[Zope] objects as values in a python dictionary

[Peter Bengtsson]

Thanks for the reply.

I'll satisfy with that as an answer for now, even though stuff in
objectValues() appear equally as complex as context or self or something
like that.

 I need to do this for a search function.
It recursivly loops through a couple of meta_type's (my ZClass objects)
including Folder and collects (in theory) a dictionary of objects and their
"search-match-result"
The resulting dictionary will look like this (again, in theory):
{<pobject at 74500>:3, <object at 05464>:1}
Where the 3 and 1 represents "points" derived from my special search
conditions.
If I just store the Id of each object, I'm also going to need the context it
has to be able to do:
print getattr(itscontext, thisid).title_or_id() # in zope

My alternatives are to store them like:
[[<pobject at 74500>,3], [<object at 93483>,1]]

I don't want to use ZopeFind because I want to have more defined control
over the arrangment of the search result.

Perhaps this will work:

{[<pobject at 74500>]:3, [<object at 05464>]:1}
...and then I can do has_key() still.
