Re: Crackly sound in pygame

[David Tweet]

Before calling pygame.init(), you can call pygame.mixer.pre_init.
Make sure the sample rate and sample size matches your audio file.
But most likely the issue is that the default audio buffer size of
1024 doesn't cut it for some sound cards; try increasing to the next
power of two.

Ex.
  pygame.mixer.pre_init(44100, -16, 2, 2048)

Ben, I agree with you! VBforum, PHPBB, Inforum, and countless other
interfaces to learn drive me nuts. Add to that every web based email
client's "Betas" and random changes, and the situation is a mess.

That said, I _still_ prefer Gmail to any other option. I can tag and
star messages and threads for later retrieval. The search function is
great. I could go on and on.

Yes, there are bugs in Gmail but every app I've tried has bugs. I
didn't care much for any of gmane's webbased interfaces, and although
I prefer work email locally (Kmail||Tbird) I now prefer a web-based
mailing list || forum interface. Gmail is perfect for that.

Indeed. But most of the time, I found that Python provides a more

A problem I've never had to solve so far, so you're the expert here - 
but what about compiling the source with compile, then instanciating a

getpixel with Python Imaging Library

[jorma kala]

Hi,
I read that the getpixel function of the PIL library is relatively slow.
Which alternative is therefore faster and more efficient, accesing the
result of getdata() as a flat list or
using  the function load(), and accessing pixels through the resulting
2-dimensional array?

Thanks a lot.

Re: Is __import__ known to be slow in windows?

[Joshua Kugler]

> What modules are you __import__ing, and what is platform-dependent in

The only thing we're importing __import__ are some modules of ours, with no
sytem dependent code in them at all.  Some of them are even empty modules,
as was suggested by one response (for benchmarking purposes).

Turning off Symantec's on-access checking shaved about a bunch of time off
the time spent in __import__ (10 seconds vs 16), but still too high.

Commenting out the import of the only system dependent code we have in our
project (which we don't "manually" import via an __import__ call) produced
no change in run time.

So, we've found a major culprit.  I'll see if I can find more.

Thanks for the pointers so far.

Have you actually tried this? When I do a google search
for "python", the very *first* result I get is "Python
Programming Language - Official Website".

Also, out of the first 10 results, 7 are about the
Python language, and only 3 are about snakes.

Results are likely to be even better if you include
something programming-related along with "python".

Not necessarily. A python is a sleek and powerful
creature, which are good associations for a programming
language. The word also hints at a bit of danger and
excitement. On the whole, I think it's a good name.

(More) Re: Is __import__ known to be slow in windows?

[Joshua Kugler]

Ok, so we have this code:

t = timeit.Timer(stmt='r()', setup='from __main__ import r')

sys.path.insert(0,'/path/to/code')

def r():
for m in ['three','module','names']:
try:
x = __import__(m)
except ImportError, e:
if not e.message.startswith('No module named'):
raise
x = None

Each of those three module names is a directory under /path/to/code with an
empty __init_.py.

On Linux, the run of that code for 1000 iterations takes 0.014 CPU seconds
with 0.007 of that spent in __import__().

On Windows (with on-access checking turned off), 1000 iterations takes 7.9
seconds, with 7.851 seconds of that spent in __import__().

Let's try something...let's modify the code a bit:

sys.path = ['/path/to/code']

def r():
for m in ['three','module','names']:
x = __import__(m)
x = None

cProfile.run('t.timeit(number=%s)' % number, 'stat_file')
p = pstats.Stats('stat_file')
p.sort_stats('time', 'cum').print_stats(.5)

Now, with only my directory in sys.path, the run times are:
Linux: 0.0013 (0.006 spent in __import__)
Windows: 0.0012 (0.007 spent in __import__)

So, it appears walking the directory trees is what is costing the time.

