TypeCheck vs IsInstance in C API
I'm examining the C API, and I have a question. http://docs.python.org/api/object.html There are two functions that appear to do nearly same thing, and I just want to be certain I'm not missing something. First is PyObject_IsInstance: int PyObject_IsInstance(PyObject *inst, PyObject *cls); Returns 1 if inst is an instance of the class cls or a subclass of cls, or 0 if not... Second is PyObject_TypeCheck: int PyObject_TypeCheck(PyObject *o, PyTypeObject *type); Return true if the object o is of type type or a subtype of type... Now, I can see that IsInstance can take a tuple as the second argument and check the type of the first argument against every item in the tuple. I also see that TypeCheck was added in version 2.2. Why was it added? Its functionality already seems covered by IsInstance. Is it a new-style vs. old-style class thing? -Kirk McDonald -- http://mail.python.org/mailman/listinfo/python-list

You get over a page size fairly quickly, and then many systems use anonymous mappings, where a range of pages gets mapped from swap on allocation, and unmapped on deallocation. So while this can cause address space fragmentation, it doesn't cause memory fragmentation (i.e. memory that is allocated by the process but can't be used). > I don't understand why Python doesn't have a way to give a size hint > when creating a dict.

If dicts don't work well in some cases, these cases should be investigated and fixed, instead of working around the problem by loading the problem onto the developer. As you said, it *should* have linear time, with the number of insertions. If it doesn't (and it appears not to), that may be due to hash collisions, or due to the time for computing hashes not being constant.

Too Hmmm, doesn't look like that to me -- he also posted to the Italian group (correctly in that case, since it.comp.lang.python DOES welcome Python job offers in Italian), got responses offering existing free software to do multigraphs, followed up explaining he knows about those programs but (being a non-programmer with what he thinks is a good idea) still need a contract Python programmer to work on it, etc, etc. Sounds like a person with likely good intentions that's clueless about non-English posts (and apparently job offers) being unwelcome to this newgroup (and about netiquette more generally -- reading groups' charters before posting, etc). About job offers -- I got my current (dream!) job through a long chain of circumstances which DID begin with somebody posting a job offer to this group... so, I can't honestly sympathize with the distaste that some have expressed about seeing (relevant!-) job offers here (yeah, there ARE better venues, admittedly -- but some of us dinosaurs read newsgroups regularly but check out such sites only once in a while, and only when specifically LOOKING for a job, which at the time of that post that eventually got me a job, I definitely wasn't...;-).

wait() on Popen4 object from thread?
I'm having problems calling the Popen4 object wait() method
from a thread. The folloing program produces an error on some
machines (but seems to work on others)

def monitorThread():

break
watching = True
p = popen2.Popen4('mplayer -quiet -slave test.avi')
threading.Thread(target=monitorThread).start()
while watching:
time.sleep(0.1)
--8<--
Exception in thread Thread-1:
Traceback (most recent call last):

File "/usr/lib/python2.4/popen2.py", line 94, in wait
pid, sts = os.waitpid(self.pid, 0)
OSError: [Errno 10] No child processes
Is it a requirement that the Popen4 object's wait method be
called from the same thread that created it?
Why does it work on one machine:

Nope. If you look at html tags, 2.3 code returns ... whereas 2.4 code returns... That may explain why 2.3 result is not compressed and 2.4 result is compressed, but that doesn't explain why 2.4 *is* compressed.

Hello (again), dd ...
As the effbot has said, the Python md5 and sha modules are written in C.
Hints: (1) the helpfile index says "builtin module" (2) you don't find a
sha.py or md5.py in c:\Python24\Lib\
An md5/sha library will concern itself with strings (which you obtain
from a file's *contents*), just like Python's modules do. Any struggle
with Unicode characters in the *names* of files is a separate concern.
Let's all stop worrying about low-level things like getting the 8.3
filename so that you can pass it to an MS-DOS program, and let's try to
explore why you think there is a problem with your initial approach.
At the end of this posting is a very simple Python function that
calculates the hash of a file (and its length), given the name of the
file (str or unicode, doesn't matter), which hashing module to use, and
a blocksize to use when reading. There is a really flash :-) user
interface that allows you to try it with either a glob pattern "*.txt",
or (as glob doesn't grok Windows mbcs/unicode filenames) a single
utf8-encoded filename.
Please try it out. My expectation is that, with a suitable choice of
blocksize, you will not be able to find anything that is significantly
faster and won't be difficult to interface to (like the FSUM program!).
If you have any problems or more questions, please don't hesitate to ask.

