IMDbPY 2.3 released
IMDbPY 2.3 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about both movies and people. This is mainly a bugfixes release; some bugs in mobile, sql and http data access systems were solved. Platform-independent and written in pure Python (and few C lines), it can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page. -- Davide Alberani [EMAIL PROTECTED] [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/ -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
akismet 0.1.2, cgiutils 0.3.5, pathutils 0.2.3
Hello All,
A new release and two updates.
New akismet.py 0.1.2
Python Interface to the Akismet API
Version 0.1.2 4th December 2005
http://www.voidspace.org.uk/python/modules.shtml#akismet
`Akismet http://www.akismet.com`_ is a web service for recognising
spam comments. It promises to be almost 100% effective at catching
comment spam. They say that currently 81% of all comments submitted to
them are spam.
It's designed to work with the `Wordpress Blog Tool
http://wordpress.org/`_, but it's not restricted to that - so this is
a Python interface to the `Akismet API
http://akismet.com/development/api/`_.
You'll need a `Wordpress Key http://wordpress.com`_ to use it. This
script will allow you to plug akismet into any CGI script or web
application, and there are full docs in the code. It's extremely easy
to use, because the folks at akismet have implemented a nice and
straightforward {acro;REST;REpresentational State Transfer} API.
It also comes with an `example CGI
http://www.voidspace.org.uk/cgi-bin/akismet/test_akismet.py`_.
(Although the akismet feature of an example positive doesn't seem to
be working currently - there fault not mine :-)
You can read the full (Python) docs at :
* `akismet.py Docs
http://www.voidspace.org.uk/python/akismet_python.html`_

cgiutils 0.3.5 - pathutils 0.2.3
=
pathutils 0.2.3 November 26th 2005
cgiutils 0.3.5 November 26th 2005
http://www.voidspace.org.uk/python/recipebook.shtml#utils
These two modules contain functions and constants for *'general'* use.
They are
both included as part of the `Voidspace Pythonutils Package
http://www.voidspace.org.uk/python/modules.shtml#pythonutils`_ .
(A new release of pythonutils - containing these updated modules - is
due shortly).
**Pathutils** contains various functions for working with files and
paths. This
includes (amongst other thing) :
* Easy ways to iterate over files and directories
* A function to calculate a relative path from one location to another
* Several 'convenience' file reading/writing functions
* `py2exe http://www.py2exe.org`_ directory support
* A function for pretty printing file sizes
* A simple solution to cross-platform file locking
* Import from a specific location
See the `pathutils Homepage
http://www.voidspace.org.uk/python/pathutils.html`_.
**CGI utils** has (guess what... {sm;:?:}) various functions for use
with CGI.
It contains functions to do things that every CGI has to cope with.
They are
most useful for simple scripts, where a full blown framework would be
too
cumbersome.
It includes (amongst other thing) :
* Functions for receiving form submissions
* Cross platform functions to send emails (including creating
{acro;HTML}
emails)
* A basic templating system
* A {acro;DNS;Domain Name System} blacklist lookup
* A function to generate a menu line for pages with lots of results
See the `cgiutils Homepage
http://www.voidspace.org.uk/python/cgiutils.html`_.
Download them here :
*
http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=utils.zip
(25k) (both modules)

Re: Tabs bad (Was: ANN: Dao Language v.0.9.6-beta is release!)
Steven D'Aprano enlightened us with: It seems to me that one tab per indent level is far more logical than some arbitrary number, N, of spaces, often a multiple of eight, or four, or two, per indent level, and hope that the number of spaces is a multiple of that arbitrary N. But maybe that's just me. It's me too. One tab per indent makes perfect sense. went back to tabs, got frustrated with people complaining that indentation was being mangled by various webmail and News clients This is about the only place where I use four spaces (typed as one tab, expanded by Vim): email and Usenet. The reason? I don't want my post to become too wide. If my stuff is read by someone with tab sizes larger than four, it might become too wide, so to prevent that I use spaces. For all other things (like real source code instead of a pasted snippet) I use tabs. I'm almost fired up enough about this to start the Society For The Treatment Of Tabs As First Class Characters. *wink* LOL count me in ;-) Sybren -- The problem with the world is stupidity.

