a few fixed symbolic values. (This is less functionality than an enum,
since there are no *numbers* associated with the values). I do want
the thing to fiercely object to assignments or comparisons with

.if c.status 'done': something # Mode arg strings define ordering

somewhat sneaky (I think) exporting of a property-factory instead of a

What's wrong with :

That's not what translate does with the badchars, which is a set of
characters, each and all of whose instances in the source string
will be deleted from the source string. Something like
for c in badchars:
s = s.replace(c,'')
It seems obvious to replace a char ( to me anyway ) with a blank
string, rather than to 'translate' it to None.
I am sure you have a reason what am I missing ?
M.E.Farmer
The first argument is normally a 256-character string that serves as a table
for converting source characters to destination, so s.translate(table, bad)
does something like
s = ''.join([table[ord(c)] for c in s if c not in bad]
help(str.translate)
Help on method_descriptor:
translate(...)
S.translate(table [,deletechars]) - string
Return a copy of the string S, where all characters occurring
in the optional argument deletechars are removed, and the
remaining characters have been mapped through the given
translation table, which must be a string of length 256.
So just to delete, you wind up constructinf a table argument that is just 1:1
as in
'abcde'.translate(''.join([chr(i) for i in xrange(256)]), 'tbd')
'ace'
and the answer to the question, What translation does such a table do? is
None ;-)

Yes, indeed. I never use those, and would probably do something akin to what you are suggesting rather than doing so. I simply enjoy the no-hassle simplicity of fileinput.input() rather than worrying about whether my data will be piped in, or in file(s) specified on the command line. -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list
Re: interactive web graphics
I'm surprised that Trolltech is allowing Microsoft to get their product for free. If the free version is used, it's license is GPL. So for commercial apps, you still need a license (for linux as well) I have played with Qt3 somewhat; not sure how their widgetry compares with GTK+, as far as looks are concerned, but much prefer C++. Disappointingly, the openGL module for QT failed to work when I ran the examples. I hear VTK is nice. Just checked Google and, sure enough, there's a pyVTK. Dunno why that happened - Qt certainly has gl support. -- Regards, Diez B. Roggisch -- http://mail.python.org/mailman/listinfo/python-list

Quoth David Isaac [EMAIL PROTECTED]: | I'm looking for the Python equivalent of the perl script and module | described at | http://comments.gmane.org/gmane.mail.imap.uw.c-client/707 | | Any hope? Sure, should be doable, if for some reason you can't just use that. I personally wouldn't do it exactly that way, rather I would just read the file directly. At first you said you were only interested in fixing the header. This one operates on the rest of the file, and I guess I will assume that's what you really want. MBX structure is just a one line message header before each message, with a message size value among other things. Readers of this format will add that size value to the current file offset and expect another header line at that point. When the data there isn't a valid header line, they die. One does not need the c-client library to do this, but more to the point it isn't what you want to do, with a damaged file. Just read the file from one end to the other and find everything that looks like a header line, and then rewrite the file with adjusted header lines required so that - they are in ascending order by ID number - they have correct sizes.

It complained arrays can only be bound to PL/SQL statements I tried looking at the source code but couldn't figure out how to do this. In no small part due to my nearly complete lack of experience with Oracle or for that matter SQL databases.

That seems unlikely. For example,
os.path.isdir(r'D:\My Documents')
True
Can you show the code?
Alternatively you might try os.walk() which is a bit easier to use than os.path.walk() and it gives
you separate lists for files and directories:
import os
for dirpath, dirnames, filenames in os.walk('f:/tutor'):
... for file in filenames:
... print os.path.join(dirpath, file)
...
f:/tutor\AllTheSame.py
f:/tutor\AppendTimes.bmp
ecc...
Or even easier, use jorendorff's path module which has a walkfiles() method that iterates over files
directly and gives you path objects to work with:
import path
for file in path.path('f:/tutor').walkfiles():
... print file
...
f:/tutor\AllTheSame.py
f:/tutor\AppendTimes.bmp