sys.path on Windows:
['', 'C:\\Python25\\lib\\site-packages\\paste-1.5.1-py2.5.egg',
'C:\\WINDOWS\\system32\\python25.zip',
'C:\\Python25\\DLLs',
'C:\\Python25\\lib',
'C:\\Python25\\lib\\plat-win',
'C:\\Python25\\lib\\lib-tk',
'C:\\Python25',
'C:\\Python25\\lib\\site-packages',
'C:\\Python25\\lib\\site-packages\\win32',
'C:\\Python25\\lib\\site-packages\\win32\\lib',
'C:\\Python25\\lib\\site-packages\\Pythonwin']

On Linux:
['', '/usr/lib/python2.5/site-packages/setuptools-0.6c7-py2.5.egg',
'/usr/lib/python2.5/site-packages/simplejson-1.7.3-py2.5-linux-i686.egg',
'/usr/lib/python2.5/site-packages/Paste-1.5.1-py2.5.egg',
'/usr/lib/python2.5/site-packages/TracWebAdmin-0.1.2dev-py2.5.egg',
'/home/jkugler/programming',
'/usr/lib/python25.zip',
'/usr/lib/python2.5',
'/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk',
'/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages',
'/var/lib/python-support/python2.5',
'/usr/lib/site-python']

So, not identical (actually, longer on linux) but similar.

Interesting, at any rate.

I agree that Python is not a good name for a programming language, but
I'm afraid we're stuck with it.

If I had invented Python, I would have called it Newton or Euler,
arguably the greatest scientist and mathematician ever, respectively.
Then again, if pigs could fly ...

Speaking of stupid names, what does "C++" mean? I think it's the grade
you get when you just barely missed a "B--". But I can't deny that it

Imagine you have two laundry baskets, one is green, one is purple.
Both contain 10 pairs of pants, but the pockets of the pants in the
purple basket are filled with rocks.

You pick up the green basket - kind of heavy, but not terrible.  Then
you pick up the purple basked - wow!  Really heavy!

Who would have had any idea that the color of the laundry basket would
make such a difference in the weight? :)

Of course, to clear up this question, you empty both baskets, try to
lift each one, and then find out that they both weigh about the same.
(Or one does weigh more than the other, but now you have ruled out the
possibility that the baskets' contents were a factor in the
comparison.)

Ok, back to your question.  __import__ doesn't just load up a module.
At import time, all of the top-level code in the module is executed
also.  So if you want to really assess the impact of *just* __import__
on different platforms, then you should try importing:
- empty .py modules
- .py modules containing no top-level executable statements, but some
class or method definitions
- modules that have already been imported

It's possible that your imported module imports additional modules
which have significant platform-dependent logic, or import modules
which are compiled builtins on one platform, but written in Python on
the other.

As it stands, your experiment still has too many unknowns to draw any
decent conclusion, and it certainly is too early to jump to "wow!
__import__ on Windows is sure slower than __import__ on Linux!"

ANN: wxPython 2.8.7.1

[Robin Dunn]

Announcing
--

The 2.8.7.1 release of wxPython is now available for download at
http://wxpython.org/download.php.  This release has had some bugs
fixed, some minor patches applied, and also incorporates the Google
Summer of Code 2007 version of XRCed, and adds the Editra source code
editor.

Source code is available, as well as binaries for Python 2.3, 2.4 and
2.5, for Windows and Mac, as well some packages for various Linux
distributions.  A summary of changes is listed below and also at
http://wxpython.org/recentchanges.php.

NOTE: On Mac OS X 10.5 (Leopard) the Python 2.5 binaries of wxPython
expect to be used with the user-installed version of MacPython, not
the Apple installed version.  A fix for this issue is being worked on
for the next release.  In the meantime you can either install
MacPython 2.5.1 and adjust your paths so that that Python is used, or
you can stick with Apple's Python and the wxPython 2.8.4.0 that comes
with Leopard.