Re: regexp non-greedy matching bug?
Aahz wrote:
While you're technically correct, I've been bitten too many times by
forgetting whether to use match() or search(). I've fixed that problem
by choosing to always use search() and combine with ^ as appropriate.
that's a bit suboptimal, though, at least for cases where failed matches
are rather common:
C:\timeit -s import re; p = re.compile('b') p.match('a'*100)
10 loops, best of 3: 6.14 usec per loop
C:\timeit -s import re; p = re.compile('^b') p.match('a'*100)
10 loops, best of 3: 6.25 usec per loop
C:\timeit -s import re; p = re.compile('^b') p.search('a'*100)
10 loops, best of 3: 15.4 usec per loop
(afaik, search doesn't have any heuristics for figuring out if it can skip
the search, so it'll check ^ against all available positions)
on the other hand, benchmarking RE:s always results in confusing
results:
C:\timeit -s import re; p = re.compile('b') p.search('a'*100)
10 loops, best of 3: 4.32 usec per loop

assuming that you know how you want the HTML to look (styles and headers

string concatenation is not an efficient idiom. In a loop, the common
idiom is to use a list and join it, but here I guess a triple quoted
string and simple templating trick would be better.
# output markers, if any
t = t + str
# then add trailing html to finish page
trail = //]] /script /body /html
t = t + trail
return t
This is definitevely not how I would do HTML/js in Python. There are a
lot of templating / HTML generation tools available, that allow to
cleanly separate logic from presentation.

ISTM the line above is a symptom of a bug in your mental Python source

It's a contradiction. A list can't be a const expression.
We probably can't make real progress until that is debugged ;-)
Note: assert const expression is a list should raise a mental exception ;-)
Why should const expression is a list raise a mental exception with
me? I think it should have raised a mental exception with the designer.
If there is a problem with const list expression, maybe the language
shouldn't have something that looks so much like one?
This seems to go against the pythonic spirit of explicit is
better than implicit.
Unless you accept that '[' is explicitly different from '(' ;-)
It also seems to go against the way default arguments are treated.
I suspect another bug ;-)
The question is where is the bug? You can start from the idea that
the language is how it was defined and thus by definition correct
and so any problem is user problem.
You can also notice that a specific construct is a stumbling block
with a lot a new people and wonder if that doens't say something
about the design.
Do you want
to write an accurate historical account, or are you expressing discomfort
from having had to revise your mental model of other programming languages
to fit Python? Or do you want to try to enhance Python in some way?
If there is discomfort, then that has more to do with having revised
my mental model to python in one aspect doesn't translate to
understanding other aspects of python enough.
An example?
Well there is the documentation about function calls, which states
something like the first positional argument provided will go
to the first parameter, ... and that default values will be used
for parameters not filled by arguments. Then you stumble on
the build in function range with the signature:
range([start,] stop[, step])
Why if you only provide one arguments, does it go to the second
parameter?
Why are a number of constructs for specifying/creating a value/object
limited to subscriptions? Why is it impossible to do the following:
a = ...
f(...)
a = 3:8
tree.keys('a':'b')
Why is how you can work with defaults in slices not similar with
how you work with defaults in calls. You can do:
lst[:7]
So why can't you call range as follows:
range(,7)
lst[::] is a perfect acceptable slice, so why doesn't, 'slice()' work?
Positional arguments must come before keyword arguments, but when
you somehow need to do the following:
foo(arg0, *args, kwd = value)
You suddenly find out the above is illegal and it should be written
foo(arg0, kwd = value, *args)
people are making use of that rule too much, making the total language
less pratical as a whole.
IMO this is hand waving unless you can point to specifics, and a kind of
unseemly propaganda/innuendo if you can't.
IMO the use of negative indexing is the prime example in this case.
Sure it is practical that if you want the last element of a list,
you can just use -1 as a subscript. However in a lot of cases -1,
is just as out of bounds as an index greater than the list length.
At one time I was given lower en upperlimit for a slice from a list,
Both could range from 0 to len - 1. But I really needed three slices,
I needed lst[low:up], lst[low-1,up-1] and lst[low+1,up+1].
Getting lst[low+1:up+1] wasn't a problem, The way python treated
slices gave me just what I wanted, even if low and up were to big.
But when low or up were zero, the lst[low-1,up-1] gave trouble.
If I want lst[low:up] in reverse, then the following works in general:
lst[up-1 : low-1 : -1]
Except of course when low or up is zero.
Of course I can make a subclass list that works as I want it, but IMO that
is the other way around. People should use a subclass for special cases,
like indexes that wrap around, not use a subclass to remove the special
casing, that was put in the base class.
Of course this example fits between the examples above, and some of
those probably will fit here too.
or what are we pursuing?
What I'm pursuing I think is that people would think about what
impractical effects can arise when you drop purity for practicallity.
I think this is nicely said and important. I wish it were possible
to arrive at a statement like this without wading though massive
irrelevancies ;-)
Well I hope you didn't have to wade such much this time.

