In an Python Script.
Normally, the python way would be: raise Redirect(url)
But for this, Redirect has to be a subclass of Exception.
I think there are historical reasons why all the Zope Exceptions
are Strings (String Exceptions are deprecated since Python 1.4)

However, if you are not familar with the concept of exceptions
and classes, please consult the very good python manuals
at python.org. The tutorial does it clear out quite good.

In your case:

raise 'Redirect',url

would work.
