Any ideas what I'm doing wrong? It is possible that the python.org installer didn't overwrite the "python24.dll" in the system directory (C:\WINDOWS\system32). Try doing this: - manually delete C:\WINDOWS\system32\python24.dll - run the "repair" functionality of the python.org installer (you can either do this from "Start | Settings | Control Panel | Add/Remove Programs" or by just running the .msi file again Then try running python again.

This is probably a gross hack, but then I think one could argue that the
one-time "No handlers could be found for" warning is a misfeature -- at
least without a clean way to suppress it. I don't know the history of
that warning though:
-- mylib.py ---
import logging
log = logging.getLogger("mylib")
def func():
log.warn("don't go near the river")
log.error("I'm drowning!")
--
-- myscript.py ---
import sys
import logging
import mylib
if __name__ == "__main__":
if "-v" in sys.argv:
logging.basicConfig()
else:
logging.Logger.manager.emittedNoHandlerWarning = True
mylib.func()
--
$ python myscript.py
$ python myscript.py -v

Yah. My guess at what he is doing (and the way I'd probably do this for
Python) is to compile each statement, only allow certain constructs
(like assigning to a variable, defining literals, basic operator usage,
maybe some control flow statements -- although I didn't get that far)
and then execute those.

Re: Hash of class from instance
Joakim Storck wrote:
> [...] the hash values of classes will be used as
> keys in a dictionary that serve as an object pool. [...]
That does seem unwise (as Teal'c would have uttered). The spec says:
hash( object)
Return the hash value of the object (if it has one). Hash values are
integers. They are used to quickly compare dictionary keys during a
dictionary lookup. Numeric values that compare equal have the same hash
value (even if they are of different types, as is the case for 1 and
1.0).
Normally the following should hold (not mentioned in the above spec but
true for Java, e.g.): if a and b are objects such that a equals b then
hash(a) equals hash(b). This does not imply that if hash(a) equals
hash(b) also a equals b. More formally: (a == b) -> (hash(a) ==
hash(b)).
In Python there seems to be no guarantee that different objects also
have different hash values. So let's assume we have class objects Foo
and Bar, which by some unlikely incident happen to have the same hash
values, then storing them in a dictonary under their respective hash
values (which are identical) would most probably lead into a problem,
secifically the problem that you'd end up accessing Foo when you indeed
think you are accessing Bar, or vice versa. Just try this:
>>> my_pseudo_hash_code = 1
>>> my_dict = {my_pseudo_hash_code:"gnarf",
my_pseudo_hash_code:"snarf"}
>>> print my_dict

ANN: ActivePython 2.4.1 for Solaris 10 on SPARC, x86 and x64 systems
I'm happy to announce that ActivePython 2.4.1 for Solaris 10 on SPARC, x86 and x64 systems is now available for free download from: http://www.ActiveState.com/Products/ActivePython/ This release adds support for Solaris running on x86 and x64 systems. Note: This release (build 247) also includes important updates for the recently released ActivePython for Mac OS X. Please see the release notes for details. http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/relnotes.html#release_history What is ActivePython? - ActivePython is ActiveState's quality-assured binary distribution of Python. Builds for Linux, Mac OS X, Solaris and Windows are made freely available. ActivePython includes the Python core and core extensions (zlib 1.2.1, bzip2 1.0.2, bsddb 4.2.52, Tk 8.4.9, and Tix 8.1.4) and is fully compatible with other Python distributions of the same version. ActivePython also includes a wealth of Python documentation, including: - the core Python docs; - Andrew Kuchling's "What's New in Python" series; - the Non-Programmer's Tutorial for Python; - Mark Pilgrim's excellent "Dive into Python"; and - a snapshot of the Python FAQs, HOWTOs and PEPs. An online version of the docs can be found here: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/welcome.html Thanks, and enjoy!

The canonical way is using the Window API SHGetFolderPath function with the CSIDL_APPDATA key: from win32com.shell import shellcon, shell print shell.SHGetFolderPath(0, shellcon.CSIDL_APPDATA, 0, 0) This requires the PyWin32 extensions (which you already have if you have ActivePython installed). Alternatively you could write your own little C extension to call this Window API function... but you didn't want to do that. You can also call this WIndows API function (in the shell32.dll) with the Python "ctypes" modules out there.

