You can get inspiration from the following code, but the problem is you

color.
I don't know any other way. However, I'm used to 2.6 and I could miss

This is amazingly hard to read. Can you please post your message

All the punctuation characters you're using have typographical

thread and processes with python/GTK
Hello,
I'm developping an application with python, pyGTK and GTK+.
I've performed many tests by using methods as Popen, popen2,
os.system ... to communicate with Unix (HPUX),
The last attempt is this code written in a thread :
fin,fout = popen2.popen2('ps -def')
line = fin.readline()
while 1 :
if not line : break
print "line=",line
line = fin.readline()
fin.close()
In that case, lines are printed only when I exit my application.
Usually the behavior is not as expected and I cannot understand why. I
am wondering that it could be a constraint from the use of GTK
(mainloop() existence ???).
Is somebody aware about conflict between GTK use and unix mechanism.
Thanks for you help

Re: error messages containing unicode
Thank you for the reply. It happens that, as I understand it, none of

But I often raise one of Python's built-in errors. And also, is it
really true that subclassing one of Python's built-ins give me
something that is unicode deficient? I assumed that I had missed
something (because that's happened so many times before :-) ).
For instance, I write a lot of CGI and I want to wrap everything in a
try .. except.
try:
main()
except Exception, err:
print "Terrible blunder: ",str(err)
so that the err can be one of my exceptions, or can be one that came
with Python. (And, that I can see, err.args can be either the relevant
string or a tuple containing the relevant string and the documentation
is silent on whether in the built-in exceptions if err.args is a tuple
then the string is guaranteed to be first in the tuple.)
> (2) convert the file name to ASCII before you store it; or
I need the non-ascii information, though, which is why I included it
in the error message.
> (3) add a __str__ method to your exception that is Unicode aware.
I have two difficulties with this: (1) as above I often raise Python's
built-in exceptions and for those __str__() is what it is, and (2)
this goes against the meaning of __str__() that I find in the
documentation in ref/customization.html which says that the return
value must be a string object. Obviously no one will come to my house
and slap me if I violate that, but I'll venture that it would be odd
if the best practice were to be to do the opposite of the
documentation.

This is illuminating. How do you know that for exceptions __init__()
should take one non-self argument? I missed finding this information.

Thank you for the suggestion. Remember please that I am asking for a safe way to pull the unicode object from the exception object (derived from a Python built-in), so I can't store it as unicode first and then convert to regular string when I need to print it out-- my exact question is how to get the unicode.

Re: Diff between opening files in 'r' and 'r+' mode
It was a little hard to follow your logic of your sample code (writing,
reading and writing again), but
(1)The difference between r and r+.
- 'r+' opens the file for both reading and writing.
- 'r' should be used when the file will only be read.
I am not sure on how you want to store the contents of the file, but I have
provided an example below. You could do something like this:
--
fileContent = open(fname, 'r')
a = fileContent.readlines(); fileContent.close()
print a
--
(2) If you are just going to read the file, then yes I would use just the
'r' argument.

In Python 2.5 you can use the .partition() method which always returns
a three item tuple:
>>> text = '''\

... bcsn; 101; 1456

... print (bcsn, num1, num2)
...
('bcsn', ' 100', ' 1223')
('bcsn', ' 101', ' 1456')
('bcsn', ' 103', '')
('bcsn', ' 110', ' 4567')
>>> help(str.partition)
Help on method_descriptor:

Thanks for your answers Martin and Peter, I figured out why python.exe was asking for MSVCR80.dll. The first time I compiled the library, MS Visual C++ Express 2005 was used during the build (despite my PATH pointing to MS Visual C++ Toolkit 2003). When I removed Express 2005, I forgot to remove the build directory of my library. I've also had to remove and reinstall the C++ Toolkit, the platform SDK and the .NET Framework SDK and modify msvccompiler.py and my environment variables according to: http://www.vrplumber.com/programming/mstoolkit/index.html but finally it did work.

data design
The applications I write are made of, lets say, algorithms and data. I mean constant data, dicts, tables, etc: to keep algorithms simple, describe what is peculiar, data dependent, as data rather than "case statements". These could be called configuration data. The lazy way to do this: have modules that initialize bunches of objects, attributes holding the data: the object is somehow the row of the "table", attribute names being the column. This is the way I proceeded up to now. Data input this way are almost "configuration data", with 2 big drawbacks: - Only a python programmer can fix the file: this cant be called a configuration file. - Even for the author, these data aint easy to maintain. I feel pretty much ready to change this: - make these data true text data, easier to read and fix. - write the module that will make python objects out of these data: the extra cost should yield ease of use. 2 questions arise: - which kind of text data? - csv: ok for simple attributes, not easy for lists or complex data. - xml: the form wont be easier to read than python code, but an xml editor could be used, and a formal description of what is expected can be used. - how can I make the data-to-object transformation both easy, and able to spot errors in text data?