It seems to me that the tabs-vs-spaces thing is really about who controls the indentation: with spaces, it's the writer, and with tabs, it's the reader.

D H wrote: How is that a problem that some editors use 8 columns for tabs and others use less? So what? A bigger problem I see is people using only 2 or 3 spaces for indenting. That makes large amounts of code much less readable. And of course it is a problem if you mix tabs and spaces at the beginning of the same line. Tabs are easier to type (one keystroke each) and lead to visually better results (greater indentation unless you like hitting 8 spaces for each indent level). Where does that misconception that 2-3 spaces for indenting makes things less readable come from? There was an article in Comm. of the ACM on research into readability back in 1984 or so, that indicated 2-4 spaces has very similar readability and 8 spaces significantly less than that. IIRC they took care of personal preferences/what one was used to in the research. So disallowing tabs which could be set to 8 spaces (positions?) does make sense to me. I switched from using 2 to using 4 spaces for Python recently, and the big pain was to deal with lines that no longer fitted in 80 columns :-( -- http://mail.python.org/mailman/listinfo/python-list

If we're going to be creating evangelical tools, I think a decent description or tutorial explaining why scoping through indentation is a better idea, rather than capitulating to the ignorance of those who won't try something different. If you repeat a piece of functionality, you factor it out into a single function. If you repeat a piece of data, you normalise it into a separate table or object. If you consistently find yourself having to enter a new scope and indent at the same time, and close scopes and unindenting at the same time, the sensible approach is to combine these concepts into one. Surely any programmer worthy of the term can see benefits to the approach when it is not just mentioned as a bizarre and arbitrary limitation of the language. -- Ben Sizer -- http://mail.python.org/mailman/listinfo/python-list

akismet 0.1.2, cgiutils 0.3.5, pathutils 0.2.3
Hello All,
A new release and two updates.
New akismet.py 0.1.2
Python Interface to the Akismet API
Version 0.1.2 4th December 2005
http://www.voidspace.org.uk/python/modules.shtml#akismet
`Akismet http://www.akismet.com`_ is a web service for recognising
spam comments. It promises to be almost 100% effective at catching
comment spam. They say that currently 81% of all comments submitted to
them are spam.
It's designed to work with the `Wordpress Blog Tool
http://wordpress.org/`_, but it's not restricted to that - so this is
a Python interface to the `Akismet API
http://akismet.com/development/api/`_.
You'll need a `Wordpress Key http://wordpress.com`_ to use it. This
script will allow you to plug akismet into any CGI script or web
application, and there are full docs in the code. It's extremely easy
to use, because the folks at akismet have implemented a nice and
straightforward {acro;REST;REpresentational State Transfer} API.
It also comes with an `example CGI
http://www.voidspace.org.uk/cgi-bin/akismet/test_akismet.py`_.
(Although the akismet feature of an example positive doesn't seem to
be working currently - there fault not mine :-)
You can read the full (Python) docs at :