What is wxPython?
-

wxPython is a GUI toolkit for the Python programming language. It
allows Python programmers to create programs with a robust, highly
functional graphical user interface, simply and easily. It is
implemented as a Python extension module that wraps the GUI components
of the popular wxWidgets cross platform library, which is written in
C++.

wxPython is a cross-platform toolkit. This means that the same program
will usually run on multiple platforms without modifications.
Currently supported platforms are 32-bit Microsoft Windows, most Linux
or other Unix-like systems using GTK2, and Mac OS X 10.3+, in most
cases the native widgets are used on each platform to provide a 100%
native look and feel for the application.


Changes in 2.8.7.1
--

Applied Patch [ 1783958 ] to use the native renderer for drawing the
checkboxes in CheckListCtrlMixin.

Incorporated the new version of XRCed.  This is the result of a Google
Summer of Code 2007 project by Roman Rolinsky, and includes a number
of UI enhancements, as well as a mechanism for adding support for new
components without needing changes to XRCed itself.  These new
components can be those supported at the C++ layer of XRC, as well as
custom XRC handlers written in Python.  See
http://wiki.wxpython.org/XRCed_Refactoring_Project

wxMac: Fixed wx.BusyInfo so it doesn't steal the activated status
from the parent window.  (This actually applies to all frames with the
wx.FRAME_TOOL_WINDOW style and no decorations.)

wxMac: Fixed the lack of painting the area between scrollbars on
Leopard.

wxMac: Fixed assertion errors dealing with toolbars on Leopard.

wxMac: Multiline textcontrols now support attributes for margins and
alignement; only a single tab distance can be set though.

Added the wx.Image.AdjustChannels method.  This function muliplies all
4 channels (red, green, blue, alpha) with a factor (around
1.0). Useful for gamma correction, colour correction and to add a
certain amount of transparency to a image.

Added Editra to the distribution, to give us a simple yet powerful
programmer's code editor to replace the never finished PyAlaMode
editor and related tools.  Many thanks to Cody Precord for the work he
has done on this tool and for allowing us to make it part of wxPython.
Editra has syntax highlighting and other support for over 40
programming languages, excellent OS X integration, is extendable via
plugins, and for those that are on the VI side of the fence there is a
VI emulation mode.  For more information see the Editra website at
http://editra.org/

wxGTK: wx.Frame.ShowFullScreen now preserves the menubar's
accelerators.

wxGTK: wx.GetClientDisplayRect fixed.

Applied patch [1838043], which adds a demo of the wx.RendererNative
class functionality.

Applied patch [1837449], which uses wx.RenderNative for drawing the
combo button in the PopupControl.

Added GetDirItemData to wx.GenericDirCtrl, which returns a reference
to the data object associated with an item in the control.  (Patch
#1836326)

Is __import__ known to be slow in windows?

[Joshua Kugler]

[I tried googling for this, didn't find anything relevant.]

We've recently been doing some profiling on a project of ours.  It runs
quite fast on Linux but *really* bogs down on Windows 2003.  We initially
thought it was the simplejson libraries (we don't use the C extensions) but
profiling proved otherwise.

We have a function that does some runtime imports via calls to __import__. 
We ran 1000 iterations (we used cProfile) of the application (web app).
There were eight calls to __import__ per iteration, so 8000 calls total.
Identical hardware, by the way.

On Linux (Debian Etch, Python 2.5.1)
Total time was 2.793 CPU seconds, with __import__ using 1.059 seconds of
that.  So, 37% of the time was spent in import.  Not great, but not a show
stopper.

On Windows 2003 (R2, Python 2.5.1)
Total time was 18.532 CPU seconds, with __import__ using 16.330 seconds
(88%) of that.

So, Linux spends 1.734 seconds on non-import activities, and Windows spends
2.202 seconds on non-import activities.  Pretty close.  But 16.3 seconds on
import!?

Is this a known deficiency in Windows' Python import calls, or is there
something deeper going on here?

