Making tabs meaning anything had the pretty obvious implication of making tabs meaning nothing. - stick to 4-space indent I've even run in the past in editors that damaged my python sources because they were indented with two spaces (I'm used to an indent size of 2 when working in C/C++).

'Deep' pickling
Hi,
I have some problems when pickling an instance of a class, i don't
retrieve all its attributes instances after loading. I'm quite a
beginner in Python, so it may be a stupid error... Here the full
description :
I have a class Test, having an attribute self.problem, as an instance
of Problem class, defined in the same module.
Problem as an attribute self.optimum, that is a list of Point
instances, also defined in the same module.
So i use to write self.problem.optimum[i] to get some Points of my
Test...
I pickle a Test with the following lines :
import copy
cPickle.dump( copy.deepcopy(self), open('TEST', 'w'))
and unpickle in another module with :
fd = open( os.path.join(p, 'TEST'), 'r' )
s = cPickle.load( fd )
But the problem is, when i try to access the self.problem.optimum
field, i get an empty list, instead of having a list full of Points. I
can access string, int, or even Point attributes of Problem. This only
happens when i load AFTER restarting Python interpreter.
I thought that pickling self from my Test wasn't enought to get
instances of attributes copied to, that's why i used a deepcopy(self)
instead, but it didn't resolve my problem... I tryed to define a
__getState__() method, but didn't help...
Can someone help ?

Outlook COM: how to create a MailItem from a .msg file

I linked it to python24.lib (under eclipse cdt/win2k) and it compiles,

The problem is when I try to debug it (gdb). I cannot go single
stepping into the code, more than one threads seem to be running, I get
messages like No source file named d:/workspace/pyTest/main.cpp, and
if I set a breakpoint to the function Fotis_root then I cannot see any
variables. In fact I cannot see no stack, no registers nothing, within
this function!
With msvc 6.0 debuging goes smoothly.
Any ideas?

If you're doing heavy functional programming, listcomps are tremendously unwieldy compared to map et al. Interesting; could you post an example of this? Whenever I try to think of that, I come up with unwieldly syntax for the functional case. In purely functional code the results of map/filter/etc would probably be directly used as arguments to other functions, which might make the calls longer than I'd consider pretty. This is especially true with lots of lambda-ing to declare temporary expressions. I suspect you're misunderstanding what I mean by heavily functional. You appear to see maps and listcomps merely as a shortcut for a for loop. You're comparing the map shortcut and the listcomp shortcut and seeing which one's less verbose. In a mostly procedural program which uses functional constructs in isolation, listcomps are going to win most of those battles. Heavily functional programming is a different mindset altogether. In heavily functional programming, things like maps and filters and function applications are actually what you're thinking about. map isn't an indirect way to do a for loop; it's a direct way to do a map. When your mind is focused on applying a function to each member of this list and returning a list of the results as opposed to convenient shortcut to a for loop, map is going to be far superior to a listcomp. And when you're doing dozens and dozens of maps over a large purely functional program, you don't want to write out a listcomp every single time you want to do it. -- CARL BANKS -- http://mail.python.org/mailman/listinfo/python-list

Re: Embedding performance.
amit wrote: Is there any kind of performance differences to the different ways of embedding python? PyEval_EvalCode() PyRun_SimpleFile() PyObject_CallObject() AFAIK, these are only different wrappers, while you're generally getting at the same functionality. I assume you're somewhat familiar with the Python API. What you're saving using the third one is parsing and compiling time, since the other two functions do it every time they're called, I believe. With PyObject_CallObject() you already have the PyObject, so it just goes straight to the interpreter core, and does not do any parsing and compiling. That said, you have to get the object from somewhere first, possibly using the other two :), which may not apply if you're calling something embedded (that is, written in C). A quick look in the Python sources brings up the following: PyRun_SimpleFile: adds __main__. sets __file__. looks for .pyc or .pyo files, loads the code object from them, or parses text, and finally calls PyEval_EvalCode with the code object. So there, you have the overhead. PyObject_CallObject: goes through some redirection to PyObject_Call, which calls obj-ob_type-tp_call directly. PyEval_EvalCode: checks for globals, checks for arguments, creates a frame with all the necessary stuff, checks for generators, calls PyEval_EvalFrame() which does all the dirty running of python code. So there, the least overhead seems to be in CallObject. Don't treat this as an authoritative answer, though.:) -- http://mail.python.org/mailman/listinfo/python-list