=
pathutils 0.2.3 November 26th 2005
cgiutils 0.3.5 November 26th 2005
http://www.voidspace.org.uk/python/recipebook.shtml#utils
These two modules contain functions and constants for *'general'* use.
They are
both included as part of the `Voidspace Pythonutils Package
http://www.voidspace.org.uk/python/modules.shtml#pythonutils`_ .
(A new release of pythonutils - containing these updated modules - is
due shortly).
**Pathutils** contains various functions for working with files and
paths. This
includes (amongst other thing) :
* Easy ways to iterate over files and directories
* A function to calculate a relative path from one location to another
* Several 'convenience' file reading/writing functions
* `py2exe http://www.py2exe.org`_ directory support
* A function for pretty printing file sizes
* A simple solution to cross-platform file locking
* Import from a specific location
See the `pathutils Homepage
http://www.voidspace.org.uk/python/pathutils.html`_.
**CGI utils** has (guess what... {sm;:?:}) various functions for use
with CGI.
It contains functions to do things that every CGI has to cope with.
They are
most useful for simple scripts, where a full blown framework would be
too
cumbersome.
It includes (amongst other thing) :
* Functions for receiving form submissions
* Cross platform functions to send emails (including creating
{acro;HTML}
emails)
* A basic templating system
* A {acro;DNS;Domain Name System} blacklist lookup
* A function to generate a menu line for pages with lots of results
See the `cgiutils Homepage
http://www.voidspace.org.uk/python/cgiutils.html`_.

Double decoding of strings??
Hi all,
I have a bit of a problem. I'm trying to use Python to work with some
data which turns out to be garbage. Ultimately, I think the solution
will be to .decode('utf-8') a string twice, but Python doesn't like
doing this the second time. That could possibly be understandable, but
then why does the unicode object have a .decode() method at all?
I get 'WVL Algemeen Altru\xc3\x83\xc2\xafsme genormeerd Afbeelden' at
first.
I .decode('utf-8') this to u'WVL Algemeen Altru\xc3\xafsme genormeerd
Afbeelden'.
I then try to .decode('utf-8') this again, but that gives an error:
Traceback (most recent call last):
File stdin, line 1, in ?
File C:\Program Files\Python\lib\encodings\utf_8.py, line 16, in
decode
return codecs.utf_8_decode(input, errors, True)
UnicodeEncodeError: 'ascii' codec can't encode characters in position
18-19: ordinal not in range(128)
If I copy/paste 'WVL Algemeen Altru\xc3\xafsme genormeerd Afbeelden'
and try to .decode('utf-8') it, that works fine, and it gets me the
result I want, which is u'WVL Algemeen Altru\xefsme genormeerd

Why does it work this way? How can I make it work?

appending messages in imaplib
So I have the unfortunate task of migrating several hundred users from
local mail (mbox and mh) up to an exchange server as part of wearisome
SOX compliance nonsense.
I thought the best path through this thicket would be to knock up a
quick python script using imaplib to replicate folder structures on the
IMAP server and copy the mails accross.
Accessing the IMAP server is great. I can log in, search for mail,
change folder and fetch mail. but I just can't seem to get .append() to
work. Here is a quick example.
server = IMAP4(mail01)
server.login(huw-l,x)
('OK', ['LOGIN completed.'])
server.create(Migration)
('OK', ['CREATE completed.'])
#using a mail client I can verify that the folder was created
server.select(Inbox)
'OK'
r,data = server.fetch('220','(RFC822)')
#data now contains a real mail message off the server
message = data
server.append(Migration,None,None,message)
at which point it just sits there and does nothing. Any ideas greatly
appreciated. I'm assuming that it has something to do with the way I'm
passing it the message but I don't really know where to go from here.
Thanks,
Huw