What version did you install? I.e. what was the package name. Or do
this:
$ python
>>> import activestate, pprint
>>> pprint.pprint(activestate.version_info)
What version of Solaris do you have? Run:
uname -a
Do you get an error doing the following minimal Tkinter test:
>>> import Tkinter
>>> Tkinter.Tk()

Something to consider that would help to get the logging package more used would be to write up your experiences with it: write a tutorial or HOWTO or improvements of the core logging docs. Currently the logging package looks fairly uninviting/untractable to new users. Cheers Trent -- Trent Mick [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list

Yes. I was also trying to encourage Rotem to get involved in other parts

Yah, you are probably right. Most additions to the logging system could
easily live as their own separate pieces.

I'm not defending the implementation, but does this cause any particular
problems?

Maybe. Unless that causes troubles for real use. Having lazy
configuration like this means that it can be a subtle thing for
top-level application code to setup the proper logging configuration.
I cringe a little bit when I see this presented as the "hello world"
example. My basic hello world tends to be:
import logging
log = logging.getLogger("name-of-my-module-or-script")
# use log.{debug|info|warn|error}() in module/script...
#...
if __name__ == "__main__":
logging.basicConfig()
#...
and then I wish again that the default output were a bit nicer for my
most common usage -- which is logging to the command line in scripts --
rather than looking more like to web server error/access logs.
I think the usability of the logging module could be much improved with
a nicer introduction to it (i.e. docs). It's not really a "hello world"
type of tool. Its usefulness only really shows in larger use cases.

Perhaps Vijay (who did all the implementation) can comment on these.
Unfortunately backwards-compat might restrict some cleanups to the
package, but perhaps not too much. I did a poor job of keeping up with
the package after I laid out an initial design, er copied an initial
design from Java's log4j package (and I'm not even a Java guy). :(

Unfortunately your getting caught by the default logging level being
WARN, so that any log level below that is tossed.
import logging
logging.basicConfig()
logging.error("help!")
logging.warn("stay away from the river")
logging.info("nice sunset, eh?")
Running that generates:

Sort of. I guess all it implies is that if application code wants
to do special log handler setup then it needs to make sure to work in
the case of basicConfig() having been called and not.
The configuration stuff is quite subtle. The docs need to give
good best practices for a could coverage of reasonable use cases.
Nothing catastrophic will happen with a weird logging configuration --
probably just more log messages that you'd want.

Do you mean naming like "makeLogRecord" etc? I thought PEP 8 said
camelCase (or whatever it is called) was okay?

It isn't just the drive letter you shouldn't hardcode. In different
locales the phrases "Documents and Settings" and "Application Data"
are often different. The canonical way to get this dir on Windows is by
using the SHGetFolderPath Windows API call with the CSIDL_APPDATA
constant:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/reference/functions/shgetfolderpath.asp
In Python code that is:
from win32com.shell import shellcon, shell
path = shell.SHGetFolderPath(0, shellcon.CSIDL_APPDATA, 0, 0)
Unfortunately that either means having the PyWin32 extensions installed
(which not all Python installations on Windows have) or building your
own small binary extension to make that call. Failing that, using the
registry location or the environment variable above might suffice
Note that on some older Windows flavours -- not sure exactly which --
the APPDATA env. var. might not be defined.
Also note that Windows app guidelines encourage you to have an
additional vendor/owner directory level before the app name. So:
%APPDATA%\\Bombz
I have a little working script that I use for this kind of stuff which
you are welcome too, if it helps. (attached)

Re: Python Cookbook, 2'nd. Edition is published

Here is an excerpt from the preface (typing errors are mine): If you already own the first edition, you may be wondering whether you need this second edition, too. We think the answer is "yes." The first edition had 245 recipes; we kep 146 of those (with lots of editing in almost all cases), and added 192 new ones, for a total of 338 recipes in this second e4dition. So, over half of the recipes in this edition are complete,ly new, and all the recipes are updated to apply to today's Python -- releases 2.3 and 2.4. Indeed, this update is the main factor which lets us have almost 100 more recipes in a book of about the same size. The first edition covered all versions from 1.5.2 (one sometimes earlier) to 2.2; this one focuses fimly on 2.3 and 2.4. Thianks to the greater port of today's Python, and, even more4, thanks to the fact that this edition avoids the "historical" treatises about how you had to do things in Python versions releases 5 or more years ago, we were able to provide substantially more currently relevant recipes and information in roughtly the same amount of space.