How old style? Basic has changed a lot over the years. ;-) But seriously, I think I know what you mean. I'm going to suggest that you try going very low tech with this and don't use an IDE at all. I'm sure you have some form of window environment (X, Windows, or Mac) and can open a terminal and an editor of your choice on screen (even if it's Notepad). Start the Python interpreter up in the terminal by just typing python. In the interpreter you can try simple one or two liners. You can even define a short function and try it out. But you'll get annoyed by having to up-arrow and retrieve lines one- by-one to repeat the function after you've made a mistake, so that'll get old for anything more than 5 lines long. So, use your editor. Type up a short program that you want to test in the editor, then copy and paste it into the Python interpreter. This way, when you (inevitably) find mistakes, you can just tweak them in the editor and then paste them again. You can, of course, paste statements from the interpreter back into your editor, but you'll have to avoid the prompts (or delete them), so it's usually better to write in the editor and paste into the interpreter. And when you're done, you can just save the result to file so you can get it back later. My point is, you don't have to use a fancy all-in-one application to do the job, nor must you run your programs from within your editor. It's not so hard to just use tools you already understand. Personally, I did things like this for years, and still do from time to time. I've hardly ever used an IDE, and I'm still not totally convinced they are worth the effort involved in learning them. I used to hop from computer to computer a lot, and if I tried to learn my way around separate IDEs on Macs, Windows, DOS, Solaris, and Debian Linux, I would've spent a lot of time twiddling with the tools instead of just writing code. Lately, I've settled into using Vim, which is nice editor (especially if you once wrote a several thousand line program in Vi with nothing but a fold-up quick reference for a manual ;-) ). There may well be friendlier ones, but I know this one fairly well, and it has a pretty large community of developers who are constantly tweaking it to make it a better editor for programming. I only just recently started seriously customizing it to work well with Python, though. You can always go shopping for an IDE to buy into heavily *after* you've learned the language. Meanwhile, don't let trifles get in the way -- just use your window system as your IDE. That way, you can pick the editor to suit you. And the Python interpreter is great, it will give you no trouble and quick answers. -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com -- http://mail.python.org/mailman/listinfo/python-list

precision problems in base conversion of rational numbers
Hi all, I guess it is more of a maths question than a programming one, but it involves use of the decimal module, so here goes: As a self-directed learning exercise I've been working on a script to convert numbers to arbitrary bases. It aims to take any of whole numbers (python ints, longs, or Decimals), rational numbers (n / m n, m whole) and floating points (the best I can do for reals), and convert them to any base between 2 and 36, to desired precision. I'm pretty close but I know I am not handling the precision quite right. Nothing other than understanding hangs on it, but, that's enough :-) To do all this I'm using the decimal module (for the first time) and I've been setting the precision with decimal.getcontext().prec = max(getcontext().prec, x * self.precision ) This is in my class's __init__ method before I convert every number to Decimal type and self.precision is at this point an int passed. The first term is to be sure not to reduce precision anywhere else. In the last term I'd started off with x = 1, and that works well enough for small cases (i.e. cases where I demanded a relatively low degree of precision in the output). I've no idea how to work out what x should be in general. (I realize the answer may be a function of my choice of algorithm. If it is needed, I'm happy to extract the relevant chunks of code in a follow-up -- this is long already.) For getcontext.prec = 80 (i.e x = 1) when I work out 345 / 756 in base 17 to 80 places (i.e. self.precision = 80) I get: print Rational_in_base_n(345, 756, 17, 80) 0.7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0D5C1G603999179EB (Rational_in_base_n(numerator, denominator, base, precision) is the rational specific subclass. When I convert the result back to decimal notation by hand it agrees with the correct answer to as many places as I cared to check.) I've discovered empirically that I have to set getcontext.prec = 99 or greater (i.e. x = 1.2375) to get 0.7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7CF0CA7C (I do feel safe in assuming that is the right answer. :-) How would I go about working out what degree of precision for the decimal module's context is needed to get n 'digits' of precision in an expression of base m in general?

