Tim answered your actual question, but why are you doing this in the
first place? The Python standard library provides all the
functionality that dir will provide and you don't have to parse the
output...
Look into <http://www.python.org/doc/lib/os-file-dir.html>, and
specifically, os.listdir(path).

Hi,
Today I've been thinking a bit about the "python internals". Inspired
by this recipe:
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/6606 2
I found out a little problem which haven't been able to solve.
In short, is there a way to find out how a given name lookup was started?
It is not enough to know the name of the caller as given by the recipe.
a little example:
import inspect
class test(object):
def __init__(self, a_list):
self.my_list = a_list
def info(self):
for counter, item in
enumerate(inspect.getouterframes(inspect.currentframe())):
print counter, item
return self.my_list
data = property(info)
if __name__ == '__main__':
a = test([1111,2222])
def g(a_seq):
for item in a_seq:
print item, '\n'
g(a.data)
This prints
0 (<frame object at 0x00B58B08>, 'myfile.py', 10, 'info', ['
for counter, item in
enumerate(inspect.getouterframes(inspect.currentframe())):\n '], 0)
1 (<frame object at 0x00A5B000>, 'myfile.py', 38, '<module>', ['
g(a.data)\n'], 0)
1111
2222
What I would like is a reference to g itself, and not only to
'<module>' which is the caller according to f_code.co_name.
I thought of manually parsing the string ' g(a.data)\n' to extract
the name but I'm sure that it would be a rather fragile approach, and
so I decided that it was time to ask for help :-)
To 'get a feeling', I tried to disassemble the code:
code = compile('g(a.data)', 'test', 'single')
dis.dis(code)
and this is the result
0 LOAD_NAME 0 (g)
3 LOAD_NAME 1 (a)
6 LOAD_ATTR 2 (data)
9 CALL_FUNCTION 1
12 PRINT_EXPR
13 LOAD_CONST 0 (None)
16 RETURN_VALUE
So ... I'm looking for the first name loaded. Is there a reference to
it, somewhere?

Now how was this survey advertised? Who was asked to participate?
Dunno. Clearly not MacFans, given the high number of 1 scores given to
Objective C + cocoa.
Interestingly, python got the most votes (619--the next highest were 518
(Java) and 505 (Ruby)), the highest average score (8.5 out of 10,
followed by HTML/CSS with 7.6 and Javascript with 7.3), *and* the
highest percentage of 10 scores, (49.3%, with HTML/CSS second with 28.6%).

Besides all that, we are programmers not fashion models. Who cares which

trade is code, not fashion.

That's because "dir" isn't an executable file in its
own right, merely a subcommand of the command shell.
Do this:
<code>
from subprocess import *
p1 = Popen ("dir", shell=True, stdout=PIPE)
print p1.communicate ()[0]
</code>