By "failed" you mean the checksum is different? The file itself (if it
is a text file) might very well have different content: EOL characters
are different on Windows (CRLF) and Unix (LF). If a text file is opened
in textmode (the default), then the CRLF's will get translated to LF's,
however, if opened in binary mode (by having a 'b' in the mode option to
open()/file()) then this translation is not done.
Also, any reason you are not just using the hexdigest() method in the
md5 module?

Trent

I suspect that you are misinterpreting failure as success here. This is
probably only resulting in a bell from the shell when it complains that
it doesn't know of any command called "\a" to run.

You might be able to use or borrow code from my process.py module. process.py is very similar to Python 2.4's subprocess. It provides a ProcessOpen class (similar to subprocess' Popen). A ProcessOpen instance has wait() and kill() methods that work fine on Windows. Under the hood they are using the Win32 API WaitForSingleObject() and TerminateProcess() functions. http://starship.python.net/~tmick/ Yes, I haven't updated process.py in a while. :) It works fine with Python 2.3 and 2.4 (despite only saying Python 2.2 there).

George,
My suspicion is that the difference is that you are using a Cygwin
Python and it is using Un*x-style process return values. What do the
following return for your Python.
For me on Windows (with ActivePython 2.4):
>>> import os
>>> os.system("exit 0")
0
>>> os.system("exit 1")
1
And on Linux:
>>> import os
>>> os.system("exit 0")
0
>>> os.system("exit 1")
256
My cygwin Python is currently busted for some reason, so I can't test it
on my system.
On Unix-y/posix-y systems the retval from a process encodes both the
exit status and information on how the process was stopped (c.f. the
os.WIF* methods).
It would be helpful if you could log a bug for this in Komodo's bugdb so
we can track this and make sure it doesn't get lost:

Lists inside dictionary and how to look for particular value
z={ 'PC2': ['02:02:02:02:02:02', '192.168.0.2', '200'],
'PC3': ['03:03:03:03:03:03', '192.168.0.3', '200'],
'PC1': ['01:01:01:01:01:01', '192.168.0.1', '200'] }
My solution:
z=raw_input("Enter Host, Mac, ip and time")
t=z.split()
t[0]=z[1:]
for key in dic:
if t[2] in dic[key]:
del dic[t[0]]
else:
dic[t[0]] = t[1:]
What I really want to achieve is:
How to search for a particular value inside list. First, I want the user to
input hostname and ip. e.g. PC1 and 192.168.0.1, then need to find out if
192.168.0.1 has already been assigned to some host in dictionary. In this case
I would need to skip for search inside list of user input host.
Forexample, if user inputs PC1 and 192.168.0.1 i would like to skip searching
in above PC1's values. So it should detect matching only with different hosts
and skip its own name.
If i input PC4 and 192.168.0.1 then it should detect conflict with PC1. So PC4
would be deleted(As soon as user inputs new host it is saved in above database
then if conflict with others deleted)

Re: Difference between ActivePython and Python.org
[S.Chang wrote] > Anyone knows the difference(s) between the Python binaries from > ActiveState and Python.org? The responses to this thread so far gave most of the differences. In summary: - On Windows, ActivePython includes the PyWin32 extensions. - ActivePython rolls the core Python docs and a bunch of extra doc bits into one package, as detailed here: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/about.html - We have binary installers for more platforms: win32-x86 linux-x86 macosx-powerpc solaris-sparc solaris-x86 hpux-parisc aix-powerpc (And we'll likely have a few more in the future, in particular macosx-x86 and perhaps some newer 64-bit platforms.) - As Neil pointed out, ActivePython does not currently have SSL bindings (the _ssl module) that python.org's Python builds do. We are currently going through the legal hurdles so that we can include those. I expect that by or before the Python 2.5 timeframe we'll have _ssl in ActivePython. - ActivePython is free, but is not open source so, as Steve mentioned, you need permission if you want to *re-distribute* ActivePython. However, *using* ActivePython is still completely free and using tools like py2exe and py2app to wrap up your scripts and distribute those is fine. - ActivePython provides a Windows "debug" package: a zip of the debug-build libs that you can install into your Python install (python.org installs to as of the next release[1]). This can be useful for some people building debug builds of Python extensions. One of the important things is how ActivePython is NOT different: ActivePython should be fully binary compatible with python.org builds. This is to ensure that 3rd-party extensions built for and tested on one will just work on the other. [BartlebyScrivener wrote] > The ActiveState version lags behind for a month or two in versions, That is occassionaly true, yes, but not always.