(That is not the same question as asking if the two flags have the same value.) Huh ? Equality *is* the answer to whether two things (flags or whatever) have the same value or not. What else could it be ? Certainly not whether they are *the same*; you have the 'is' operator for checking identity. In any case, done_processing == more_reading_needed is perfectly valid and most people would agree that if the result is True, done_processing and more_reading_needed are equal. It gets worse. Consider this example of logic: x = log(-5) # a NaN y = log(-2) # the same NaN x == y # you want this to be true for NaNs Then: # compare x and y directly log(-5) == log(-2) # if x == y then exp(x) == exp(y) for all x, y exp(log(-5)) == exp(log(-2)) -5 == -2 Such paradox cases can be avoided if the only operations defined for NaNs are equality/inequality; all others yield NaN too. That is, exp(NaN) is NaN, as it is log(NaN), 3**NaN / 5i and so on. Think of NaN as a black hole that absorbs and assimilates what falls into it, so log(-5) and log(-2) are just NaN, they lose their identity as two distinct things, log(-5) and log(-2). Similarly, if z=0/0, z would also be invalid, but different from x and y, since it is the result of a different invalid operation. This brings us to the many-NaN situation. The problem is, the many NaNs in the IEEE standard (or at least Apple's implementation of it) refer to _kinds_ of NaNs, not NaNs themselves. log(-2) is not the same not a number as log(-2.0001), or log(-2.3). They might be the same kind of failure, but that's it. That's absolutely fine; as long as two things are invalid and they're invalid for the same reason (kind of failure), they are equal to me. Having given reasons why it is utterly bogus to be comparing NaNs for equality, I will say this. Practicality beats purity. If you can demonstrate a good usage case for testing equality with NaNs, I will accept that it is a good thing to do. if x in (SOME_NAN, SOME_OTHER_NAN, ANOTHER_NAN, \ YET_ANOTHER_NAN, AND_ANOTHER_NAN, ..., \ # 240+ more NaNs listed ALMOST_FINISHED_NOW, LAST_NAN): print Calculation failed! is _not_ a good usage case, since it is best handled with: if isNan(x): # handled by the floating point package print Calculation failed! Agreed on that, if all you need to know is if the outcome of an expression is valid or not. But since a NaN can be thought of as a flag representing the fact that an error occurred, as you mentioned, it makes sense in practice to ask whether two errors are of the same kind, e.g. for handling them differently. If I understood correctly, your objection is using the equality operator '==' with these semantics for NaNs. I would say that it's a reasonable choice for practicality beats purity reasons, if nothing else. George -- http://mail.python.org/mailman/listinfo/python-list

RE: Unicode drives me crazy...
[EMAIL PROTECTED] | I want to get the WMI infos from Windows machines. | I use Py from HU (iso-8859-2) charset. OK, there are people better placed than I to explain about Unicode. Check out the following article, for example: http://www.joelonsoftware.com/printerFriendly/articles/Unicode.html but in short, you need to understand that WMI hands you back a unicode object -- not a string, a unicode object. If you want to write that out to a file, you must write out a string representation of it. And that string representation must use one of the standard encodings (or you could invent your own, I suppose, but why bother?). One way of doing this would be: code import wmi import codecs f = codecs.open (c:/temp/info.txt, w, encoding=iso-8859-2) try: c = wmi.WMI () for port in c.Win32_SerialPort (): f.write (Caption = %s\n % port.Caption) f.write (DeviceID = %s\n % port.DeviceID) finally: f.close () /code You now have a text file -- info.txt -- which holds string representations of several unicode objects. If the characters all fall within the common A-Z/1-9 characters, it will appear just the same as an old-fashioned ascii file. If the original data represented (presumably) Hungarian characters, there will be some representation of that, probably using \x sequences. This file can be read by any other program which knows that it's an iso-8859-2 encoding of unicode. (Knows, because you write the program or because you've told the programmer). Obviously, if this were an XML file, you would put an encoding tag or whatever it's called (I'm not up on XML). TJG This e-mail has been scanned for all viruses by Star.

How to I convert every objects to string, and convert (encode) them to
iso-8859-2 (if needed) ?
s is a 'byte string' - a series of characters encoded in bytes. (As is
every string on some level). In order to convert that to a unicdoe
object, Python needs to know what encoding is used. In other words it
needs to know what character each byte represents.
See this :
t = s.decode('iso-8859-1')
t
u'Kommunik\xe1ci\xf3s port (COM1)'
print t
Kommunikációs port (COM1)
print type(s)
type 'str'
print type(t)
type 'unicode'
The decode instruction converts s into a unicode string - where Python
knows what every character is. If you call unicdoe with no encoding
specified, Python reverts to the system default - which is *probably*
'ascii'. You string contains characters which have *no meaning* in the
ascii codec - so it reports an error
Does this help ?
Once you 'get unicode', Python support for it is pretty easy. It's a
slightly complicated subject though. Basically you need to *know* what
encoding is being used, and whenever you convert between unicode and
byte-strings you need to specify it.
What can complicate matters is that there are lot's of times an
*implicit* conversion can take place. Adding strings to unicode
objects, printing strings, or writing them to a file are the usual
times implicit conversion can happen. If you haven't specified an
encoding, then Python has to use the system default or the file object
default (sys.stdout often has a different default encoding than the one
returned by sys.getdefaultencoding()). It is these implicit conversions
that often cause the 'UnicodeDecodeError's and 'UnicodeEncodeError's.