How to use tk.call ?
Hi,
I am trying to port one of my Tcl/Tk apps to Python ( 2.4.2/3).
One task is to try to be able to use my wheel mouse to scroll a Tktable
object.
The tcl code looks like:
#Support the MouseWheel
bind $ui_vars(table) { $ui_vars(table) yview scroll -5
units }
bind $ui_vars(table) { $ui_vars(table) yview scroll +5
units }
bind $ui_vars(code) { $ui_vars(code) yview scroll -5
units }
bind $ui_vars(code) { $ui_vars(code) yview scroll +5
units }
$ui_vars(table) is the table and $ui_vars(code) is a text widget.
on the python side I can get scrolling in the text widget by
# Support for mouse wheel
self.command.bind("",self.command.yview_scroll(-5 ,'units'))
self.command.bind("",self.command.yview_scroll(5,'units'))
Unfortunately the python Tkinter Table widget does not support the
yview_scroll command.
I have tried the following:
self.table.bind("",self.table.tk.call(self.table._w,'yview','scroll',-5,'units')
but, alas nothing happens
I can't find how too use tk.call, can anyone give me a clue as to how
to
solve my problem?
Thanks,
Jerry

Another option I thought of: - get the Nullsoft NSIS installer - write a Python wrapper to NSIS if desired - within your app, include: - embedded py2exe - embedded/wrapped NSIS - within your app offer a menu option to 'export this program', which changes data files as needed, then invokes py2exe and NSIS to create a whole new installer exe That way, you'd have what you're after - a way to distribute your app, including its current state, as a single EXE file.

There's one in `System.Security.Cryptography`, no need to implement your

??? maxdepth determines how deep the search will look, not the order the
search occurs. Your search only find things within 3 levels of the root,
unless your directory tree goes no deeper than that (very unlikely) the
maxdepth can't be redundant.

omniorbpy: problems sending float values
hi,
I've got a problem sending floating point values to an corba server.
With other datatyes like short or string it works fine.
So having this idl file :
module Example{
interface User{
void setV( in float x );
};
interface Target{
void getV( out short x);
};
};
I just receive zero ( -2.58265845332e-05) by sending an float to
another client with the above interface.
the client :
**
import sys
from omniORB import CORBA
import _omnipy
import Example, CosNaming
orb = CORBA.ORB_init(sys.argv, CORBA.ORB_ID)
ior = sys.argv[1]
obj = orb.string_to_object(ior)
us = obj._narrow( Example.User )
if us is None:
print "blabla"
sys.exit(1)
us.setV( 5.0 )
**
the server :
**
import sys
from omniORB import CORBA, PortableServer
import CosNaming, Example, Example__POA
class User_i( Example__POA.User ):
def setV( self, x ):
print x
print type(x)
y = float(x)
print y
print type(y)
class Target_i( Example__POA.Target ):
def getV( self ):
return 5
orb = CORBA.ORB_init(sys.argv, CORBA.ORB_ID)
poa = orb.resolve_initial_references("RootPOA")
us = User_i()
tg = Target_i()
uo = us._this()
to = tg._this()
print orb.object_to_string(uo)
print
print orb.object_to_string(to)
poaManager = poa._get_the_POAManager()
poaManager.activate()
orb.run()
**
does anyone have an answer to that kind of problem?
I mean, it just like sending short values, or strings.

Re: unexpected behaviour for python regexp: caret symbol almost useless?
Thank you Paul.
Since the only thing i'm doing is extracting this fields, and have no
plans to include other stuff, a regexp is fine. However i will take
into account 'pyparsing' when i need to do more complex parsing.
As you can see in the example i send, i was trying to get info from a
glade file, in particular i was tired of doing this everytime i need to
access a widget:
some_var = xml.get_widget('some_id')
(doing this is tiresome when you have more than 10 widgets)
So i do a little module to have all widgets instanciated as attributes
of the object, for anyone interested it is on:
http://www.lugmen.org.ar/~p10n/sources/conan/utilidades/GetWidgets.py
However is still pretty unmature, since it lacks some checks.

Now moving your program somewhere else makes that a wrong config option - and possibly your program crashes even before you have the chance to _change_ that config setting. Now you need either a fresh copy - or just edit/delete the config file. The latter sounds better to me - and most probably quite a few others programmers.

that doesn't shock me :p
anyway you're talking about instalation while I'm talkig about single
standalone file.
Besides, if it was neccessary I bet MS would make that option (and it
wouldn't be a problem since installation is not done from a sinlge file
but from the CD (should be CD-RW in that case) with lots of files and
directories so they'd create just another directory on the installation

No, but for most programs I used I never bothered to check where did

That's just the thing, I'm not a professional programmer so I was

Pre-sorted data is such a common special case (in fact, the only easily describable special case) that many systems handle this specially. For example, time timsort (Python's internal sort) on pre-sorted data; you'll find it is handled faster than random data. If you are using your gut without testing, go ahead and presort.