Re: XML and namespaces
Alan Kennedy:
These namespace declaration nodes, i.e. attribute nodes in the
xml.dom.XMLNS_NAMESPACE namespace, are a pre-requisite for any
namespaced DOM document to be well-formed, and thus naively
serializable.
The argument could be made that application authors should be protected
from themselves by having the underlying DOM library automatically
create the relevant namespace nodes.
But to me that's not pythonic: it's implicit, not explicit.
My vote is that the existing xml.dom.minidom behaviour wrt namespace
nodes is correct and should not be changed.
Andrew Clover also suggested an overly-legalistic argument that current
minidom behavior is not a bug.
It's a very strange attitude that because a behavior is not
specifically proscribed in a spec, that it is not a bug. Let me try a
reducto ad absurdum, which I think in this case is a very fair
stratagem. If the code in question:
document = xml.dom.minidom.Document()
element = document.createElementNS(DAV:, href)
document.appendChild(element)
DOM Element: href at 0x1443e68
document.toxml()
'?xml version=1.0 ?\nferh/'
(i.e. ferh rather than href), would you not consider that a minidom
bug?
Now consider that DOM Level 2 does not proscribe such mangling.
Do you still think that's a useful way to determine what is a bug?
The current, erroneous behavior, which you advocate, is of the same
bug. Minidom is an XML Namespaces aware API. In XML Namespaces, the
namespace URI is *part of* the name. No question about it. In Clark
notation the element name that is specified in
element = document.createElementNS(DAV:, href)
is {DAV:}href. In Clark notation the element name of the document
element in the created docuent is href. That is not the name the
user specified. It is a mangled version of it. The mangling is no
better than my reductio of reversing the qname. This is a bug. Simple
as that. WIth this behavior, minidom is an API correct with respect to
XML Namespaces.
So you try the tack of invoking pythonicness. Well I have one for
ya:
In the face of ambiguity, refuse the temptation to guess.
You re guessing that explicit XMLNS attributes are the only way the
user means to express namespace information, even though DOM allows
this to be provided through such attributes *or* through namespace
properties. I could easily argue that since these are core properties
in the DOM, that DOM should ignore explicit XMLNS attributes and only
use namespace properties in determining output namespace. You are
guessing that XMLNS attributes (and only those) represent what the user
really means. I would be arguing the same of namespace properties.
The reality is that once the poor user has done:
element = document.createElementNS(DAV:, href)
They are following DOM specification that they have created an element
in a namespace, and you seem to be arguing that they cannot usefully
have completed their work until they also do:
element.setAttributeNS(xml.dom.XMLNS_NAMESPACE, None, DAV:)
I'd love to hear how many actual minidom users would agree with you.
It's currently a bug. It needs to be fixed. However, I have no time
for this bewildering fight. If the consensus is to leave minidom the
way it is, I'll just wash my hands of the matter, but I'll be sure to
emphasize heavily to users that minidom is broken with respect to
Namespaces and serialization, and that they abandon it in favor of
third-party tools.

It's your life, so you can live it as you choose, but I think you're missing the point of an undergraduate education if you focus too much on Python programming at this point. Undergraduate education is (should be) about breadth. Python has a place there, but it isn't the be-all, end-all. There are some concepts for which Python isn't well suited in teaching (functional programing, logic programing, operating system programing, etc.). I'd hope that you go to a high-quality University that understands this, and teaches *concepts*, not programing languages. In the long run, it will (likely) be better for you to go to a University where they don't even use Python, but solidly teach concepts, rather than one that's so into Python that they neglect topics that are taught poorly in Python. Even if you never use Python as an undergraduate, if you have a good grounding in the fundamental concepts, it should be (relatively) easy for you to take what you've learned in (scheme/ML/prolog/assembly/forth) and apply it to Python.

Always try the Title search first, as it only searches page titles. If that is unhelpful, then try the Text search. That searches the bodies of the pages. I generally never use that search, preferring instead to use Google's site:wiki.python.org ... restricted search which is going to apply their page rank algorithms to the hits (and be faster to boot).