KeyError: 'setup'
does anyone know how I can circumvent this?
3. Is there any way to set the __name__ attribute for the inspected

__main__, so that tracing is really transparent?
4. finally, does a functionality like this already exist in the library

I want to get the WMI infos from Windows machines.

How to I convert every objects to string, and convert (encode) them to
iso-8859-2 (if needed) ?
Please help me !
As Tim Golden already explained, you're getting a unicode
object from the WMI interface. The best design help I can
give is to either convert it to iso-8859-2 at the point you
get the object and do your entire program with iso-8859-2
encoded strings, or do your entire program with unicode
objects and encode them as iso-8859-2 strings whenever
you want to write them out. Trying to do your conversion
in the middle will lead to excessive complexity, with the
resulting debugging problems.
If you do go the unicode route, you must remember that
any method or function that's defined to return a string will
most likely throw an exception. This includes str()! Whether
or not the print statement will work depends on a number
of factors in how your Python installation was set up.

Obtaining glyph width in Python
Hi, I'm looking for a way to obtain the width of a string, either in actual inches/centimeters, or pixels will also work. Unfortunately this seems difficult as I'd like to keep things as close to the stock Python install as possible, and I'm not working with Graphics or X at all. Here are the options I've found, and why they're less than optimal for my use: PIL = Huge for only using one function. I'm not working with any graphics. PyFT = Everyone uses FreeType2 now, and PyFT seems dead anyhow. PyFT2 = Does not exist. tkinter.text() = Works with X, creates windows no matter what you do. t1lib = Separate package, no TTF support. t1python = Same thing as t1lib? Ultimately, I'm looking to take a stream of text, and break it up into lines based on page width... and I need to know how wide (and ultimately how tall, for page breaks) the individual glyphs are so I can break properly. If there's an easier way to do this than calculating individual glyph width, I'm open to that too. I was really just looking to see if there was anything out there that wasn't too large or too obscure/dated. Maybe there's something lower level that could be done to achieve this?

2. Breakpoint at line 13: When I finally reach the much awaited line
34, the python interpreter is there and running and waiting for my
commands, which here is the fotis.root(double) command. when I give

not know where I am, why am I there, and what exactly I am doing at the
point that I am.

Re: python project layout
Huron wrote: Hi Peter, Thanks for you detailed reply. The layout that you suggest sounds wise to me (I'm about to start a project). I wouldn't necessarily recommend something so complex (not that it's particular complex, but it's more than just flat) for a newcomer, however. One of the few small issues you have to deal with in order to get such a layout working properly is the python path issue, and how to import modules that are in another folder. Normally (aside from the standard library and extensions) only the current directory is in sys.path. Any subfolders that contain __init__.py modules are packages and you can import from them using the dotted notation (e.g. import mypkg.mymodule will try to load a file from ./mypkg/mymodule.py if there is also a ./mypkg/__init__.py (even if that file is empty!)). To import a module in the *parent* directory, however, is another story entirely. You need to get it added to the sys.path, and that's one of the things done (dynamically) by our test utilities, so we can be in the tests subfolder and type story015.py and have it load modules in the parent folder. So in short, start simple and let your layout evolve as you need it to. Don't try to start with a more complex layout than you need or know how to handle. And if you're using a revision control system like Subversion (and you better be using something! :-) ) then it's an easy matter to rename or move folders at a later time, without losing your revision history. -Peter -- http://mail.python.org/mailman/listinfo/python-list