Re: [newbie] Embedding Flash OCX object
The Great 'Exeem' uttered these words on 4/30/2005 11:37 AM: Kartic, Thanks for your reply, I already use the wxPython to embbed my flash animation ### from wxPython.lib.activexwrapper import MakeActiveXClass ActiveXWrapper = MakeActiveXClass(flashActiveXLib.ShockwaveFlash, eventClass=None, eventObj=self) Flash = ActiveXWrapper( self, -1, style=wxSUNKEN_BORDER) It work fine and i can control my flash animation from Python without problem.. But the Wrapper need the flash.ock to be installed on the user system in order to work, and i would like to make an executable application that include the flash.ocx or load it on startup for users who doesn't have the flash player installed. I would like also to be able to load a flash animation from memory and not to load it from external file. Don't know if you understand me.. Take a look at http://www.flashplayercontrol.com/ .. I'd like such a solution for Python, don't know if i can use that dll from Python or make a module myself.. Anyway, thank a lot for your interest Dan Dan, Ah! I see what you are trying to do. While I don't have a working piece of code to share with you, I can give you a few ideas that you could consider: 1. Supply the Macromedia OCX with your app. Try to use the wxActivex class and if that fails, register your copy of the OCX. You can do this either using a batch file invoking regsvr32 or use Win32 to register. The flip side: The flash will be loaded from a file rather than memory. 2. Wrap the flashplayercontrol.com's DLL in an Activex control using VB and distribute your OCX. And then use wxActivex to access your OCX. 3. Use SWIG to generate Python bindings for the DLL. I have never done this and I am sure some of the more erudite members of the newsgroup can shed some light. 4. Call the supplied DLL using Ctypes. In this case, you can convert the example under the Features link of that site in DLL calls using Ctypes. Question: How will that integrate with wx? Hope that helped a bit.

Re: Ron Grossi: God is not a man
Larry Bates, I truly appreciate the dignified tone of your response. Kindly allow me to respond. IN SPITE OF THE BIBLE, NOT BECAUSE OF IT? = First I do apologize for the earlier long discourse; I am afraid this might be just as long. There is much to discuss and I try to be through. Having said that, and to respond to your point, please be informed that I did not take any scripture out of context so as to reach a conclusion of my own. If you'd be kind enough to point out one incident I will promptly apologize and will take it back. With that said, I hope you are fair enough to agree that if someone makes a claim that then the same person should back that claim up with proof. That out of context claim you make, brother, is made without proof. Please tell us how Christ the man (Acts 2: 22), and the son of man (Luke 9: 58) are not part of the Christian textual sources or how they were taken out of context. How is that when it is proclaimed in the Law attributed to Almighty God that God is not a man ... neither the son of man (Numbers 23: 19) that this part of the Law (given Acts 2:22, and Luke 9: 58) is not applicable to Christ PBBUH or any other man and son of man from the beginning of time until the end of time. You see, Larry, if someone were to write an essay and post satellite images in support of the fact that earth is spherical, anyone defending the false notion that the earth is flat can simply counter: you are taking things out of context. But these words will not do, as any fair person can confirm. Without proof, a claim is what it is: just a claim. The burden of proof is on the one who makes the point to prove it, not on the other party to refute what was not proven. In my case, proof was offered in defence of my assertions from what Christian authorities themselves regard as Christian textual sources of divine origin. Does that not carry enough weight for you so as to be convinced? If people will read in their textual sources that God is not a man ... neither the son of man and *yet* go on to believe in- and even argue the exact opposite of that- just because they have an opinion, then what is the Bible for then? If people are going to believe that Christ the man (Acts 2:22), and the son of man (Luke 9: 58) is Almighty God Himself in spite of Numbers (among others), then what is the point of these people having textual sources for their beliefs? Wouldn't it be better if these people got together, sat down, and wrote a novel and made a religion out of it? This is what the Church of Scientology did. Perhaps then that novel would agree with their man-made beliefs, namely that God is a man and is the son of man in spite of (Numbers 23: 19)? That God will dwell on the earth in spite of (1 Kings 8: 27)? That there are other 'Gods' with God and that there is now someone like unto God in spite of (Isaiah 46:9)? And so on and so forth? After all, let's face it, Larry, the novel is there inside your (plural) head, and it is from which you are all reading to us that Christ PBBUH the man and the son of man is actually God; but whether you realize it or not, you are doing so in spite of the word of God as found in the Bible, not because of it. I truly don't know how to make a mention of this and not appear like I wish to offend you, which is truly not my intention, but I must inform you anyway: does the word anti ring any bells? PLURAL GOD? === Do you believe that God is one or not? Was it not Christ PBBUH himself who said that the Lord our God is one Lord (as opposed to a tri-une Lord) or was he not? Is there a single explicit mention of the word Trinity in the entire encyclopaedia of books called the Bible? Just one? There is none, can you believe it? THE DONKEY RIDE --- Please read from the New Testament: ... and they sat him thereon. (The Donkey) (Matthew 21:7) ... and he sat upon him. (The Donkey) (Mark 11:7) ... and they set Jesus thereon. (The Donkey) (Luke 19:35) ... Jesus ... sat thereon: (The Donkey) (John 12:14) In Is The Bible God's Word[1], Ahmed Deedat writes: Could God Almighty have been the author of this incongruous situation - going out of His Way to see that all the Gospel writers did not miss their footing recording of His son's donkey-ride into the Holy City - and yet inspiring them to blackout the news about His son's heavenly flight on the wings of angels? I note the exact same amazing situation here. Why is it so important to have all the Gospels mention the donkey incident but not have one single explicit remark anywhere about what effectively will decide the eternal fate (repeat: eternal fate) of many: the alleged trinity? Astonishing, no? WHY NOT A PENTINITY?