I'm happy to announce that I have just uploaded the latest release
(v1.4.8) of pyparsing. This release has a few new features and
corresponding demonstration examples. There are also a few minor
bug-fixes, and a performance speedup in the operatorPrecedence method.
Here are the notes:
- Added new helper method nestedExpr to easily create expressions
that parse lists of data in nested parentheses, braces, brackets,
etc.
- Added withAttribute parse action helper, to simplify creating
filtering parse actions to attach to expressions returned by
makeHTMLTags and makeXMLTags. Use withAttribute to qualify a
starting tag with one or more required attribute values, to avoid
false matches on common tags such as <TD> or <DIV>.
- Added new examples nested.py and withAttribute.py to demonstrate
the new features.
- Added performance speedup to grammars using operatorPrecedence,
instigated by Stefan Reichör - thanks for the feedback, Stefan!
- Fixed bug/typo when deleting an element from a ParseResults by
using the element's results name.
- Fixed whitespace-skipping bug in wrapper classes (such as Group,
Suppress, Combine, etc.) and when using setDebug(), reported by
new pyparsing user dazzawazza on SourceForge, nice job!
- Added restriction to prevent defining Word or CharsNotIn expressions
with minimum length of 0 (should use Optional if this is desired),
and enhanced docstrings to reflect this limitation. Issue was
raised by Joey Tallieu, who submitted a patch with a slightly
different solution. Thanks for taking the initiative, Joey, and
please keep submitting your ideas!
- Fixed bug in makeHTMLTags that did not detect HTML tag attributes
with no '= value' portion (such as "<td nowrap>"), reported by
hamidh on the pyparsing wiki - thanks!
- Fixed minor bug in makeHTMLTags and makeXMLTags, which did not
accept whitespace in closing tags.
Download pyparsing 1.4.8 at http://sourceforge.net/projects/pyparsing/.
The pyparsing Wiki is at http://pyparsing.wikispaces.com
-- Paul
========================================
Pyparsing is a pure-Python class library for quickly developing
recursive-descent parsers. Parser grammars are assembled directly in
the calling Python code, using classes such as Literal, Word,
OneOrMore, Optional, etc., combined with operators '+', '|', and '^'
for And, MatchFirst, and Or. No separate code-generation or external
files are required. Pyparsing can be used in many cases in place of
regular expressions, with shorter learning curve and greater
readability and maintainability. Pyparsing comes with a number of
parsing examples, including:
- "Hello, World!" (English, Korean, Greek, and Spanish(new))
- chemical formulas
- configuration file parser
- web page URL extractor
- 5-function arithmetic expression parser
- subset of CORBA IDL
- chess portable game notation
- simple SQL parser
- Mozilla calendar file parser
- EBNF parser/compiler
- Python value string parser (lists, dicts, tuples, with nesting)
(safe alternative to eval)
- HTML tag stripper
- S-expression parser
- macro substitution preprocessor

Thanks Gabriel!
I get it now. With your help I was able to focus on the real problem.
Here is the correctly working example for the record:
import gc
class Test(object):
def __init__(self):
pass
gc.collect()
original_objects_id = [id(x) for x in gc.get_objects()]
#create object a
a = Test()
gc.collect()
new_objects = [x for x in gc.get_objects()
if id(x) not in original_objects_id]
print "-" * 40
print "Added object:", len(new_objects)
for obj in new_objects:
print "*" * 10
print str(id(obj)) + ":" + str(obj)
print gc.get_referents(obj)
print "*" * 3
print "-" * 20
del new_objects
del obj
gc.collect()
original_objects_id = [id(x) for x in gc.get_objects()]
#remove object a
del a
gc.collect()
after_rm_objects_id = [id(x) for x in gc.get_objects()]
removed_objects_id = [idx for idx in original_objects_id
if idx not in after_rm_objects_id]
print "-" * 40
print "Removed objects:", len(removed_objects_id)
print removed_objects_id
print "-" * 20

Not exactly: an object is created and bound to the name "a". Some code is
executed... Later, the name "a" is removed; the object's reference count
is decremented, but the object itself can only be removed when the r.c.
goes to zero.
> Why in the second part of the example I do not see any object removed:
Because you still hold a reference to the object.

Hi,
I am trying to create a leftarrow of \vv{}. I thought I could just
reflect the vector, but the solution has escaped me. Could someone help
me out?
\def\traitfill@#1#2#3#4{%
$\m@th\mkern2mu\relax#4#1\mkern-1.5mu%
\cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%
\mkern-1.5mu#3$%
}
was replaced with
\def\traitfill@#1#2#3#4{%
\reflectbox{$\m@th\mkern2mu\relax#4#1\mkern-1.5mu%
\cleaders\hbox{$#4\mkern0mu#2\mkern0mu$}\hfill%
\mkern-1.5mu#3$}%
}
But the result is incorrect (the vector does not fill properly).
Thanks.

subprocess performs double quoting (necessary for paths with spaces)
automatically.
Therefor both the following lines:
cmd.append ( '-sD:\\PIC-tools\\JAL\\libs2' )
cmd.append ( '>d:\\data_actueel\\d7_test_browser\\temp.log' )
should become
cmd.append ( '-s' )
cmd.append ( ' D:\\PIC-tools\\JAL\\libs2' )
cmd.append ( '>' )
cmd.append ( 'd:\\data_actueel\\d7_test_browser\\temp.log' )
then everything works perfect, also with the convenience call "call"
and the redirection.
thank you all for the hints,
cheers,
Stef Mientki

