Re: XML-RPC server-client communication

Could it be that xxx.xxx.xxx.xxx stands for '127.0.0.1'? If so... rename
it to 'localhost'. If you bind a port to 127.0.0.1 it will be found only
on the same machine.

pyExcelerator - Can I read and modify an existing Excel-WorkBook?
Hi I would like to 1. import an existing Excel-sheet (a template) 2. and add some data to it 3. and save it under a different name afterwards. To me it seems, that pyExcelerator does not support the reading for modification of an Excel-sheet. It allows only the "parse_xls" but I would like to keep the "formatting" in the template. Did I miss a "load", "read" or "open" function in pyExcelerator that would hand me back a WorkBook? Greetings, Marco -- http://mail.python.org/mailman/listinfo/python-list
Re: Looking for an intellisense with good help IDE for Python
The best code completion you can get for Python is delivered by WingIDE: http://wingware.com/ I have seen, PyDev, Kommodo, Spe and when it comes to code completion for Python than nothing beats WingIDE. Maybe anyone can proof the contrary. WingIDE is not for free though (Personal: 35 USD upto Profession: 180 USD) - you can download a fully fuctional version and prolong it a few times... try it out, if you are willing to pay a few bucks.

Using "external" vars on module load time
Hi
I have a script that looks for modules and tries to load them. After
loading I attach the "server"-API function to it.
module = __import__(module_name, globals(), locals(), [])
module.server = server.server_api
Now, some modules need the "server" functionality on load/init. I tried to
modify the globals():
my_globals = globals().copy()
my_globals['server'] = server.server_api
module = __import__(module_name, my_globals, locals(), [])
module.server = server.server_api
This did not work as intended the module to be imported did not get the
"server" from my_globals. The solution I have, is to add __init_module__()
method that is called after the module was imported:
module = __import__(module_name, globals(), locals(), [])
module.server = server.server_api
if module.__dict__.has_key('__init_module__'):
module.__init_module__()
This is not really satisfying. I would like:
Load a module and hand in already the server_api. How can I achieve this?
Thanks for any suggestions,
Marco

The del statement
Hi I was wondering whether the del statment was going to stay in Python3000? It is a bit awkward to use the del statement where a method call would do the same without the need for a new keyword. del list[elem] del map[elem] Where list.del(elem) map.del(elem) would achieve the same result (and I think, this is what happens in the backend). The same discussion was done for the "external" len-function (list.len() vs. len(list)). I don't dare to say that the del-keyword is superflous, but I would like to know the pros and cons of the external keyword approach. Greetings, Marco -- http://mail.python.org/mailman/listinfo/python-list
Re: The del statement
> so what about > > del x Ups. I never used it for an object. So far I only used it for deletion of elements of a container. In that case del has two purposes: 1. Deletes an item from a container (and of course destructs it) --> list.remove(elem) 2. Calls the destructor of an object --> list.destruct() One statement and two distinct purposes. Why not having two "standard" function (for containers we have a remove-function) and all objects have a destruct-function. Still no need for a del keyword. A del keyword that calls the destructor... well that is okay (it could be handled without). I am used to see the del keyword in opposition to the new keyword (which does not exist/is implicit in Python). The del keyword for removing an element in a container is a bit awkward to me. I am not as knowledgeable about languages as you are and I am hoping people like you can enlighten me about the language decision taken. > for the curious, guido's rationale for len() can be found here: > >http://preview.tinyurl.com/y6vavp Thanks for the hint.

Re: The del statement
> do you find the x[i] syntax for calling the getitem/setitem methods a > bit awkward too? what about HTTP's use of "GET" and "POST" for most > about everything ? ;-) No. I like the x[i] syntax. I use it in every second row of my code and getting an item like: x.getitem(i) would be a viable (in this case clumsy) way but here I find the introduced syntax justified. del on the other hand is used sparingly througout my code. If no del keyword would exist, it wouldn't disturb me. Marco -- http://mail.python.org/mailman/listinfo/python-list
Re: The del statement
Thanks for the answers. I see that the del statement does remove an object from the namespace. And yes, it makes perfect sense to handle it from "outside" with the del command. I am not convinced though that del should also remove elements from a container/sequence. Thanks for the enlighting answers, Marco -- http://mail.python.org/mailman/listinfo/python-list

Re: Python and Lotus Notes
The second line of your code is already a show stopper in my case:

