ANN:NewEdit 3.2 Released
What's it?
It's an Editor based on wxPython. NewEdit uses Mixin and Plugin
technique as its architecture. Most of its classes can be extended via
mixin and plugin components, and finally become an integrity class at
creating the instance. So NewEdit is very dynamic. You can write the
new features in new files, and hardly need to modify the existing
code. And if you want to extend the existing classes, you could write
mixins and plugins, and this will be bound to the target class that I
call Slot Class. This technique will make the changes centralized
and easily managed.
What are its features?
* Cross platform
o based on wxPython, so it can run anywhere that wxPython
works, such as: Windows, Linux.
o Unicode support.
* Most features of wxStyledTextCtrl(Scintilla)
o Syntax highlighting, support Python, c/c++, html, plain
text, perl, ruby, css, javascript
o Folding
o Brace Matching
o ...
* Extended selection
o Extended word selection -- You can press
Ctrl+?MouseDoubleClick to select a word including '.'
o Matched selection -- Select text in quoted chars like:
(), [], {}, '', .
* Other editing extension
o Duplicating text -- Just like Vim Ctrl+V, Ctrl+P, and
more. You can duplicate above or below char, word, line
o Quoting text -- Add some quoted chars before and after
selected text, just as: , '', (), [], {}, and
o Text convertion and view -- python - html, reStructured
Text - html, textile - html, and you can output or view
o Utf-8 encoding auto detect
o Changing document encoding
oAuto backup
oLast session support -- It'll save all the filenames as
closed, and reopen the files as next started.
oSmart judge the indent char -- It'll auto guess the
indent char, and sets it.
oFinding in files
oBookmark support
* Python support
obuilt-in python interactive window based on ?PyShell,
support Unicode
oAuto completion
o Function syntax calltips
o Run, run with argument, stop python source
o Auto change current path
o Python class browser
* Code snippets
o You can manage your code snippets with categories, and
each category can have many items. Every item will represent a code
snippet. You can insert an item just by double-clicking on it. It even
supports importing and exporting.
* Simple project support
o Can create a special file _project, so every file and
folder under the folder which has the _project can be considered as a
whole project.
* Extension mechanism
o Script -- You can write easy script to manipulate the all
resource of NewEdit, just like: text conversion, etc.
o Plugin -- Customized function. More complex but more
powerful. Can easily merge with NewEdit, and can be managed via menu.
o Shell command -- Add often used shell commands, and execute them.
* Ftp support
o You can edit remote files through ftp. You can add,
rename, delete, upload, download file/directory.
* Multilanguage support
o Currently supports two languages: English and Chinese,
which can be auto-detected.
* Shipped plugins(must be configed as used them before)
o Document links -- Python documentation and wxPython documentation.
o Many plugins can be found at NewEdit wiki page.
* Shipped scripts
o Many scripts can be found at NewEdit wiki page.
* Wizard (New)
o You can make your own wizard template. The wizard can
input user data, combine with template, and output the result. And
wizard also support code framework created. This feature will help you
improving coding efficiency.
* Direcotry Browser(New)
o Browse multiple directories, and you can really add,
delete, rename directories and files. Double click will open the file
in Editor window.
* AutoComPlete(acp)(New)
o Suport user autocomplete file, it can help to input code
very helpful and functional. Just like EditPlus, but may be more
powerful.

ANN: Leo 4.4b1 released
Leo 4.4 beta 1 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458package_id=29106 The code is stable; there are no known serious bugs. Some features are incomplete. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name, with tab completion. - Many new commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. You can use Leo without using a mouse. - Flexible key bindings and input modes. You can emulate the operation of Emacs, Vim, or any other editor. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Dozens of other new features and bug fixes since Leo 4.3.3.

I noticed in the one footnote that the H.P. book had been translated into American. I've always wondered about that.