There are plenty of people on this list willing to rurpy sing python's praises, for balance, there should be people rurpy willing to openly point out python's flaws. Documentation is rurpy certainly one of them. And I was correcting a posting that rurpy explicitly said there was exceptionaly good information in that rurpy Howto. That was just plain wrong. Sure, feel free to point of flaws. Just don't let that be the only way you contribute. Over time the value of your criticism (valid or not) will be discounted. The preferred way to correct problems with the documentation is to submit a bug report to SourceForge. Many of the active developers (including those who do write most of documentation) don't necessarily track c.l.py closely, so postings here often will get lost because people can't attend to them immediately. The problem with marching in here and saying fix the docs is that you are an unknown quantity (I certainly don't recognize your email address and as far as I've seen you never sign your posts. I don't believe I've ever seen contributions from you either. (Can't double-check right now because SourceForget is basically unresponsive.) The combination makes you look suspiciously like a troll. I doubt that's the case. Troll detectors are notorious for generating false positives. Still, my threat assessment level got raised. Operating under the rurpy's-not-a-troll assumption, your posts suggest to me that you don't understand how Python is developed. Behind the scenes lots of documentation *does* get written. In my experience it hass generally not been written by people who whine, fix the docs. In short, there seems to be no shortage of people willing to castigate the Python developers for poor documentation. There does appear to be a shortage of people willing to actually roll up their sleeves and help. The other thing to remember is that most of the people who wind up writing the documentation don't personally need most of the documentation they write. After all, they are generally the authors of code itself and are thus the experts in its use. It's tough to put yourself in the shoes of a novice, so it's tough to write documentation that would be helpful for new users. It's extremely helpful if new users submit documentation patches as they figure things out. It's generally unnecessary to write large tomes.

Bigger indentation steps *are* more obvious, but on the other
hand, smaller indentation allows you to use more indentation
levels without using up all of your line width. (Using more than
80 chars per line is typically a bad idea.)
In general, I find that you rarely need so many indentation
levels in Python as in e.g. C or C++. I rarely run out of line
width in Python, even though I use 4 space indents and use fairly
long names. Remember that you can freely break lines within pairs
of (), [] and {}, and that adjacent string literals are concatenated.

To connect to the application I use:
class MyApp_InterfaceManager (Thread):
...
def run (self):
# First we initialize the COM libraries for current thread
pythoncom.CoInitialize()
#Then we connect to the app with event handling...
self.app = DispatchWithEvents('MyApp',MyApp_AppEvents)
class MyApp_AppEvents:
OnHalt:
print halt event...
From here all is ok when the OnHalt event arrives the print is called.
The problem I have is that I need that MyApp_AppEvents class knows the
thread object to call a thread function when the event occurs(for
example I need to toggle a flag)
I've got no idea how to do that!
Anyone has encoutered the problem?
I've tryied to use getevents but with no result...

Re: Bitching about the documentation...
Sure, feel free to point of flaws. Just don't let that be the only way you contribute. Over time the value of your criticism (valid or not) will be discounted. bonono That is quite interesting, if it is true. Let me rephrase. The discounting I referred to is largely subconcious. When it is concious it's a roll of the eyes or a thought like, Oh that whiner again. I don't have time for this right now. And the 'd' key gets hit. I didn't mean to imply some sort of smoke-filled backroom where the developers decide whose inputs to listen to. Everybody applies such filters whether they think about it or not. Here are a couple of mine: Xah Lee? Hit the 'd' key. Tim Peters? Read it no matter what the subject says. Skip -- http://mail.python.org/mailman/listinfo/python-list
Re: ANN: Dao Language v.0.9.6-beta is release!
If someone doesn't want to give Python a second look because of their own bigoted ideas, I say Python doesn't want that type of person to begin with. Some days I feel the same way. I've described Python as a filter where only the best get through. That's leads to a concentration of talent and good taste which has great value and can even eclipse any shortcomings in the flawed tool that initially drew the crowd together. This is from a paper I started a long time ago, entitled The Value of Bad Design. I never finished it but I do think it might be valid. John -- http://mail.python.org/mailman/listinfo/python-list