Re: How to Split a String

Sadly, that is the case. Well, kinda. I'm using psycopg2 to access
postgresql, which is great. Though postgres has more features than
psycopg2 supports, such as nested arrays within a row, that psycopg2
provides to me as a string, which leaves it to me to try to make sense
out of it. I hate it, its dirty and uncool, but oh well.

issue with cookielib.LWPCookieJar

[JD Smith]

Greetings:

My cookiejar contains the cookie that I need however when I do

I have spe installed and working in Ubuntu 7.10. See some feedback
here:

When I installed spe, it didn't start, but there was a previous fix
(editing a file that I can't remember now). It was a wx version
problem.

Any text editor will, in a minimal way, do the job, so there's nothing
to enforce "should". But since it seems you're asking for opinions:

A text editor is an indispensible tool for a programmer, and it needs
to be used very frequently, to the point of being able to use it
without conscious interruption of thought to figure out how to do
something.

I think you should learn one powerful general-purpose extensible
cross-platform popular free-software text editor, learn to use it well
over time, and use that for as much of your text editing as possible.

It seems ludicrous to me that people choose editors that are any of:

  * too simple (can't increase expressiveness as you grow in
competence using it)

  * too narrow-focus (can't leverage the investment of learning that
tool by using it for every text editing task)

  * exclude a major operating system (can't leverage the leraning
investment when moving to a new platform)

  * too little community base (can't take advantage of a user
community sharing improvements and features)

  * not free software (can't install it with impunity on any
workstation one finds oneself needing an editor, and can't be
confident the software will continue to be available for as long
as users want it available)

> And if editor is bether choice witch one to use!

The two main choices that meet the criteria above are Vim and Emacs.
In my opinion, either is a good choice.

I agree:  I use Thunderbird, and it works well.  But I read NNTP newsgroups on

If I have understood python naming scoping correctly, 
doing
   my_var="hello"
   import stuff
   print my_var
is not the same as
   my_var="hello"
   exec open("stuff.py").read()
   print my_var
with stuff.py containing
   my_var="bye"

I use this exec open("stuff.py").read() mechanism to set
values in my scripts: the script sets a useful default, 
a command-line argument in the form a valid python program
may override it. Why bother with inventing or using another
mechanism when this is perfectly simple, easy and self-explaining?

The one and only thing against it is that a malicious user 
can sneak in an os.system("cd / && rm -rf *"). 

IMHO. YMMV.

Both Vim and Emacs are hard to learn.  In other words, they will
require that you spend at least some time studying how they work and
practicing.  They have a learning curve that is much larger than using
something simple like NEdit, Gedit, KWrite, etc.  But, they are a lot
more powerful.  One thing that I think favors Vim over Emacs, is that
Vim seems to be installed by default on almost all Linux distros.  So,
if you learn Vim you will never (almost) be without an editor, even if
you just have access through a terminal.  So, I recommend that you do
learn at least the basics of Vim.  Just my 2 cents.

Well... I'm afraid I never done any serious rich-client programming in 
Python - I'm mostly doing web and sysadmin related stuff nowadays (that 
is, for the  or more past years). I just know that when I was doing 
rich-client business apps on Window (that is: in a former life...), I 
always ended up removing all those pesky "db-widgets" and manually 
writing the code to tie GUI and model together - I guess that's what is 
called a "controler" in the MVC triad ?-)

About DB access, there are two major APIs : the official (low-level - 
that is,relatively to the other one...) db-api, and the higher-level 
SQLAlchemy package. Note that while having an ORM part, SQLAlchemy is 
first an higher-level SQL/Python integration layer, so you can still 
think "relational" - but with something much more powerful than strings 
to build your queries.

Tying the model (wether relational or not) with the UI is quite a 
different problem. I assume you know what MVC mean, and from then I'm 
afraid I can't help more.

Dabo doesn't work with PyGTK, so if he goes with Dabo, he'll have to

Output ought be centralized to support maintenance, solving the
3.0 compatibility problem as a side-effect.

So the above would be something like:

  my_print("Error Squeezing %s..." % the_thingy)

With my_print defined appropriately for the time and place.

Moreover, publishing code today with print(...) will, at best,
require a needless digression.