I thought it rather jarring. translated into American, I'm sure refers to the American version of the book, which is titled Harry Potter and the Sourceror's Stone. I find that bizarre. There is no mythological basis for a Sourceror's Stone, but the Philosopher's Stone, was of course the mythical Alchemists' goal of a catalyst for converting lead into gold (it had other properties, IIRC). Apparently the publisher was of the opinion that American children just aren't cultured enough to know about that, even though I knew the reference when I was 12. I am really, really insulted by that. They even went so far as to shoot two versions of every scene in the movie that referred to the stone so that it would agree with the book. AFAICT, you cannot purchase the original movie or book within the United States, and due to the Evil Conspiracy of region-coding, I couldn't watch the British DVD even if I were to import it (Well, yeah I could, but it would be painful, and probably illegal, do to that other Evil Conspiracy, the DMCA -- don't let your country pass a law like this).

Re: Arithmetic sequences in Python
Some ideas: 1) Let [a,b .. c] be *ordinary list* ! Just like [1,2,3]. Are there any questions why 3 is included in [1,2,3]? IMO it's more correct to think about [first, next .. last] as about syntax for list creation, but not as about syntax-to-replace-range-function. (And, because it's an ordinary list, you could iterate through it in usual way: for each element of list do...) 2) [5 .. 0] - [5,4,3,2,1,0] So, if next is omited, let the default step be 1 if first last and -1 otherwise. -- http://mail.python.org/mailman/listinfo/python-list

Re: exec a string in an embedded environment
No it didn't help me :(
the foo_ptr that is returned from PyRun_String is not a callable
object. Therefor I can't call it from PyObject_Call.
I would like to do the exact same procedure as I do when the code is
located in a module (file).
pModule = PyImport_Import(pName);
Py_DECREF(pName);
if (pModule != NULL) {
pFunc = PyObject_GetAttrString(pModule, inArg-funcName);
/* pFunc is a new reference */
if (pFunc PyCallable_Check(pFunc)) {
It must be possible to import a module written inside a string with a
similar approach. The ultimate solution would be to change the
PyImport_Import() call to something that creates an object from a
string
Now some of you think why not have the code inside a file. We need to
create encrypted script files, thats why.

Re: Shrinky-dink Python (also, non-Unicode Python build is broken)
Neil Hodgson wrote: - There will be some opposition to the obvious policy of keeping the bare minimum inside the DLL because of inefficiencies in the Python build system. It is also non-optimal for those that do want the full set of modules as separate files can add overhead for block sizing (both on disk and in memory, executables pad out each section to some block size), by requiring more load-time inter-module fixups I would be surprised if this showed up in any profile. Importing modules can already be slow no matter external stats (see programs like mercurial that, to win benchmarks with C-compiled counterparts, do lazy imports). As for the overhead at the border of blocks, you should be more worried with 800K of CJK codecs being loaded in your virtual memory (and not fully swapped out because of block sizing) which are totally useless for most applications. Anyway, we're picking nits here, but you have a point in being worried. If I ever write a PEP, I will produce numbers to show beyond any doubt that there is no performance difference. , and by not allowing the linker to perform some optimizations. It'd be worthwhile seeing if the DLL would speed up or shrink if whole program optimization was turned on. There is no way whole program optimization can produce any advantage as the modules are totally separated and they don't have direct calls that the compiler can exploit. -- Giovanni Bajo -- http://mail.python.org/mailman/listinfo/python-list

I suppose the only difference is that is uses 3, rather than 2, rules to simplify before starting tree-like search. Thanks for the nice problem and the nice post. The issue with my code was not due to the reduction algorithms used. In fact we used exactly the same set of rules, my Cell.solve was equivalent to your Clean1 method and my Cell.skim was equivalent to your Clean3 method (except that my algorithm was only doing for (o1, o2) in ((out1,out2),), but it did not make any difference in most cases). The real problem was due to an external loop inside my solveByBruteForce which was absolutely useless. I fixed that and now everything seems ok.