Unless of course you consider the contents of the Bible from which I quote as such. Seeing that you claimed that there was no truth in my post, I was hoping to read proof in support of your claim. To my disappointment, there was none. Just a reference to the word Allah made, alas, in haste. I wish that you'd considered your words before you rushed to post.

Did you know that their Arabic Bibles (together with their Arab Jews brethren) have the word Allah exactly where the word God appears in your English Bible? Furthermore, did you know that in Malta, made up of a population of staunch Catholics, people use the word Allah for God in their own language?

Tripoli: a Python-based triplespace implementation
I have been working on a Python implementation of a modified Tuple Space (cf Linda, JavaSpaces) that contains only 3-tuples (triples), and that has operators for copying and moving graphs of triples as well as sets matching a given pattern. It's called Tripoli, and the code for it can be found here: http://www.codepoetics.com/code/tripoli More explanation of what it is and what it's meant to do can be found in these three blog posts: http://codepoetics.com/poetix/index.php?p=110 http://codepoetics.com/poetix/index.php?p=111 http://codepoetics.com/poetix/index.php?p=113 (this post includes some sample code, that may clarify intended usage somewhat) At present, a simple XML-RPC server is used to expose a manifold - a collection of triple spaces - to multiple clients. I will be supplementing this with something beefier, and more REST-ful, in due course - probably based on Twisted. This is code in the very earliest stages of testing and development - I would very much welcome comments and suggestions from any intrepid persons who fancy having a play around with it.

For another, I dislike the idea of a module sitting unupdate for long periods of time (decades, say). Updating Python provides a good excuse to update all the python modules, etc. Now, it would be nice if Python provided an easy way to do the update. The FreeBSD packaging system happens to provide a way to automate this process, but it's still not exactly easy. So my alternative solution is that PyPI have a mechanism to maintain what had been installed in the site-package directory and to download the libraries and install into the new site-package directory... PyPI is the wrong place to maintain a record of installed software. Distutils is the software that does the installing (ok, on most modules, anyway), and is the software that should record what packages are installed. Neither distutils nor PyPI has a download functionality. For that matter, PyPI doesn't have a hard requirement on listing where a module comes from. I'd say distutils is the software that should provide it, so I can say: python setup.py install --depends and get all the dependencies. But that's not at all clear.