I do basically this with a script I have (http://trentm.com/projects/go)
for doing exactly what Andy requested: changing directories.
On Un*x you setup a shell function (like an alias),
which calls the Python script go.py,
which writes a shell script that changes the directory,
which gets 'source'd by the shell function.
function go ()
{
go_is_on_path="`\which go`";
if test -e "$go_is_on_path"; then
export GO_SHELL_SCRIPT=$HOME/.__tmp_go.sh;
python `\which go` $*;
if [ -f $GO_SHELL_SCRIPT ]; then
source $GO_SHELL_SCRIPT;
fi;
else
echo "ERROR: could not find 'go' on your PATH";
fi
}
On Windows 'go' does the same thing with a batch file.

The problem is that when you run your script under the debugger (same thing with pdb.py) __file__ isn't set automatically because running a Python script with Python's execfile() (which is what Komodo debugger does) works slightly differently that what Python's main() does to run a Python script. One of the differences is the setting of __file__. (Side note: I'm not sure if this should be a Python bug or not. The intention of under what conditions __file__ should be set are not clear from the Python docs. From a quick poke I think it may be possible that __file__ not getting set via execfile() is a bug that was introduced with pythonrun.c changes when nested scopes were added a while back). We've started a bug for this on Komodo: http://bugs.activestate.com/Komodo/show_bug.cgi?id=43703 ...and Shane just fixed it. I.e. Subsequent releases of Komodo will have this fixed: __file__ will be set in the main module. Until that release, workarounds: 1. get the main script path from sys.argv[0]; or 2. apply the patch (to .../dbgp/client.py in your Komodo install) that Shane attached to that bug to your Komodo installation.

Basically there is a string entry in that table that is used as part of the registry path for registry usage.

That "X.Y" string is what determines that part of the registry lookup path for: HKLM/Software/Python/PythonCore/X.Y/PythonPath - You could change the "Caption" value to "FuzzyWuzzyWuzzaBear" to effectively disable usage of the registry for sys.path building by that pythonXY.dll.

If you just want to check if winver.exe exists you could just try

(likely "C:\Windows\system32") or you could use which.py:

By my count: ActivePython-2.4.2.10-win32-x86.msi 19,053 KB ActivePython-2.4.3.12-win32-x86.msi 19,237 KB Note that the Windows *64-bit* builds are smaller (around 15MB) because they do not include PyWin32.

Ah, the PythonWin IDE/Editor is part of PyWin32 -- which is included as a standard part of ActivePython. IDLE is also included in ActivePython, BTW. ActivePython just doesn't setup a shortcut in the Start Menu for it. You could add your own. As jean-marc suggests, you might want to search the python-list archives for peoples opinions on Python IDEs and editors. Also check out: http://wiki.python.org/moin/IntegratedDevelopmentEnvironments http://wiki.python.org/moin/PythonEditors ActiveState has a Python IDE called Komodo http://www.activestate.com/Products/Komodo/ which I work on (so I'm biased :).