Read the manual for the precedence rules. -x**y groups as -(x**y). -1.0 is the correct answer. If you intended (-x)**y, then you need to insert parentheses to force that order. So i see. Any idea why that precedence order was chosen? It goes against conventional mathematical notation, as well as established practice in other languages. Eh? For example, Fortran and Macsyma also give exponentiation higher precedence than unary minus. From my POV, Python's choice here was thoroughly conventional. I guess you're right. What really threw me is that in all the other languages i know (which is not many, i admit), -1 is a literal -1, not a literal 1 plus a unary minus. Also, would it be a good idea for (-1.0) ** 0.5 to evaluate to 1.0j? It seems a shame to have complex numbers in the language and then miss this opportunity to use them! It's generally true in Python that complex numbers are output only if complex numbers are input or you explicitly use a function from the cmath module. [...] The presumption is that a complex result is more likely the result of program error than intent for most applications. The relative handful of programmers who expect complex results can get them easily, though. A reasonable presumption.

IOError: [Errno 2] No such file or directory: '/hwinfo.ini'
When I use full path: c:\dev\\Dialog1.exe, it have been found
everything, and working good.
I don't understand it, because I working with sys.argv[0], with this method:
def LoadIniFile():
s=os.path.dirname(sys.argv[0])+'/hwinfo.ini'
f=open(s,'r')
l=(f.read()).split('\n')
d={}
for s in l:
if s.find('=')-1:
sl=s.split('=')
sl[0]=sl[0].strip().lower()
sl[1]=sl[1].strip()
d[sl[0]]=sl[1]
return d
So that folder is must be correct !
Why I get error ? What I can do if I want to use it as normal py ?
Thanx for help:

Re: Where can I get the new version of python-mode for emacs?
Marcio I have version 4.70 installed in my debian system (installed Marcio with apt-get, so I don't know where the sources are from). After Marcio reading the thread_ at sourceforge, I did a google search for Marcio python emacs and found the `Emacs goodies`_ page at python.org Marcio .. _`Emacs goodies`: http://www.python.org/emacs/ Marcio where I was redirected to the `python-mode`_ page at Marcio SourceForge. There I could only find version 1.0alpha (4.6) (the Marcio one said too old in the thread_) I haven't done a release in a long while. Guess it's about time to do that again. In the meantime, you can download the currently most recent version of python-mode.el from here: http://cvs.sourceforge.net/viewcvs.py/*checkout*/python-mode/python-mode/python-mode.el?rev=4.75 You can browse all the files in the CVS repository here: http://cvs.sourceforge.net/viewcvs.py/python-mode/python-mode/ Skip -- http://mail.python.org/mailman/listinfo/python-list

Re: python project layout
A concrete example would probably help. What are you envisioning? Let say you have an interface (zope.interface) IMyProduct and two classes implementing the interface MyProduct1 and MyProduct2 ...

Re: What are the other options against Zope?
It's an object oriented database, with a structure that is similar to files and directories in an ordinary OS. But it is a lot smarter, because the files and directories are actually objects with different attributes and parameters. The methods on these objects can then be called eg. from a web browser with different parameters. But you can also use other protocols than http like dav, ftp etc. Well, that's interesting. I've never seen an explantion like this. Actually I think I have, and was too dumb to realize what I was reading. A data base with properties and methods.

Thanks for all the input. Three weeks later I stumble across this thread again and notice I didn't report what I ended up with.

Try Emacs + python-mode. Emacs surely has a lot of warts, but I'm still
looking for a better and more versatile code editor/IDE - specially when
it comes to languages with REPL (- Read-Eval-Print Loop).
When you build Python, make sure you build it with Gnu readline support.
Then you can just fire up an interpreter, and use emacs (or, I suppose, vi)
editing commands to scroll back through (and change) your input history.
It's not as good as a real IDE, but it's still very handy for quick
explorations.
The next step up would be to run a real emacs, do M-X shell, then fire up a
Python interpreter inside that.
Or, go into split screen mode in emacs, editing your python source file in
one window and running a shell in the other. Edit some code in the source
window, and it takes about 6 keystrokes to save it, flip to the other
window, and re-run the file (you can get it down to a single keystroke by
defining a simple macro and binding it to a function key).
Err... actually, using python-mode is *way* more simple:
[ctrl+c ! to launch the REPL (this splits the frame) if it's not already
running]
[ctrl+x o to go back to the source code buffer]
then
ctrl+c ctrl+c to execute the whole buffer in the REPL
or
select a region then ctrl+c ctrl+l to execute the selected region in the
REPL
Of course, the REPL now reflect any changes made into the source code
buffer (even if changes have not been saved) !-)