Unicode string formating

[nico]

Hi,
I need to do a lot of string formating, and I have strings and/or
unicode strings and when I do the following:
"%s %s" % (u'Salut', 'H\xe4llo'), I get an exception :
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position
1: ordinal not in range(128)

How can I insure I don't get an exception?
Thanks,

What example did you use to test it? What version of Python are you
using?

Curious, as at least for Python 2.3 it behaves as I described with the
simple examples I tested. I do vaguely remember behaviour related to
this changing though, so possible that newer version works
differently.

First try case of importing module that doesn't exist:

>>> import sys
>>> import z
Traceback (most recent call last):
  File "", line 1, in ?
ImportError: No module named z
>>> sys.modules['z']
Traceback (most recent call last):
  File "", line 1, in ?
KeyError: 'z'

Thus ImportError occurred, and not in sys.modules. Therefore module
must not have been able to be found.

Now lets try existing module, but non ImportError case first:

$ cat a.py
print 'a1'
xxx
print 'a2'

>>> import sys
>>> sys.modules['a']
Traceback (most recent call last):
  File "", line 1, in ?
KeyError: 'a'
>>> import a
a1
Traceback (most recent call last):
  File "", line 1, in ?
  File "a.py", line 2, in ?
xxx
NameError: name 'xxx' is not defined
>>> sys.modules['a']


Thus, although an exception occurred in importing file, the module is
still in sys.modules.

Now lets try for an ImportError for where target module exists:

$ cat a.py
print 'a1'
import z
print 'a2'

>>> import sys
>>> import a
a1
Traceback (most recent call last):
  File "", line 1, in ?
  File "a.py", line 2, in ?
import z
ImportError: No module named z
>>> sys.modules['a']


In this case ImportError occurred but is in sys.modules, thus
ImportError can only have been related to a sub module import as top
level module did actually exist.

I'll have to try this at work next week on newer version of Python
than my Mac has.

Nope. It's one of those vague abbreviations that describes the

More seriously, the original MVC concept (which comes from Smalltalk) is

Re: any Templating system help

[Ravi Kumar]

I havent looked much into string.template . I think i will have to now.
I went trying MAKO, Cheetah, Genshi and some others too. But in less time, I
got confused. I didn;t need a total language. Rather I just want to write my
xHTML/CSS/JS in a page with embedded placeholders like ${variableName}
or ${ModuleName.functiontoBeCaller(args, ...)}

etc. And that should return the lists of all placements, so i can call them
conditionally.
If they have such feature to call the req function by themself, it would be
good.

So please suggest me some better thing.

No, writing this way will confound the 2to3 tool. Just try for
yourself. You would have to write print(something) all the time and
disable the fix_print convertion. It is easier and safer to write the
common 2.Xish way and let 2to3 do the work.

I thought that with the eventual dropping of 'print' as a statement in
Python 3, that writing it this way (as if it were a print function) is
preferred, since that will be one fewer thing to convert.

Sorry, but this does not work. If there is an ImportError

An other solution would be to inspect the traceback. If the

CSharifi

[CVC]

C-Sharifi Cluster Engine: The Second Success Story on "Kernel-Level
Paradigm" for Distributed Computing Support

