You probably want to take a copy of interp.py and modify it so that when a
dictionary is returned, you return something like the Python.Dictionary
object (see win32com\servers\dictionary.py). You can create such an object
via something like:
>>> from win32com.servers.dictionary import DictionaryPolicy
>>> from win32com.server.util import wrap
>>> ob = wrap({"foo":"bar"}, usePolicy=DictionaryPolicy)
>>> ob
<PyIDispatch at 0x01507A88 with obj at 0x01511620>
If interp.py returned 'ob', VB should be able to access it somewhat like a
regular VB collection - so instead of simply:
return eval(str(exp), self.dict)
you checked the result, and if it's a dict, execute the lines above and
return 'ob' instead of the dict (and obviously using a real dict instead of
the constant one in the example above)
Hope this helps (and works ;)

Subject: Re: [python-win32] Executing eval function in VBscript
yes i want to have python functionality in excel,
iam trying to call python functions from VBscript,
more like evaluating a python expression say dictionary or list in VBscript
For evaluating a python expression , python has some library functions like
eval which takes python expressions
in string format and checks whether it is a valid python expression or not
so i thought of calling that python eval function in VBscript and validate
my datas
but the problem is when i tried to pass dictionaries for eg, "{'key':value}"
this is the format of dictionary in python
VBscript throws error like type mismatch
since VB dictionary representation of VB and python are different
Thanks and Regards!

I think he wants to have python functionality from excel, which is
what I'd like to accomplish as well.
(Python embedded into excel, as opposed to launching Excel from Python)

Everything you want to know about the MSScriptControl is on microsoft's
site.