Actually what the OP wants is already a method of dict, it's called
setdefault(). It's not overloaded by [] because it's believed to be better to
be able to say I want auto-generation explicitally rather than implicitly: it
gives the user more power to control, and to enforce stricter rules.
class meh(dict):

a = meh()
a[foo][bar] = 2
a[foo][dup] = 3
print a[foo][bar]
2
print a
{'foo': {'dup': 3, 'bar': 2}}
So I advise using this class, and suggest the OP to try using setdefault()
explicitally to better understand Python's philosophy.
BTW: remember that setdefault() is written setdefault() but it's read

ANN: Leo 4.4b1 released
Leo 4.4 beta 1 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458package_id=29106 The code is stable; there are no known serious bugs. Some features are incomplete. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name, with tab completion. - Many new commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. You can use Leo without using a mouse. - Flexible key bindings and input modes. You can emulate the operation of Emacs, Vim, or any other editor. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Dozens of other new features and bug fixes since Leo 4.3.3.

ANN:NewEdit 3.2 Released
What's it?
It's an Editor based on wxPython. NewEdit uses Mixin and Plugin
technique as its architecture. Most of its classes can be extended via
mixin and plugin components, and finally become an integrity class at
creating the instance. So NewEdit is very dynamic. You can write the
new features in new files, and hardly need to modify the existing
code. And if you want to extend the existing classes, you could write
mixins and plugins, and this will be bound to the target class that I
call Slot Class. This technique will make the changes centralized
and easily managed.
What are its features?
* Cross platform
o based on wxPython, so it can run anywhere that wxPython
works, such as: Windows, Linux.
o Unicode support.
* Most features of wxStyledTextCtrl(Scintilla)
o Syntax highlighting, support Python, c/c++, html, plain
text, perl, ruby, css, javascript
o Folding
o Brace Matching
o ...
* Extended selection
o Extended word selection -- You can press
Ctrl+?MouseDoubleClick to select a word including '.'
o Matched selection -- Select text in quoted chars like:
(), [], {}, '', .
* Other editing extension
o Duplicating text -- Just like Vim Ctrl+V, Ctrl+P, and
more. You can duplicate above or below char, word, line
o Quoting text -- Add some quoted chars before and after
selected text, just as: , '', (), [], {}, and
o Text convertion and view -- python - html, reStructured
Text - html, textile - html, and you can output or view
o Utf-8 encoding auto detect
o Changing document encoding
oAuto backup
oLast session support -- It'll save all the filenames as
closed, and reopen the files as next started.
oSmart judge the indent char -- It'll auto guess the
indent char, and sets it.
oFinding in files
oBookmark support
* Python support
obuilt-in python interactive window based on ?PyShell,
support Unicode
oAuto completion
o Function syntax calltips
o Run, run with argument, stop python source
o Auto change current path
o Python class browser
* Code snippets
o You can manage your code snippets with categories, and
each category can have many items. Every item will represent a code
snippet. You can insert an item just by double-clicking on it. It even
supports importing and exporting.
* Simple project support
o Can create a special file _project, so every file and
folder under the folder which has the _project can be considered as a
whole project.
* Extension mechanism
o Script -- You can write easy script to manipulate the all
resource of NewEdit, just like: text conversion, etc.
o Plugin -- Customized function. More complex but more
powerful. Can easily merge with NewEdit, and can be managed via menu.
o Shell command -- Add often used shell commands, and execute them.
* Ftp support
o You can edit remote files through ftp. You can add,
rename, delete, upload, download file/directory.
* Multilanguage support
o Currently supports two languages: English and Chinese,
which can be auto-detected.
* Shipped plugins(must be configed as used them before)
o Document links -- Python documentation and wxPython documentation.
o Many plugins can be found at NewEdit wiki page.
* Shipped scripts
o Many scripts can be found at NewEdit wiki page.
* Wizard (New)
o You can make your own wizard template. The wizard can
input user data, combine with template, and output the result. And
wizard also support code framework created. This feature will help you
improving coding efficiency.
* Direcotry Browser(New)
o Browse multiple directories, and you can really add,
delete, rename directories and files. Double click will open the file
in Editor window.
* AutoComPlete(acp)(New)
o Suport user autocomplete file, it can help to input code
very helpful and functional. Just like EditPlus, but may be more
powerful.