Under windows Ctrl-C raises KeyboardInterrupt just as it does under linux. Ctrl-break by default terminates the program (without invoking Python's usual cleanup), but you can override that behaviour by registering a different signal handler. e.g. import signal signal.signal(signal.SIGBREAK, signal.default_int_handler) will make Ctrl-break raise KeyboardInterrupt just like Ctrl-C. -- http://mail.python.org/mailman/listinfo/python-list

Use the configurations module. It was built to provide a way to parse configuration files that provide configuration data to program. It is VERY fast so the overhead to parse even thousands of lines of config data is extremely small. I use it a LOT and it is very flexible and the format of the files is easy for users/programmers to work with. -Larry Bates -- http://mail.python.org/mailman/listinfo/python-list
Synchronous shutil.copyfile()
Hi there, I have a problem. I'm using calling shutil.copyfile() followed by open(). The thing is that most of the times open() is called before the actual file is copied. I don't have this problem when doing a step-by-step debug, since I give enough time for the OS to copy the file, but at run-time, it throws an exception. Is there anyway to force a sync copy of the file (make python wait for the completion)? Thanks in advance! Hugo Ferreira -- http://mail.python.org/mailman/listinfo/python-list

Re: Synchronous shutil.copyfile()
First off, I am just learning Python, so if there is a more efficient way to do this, then I am all ears (NOTE: The code below is something that I was messing with to learn threads... So some functionality is not applicable for your needs..I just wanted to show you a demonstration) One way that you could get around this, is to use threads. You can lock your thread and when the lock has been released, you could open it and ensure your copy has succeeded. Just a thought ~~~ import thread def counter(myId, count): for i in range(count): stdoutmutex.acquire() #Copy Your File Here stdoutmutex.release() exitmutexes[myId].acquire() stdoutmutex = thread.allocate_lock() exitmutexes = [] for i in range(2): exitmutexes.append(thread.allocate_lock()) thread.start_new(counter, (i, 2)) for mutex in exitmutexes: while not mutex.locked(): #Open Your File Here print 'Exiting' On 1/30/07, Hugo Ferreira <[EMAIL PROTECTED]> wrote: Hi there, I have a problem.

The subprocess module is probably a good starting point:
http://docs.python.org/dev/lib/module-subprocess.html
It will allow you greater control over what happens with the output of a
process that you start. Specifically look at the the stdout and stderr
arguments to Popen. You can provide these with an open file descriptor or a
file object and it will dump the output into there.

Help me override append function of list object
I have created a class that inherits from the list object. I want to override the append function to allow my class to append several copies at the same time with one function call. I want to do something like: import copy class MyList(list): __init__(self): pass def append(self, object, n=1): for i in xrange(n): self.append(copy.copy(object)) Now I know this doesn't work because I overwrite append, but want the original functionality of the list object. Can someone help me? Thanks, Jeremy -- http://mail.python.org/mailman/listinfo/python-list

Re: thread and processes with python/GTK
Hi,
how do you start the python app? Goes stdout
to a terminal or a pipe?
"python script.py"
and "python script.py | cat" behave different.
Maybe "sys.stdout.flush()" helps you.
BTW, I switched from threads to idle_add for pygtk
applications.

You might try the following:
# -*- coding: iso-8859-1 -*-
import unicodedata, codecs
def transliterate(exc):
if not isinstance(exc, UnicodeEncodeError):
raise TypeError("don'ty know how to handle %r" % r)
return (unicodedata.normalize("NFD", exc.object[exc.start])[:1],
exc.start+1)
codecs.register_error("transliterate", transliterate)
print u"Frédéric Chopin".encode("ascii", "transliterate")
Running this script gives you:
$ python transliterate.py
Frederic Chopin

Re: Secret Technology of THERMATE and 911 Crime
A little intro to Uncle Al. This bastard is a spook from the criminal agencies. His job is to harass, disinform and such on the internet. He has been doing it overtime for many years. Now he was indeed doing his job in the last post. Thermate is indeed the correct terminology. When you search thermate you will find results for the demolition incendiaries accelerated by sulfur or such additives. Thermite is not the correct term since it is too wide and vague. The foundries use thermite for making alloys and that must be scrupulously free of sulfur and such additives. While thermate is the correct terminology and by its usage has now become associated with 911 research.

