problem using py2exe
by Ho-Kyeong Aug. 1, 2005

Aug. 1, 2005

Can anybody give me a detailed explanation of using extension modules in py2exe? My python code imports 'tkSnack', a extension module, and my setup.py is like this: #setup.py from distutils.core import setup import py2exe setup(name="pitch", scripts=["pitch.py"] ) (that is, pitch.py imports tkSnack.) In cmd, I type 'python setup.py py2exe'. It works well, but I execute the pitch.exe, then error happens. Traceback (most recent call last): File "<string>", line 14, in ? File "<string>", line 7, in pitch File "tkSnack.pyc", line 21, in initializeSnack TclError: can't find package snack I look up in python.org, but I have no idea.

Hi, If I have a Windows DLL file, how can I retrieve its version number (e.g.: 2.40.4275.1)? Does Win32 extensions, ctypes or related modules provide such a utility? regards, Hung Jung

webGobbler
by gg20040914.20.sebsauvage＠spamgourmet.com March 21, 2005

March 21, 2005

Hello, dear dear clp. The idea was bugging me, so I decided to code it: webGobbler is a small program which gobbles random pictures from the web and mixes them (This is inspired from 'debris' and 'webcollage'.). Think of it as some kind of "art", an attempt to capture the chaos of the human activity, which the internet is a partial and subjective snapshot of. webGobbler is a simple command-line program which spiders the web, collect images and assembles them in various ways. The images can be used - for example - as a desktop background changer. The image continuously evolves as new pictures are superposed. You'll never get the same picture twice. A screensaver is also planned (when I have time - *sigh*). The program is written in Python and requires the PIL library. This is perfectly useless, but I had fun creating this. You will find documentation, samples and source code here: http://sebsauvage.net/python/webgobbler/ Feel free to give it a try. This program is distributed under the zlib/libpng opensource license. Critics, comments and ideas are welcome ! Best regards. -- Sebastien SAUVAGE sebsauvage at sebsauvage dot net http://sebsauvage.net

newbie question
by David Wurmfeld March 15, 2005

March 15, 2005

I am new to python; any insight on the following would be appreciated, even if it is the admonition to RTFM (as long as you can direct me to a relevant FM) Is there a standard approach to enumerated types? I could create a dictionary with a linear set of keys, but isn't this overkill? There is afterall a "True" and "False" enumeration for Boolean. Is there a way to ignore case in string comparisons? I want 'Oranges' to equal 'oranges' when using the evaluation operator (==). I don't care about string inequalities (<, >) If I am compelled to use dictionaries for enumerated types, is there a way to generate unique keys automatically: something like "myDict.appendWithAutoKey("Persimmons")"? Is there a way to overload operators to accommodate an enumeration? For example, newFruit = enumerationFruit('Cumquat') #use it like you would use list() new = newFruit + 14 # this should throw an exception because of different types Finally, (for now at least) consider the following list. myList = [apple, 13, plum, cherry, 'Spam', tomato, 3.35] Exactly how does the "for x in myList" work? If the list is a heterogeneous list of disparate types, the == operator works fine, independent of type. For example, (if x == 'spam') evaluates as false if the item in the list is an integer. But if I try to do this: (if x.__abs()__) throws an exception if x "pulls" a non integer from the list. Wouldn't you think that an iterative would have the "sense" to understand that in this limited scope if a method didn't apply to the iterator just "fail" (i.e. evaluate to False) the evaluation and move along? Do I have to manually interrogate each iteration for the proper type before I test? Think about it; the interpreter has to evaluate disparate types for equality. How exactly does the it "know" that for this iteration, x is an integer, and the evaluation (if x == 'spam') is False, and doesn't throw an exception for a type mismatch? Thanks in advance for your insight, David, Melbourne, Florida.

help with warning formatting
by Mike Brown March 11, 2005

March 11, 2005

I'm trying to get the hang of warnings. % cat t.py import warnings warnings.warn('foo') % python t.py t.py:2: UserWarning: foo warnings.warn('foo') Is there a way to just issue the warning message itself, or to at least suppress printing the line where the warning occurred (" warnings.warn('foo')" in the example)? See, I want to warn the user of my application that they're doing something risky or improper, so I just want to emit the 'foo', subject to the usual determination of whether the warning needs to be printed at all. For my purposes, the user doesn't need to know where the warning occurred, and they certainly don't need to see pieces of the call stack. The way it works now, it seems to be intended to warn the application programmer that they're doing something risky in the code (?). Thanks in advance for any advice.