Do I understand it correctly that actually the rule has to be refined as pertaining to the (so called) immutable types (like e.g. integers, tuples/strings) whereas lists and dictionaries are mutable types and the said scoping rule does not apply ? The rule has to do with modifying namespaces. Setting a variable to a value modifies the variable's binding in its namespace; it doesn't matter whether the variable references a mutable or immutable type: = $ python Python 2.4.1 (#1, May 27 2005, 18:02:40) [GCC 3.3.3 (cygwin special)] on cygwin Type help, copyright, credits or license for more information. a = 1 b = [1,2,3] def foo(): ... a = 9 ... def bar(): ... b = [7,8,9] ... foo() print a 1 bar() b [1, 2, 3] = Note that there is no error, but the binding affect each function's local namespace instead of the global one. However, modifying a mutable type, in this case a list, is not a namespace binding operation, i.e., it doesn't make the variable point to a different object. Since you only need to access a variable's contents to modify the object to which it refers, you can do this: = def blah(): ... b[2] = 6 ... blah() b [1, 2, 6] = It is easy to think that the scoping rules give you read-only behavior, but with mutable objects it just isn't correct.

Re: Decimal ROUND_HALF_EVEN Default
[LordLaraby] If 'bankers rounding' is HALF_ROUND_EVEN, what is HALF_ROUND_UP? Not banker's rounding ;-). Same answer if you had said ROUND_HALF_UP instead (which I assume you intended) -- most of these don't have cute names. I confess to never having heard the terms. ROUND_HALF_UP etc are symbolic constants in Python's `decimal` module; see the docs. I usually do: Y = int(X + 0.5) scaled to proper # of decimal places. Which type of rounding is this? If either. If you meant what you said, it's not rounding at all, because it's insane for negative inputs. For example, int(-2 + 0.5) = int(-1.5) = -1, and no _rounding_ method changes an exact integer (like -2) to a _different_ exact integer (like -1). If you were assuming X = 0.0, then int(X+0.5) coincides with ROUND_HALF_UP on that domain. For X 0.0, ROUND_HALF_UP works like int(X-0.5). -- http://mail.python.org/mailman/listinfo/python-list
Re: Sudoku solver: reduction + brute force
ago wrote: You can see my amended code in the link above. Thanks, I will look into it sometime. At the moment I'm at a library computer, which severely limits my Python options. Meanwhile I have been thinking about the sudoku problem, maybe it will prompt you, me or someone else to make some kind of other implementation which would resemble what I am thinking about now. Imagine a sudoku representation which is inside a 9x9x9 cube. The values in the cubes' cells are just 1 or 0. The height of a '1' is determined by the value in the original (flat) sudoku grid. There are 81 filled cells in the cube, just like in a sudoku solution. If one would look at the cube from a side it would always be the case that a filled cell at some depth inside the cube would block your line of vision wichever column one would be looking at. In a way a sudoku is a special case of a magic square, and a magic square can be transformed to this view, and this way it can be seen as the solution to the problem of making a cube not transparent by filling the minimum number of cells. Now such a cube can be mirrored in 48 ways and it would still be the same 'kind' of solution. Also it would be possible to swap horizontal layers at will and still have some kind of solution that is the 'same' in some way. One could also swap vertical layers iff (and only if) one would stay inside a 3-block group of layers. On the other hand it would be possible to swap complete 3-block groups of layers (if I'm still making sense) and maybe there are other symmetries that would leave the original solution somewhat intact. Suppose one would be able to generate all these possible symmetries and only use the 'smallest' representation of the original position, this 'hash code' would consist of just letting Python sort the possible 'same' cubes and selecting the smallest. It could be used to prevent us from computing the same cube twice since we could check if we already saw something with the same hash code. Now to the optimization part. If we find empty cells in the cube where there are only few positions in the same row, column, or depth available, we can limit the search space considerably because cutting off leaves early is most profitable. Maybe it would even pay off to consider complete layers and selecting possible fillable cells that have minimal fillable layers' sums. Sorry, I guess I'm getting a little bit pataforical here, expect my Python script any day now :-). It will be implemented as a sparse matrix based on sets of triplets (3-tuples) where for example tuple (0,0,0) will mean that the cell with x , y and z coordinate having value '0', is filled (virtually has a '1' inside, the 'unfilled' cells in the cube (the zeros) are not represented). I wonder if I still make sense, it's hard to stay programming Python without a computer to correct my thinking. Can someone write an implementation to check my ideas?