I would need help to understand how garbage collection work and how to
"trace" objects...
In the example below an object is created and deleted.
Why in the second part of the example I do not see any object removed:
import gc
class Test(object):
def __init__(self):
pass
gc.collect()
original_objects_id = [id(x) for x in gc.get_objects()]
#create object a
a = Test()
gc.collect()
new_objects = [x for x in gc.get_objects()
if id(x) not in original_objects_id]
print "-" * 40
print "Added object:", len(new_objects)
for obj in new_objects:
print "*" * 10
print str(id(obj)) + ":" + str(obj)
print gc.get_referents(obj)
print "*" * 3
print "-" * 20
gc.collect()
original_objects_id = [id(x) for x in gc.get_objects()]
#remove object a
del a
gc.collect()
after_rm_objects_id = [id(x) for x in gc.get_objects()]
removed_objects_id = [x for x in original_objects_id
if x not in after_rm_objects_id]
print "-" * 40
print "Removed objects:", len(removed_objects_id)
print removed_objects_id
print "-" * 20
Which give:
----------------------------------------
Added object: 2
**********
400600:[[...], <__main__.Test object at 0x62bd0>]
[<__main__.Test object at 0x62bd0>, [[...], <__main__.Test object at 0x62bd0>]]
***
**********

I'm looking for a simple HTTP proxy that I can modify to fix the
"brokenness" of a website that I use often. One aspect of the
"brokenness" is that if I visit the site from two different tabs in my
browser, what I do in one tab will interfere with what happens in the
other. There are a few other minor issues I want to tweak to my liking.
I thought a simple local proxy would give me maximum flexibility when it
comes to the tweaking part.
http://www.xhaus.com/alan/python/proxies.html contains a list of
potential candidates but it's difficult to get a feel of the ease of
modification.
I'd like to hear your experience/recommendation if you have solved a
similar problem before.
Thanks.

OK. Given that my (widescreen) monitor, like most current monitors, does
not rotate into the portrait mode that would display a whole page, double
column pdf files are painful to read on a screen. Up and down, up and
down. And the color pages cannot be sensibly printed on a b/w printer,
even if I wanted to go to paper (which is what pdf was meant for), which I
do not. Mismatching electronic documents to the screens they are most
commonly read on is to me at least shortsighted. So I suggest that you
also produce a readable html version.

thanks Adam,
that indeed it works,
but googling for killProcName.py I found messages about it being slow,
and indeed it's slow,
and that same google search turned up a faster method, see below.
thanks again,

Thanks Nick,
replacing
#print out, err, rcode
with
for line in out:
print line
for line in err:
print line
points me to the problem issue, which is the "-s" option,

Version 0.3.7 of the Python config module has been released.
What Does It Do?
================
The config module allows you to implement a hierarchical configuration
scheme with support for mappings and sequences, cross-references
between one part of the configuration and another, the ability to
flexibly access real Python objects, facilities for configurations to
include and cross-reference one another, simple expression evaluation
and the ability to change, save, cascade and merge configurations. You
can easily integrate with command line options using optparse.
This module has been developed on python 2.3 but should work on
version 2.2 or greater. A test suite using unittest is included in the
distribution.
A very simple configuration file (simple.cfg):
# starts here
message: Hello, world!
#ends here
a very simple program to use it:
from config import Config
cfg = Config(file('simple.cfg'))
print cfg.message
results in:
Hello, world!
Configuration files are key-value pairs, but the values can be
containers that contain further values.
A simple example - with the example configuration file:
messages:
[
{
stream : `sys.stderr`
message: 'Welcome'
name: 'Harry'
}
{
stream : `sys.stdout`
message: 'Welkom'
name: 'Ruud'
}
{
stream : $messages[0].stream
message: 'Bienvenue'
name: Yves
}
]
a program to read the configuration would be:
from config import Config
f = file('simple.cfg')
cfg = Config(f)
for m in cfg.messages:
s = '%s, %s' % (m.message, m.name)
try:
print >> m.stream, s
except IOError, e:
print e
which, when run, would yield the console output:
Welcome, Harry
Welkom, Ruud
Bienvenue, Yves
The above example just scratches the surface. There's more information
about this module available at
http://www.red-dove.com/python_config.html
Comprehensive API documentation is available at
http://www.red-dove.com/config/index.html
As always, your feedback is most welcome (especially bug reports,
patches and suggestions for improvement). Enjoy!
Cheers
Vinay Sajip
Red Dove Consultants Ltd.
Changes since the last release posted on comp.lang.python[.announce]:
=====================================================
Added Mapping.__delitem__ (patch by John Drummond).
Mapping.__getattribute__ no longer returns "" when asked
for "__class__" - doing so causes pickle to crash
(reported by Jamila Gunawardena).
Allow negative numbers (reported by Gary Schoep; had
already been fixed but not yet released).