PyExcelerator - mishandling of formulas?
Hi,
Yesterday I placed a bug report on PyExcelerators-Sourceforge-page... but
I am not so sure anymore, whether this is really a bug - I could imagine
that I missed something, but I don't see what. Please confirm that my bug
is due to mishandling and I will gladly retreat my bug report.
In a formula, I would like to point to a field on another worksheet.
pyExcelerator chokes on these references!
import pyExcelerator
wb = pyExcelerator.Workbook()
ws_summary = wb.add_sheet('Summary')
ws_data = wb.add_sheet('Data')
ws_summary.write(0,0, pyExcelerator.Formula('Data:A1')) <--- Here it
chokes!
ws_data.write(0, 0, '4000')
wb.save('not_parsing.xls')
Is this a bug or am I doing something wrong?
Regards,
Marco

Right you are. It "changed" somehow... anyhow, even if you change it, it
will choke on the same line. I received an answer... a workaround which
doesn't make me happy, but it is, as it is!
[...]
This is not a bug. This is by design. pyExcelerator does not
unerstand such syntax. Try Formula("HYPERLINK(address; name)")
[...]
Which means:
ws_summary.write(0,0, pyExcelerator.Formula('HYPERLINK("Data!A1"))
does the trick, but the text shown is a hyperlink now!
Thanks for your help,

Re: Winge IDE Issue - an suggestions?
Without further checking I would propose you let WingIDE ignore this exception - most probably WingIDE is choking on a exception that was thrown intentionally by the module writer.

Re: Batteries Included?
> I might be wrong expecting that a language whose > moto is "Batteries Included" would be able to produce exe files. Are > there plans to do this in the future version of Python? Yes, you are wrong expecting that. Creating an exe-cutable is windows specific and python _tries_ to be platform neutral. py2exe - a wonderful tool which I use myself - is a battery on the shelves. It can be easily picked from there. Furthermore it is not Python's philosophy to create "exe-cutables". But I do understand your wish (being a Windows Developper at work myself) and Python is not a matter of course within Windows. Your best bet is ActiveState which bundles a windows specific version. Ask them, maybe they are willing to include it. Python should refrain from doing so. Before overloading the "included batteries" an approach as found in Perl (CPAN) should be adapted... eg. http://peak.telecommunity.com/DevCenter/EasyInstall Have a nice day, Marco -- http://mail.python.org/mailman/listinfo/python-list

COM on a network drive can't find pywintypes23.dll
Hi I have installed Python (2.3.4) on a shared network drive. I use it to run a bunch of application on the workstations (Win2K). Now I am running into the first problem ever. I try to use COM to generate a word-file. It runs fine on my machine (Python installed locally). When I deploy it and start the app on another workstation from the fileserver - it runs but as soon as it comes to the COM part it exits saying: The procedure entry point ?PyWinObject_AsDEVMODE@@YAHPAU_object@@PAPAU_devicemodeA@@[EMAIL PROTECTED] could not be located in the dynamic link library pywintypes23.dll Heck... I copied the files: pythoncom23.dll pywintypes23.dll to about "1000" locations to make it run (Application's dir, Workstation's System Dirs, Fileserver's Python main and bin dir, ...). I tried setting the path on the workstations. But nothing seems to solve the problem. Do you have any proposals how to solve this problem?

From Python to c++
This is actually a c++ problem. Got no satisfying answer on comp.lang.c++.
Maybe you can help better because I know, there are many c++-converts ;).
Suppose you've got the following list (first line has field names, second
line has types and any row after is data):
csv = "name,age,place\nstring,int,string\nMac,25,Zurich\nMike,55,Oslo"
and you would like to turn it into a dictionary:
parsed = {
"name":["Mac", "Mike"],
"age":[25, 55],
"place":["Zurich", "Oslo"]
}
A trivial task in Python. In C++ it is cumbersome. I was thinking to put
the parsed data into a map:
map >
I have no problem with the key (string) but the value (vector) needs to be
of varying type. I think C++-STL does not allow what I want.
The following proposal is useless:
[...]
A simple solution, make two maps:
std::map > result_name;
std::map > result_age;
[...]
I want to build the map of lists dynamically - it can have many fields or
just one... and I would like to have simple interface (as Python offers).
- I cannot import python into the c++ environment (Borland Developer 2006)
and I know no one who was able to.
- I cannot write (*sigh*) the app in Python.
Any suggestions are very welcome!

Marco (Forced to code in c++ again let me estimate the simplicity of
python)