Re: ConfigParser: writes a list but reads a string?
Terry Carroll wrote:
It looks like ConfigParser will accept a list to be writing to the
*.ini file; but when reading it back in, it treats it as a string.
Example:
###
import ConfigParser
def whatzit(thingname, thing):
print thingname, value:, thing
print thingname, length:, len(thing)
print thingname, type(thing)
cfgfile = cfgtest.ini
config1 = ConfigParser.ConfigParser()
config1.add_section(test)
t1 = range(1,11)
config1.set(test, testlist, t1)
outfile=open(cfgfile,w)
config1.write(outfile)
outfile.close()
config2 = ConfigParser.ConfigParser()
config2.read(cfgfile)
t2 = config2.get(test,testlist)
whatzit(t1, t1)
whatzit(t2, t2)
###
Output is:
t1 value: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
t1 length: 10
t1 type 'list'
t2 value: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
t2 length: 31
t2 type 'str'
That is, t1 is a list of length 10, consisting of:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
and is written out; but t2 is read back in as a string
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
of length 31.
It took me a while to figure this out, since they looked identical in
print statements.
Is there a pythonic way to read in a list from a .INI file with
ConfigParser? Is this expected behavior for ConfigParser? I would
not expect this conversion; rather, an exception when trying to write
the list if the list is not supported.
To read lists from .INI files I use following:
listvalues=INI.get(section, option).split(',')
where INI is an instance of ConfigParser
There is the problem of if list items contain commas.

Hi! [EMAIL PROTECTED] wrote: I have some significantly extended syntax for Python that I need to create a reference implementation for. My new syntax includes new keywords, statements and objects that are sort of like classes but not really. The implementation is all possible using standard Python, but the implementation isn't the point of what I'm doing. Speed and having an extra step to run a program are not issues that I need to be concerned with. I'd like to create a preprocessor if possible, because it would probably be easier than implementing the changes in the interpreter. I could just drop in standard Python code that provides the functionality when I encounter a part of my extended syntax. Modifying the interpreter, on the other hand, sounds like it would be pretty nasty, even though I have experience in interpreter hacking already. So my question is: what's the easiest way to implement a preprocessor system in Python? I understand I could use the tokenize module, but that would still require a lot of manual parsing of the Python syntax. Is it possible to use any of the parser module facilities to accomplish this without them choking on the unknown syntax? Or, alternatively, would modifying the interpreter ultimately be easier? I cannot really say much about how easy it would be to just write a preprocessor. However, I think what you are trying to do could be done reasonably easy with the PyPy project: http://codespeak.net/pypy PyPy is an implementation of a Python interpreter written in Python. (Disclaimer: I am a PyPy developer). It has a quite flexible parser/bytecode compiler that could probably be tweaked to support your new syntax (especially if the new constructs can be mapped to standard python).

I'm attempting to read the HTML to find out with characters I need (e.g. 1st, 3rd and 6th char) then look up those values in the security phrase, but I'm getting stuck on the following function: code def getValue(page,delimEnd) : EndVar = page.find(delimEnd) thisVar = page[EndVar-1:EndVar] return thisVar /code unique code I'm using as a delimeter :/strong/td td class=producttableinnerborder/td td/td tdselect name=char1 /unique code I'm using as a delimeter the specific number I require proceeds the ':' at the start of the code. What I'm attemping to pass in is some multiline HTML(above) and pick up the proceeding character, but it seems to be reading from the end of the HTML instead! I've only been using this setup for a couple of days so it's probably something simple, anyone care to enlighten me? cheers, Jon -- http://mail.python.org/mailman/listinfo/python-list
Looking for standalone Python
Hello, I have a need to have python on intranet server for other users to create a common tool base for working community (SW).

chi-squared tests in python?
Hi, I'd like to be able to use the chi-squared test in my code.

