[Zope] HELP: CST and python scripts

[Aseem Mohanty]

oh crap. i had a script that put in all form data into the session for 
error-tracking and I was inserting a file object in a file upload form 
to it too.

so how do I check if the object is a file or not in thte python script?

currently I do:

for key in form.keys:
    try:
        x = key.filename
    except AttributeError:
        data.set(...)

that seems to be the dumb way to go... is there any better way to do do it.
TIA