No. But you'll have to get comfortable building your own Firefox and then building the PyXPCOM extension and then packaging the built PyXPCOM bits that a normal Firefox install does not have already into a Firefox extension. This would also mean packaging up parts of a Python build and possible needing to have a custom Python build to (1) get shared library loading to work correct and (2) ensure there isn't crosstalk between the python that PyXPCOM uses and possibly other Python installations on the target machine. > This is less a python issue clearly if that is the case: would I have > the same issues to resolve if I were to write the module in C++ ? A little, yes: I believe you'd need a Firefox build in a development tree to build a vanilla C++ XPCOM component. However, I am not sure of that. Mostly, no: You wouldn't need to worry about all the PyXPCOM/Python build/install issues. Trent -- Trent Mick [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
ANN: ActivePython 2.4.2.10 is now available
I'm happy to announce that ActivePython 2.4.2.10 is now available for free download from: http://www.ActiveState.com/Products/ActivePython/ This release is a maintenance/update release for existing platforms and adds support for three new ones: Mac OS X/x86, Windows/x64 and Linux/x86_64. See below for a full list of supported platforms. Changes in this release include: - Add early support for Mac OS X for Intel platform (macosx-x86). Please see the "Mac OS X for Intel" section below for details. - Upgrade to PyWin32 build 207 on Windows/x86 - Upgrade Tkinter to Tcl/Tk 8.4.12 - Support for Windows/x64 (win64-x64). Note that PyWin32 has not been ported to 64-bit Windows so this build does not include PyWin32. - Support for Linux/x86_64 (linux-x86_64) - Fixed a problem on Mac OS X/PowerPC that unintentionally created a dependency on Fink (fink.sourceforge.net) for the "bz2" and "curses" extensions. (Thanks, Bob!) - The Windows "debug libraries" package now allows installation into non-ActivePython Python installations of the same version. This was requested by Dave Abrahams for the Boost folks (http://tinyurl.com/898zw). - Changed Intel 32-bit architecture platform name from "ix86" to "x86", changing package names for some ActivePython builds. Mac OS X for Intel -- This is the first release of ActivePython for Mac OS X/Intel. It should be considered an early release. This build is not a universal build and there are a number of known issues: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/relnotes.html#KI_macosx I suspect that ultimately a universal Python build is the right answer, but details and issues around that should be discussed on the Python Mac mailing list: pythonmac-sig@python.org What is ActivePython? - ActivePython is ActiveState's quality-assured binary distribution of Python. Builds for AIX, HP-UX, Linux, Mac OS X, Solaris, and Windows are made freely available. ActivePython includes the Python core and core extensions (zlib 1.2.3, bzip2 1.0.2, bsddb 4.2.52, Tk 8.4.12, and Tix 8.1.4) and is fully compatible with other Python distributions of the same version. ActivePython also includes a wealth of Python documentation, including: - the core Python docs; - Andrew Kuchling's "What's New in Python" series; - the Non-Programmer's Tutorial for Python; - Mark Pilgrim's excellent "Dive into Python"; and - a snapshot of the Python FAQs, HOWTOs, and PEPs.

ActivePython now includes installers for the following ten platforms: - AIX/PowerPC - HP-UX/PA-RISC - Linux/x86 - (new) Linux/x86_64: "x86_64" is also known as "AMD64" - Solaris/SPARC - Solaris/x86 - Mac OS X/PowerPC - (new) Mac OS X/x86: - (new) Windows/x64: "x64" is also known as "AMD64" - Windows/x86 Extra Bits -- ActivePython releases also include the following packages: - Windows "debug" package: Debug-built binaries for ActivePython users building debug versions of their binary Python extensions. - ActivePython24.chm: An MS compiled help collection of the full ActivePython documentation set. Linux users of applications such as xCHM might find this useful. This package is installed by default on Windows.

That is correct. More details here: http://mail.python.org/pipermail/python-list/2005-December/315754.html ... - As Neil pointed out, ActivePython does not currently have SSL bindings (the _ssl module) that python.org's Python builds do.

Nope. Komodo adds no goo to your code (TM). TM's my name, not a trademark on "Komodo adds no goo to your code" -- but I'm thinking about it. :) Perhaps you are thinking of some of the C/C++ IDEs (like Visual Studio on Windows and Xcode on the Mac) that will help you setup of projects using their build systems that sometimes imply a number of standard files. Komodo doesn't mandate a build system. > Any other thoughts on Komodo? I am considering it because I am hoping to find > a solution to the install-packages-until-you-go-blind aspect of Python. > Setting up a serious, cross-platform, gui development environment is quite a > struggle for a newbie. Not sure about the "install-packages-until-you-go-blind" thing. Komodo doesn't help you install packages into your Python implementation. Nor does Komodo have front-ends to py2app or py2exe for wrapping up Python code into standalone executables. GUI development, however. Komodo's GUI Builder is intended to be a GUI designer for simple Tkinter-based UIs. It does mandate a certain style for your *GUI* code, but I believe that all GUI designers need to do this. Because I work on Komodo I am biased, so won't give you an opinion on it relative to other tools out there.

Unfortunately ActivePython cannot include the SSL library by default
because of crypto export regulations. For SSL support in an ActivePython
installation you'd have to add the _ssl.pyd extension separately (either
building it yourself, or finding an available binary).
