Re: Corectly convert from %PATH%=c:\\X; "c:\\a; b" TO ['c:\\X', 'c:\\a; b']
Its good to see what cpython did with the PATH. I now feel good about taking the simple approach. It would be crazy if that sort of quoting in the middle becomes something which works with too many applications - and others are expected to keep up with it. I guess I dont need to worry about unix PATHs now. Thanks, Chirayu. -- http://mail.python.org/mailman/listinfo/python-list

DIY Spam Filter in Python
Hi all, I've no idea if this will be of any use to anyone. But since I've gone to the effort of writing it, I might as well make it publicly available... Until last year, spam filtering was a source of frustration for me. Freeware packages I tried (specifically, spamassassin and dspam) were difficult to use. Custom rules using procmail were a pain. Then I noticed that python came with email parsing capabilities in the email module. So I thought that maybe custom rules in python would be easier than (a) custom rules in procmail, or (b) deciphering the documentation of a package. And a lot more fun. It turned out to be very easy. I got the filter up in a few evenings, and I've been using it successfully, and slowly enhancing it, over a number of months. In short: a success story for "using the batteries" - at least in my opinion.

I can't answer you this one without looking at the actual code, but 2. You can never call any methods/classes which you imported in a "parent" module (actually, there's no such motion as parent module, as each module has its own namespace, and references to this namespace may appear anywhere else in another module). In case this worked sometime ago and you didn't explicitly import the module in the "child" module, you silently did something like the following: Mod1.py --- import Numeric import Mod2 # Put the namespace (module object) in another namespace Mod2.Numeric = Numeric Mod2.py --- What you need for your simulation program is probably something like the following: Simulation.py - import MyFiles import Branches import Numeric print MyFiles.Branches is Branches # True print MyFiles.Numeric is Numeric # True print Branches.Numeric is Numeric # True MyFiles.py -- import Branches import Numeric print Branches.Numeric is Numeric # True Branches.py --- import Numeric HTH! -- --- Heiko. listening to: aenima_13_aenima.mp3 see you at: http://www.stud.mh-hannover.de/~hwundram/wordpress/ pgp3EJqOZ4rfI.pgp Description: PGP signature -- http://mail.python.org/mailman/listinfo/python-list

Sending keytrokes to Windows app
Hello, I am trying to control a Windows application from a python script with SendKeys and Python 2.3. My problem is that the characters ':' and '\' are sent to the application as ';' and '+'. See code example below. I suspect that the problem has to do with the regional and keyboard settings in Windows. I am using the setting English (UK) with Finnish keyboard. If I change the settings to English (US) with US keyboard, everything works fine. Is there a way to either change the language and keyboard settings from my python script, or get Sendkeys to send the characters correctly? Or should I use another way to send the keystrokes to the application?

Nearly - you don't need the text=f.readline() bit. A file object (as returned to you by open()) is an iterator, and iterating over it gives you the lines directly. Why not give it a go?

For regular talks, we have the following tracks: Business Education Python Frameworks Python Language Science Social skills and General Topics Zope/Plone We also have a special track for "Misfits" this year. It is for any topic that is Python related but doesn't fit in any of the above categories. Last day for submitting talks to the regular tracks is 1 May 2005. On top of this, we will have two tracks of Lightning Talks; one for Zope/plone and one for other topics. You can register talks for these all the time until the Lightning Talk sessions end, or the schedule is filled, whichever comes first. Europython 2005 will be held 27-29 June at the Chalmers University of Techchnology, Göteborg, Sweden. Registration will open in mid-April. We hope this will become the best Europython Conference ever! With your help it can. We are still seeking volunteers to help us with a number of things.

The idea was to be able to create a Rational() from a float using a given upper bound on the denominator. The standard Rational() constructor already provides a way to construct a rational out of a Python or mxNumber float, but always uses maximum precision - which may not always be what the user wants (e.g. to work around rounding errors). Thanks for posting your faster version.

adodbapi return value
I'm trying to use the adodbapi module, but run into the following
problem:
After initalization (connection, cursor) I have the following call to
a stored procedure (SQL Server, using SQLOLEDB.1 provider).
m = u'BrReg'
rs = u''
msg = u''
x = self.cur.callproc('__DocFetchBaseCategories', (0, 0, m, rs, msg))
print x
>>> [0, 0, u'BrReg', u'', u'']
print self.cur.returnValue
>>> None
print self.cur.rowcount
>>> -1
The procedure is enclosed below. Strange thing is that if the
variable 'm' is set to an empty string, everything works ok, the
resultstate value (x[3]) becomes '_OK'. However having the variable
'm' set to 'BrReg' as indicated, seems to result in the returned set
(x) not being updated. When executing the Stored Procedure in Query
Analyzer, everything seems to be ok (BrReg is a valid value and
results in both '_OK' resultstate and a set of values (record set)).
When using the value m='', the returnValue when printed is 0.
FRAGMENT OF SQL CODE
create proc __DocFetchBaseCategories (
@TraceLevel int,
@UserId int,
@Module varchar(32),
@Resultstate varchar(121) output,
@Message varchar(255) output
) as
begin
if @Module <> ''
begin