Well, summarizing text is one of those things that generally
takes a brain-cell or two to do. Automating the process would
require doing it either smartly (some sort of
neural-net/NLP/Markov-chain technology, which is a non-trivial
task--something one might consider braving in the 3rd or 4th-year
of a university computer-science program), or doing it fairly
dumbly. As an example of a "dumb" solution, you can use regexps
to trim off the first few words and the last few words and call
that a "summary":
>>> import re
>>> r = re.compile(r'^(.{8}.*?\b)\s.*\s(\b.{8}.*?)', re.DOTALL)
>>> s = """This is the first line
... and it has a second line
... and a third line
... and the last line is the fourth line."""
>>> result = r.sub(r"\1...\2",s.strip())
>>> result
'This is the...fourth line.'
You can adjust the "{8}" portions for more or less
leader/trailing context characters.
The regexp might need a bit of tweaking for somewhat short
strings, but if they're fairly short, one might not need to
summarize them ;)

Put your program in a writable folder and save configuration right into
that folder. Then your can transfer the whole folder. Tip: sys.path[0]
always contains the path to the directory where "__main__" module is

Sure. More on this below.

Yep. I do not need POSIX *syntax* for regular expressions but POSIX
*semantics*, at least the "leftmost-longest" part (in contrast to the
"first then longest" used in Python, Perl, .NET, etc.)
> The operands of | are such that the length is not fixed and so you can't

> about those operands?
Basically, I'd like to use the (excellent) python module SPARK
of John Aycock to build an (extended) C lexer. To do so, I need
to specify the patterns that match my tokens as well as a priority
between them. SPARK then builds a big alternate list of patterns
that begins with the high priority patterns and ends with the low
priority patterns and runs a match.
The problem with to be very careful and to specify explicitely the
priorities to get the desired results: "<=" shall be higher than "<",
decimal stuff higher than integer, etc, when most of the time what
you really want is to match the longest pattern ...
Worse, the priority work-around does not work well when you
compare keywords and (other) identifiers. To match "fortune"
as a identifier, you would need to define identifier with a higher
priority than keyword and it is a problem: "for" would be then
match as a identifier when it is a keyword.
I can come up with possible work-arounds for the "id vs
keyword" issue, but nothing that really makes me happy ...
Therefore, I was studying the possible replacement of the
Python native regular expression engine with a "POSIX
semantics" regular expression engine that would give the
longest match and avoid me a lot of extra work ...
I hope it's clearer now :)
Any advice ?
Cheers

It _might_ come as a shock to you, but when you install e.g. Word on another
computer, there aren't any documents coming with it. Especially not the

You can try to write a multi-threaded application server that provides services through TCP/IP. Probably, the easiest to start with an existing framework: http://twistedmatrix.com/projects/core/ http://www.webwareforpython.org/ There are many other libraries, you can look for them in the cheeseshop. http://cheeseshop.python.org/pypi You can also develop your own protocol with SocketServer or xmlrpc: http://docs.python.org/lib/module-SocketServer.html http://docs.python.org/lib/module-xmlrpclib.html Best, Laszlo -- http://mail.python.org/mailman/listinfo/python-list

Re: itertools.count() as built-in
Oops. The messed-up version wasn't supposed to be messed-up. Two mistakes on one line. Which kinda proves my point :) I'd much rather use the count version than (1) or (2). (1) has the problem of having "incorrect" values the rest of the time in the loop and (2) is going to an extreme just to avoid an import of count. Your zipwithcount doesn't look as obvious as for n, a, b in zip(count(), A, B) but is still easier to read than for n, (a, b) in enumerate(zip(A, B)) -Janto -- http://mail.python.org/mailman/listinfo/python-list

Last Call - proposals for talks in the business and application track at EP 2006
In 2006, EuroPython will be from the 3rd to the 5th of July at CERN,
near Geneva in Switzerland.
In business & applications we want to hear about how you made your
fortune with Python. Show us YOUR interesting released Python
applications. Describe your fabulous business models with Open Source
Software. Report about your pub cashier solution in Python and how you
solved the challenges of longer opening hours. Narrate the background
stories about your next generation search engine which has just gone
live.
Explain us the technique, tell us the story, paint your business model!
Show us how YOU got affluent, opulent, pecunious, proliferative,
prosperous and wealthy - all using Python!
Do you use Python to make big business in the lumber sawing or porn
industrie? Let us know how!
Move up to
http://www.europython.org/sections/tracks_and_talks/announcements/call-for-proposals
and submit your proposal. DEADLINE is 2006-05-31 - so do not hesitate
any further!
All who still need to know how to get rich and improve their love life
using Python:
you are heartly invited to register for EuroPython 2006 via the website
http://www.europython.org
The "normal fee" is 190 for three days of seminars and a fine
conference dinner.
In addition to our great conference, you have the possibility to visit
CERN! Maybe you read about it in Angel & Demons ("Illuminati" in
German)
from Dan Brown; maybe you know that Sir Tim Berners-Lee invented the
World Wide Web there.
You will have the chance to eat in canteens with the highest
probability
anywhere in the world to stand in queue with a future or past Nobel
Prize Winner. You can learn about the technologies that will power Web
2.5 and above at the place where Web 0.1 up to Web 1.0 were developed.
CERN says about itself: "The world's largest particle physics
laboratory ... where the web was born!". As a German you are
culturally obligued to go the place where they try to find out "was
die Welt / in ihrem innersten zusammenhält". (So that I may perceive
whatever holds / The world together in its inmost folds (Faust I)) -
learn about that place at www.cern.ch
