Small variation on the above patch, using 2 environment variables:
PYTHONSITEDIR allows for local site-packages (that override system
site packages), and PYTHONNOSYSSITES skips system site-packages for
"clean-room" operation (similar to virtual-python.py --no-site-
packages).

Dear all,
These days I often find myself using working-env.py, virtual-python.py
& co. The main reason in most cases is to insulate my working
environment so that I can use custom site-package libs together with
the default stdlib. PYTHONHOME and/or PYTHONPATH (particularly with
python -S) get clo
ironments where there is a clear
separation between IT and developer roles.
I just started giving some thoughts to the concept and I am not fully
aware of the implications and requirements of the proposal, but even
if the above turns out to be impractical, I hope that a debate on the
topic will be b
I have started using the enum module () , at them moment pickling an
object instance that has an EnumValues assigned to one of its
attributes pickles the full enumeration, this is not efficient. I am

to use __getstate__/__setsta

solved, if it can be useful to others here is my code:

def getWorkbook(workbookName):
lenstr = len(workbookName)
workbook = None
rot = pythoncom.GetRunningObjectTable()
rotenum = rot.EnumRunning()

The other approach I tried (as suggested by Tim, thanks) involves
browsing the ROT.

SPREADSHEET_NAME = r'\MySpreadsheet.xls'

The following seems to do the trick:

WINDOW_CLASS = 'XLMAIN'
WINDOW_TITLE = 'Microsoft Excel - MySpreadsheet.xls'
hwindow = win32gui.FindWindow(WINDOW_CLASS,WINDOW_TITLE)

Hi all,
When I use my win32com.server object from an excel client, the python
process running the server always has __debug__==True. When using a
python client the __debug__ flag for the server is determined by the
client (i.e. if I start the client with 'python -o client.py' then

I solved it. If someone else is in the same situation...
It was due to a defective installation. I reinstalled python and pywin,
re-registered the server and everything worked well.

Well, I started from the reduction-only algorithm so by the time I

Anton,
Do you think it is possible to reduce the set of all possible solutions
to a small enough set? I personally doubt it, but IF that was the case
an efficient solver could be easily created.
In reducing the set of all solutions for instance you could always swap
the numbers (3rd axis) so that

Thanks for the nice problem and the nice post.

Inspired by some recent readings on LinuxJournal and an ASPN recipe, I
decided to revamp my old python hack... The new code is a combination
of (2) reduction methods and brute force and it is quite faster than
the
ASPN program. If anyone is interested I attached the code in

In fact even IF I could get a default value to work as mentioned, then
I would be creating potential name conflicts between the
DataAttribute.DefaultValue and the other metadata. I.e. when calling
obj.attr.x I could refer to DataAttribute.x or DataAttribute.value.x.
It's a no go.

You probably nailed it, thanks for the answer. I suspected that was the

I am trying to write a generic DataAttribute class in order to simplify
access to object attributes and attached attribute-metadata for end
users with little programming experience.
Requirement 1: accessing the "default" value should be easy (using
assignment operator, via descriptors like __get__
The print statement was only for illustrative purposes, when calling
varx=myobj I need to receive obj.x as opposed to the instance of obj,
but I also need to call vary=myobj.y. Something like that exists for
com objects/VB, for instance an excel range object uses value as the
default attribute, so
Is it possible to have a default value associated python objects? I.e.
to flag an attribute in such a way that the assignment operator for the
object returns the default attribute instead of the object itself, but
calls to other object attributes are properly resolved? (I don't think
so, but I am n