If all threads are blocked on mutexes, you're stuck, and at that point, it's time to abort and do tracebacks on all threads. You shouldn't have to run under a debugger to detect that. Then a timer, so that if the Global Python Lock stays locked for more than N seconds, you get an abort and a traceback. That way, if you get stuck in some C library, it gets noticed. Those would be some good basic facilities to have in thread support. In real-time work, you usually have a high-priority thread which wakes up periodically and checks that a few flags have been set indicating progress of the real time work, then clears the flags. Throughout the real time code, flags are set indicating progress for the checking thread to notice. All serious real time systems have some form of stall timer like that; there's often a stall timer in hardware. John Nagle -- http://mail.python.org/mailman/listinfo/python-list

Re: Convert raw data to XML
Actually, that's not "raw data" coming in, that's valid XML. Why do you need to indent it? Just write it to a file. If you really need to indent XML, get BeautifulSoup, read the XML in with BeautifulStoneSoup, and write it back out with "prettify()". But if the next thing to see that XML is a program, not a human, why bother?

C extension module causes bus error on Python exit
Hi all, I was referred to this list from python-help. I've written an extension module in C which contains several new types. The types can be instantiated, used, and deleted under Python 2.4.3 on OS X 10.4 without problems. However, whenever I import the module Python tries to dereference a NULL pointer and crashes *at exit*, whether or not I've instantiated any of the types. I've searched for memory leaks with gc.get_objects and Mac OS's MallocDebug utility, but haven't found any evidence. Has anyone run into a problem like this? Any help is greatly appreciated.

If you only have a couple of characters to deal with then use
replace(). Otherwise use string.translate() :
>>> import string
>>> x = 'abcd,words.words'
>>> transform = string.maketrans(',.','..')
>>> x = string.translate(x, transform)

That would be incredibly useful. Although doesn't this spark up the debate on threads killing threads? From what I understand, this is frowned upon (and was removed from java because it was dangerous). Although I think that if there was a master or control thread that watched the state of the system and could intervene, that would be powerful. One way to do this could be to use processes, and each process could catch a kill signal if it appears to be stalled, although I am absolutely sure there is more to it than that. I don't think this could be done at all with python threads though, but as a fan of python threads and their ease of use, it would be a nice and powerful feature to have. -carl -- Carl J.

DCOP memory leak?
Hello,
I'm writing a python script for Amarok, I communicate with Amarok
using DCOP.
Now, I have to call DCOP very often and I noticed that every time I
make a DCOP call my program keeps growing in memory size.
To make sure it was DCOP i wrote the small program below:
from dcopext import DCOPClient, DCOPApp
while 0==0:
dcop=DCOPClient()
dcop.attach()
AmarokDcopRes = DCOPApp ("amarok", dcop)
ok, Ms = AmarokDcopRes.player.trackCurrentTimeMs()
print Ms
If you run this script and monitor it's memory use you'll see that it
keeps growing.
Does anyone know how I can solve this problem?
Kind regards,
Tim

PythonCard
I'm having some trouble starting PythonCard on my PC. I've downloaded and ran python-2.5.msi to install Python on my machine. And PythonCard-0.8.2.win32.exe to install PythonCard. When I try to run the program I get the following error: == C:\Python25\Lib\site-packages\PythonCard\tools \codeEditor>codeEditor.py Traceback (most recent call last): File "C:\Python25\Lib\site-packages\PythonCard\tools\codeEditor \codeEditor.py", line 13, in from PythonCard import about, configuration, dialog, log, menu, model, resource, util File "C:\Python25\lib\site-packages\PythonCard\about.py", line 8, in import wx ImportError: No module named wx == Does anyone know what the problem might be?

It's probably silly, but what's about 'del dcop' as the last line of
your loop ?

Conditional expressions - PEP 308
It would be helpful if the rules of the game were spelled out more clearly. The conditional expression is defined as X if C else Y. We don't know the precedence of the "if" operator. From the little test below, it seem to have a lower precedence than "or". Thus, it is desirable for the user to put the conditional expression in parentheses. Colin W. # condExpr.py # PEP 308 defines a conditional expression as X if C else Y # but we don't know exactly what X is supposed to be. # It doesn't seem to be spelled out in the syntax. def main(): names= ['abc', 'def', '_ghi', 'jkl', '_mno', 'pqrs'] res= '' for w in names: res= res + w if w[0] != '_' else '' z= 1 print 'res1:', res res= '' for w in names: res= res + (w if w[0] != '_' else '') z= 1 print 'res2:', res if __name__ == '__main__': main() Result: [Dbg]>>> res1: pqrs res2: abcdefjklpqrs -- http://mail.python.org/mailman/listinfo/python-list

I'm using a text widget to hold a set of plots, one plot per line,
such that the scrolling capability of the text widget can be taken
advantage of to display only a subset of the plots at any given time.
In the analyses my program automates, there are at least several plots
are typically loaded into the text widget. This works out splendidly,
but the width of the plots has thus far been a static thing. Now, I'll
be able to adjust the plots widths so that when the owner window is
resized, the width of each plot in the text widget is adjusted and the
plot continues to occupy the entire text widget but no more, making
for a much more professional looking product.
I didn't mean to imply that create_window widgets should automatically
resize with the toplevel... I just couldn't find any way to force it.
Muchas gracias.
