The last remaining piece of the puzzle is to write the script that
will create a file and sets its contents and properties. We'll do
this in Python since it is much clearer than doing it in DTML. Create
a Python-based Script in the *GuestBook* folder called *addEntry*
with parameters *guest_name* and *comments*::
## Script (Python) "addEntry"
Create a guest book entry.
# create a unique file id
id='entry_%d' % len(context.objectIds())
# create the file
# add a guest_name string property
doc.manage_addProperty('guest_name', guest_name, 'string')

Where does the ['OFSP'] come from?
After digging around and doing a few searches, I found it's a core part of
Zope, but no explainations.

I get an error that states:
Error Type: TypeError
Error Value: addEntry() takes no arguments (2 given)
What did I do wrong?

You forgot to include the parameters for the Python script in the Parameters field when pasting the script
into a new Python Script object. You need to explicitly state what parameter your python 'function' takes
when creating the script.

Does 'doc=getattr(context, id)' returns an instance of the file object class? What if there's another way of
getting the instance of that object, can we use it to call the method 'doc.manage_addProperty'?