Using CGI to interface with an XML-RPC server
Hi all, Assume I have a working XML-RPC server that runs persistently and correctly accepts remote calls, executes the relevant code and outputs the XML-RPC result. This is fine when using an XML-RPC client. However, I wish to provide a web user interface. I gather it is possible to use PHP as an XML-RPC client but I am unable to do so because of artificially imposed server constraints. All I am able to use is good the old CGI. Is it possible to create python CGI scripts that accept form data in the usual way, package them as an XML-RPC request, call the server, receive the response then format this response into valid HTML to be emitted to the client? Is this desirable (what I mean is... is there an easier way?). Is there a better way to use a web browser as what is essentially an XML-RPC client? FYI, I know that is seems like using XML-RPC in this case is pointless.. it isn't, some users do indeed use the server as intended. Cheers, -- http://mail.python.org/mailman/listinfo/python-list

It's kind of bizarre in Python to use as a mutation operator, but I guess you could do it. Sort of like 'cout hello world' in C++. -- http://mail.python.org/mailman/listinfo/python-list

Re: magical expanding hash
Exactly, as in C++/ruby streams. But notice the extra checks needed to see whether we want a new leaf which is an array or a number, or we create an intermediate hash level. Would the checks look the same in python? -- http://mail.python.org/mailman/listinfo/python-list

You could check what is being shifted and make a new leaf of the appropriate type. If you put a number there though, you wouldn't be able to then add more nodes beneath that number. -- http://mail.python.org/mailman/listinfo/python-list
Re: Testing complex new syntax
Carl Friedrich Bolz wrote: I cannot really say much about how easy it would be to just write a preprocessor. However, I think what you are trying to do could be done reasonably easy with the PyPy project: http://codespeak.net/pypy PyPy is an implementation of a Python interpreter written in Python. (Disclaimer: I am a PyPy developer). It has a quite flexible parser/bytecode compiler that could probably be tweaked to support your new syntax (especially if the new constructs can be mapped to standard python). It looks like the lack of thread support means I can't just use PyPy by itself, unfortunately. But the tokeniser, lexer, parser and AST builder could do what I need with modification, then I could walk the generated AST and produce standard Python code from that. How easy would it be to separate these parts out from the rest of PyPy? -- http://mail.python.org/mailman/listinfo/python-list
Re: Shrinky-dink Python (also, non-Unicode Python build is broken)
Larry Hastings: As for future development of Windows-specific Python features... doesn't that generally happen in modules, rather than the Python interpreter, these days? Either in Mark Hammond's pywin32 (what used to be called win32all), or perhaps done in Python using ctypes. There haven't been any changes to the three Windows-specific modules (msvcrt, winreg, and winsound) mentioned in any What's New in Python 2.x document, and 2.0 came out more than five years ago. It is in the built-in modules providing OS features that there should be more use of Unicode. Unicode system calls are more accurate and have fewer limitations than ANSI system calls. Examples are allowing Unicode in sys.argv and os.environ or for file paths where the ANSI versions are limited to less than 260 characters. Are you willing to monitor and fix new Py_USING_UNICODE issues or are you proposing just to produce a patch now and then expect contributors to maintain this feature?

Re: magical expanding hash
The point of this exercise is to compare how either ruby or python can implement perl's default behavior when dealing with hashes. Since these are bread and butter of scripting, having a MEH class handy can enable fast semantically equivalent translation. This can be beneficial for demonstrating feasibility of migrating to python. Instead of debating philosophical justifications, I rather wonder what's the most appropriate pythonic way to solve the problem as stated. -- http://mail.python.org/mailman/listinfo/python-list
Converting TIFF files to PDF and/or JPEG
Hey guys, As part of a college project I'm trying to write a script to convert TIFF images downloaded from the US patent office site, www.uspto.gov. The tiff images are encoded using CCITT Group 4 compression and appear to throw an error when i try to save them using the Image library: im.save(outfile, PDF) It looks like this odd compression format is not supported, or am i wrong? I know its a long shot but would anyone have a different solution? Sophie. -- http://mail.python.org/mailman/listinfo/python-list