Win32 drive mapping... aka "net use"
by lshuler＠my-deja.com March 5, 2005

March 5, 2005

Is there an API using Win32 extensions to map a drive share? I have not found one yet and have tried searching "Win32 map drive". I am looking for the equivalent of: net use <share path> If not, is there an alternative other than making a call to system("net use <path>"). Thanks in advance, Lance Sent via Deja.com http://www.deja.com/ Before you buy.

Using PIL with py2exe
by John Carter Feb. 28, 2005

Feb. 28, 2005

Does anyone know how to embed PIL into a py2exe program. As far as I can tell PIL is not finding its plugins for Image I/O, they are imported dynamically as required. So I cant load or save pictures I tried making a copy of the plugin files to the application directory, but I've had no luck in making the code see the files I'd be grateful for any suggestion. Please e-mail me, as well as posting a reply. John Carter jnc(a)ecs.soton.ac.uk

Making pygopherd working with Mac OS X
by mattabat＠hotmail.com Feb. 23, 2005

Feb. 23, 2005

Hello, I attempted to use pygopherd 2.0.9 work with MacPython 2.3 under Mac OS X 10.3.7 but I'm afraid I hit a brick wall trying to make it run. Does anyone know how to make this work? I obtained pygopherd from gopher://gopher.quux.org/1/devel/gopher/pygopherd - or for the gopher client deprived, from http://gopher.quux.org:70/devel/gopher/pygopherd Has anyone managed to get pygopherd running with MacPython? -- mattabat

Problem using win32com
by unknown＠example.com Feb. 14, 2005

Feb. 14, 2005

Hi, A month ago, I decided to move from Delphi to Python/wxPython for a good deal of my development work, and for the past few projects (which included a full re-write of our point-of-sale system) I've had no problems and been very pleased with the move. We're Sage (accounting software) developers and frequently link into Line 50 using a Sage supplied COM server. In Delphi, the code to create the client and a workspace (which is required later) is as follows: SDO := CreateOLEObject('SDOEngine.10'); WS := SDO.Workspaces.Add('abc'); So naturally, I'd expect the following Python code to work: import win32com.client SDO = win32com.client.Dispatch("SDOEngine.10") WS = SDO.Workspaces.Add("abc") But at the last stage, I get an error: Traceback (most recent call last): File "<pyshell#4>", line 1, in -toplevel- ws=sdo.Workspaces.Add("ss") File "C:\PYTHON23\lib\site-packages\win32com\client\dynamic.py", line 154, in __call__ return self._get_good_object_(self._oleobj_.Invoke(*allArgs),self._olerepr_.defaultDispatchName,None) com_error: (-2147352573, 'Member not found.', None, None) So I used MakePy to generate the relevant Python interface code, and tried the following: SDO=win32com.client.gencache.EnsureModule("{ACE2C5EC-2EC0-4AEB-8B0D-27A5A1ED6421}",0,10,0) WS=SDO.Workspaces.Add("abc") But now I get: Traceback (most recent call last): File "<interactive input>", line 1, in ? TypeError: unbound method Add() must be called with IWorkspaces instance as first argument (got str instance instead) The relevant MakePy generated code looks like this: class IWorkspaces(DispatchBaseClass): CLSID = IID('{7075CC61-F056-11D0-A34B-000000000000}') coclass_clsid = IID('{7075CC63-F056-11D0-A34B-000000000000}') def Add(self, Name=defaultNamedNotOptArg): ret = self._oleobj_.InvokeTypes(2, LCID, 1, (9, 0), ((8, 0),),Name) if ret is not None: ret = Dispatch(ret, 'Add', None, UnicodeToString=0) return ret class Workspaces(CoClassBaseClass): # A CoClass CLSID = IID('{7075CC63-F056-11D0-A34B-000000000000}') coclass_sources = [ ] coclass_interfaces = [ IWorkspaces, ] default_interface = IWorkspaces What am I doing wrong? And more importantly, what can I do about it? I suspect there's a really simple answer which begins "Chris, you're being a fool...", but it's now pretty late, and I have other matters to deal with for the next few hours, so any help would be much appreciated. Regards, Chris