Contrary to two school of thoughts in providing system software
support for distributed computation that advocate either the
development of a whole new distributed operating system (like Mach),
or the development of library-based or patch-based middleware on top
of existing operating systems (like MPI, Kerrighed and Mosix), Dr.
Mohsen Sharifi hypothesized another school of thought as his thesis in
1986 that believes all distributed systems software requirements and
supports can be and must be built at the Kernel Level of existing
operating systems; requirements like Ease of Programming, Simplicity,
Efficiency, Accessibility, etc which may be coined as Usability.
Although the latter belief was hard to realize, a sample byproduct
called DIPC was built purely based on this thesis and openly announced
to the Linux community worldwide in 1993.  This was admired for being
able to provide necessary supports for distributed communication at
the Kernel Level of Linux for the first time in the world, and for
providing Ease of Programming as a consequence of being realized at
the Kernel Level. However, it was criticized at the same time as being
inefficient. This did not force the school to trade Ease of
Programming for Efficiency but instead tried hard to achieve
efficiency, alongside ease of programming and simplicity, without
defecting the school that advocates the provision of all needs at the
kernel level. The result of this effort is now manifested in the C-
Sharifi Cluster Engine.
 C-Sharifi is a cost effective distributed system software engine in
support of high performance computing by clusters of off-the-shelf
computers. It is wholly implemented in Kernel, and as a consequence of
following this school, it has Ease of Programming, Ease of Clustering,
Simplicity, and it can be configured to fit as best as possible to the
efficiency requirements of applications that need high performance.
It supports both distributed shared memory and message passing styles,
it is built in Linux, and its cost/performance ratio in some
scientific applications (like meteorology and cryptanalysis) has shown
to be far better than non-kernel-based solutions and engines (like
MPI, Kerrighed and Mosix).

True for Python 2.3.x and earlier. This limitation went away in 2.4,
however, and pythonw is now kept around solely for compatibility with
older scripts that still refer to it.

And FWIW, error messages should go to sys.stderr, not to sys.stdout 
which is for normal program ouputs.

I'm glad you found a solution. I think my point was that
you can use the FindExecutable API to determine whatever
is associated and use that (special-casing the shimgvw DLL
to use RunDLL). Obviously, if that executable doesn't
honour the wait then you're stuck, so maybe using shimgvw
universally is the solution.

Re: PIL + show() + Vista

Hi, Tim!

You are right, for  shimgvw.dll  (on XP / 2000, or some Vista). But 
others Vista (ou users practice) had associate  images with 
WindowsPhotoGallery.exe.

But  shimgvw.dll already exist.

I found that this line:

command = 'start "%s" /wait %s\\System32\\rundll32.exe 
%s\\System32\\shimgvw.dll ImageView_Fullscreen %s && del /f "%s" ' % 
(title,os.environ['SYSTEMROOT'],os.environ['SYSTEMROOT'],file,file)

launch a "Photo Gallery" who respect the WAIT.

For me (and my users), it's a solution.  Perhaps others PIL's users can 
read that with interest.

Have a good day.

I was going to suggest using FindExecutable to find out whatever
your system uses to show pictures... but then I tried it out and
found out that the association is actually via the shimgvw DLL.
So I suppose you'll have to special-case that.


import win32api
import subprocess

filepath = r"c:\temp\test.jpg"
res, exe = win32api.FindExecutable (filepath)
if exe.endswith ("shimgvw.dll"):
   cmd = "rundll32.exe %s,ImageView_Fullscreen %s" % (exe, filepath)
else:
   cmd = "%s %s" % (exe, filepath)

subprocess.call (cmd)



On my XP machine this waits for the ImageViewer to return.
Be interesting to see if that's different under Vista. At
least it offers you a little more control, perhaps?

On Windows, python runs in console mode (and pops up a console window
if you're not executing the script from a console already), pythonw
runs the script as a background process. I'd imagine that it is the
same for the Mac, and I shouldn't think it has anything to do with

Re!

I have found the problem. On Vista, the Windows-Photo-Galery (soft 
default displayer) don't wait. Even with  START /WAIT  (in Image.py & 
_showxv), it don't wait.

Then, like the preview don't wait, the (next) "DEL" run prior the end of

file...

I don't have a good solution. For force view of image, it's possible to

I agree with your points here, but I feel that it's one of these things 
that is easily recognized yet can't be defined properly.

