[Zope] How can i call a pyhton module's function from with in Page Temmplates?

Hello, i saw that from within a DTML Method one is able to call a fuction of a python module in the file system. Now i want to get the funtion's results from within a Page Template. Is the right way to make a Script(Python) that calls this module's function and then call this Script(Python) from within my Page Template? Is there any other less nifty way to do this? Thanks in advance. ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
