07, Alan <alanwilter@gmail.com> wrote:

What's the sense of this code? sys.path is usually *never* empty. You should really look at the Python docs and learn where Python is looking by default for modules. Is is perfectly documented -> python.org -> documentation.

In addition you would like to check for the existence of an item in sys.path using

if myPath in sys.path:

Dear Andreas and Jonathan, first a mistake: I want to access 'Extensions' folder as you mentioned Jonathan, not 'import'.

Andreas, I've done that, I can see several path there like .../instance/Products/Sprout/src, .../lib/python/Zope2/Startup etc., but none for .../instance/Extensions.

I was hoping that I could get the path where 'Extensions' is because I work with several zope installations in several platforms and I would like to make my module independent of a variable inside its code that should be manually adjusted for every situation.

And yes, I am aware about adding the path only once (that's why there's a 'if') and then I avoid recursive insertions.

Cheers, Alan