from _DerivedCategories D, _Categories C
where D.Category like (@Module + '[_]%')
and not D.BaseCategory like (@Module + '[_]%')
and D.DerivedLevel = 1
and D.Category = C.Category
end
else
begin
select 1,
Category,
BaseCategory,
CategoryDescription
from _Categories
where BaseCategory = ''
end
select @ResultState = '_OK',

Re: (win32) speedfan api control

Thanks for the link to Winspector - with this tool it's really easy to find out the names required to get down to the window elements of a running application. In the special case of speedfan there seems to be no way to get the temperatures shown in Reading tab into a Python script, because the texts with the temperature values are not separate window elements. The only message sent to "TJvPanel" (it's the class of the element with the temperatures) is WM_PAINT with 0, 0 values, so the actual temperatures are "hidden" from beeing accessed as easy as the value of the checkbox. Knowing the rectangle of the "TJvPanel" it should be probably possible to OCR the text shown, but this is another story.

Semi-newbie, rolling my own __deepcopy__
Hi, folks, First, the obligatory cheerleading -- then, my questions... I love Python! I am only an occasional programmer. Still, the logic of the language is clear enough that I can retain pretty much all that I have learned from one infrequent programming session to the next. That's quite an accomplishment for a language this powerful. Also, I'm finally beginning to grasp OOP. I could never quite get the hang of it in C++ or Java. Recently, I discovered __getitem__ and pickle. Oh, yeah. Anyway, my present problem is that I want to make copies of instances of my own custom classes. I'm having a little trouble understanding the process. Not that I think that it matters -- but in case it does, I'll tell you that I'm running Python 2.3.4 on a Win32 machine. I started naively, thinking that I could just call copy.deepcopy() and be done with it. After getting a TypeError from the interpreter, I read the deepcopy docs and discovered that I need to implement a __deepcopy__ method in my class. But the docs are a bit vague here. What exactly should this __deepcopy__ do? I tried looking for examples of __deepcopy__ code on the Net, but I'm not quite understanding what I'm finding there. I guess that I'm getting deeper into the guts of Python than I planned. AFAIK, I'm supposed to add a "def __deepcopy__(self, memo):" to my class definition. This will get called when I invoke copy.deepcopy(myObject). The object to be copied is self, I presume. What exactly is memo? The docs say that it's a dictionary which "keeps track of what has already been copied." Somewhere I remember reading that the namespace of an object is a dictionary. So is memo identical to the dictionary of the new object that I'm trying to create? What exactly do I add to memo? I think that I should make shallow copies of methods, but deep copies of data structures (the contents of which I'm likely to change). Do I iterate through and copy the items in dir(self)? Do I update memo manually, or does passing memo into copy() or deepcopy() automatically update memo's contents? Are there any items that I *shouldn't* copy from self to memo? Should __deepcopy__ return memo? Sorry for all the confusion -- and thanks for your help! -- Rainforest laid low. "Wake up and smell the ozone," Says man with chainsaw. John J.

Re: "specialdict" module
About not using super: you might have problems in multiple inheritance. Suppose I want to use both your defaultdict and a thirdpartdict. A subclass class mydict(defaultdict, thirdpartdict): pass would not work if thirdpartdict requires a non-trivial __init__ , since without super in defaultdict.__init__ you would just call dict.__init__ and not thirdpartdict.

Re: re module non-greedy matches broken
how then, do i specify a non-greedy regex
<1st-pat>*?
that is, such that non-greedy part *?
excludes a match of <1st-pat>
in other words, how do i write regexes for my examples?
what book or books on regexes or with a good section on regexes would you
recommend?