You are not going to like this recommendation.
Use Tkinter instead - seems to work nicely cross platform for me.

First, call is a convenience function, but in your case, it's probably
not that convenient. Use the actual Popen constructor so you can get
at the output directly. Also, ditch the output redirector and use a
pipe:
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
(out, err) = p.stdout, p.stderr
rcode = p.wait()
print out, err, rcode
Try that and see what happens. When it doesn't work, look carefully
in out and err and see if anything interesting is in there. I was
able to open notepad.exe in this way with no problems so my guess is
you're having some other problem, but avoiding the use of the
convenience function will give you stdout and stderr to look at.

Open Source Applications Foundation (OSAF) released Chandler Preview
(0.7.0.1) on September 10, 2007.
Chandler is a Personal Information Management (PIM) client application
with innovative design and ambitious plans for sharing, extensibility
and cross-platform support. Chandler is written mainly in Python.
We now have public-beta quality releases of our products; we believe
them to be full featured enough and stable enough for daily use. Check
out a full overview of features (including screenshots and screencasts).
Download Chandler Desktop, create an account on Chandler Hub. Check out
the source. Get involved in the project, help us build a really great
1.0 release.
Chandler desktop adds a central dashboard for managing tasks, notes,
events, and messages to the basic calendar functionality found in the
0.6 release. You can share calendars, task lists, messages and notes in
collections that can hold whatever you choose to put in them, regardless
of data type. The performance has improved greatly, the application has
basic search functionality, and now there’s a way to to manage and
resolve conflicts on shared data. You can collaborate on individual
items via email with the ability to edit and update messages you’ve
already received or sent. Although Chandler Preview is not meant to
replace your email application, you can configure your IMAP account so
that Chandler can see some messages from your regular mail client.
Get it from http://chandlerproject.org/

The options should have all been relative to the release date.
Options one and two might very well be the same (yes, I know, but shit
happens). Also, you're relying on people knowing the current
timeframe for 3.0.

I would imagine it's the SpamBayes score your posts are currently

There are as many different regex flavours as there are Linux distros.
Each follows the basic rules but implements them slightly differently
and adds their own 'extensions'.

The best place to pose a regex question is in the sphere of usage, i.e.
Perl regexes differ hugely in implementation from OO langs like Python
or Java, while shells like bash or zsh use regexes slightly differently,
as do shell scripting languages like awk or sed.

If you care to PM me with details of the language/context I will try to
help but I am no expert.

just to be clear...these are some variants you may find in
non-python regexps (or in python regexps if you're not using raw
strings)

....if you want to accept patterns like

The regexp at the top (Adam's original reply) would be the valid
regexp in python and matches all the tests thrown at it, assuming
it's placed in a raw string:
r = re.compile(r"@param\[(in|out)\] \w+")
If it's not a python regexp, this isn't really the list for the
question, is it? ;)
However, things to try:
- sometimes the grouping parens need to be escaped with "\"
- sometimes "\w" isn't a valid character class, so use the
long-hand variant of something like "[a-zA-Z0-9_]]
- sometimes the "+" is escaped with a "\"
- if you don't use raw strings, you'll need to escape your "\"
characters, making each instance "\\"

Comment Reflower appears to be a plugin for Visual Studio written in
C#. As far as I can tell, it has nothing to do with Python at all.
A quick look at their sourceforge page
(http://sourceforge.net/projects/commentreflower/) doesn't show any
mailing lists or discussion groups. Maybe try emailing the author
directly, or asking a C# language group about whatever the standard C#
regular expression library is.

You *are* talking about python regular expressions, right? There are a number of different dialects. Also, there could be issues with the quoting method (are you using raw strings?)
The more specific you can get, the more we can help you.