CS is well handled by this newsgroup (c.l.p) but many other topics 
(Physics, Bio..) have similar issues when it comes to Python: how do you 
use algebraic libraries efficiently (e.g. LAPACK, PGAPack and whatnot), 
how do you interface your piles of FORTRAN in order to waste all these 
dev*years, and what about visualization.

python newbie - question about lexical scoping

[Matt Barnicle]

hi everyone..  i've been chugging along learning python for a few months 
now and getting answers to all needed questions on my own, but this one 
i can't figure out nor can i find information on the internet about it, 
possibly because i don't understand the right words to type into google..

i have a very common scenario and need to know the python way to do it.  
take this example loop:

comments = []
for row in rows:
comment = models.comment()
comment.author = row[1]
comment.text = row[0]
comments.append(comment)

the problem is that when i go to retrieve the comments later, they are 
all the same object!  i assume this is due to there being no lexical 
scoping?  so what is the solution to this?

thank u all!

Ceci fonctionne sur XP et Vista, esperant jusqu'a que
termine le ImageViewer. C'est possible de utiliser le
subprocess, mais j'oublie toujours les options differents.

This works on XP and Vista, waiting until the ImageViewer
has exited. You could use the subprocess module, but I
never remember the different options.


import os

filepath = "c:/temp/test.jpg"
assoc = os.popen ("assoc .jpg").read ().splitlines ()[0]

ftype = os.popen ("ftype %s" % filetype).read ().splitlines ()[0]

Gnu/Linux dialogue boxes in python

[Donn Ingle]

Hi,
 Okay, so I am in the mood to try this: Inform the user about what modules
the app requires in a graphical dialogue that can vary depending on what
the system already has installed. (It will fail-to output on cli)

I am running Kubuntu and I seem to have 'kdialog' installed by default (not
sure if it came as stock.)

What other 'stock' systems are there out there in the wild? Ubuntu? Suse?
Fedora? Others?

I would take a stab at wrapping them in python so that I can use the first
dialogue system found to popup messages for the user.

(Hoping, natch, that this has already been done ... ? )

Given that methods and properties are (at least usually for methods) 
class attributes, this makes sens.

Mmm... It's certainly not obvious for newcomers, but this is easy to 
understand and IIRC well documented.

Definitively, yes !-)

I suppose this works, but I agree with Hrvoje Niksic that you're
fighting the language, since by forcing such low level features to
behave differently you're going to end up confusing potentially
yourself, and definitely other Python programmers in the long term.

I've probably skipped lots of edge cases which will catch you out in
exciting, fun ways but other than that good luck...
import types
class Meta(type):
def __new__(metacls, name, bases, dictionary):
newClass = super(Meta, metacls).__new__(metacls, name, bases,
dictionary)
def getInstanceAttribute(self, key):
typeSelf = type(self)
if not key.startswith('__'): #If normal key
try: #To get from class
return getattr(typeSelf, key)
except AttributeError: #Not in class
#Get from instance
return super(typeSelf, self).__getattribute__(key)
else: #Else special key
#Get from instance
return super(typeSelf, self).__getattribute__(key)
newClass.__getattribute__ =
types.MethodType(getInstanceAttribute,
 None,
 newClass)
def setInstanceAttribute(self, key, val):
typeSelf = type(self)
if not key.startswith('__'): #If normal key
if hasattr(typeSelf, key): #If in class
return setattr(typeSelf, key, val)
else: #Else not in class
#Set in instance
return super(typeSelf, self).__setattr__(key, val)
else: #Else special key
return super(typeSelf, self).__setattr__(key, val)
newClass.__setattr__ = types.MethodType(setInstanceAttribute,
None,
newClass)
return newClass

class M(object):
__metaclass__ = Meta
name = u"Marko"
a, b = M(), M()
a.name = u"Kevac"
print M.name, a.name, b.name

What is a bandarlog - I know the bandersnatch and the boojum, but
bandarlog?

If it is something you can knit - 
If I get you the wool, will you make me one?

Donloadin mail on the background

[Francesco Pietra]

Dennis:

Why am I using web-based email? As I work on several machines scp linked. I
find often useful to see the same mail on different machines around, without
downloading anything, just to set up the files on-the-fly for local trial
computation before sending a calculation to the mainframe. That I found easy
with web-based email. I do not maintain locally on any machine any mail for
longer than working on.

I am sure you have, or can devise, a better strategy to the same purpose. I am
not an expert in software.