Re: Semi-newbie, rolling my own __deepcopy__
[EMAIL PROTECTED] wrote:
Hi, folks,
First, the obligatory cheerleading -- then, my questions...
I love Python! I am only an occasional programmer. Still, the logic
of the language is clear enough that I can retain pretty much all that
I have learned from one infrequent programming session to the next.
That's quite an accomplishment for a language this powerful. Also, I'm
finally beginning to grasp OOP. I could never quite get the hang of it
in C++ or Java. Recently, I discovered __getitem__ and pickle. Oh,
yeah.
Anyway, my present problem is that I want to make copies of instances
of my own custom classes. I'm having a little trouble understanding
the process. Not that I think that it matters -- but in case it does,
I'll tell you that I'm running Python 2.3.4 on a Win32 machine.
I started naively, thinking that I could just call copy.deepcopy() and
be done with it. After getting a TypeError from the interpreter, I
read the deepcopy docs and discovered that I need to implement a
__deepcopy__ method in my class. But the docs are a bit vague here.
What exactly should this __deepcopy__ do? I tried looking for examples
of __deepcopy__ code on the Net, but I'm not quite understanding what
I'm finding there. I guess that I'm getting deeper into the guts of
Python than I planned.
AFAIK, I'm supposed to add a "def __deepcopy__(self, memo):" to my
class definition. This will get called when I invoke
copy.deepcopy(myObject). The object to be copied is self, I presume.
What exactly is memo? The docs say that it's a dictionary which "keeps
track of what has already been copied." Somewhere I remember reading
that the namespace of an object is a dictionary. So is memo identical
to the dictionary of the new object that I'm trying to create? What
exactly do I add to memo? I think that I should make shallow copies of
methods, but deep copies of data structures (the contents of which I'm
likely to change). Do I iterate through and copy the items in
dir(self)? Do I update memo manually, or does passing memo into copy()
or deepcopy() automatically update memo's contents? Are there any
items that I *shouldn't* copy from self to memo? Should __deepcopy__
return memo?
Sorry for all the confusion -- and thanks for your help!

Right. I thought about a combined defaultdict/keytransformdict,
which seems to be easy to create with the current implementation:
class defaultkeytransformdict(defaultdict, keytransformdict):
pass
At least I hope so. This is another argument against the initializing
of defaultfactory or keytransformer in __init__.

You might be able to use or borrow code from my process.py module. process.py is very similar to Python 2.4's subprocess. It provides a ProcessOpen class (similar to subprocess' Popen). A ProcessOpen instance has wait() and kill() methods that work fine on Windows.

dynamic partial mirror, apt-get fails
Hi everybody, I am trying to implement a cgi script for mirroring a small part of a large collection of files (the debian distribution). The idea is to mirror only those files which are requested, by downloading them "on the fly" when the clients request them. Requests in the form "wget http://local.mirror.pt/~debian/cgi-bin/get.cgi?pool/main/a/abcde/abcde.deb"; work fine already. The script get.cgi verifies if the file exists. If it exists, the script simply sends a "Location: ..." directive to its standart output and exists. If the file does not exist, the script downloads it from one of several predefined locations, and after the downloading process has succeeded it sends a "Location: ..." directive to its standard output and exits. This is more or less what apt-proxy (and other proxies) do, except that my script is independent of the directory structure (it should work for any collection of files, not only for the debian distribution) and it can be run by an ordinary user (you don't have to be root in order to install it). Now, the problem is that the debian package manager (dselect or apt-get) does not work exactly like wget. Requests in the form "apt-get http://..."; fail with the strange message "302 Found". I looked a little bit into the source of both wget and apt-get and it seems to me that wget has code which deals specifically with the "Location: ..." directive, while apt-get has not. The questions are: Is my conclusion above correct ? Are future versions of apt-get going to accept "Location: ..." directives ? Should I try and modify the source of apt-get in order to teach it to handle these directives ? You can find all the details about my problem at my web page: http://cmaf.ptmat.fc.ul.pt/~barbaros -> english -> computers and programming -> deb_part_mirr Thank you.

Eric3 under WinXP
Hello NG, (Win XP) I have successfully installed pyqt, but not qtext, which I need to run Eric3. The PyQT demo files run fine. I've downloaded QScintilla, compiled via MS-VC, but (I suppose I need the SIG), to translate or provide the Python interface with pyd Files. Eric complains, that qtext is not found. Has anyone success with getting this to work and how?

I know this is not your recipe, but is there any reason to use
self.__class__()
instead of
type(self)()
if you know you're inside a new-style class?
STeVe
I don't know - aren't they identical? I would write self.__class__ (without
claiming that that's better)
BTW, I had a different question about the method:
wouldn't:
result = self.__class__.__new__()
or in your form:
result = type(self).__new__()
be better (i.e., clearer and possibly safer) than calling __init__ twice (but I
haven't tried it!)

Re: re module non-greedy matches broken
with respect to the documentation, the module is broken. the module does not necessarily deliver a "minimal length" match for a non-greedy pattern.

We found the answer, just in case one was looking for it... I turns out that setting the environment params (CGI_PATH & CGI_LD_LIB_PATH) is not sufficient.

Depends on what you're printing on.
tty?
curses
os.popen('tput')
printer?
reportlab
> and hopefully without including any external modules.
I suppose you can pick an output device and hard-wire the
escape sequences into your code.

no - in the non-greedy regex

<1st-pat>, and are arbitrarily complex patterns.
with character classes and negative character classes you do not need