To my disappointment, there was none. Just a reference to the word Allah made, alas, in haste. I wish that you'd considered your words before you rushed to post. I say that for the following reason: did you know that there are around 26 million Christian Arabs living in the world today? Did you know that their Arabic Bibles (together with their Arab Jews brethren) have the word Allah exactly where the word God appears in your English Bible? Furthermore, did you know that in Malta, made up of a population of staunch Catholics, people use the word Allah for God in their own language?

ANN: pynetwork 2.25
Pynetwork is a graph library, my first SourceForge project: http://sourceforge.net/projects/pynetwork/ It included tests, some demo, some premilinary docs, and some images. You can see some screenshoots on the SourceForge page for them. I know about 5-6 other graph libraries for Python, one even in C++ (Boost). This library is quite fast, and it can be imported with: import graph I've designed it inspired by the sets.py standard module, but here there isn't a frozengraph because I think it's not much useful. Inside the docstrings there are many definitions that can be used as a graph theory glossary. Surely there are some things to be fixed, I'm still improving it. Beside the demos, I can add a kind of tutorial, and few more classical algorithms. Comments, suggestions, bug fixes, collaborations, etc., are surely appreciated. I don't know if Python will ever have a graph data structure in the collections standard library, but I've tried by best so far :-) Bear hugs, Bearophile (Remove HUGS from my address if you want to email me) -- http://mail.python.org/mailman/listinfo/python-list

That's nice. Well I agree with you, if the OP is concerned about embedded
CRs, LFs and ^Zs in his data (and he is using Windows in the latter case),
then he *definitely* shouldn't use fileinput.
And if the OP is naive enough not to be concerned, then it's OK, is
it?
It simply isn't a problem in some real-world problem domains. And if there
are control characters the OP didn't expect in the input, and csv loads it
without complaint, I would say that he is likely to have other problems once
he's processing it.
Presuming for the moment that the reason for csv not complaining is
that the data meets the csv non-spec and that the csv module is
checking that: then at least he's got his data in the structural
format he's expecting; if he doesn't do any/enough validation on the
data, we can't save him from that.
What if the input is UTF-16? Your solution won't work for that. And there
are certainly UTF-16 CSV files out in the wild.
The csv module docs do say that Unicode is not supported.
This does appear to work, however, at least for data that could in
fact be encoded as ASCII:
import codecs
j = codecs.open('utf16junk.txt', 'rb', 'utf-16')
rdr = csv.reader(j, delimiter='\t')
rows = list(rdr)
The usual trick to smuggle righteous data past the heathen (recode as
UTF-8, cross the border, decode) should work. However the OP's data is
coming from an MF, not from Excel save as Unicode text (which
produces a tab-delimited .txt file -- how do you get a UTF-16 CSV
file?) and if it's not in ASCII it may have a bit more chance of being
in EBCDIC than UTF-16 -- unless MFs have come a long way since I last
had anything to do with them :-)
In any case, my solution was a sketch, and stated to be such. We
don't know, and I suspect the OP doesn't know, exactly (1) what
encoding is being used (2) what the rules are about quoting the
delimiter, and quoting the quote character. It's very possible even if
it's encoded in ASCII and the delimiter is a comma that the quoting
system being used is not the expected Excel-like method but something
else and hence the csv module can't be used.
I think at some point you have to decide that certain kinds of data
are not sensible input to your program, and that the extra hassle in
programming around them is not worth the benefit.
I prefer to decide at a very early point what is sensible input to a
program, and then try to ensure that nonsensible input neither goes
unnoticed nor crashes with an unhelpful message.
There is also an on principle element to it as well -- with
fileinput one has to use the awkish methods like filelineno() and
nextfile(); strikes me as a tricksy and inverted way of doing things.
Yes, indeed. I never use those, and would probably do something akin to what
you are suggesting rather than doing so. I simply enjoy the no-hassle
simplicity of fileinput.input() rather than worrying about whether my data
will be piped in, or in file(s) specified on the command line.
Good, now we're singing from the same hymnbook :-)

I can't guarantee there is no app to help with this, but if it does exist, it either costs a lot of money, or will be almost impossible to use for what you want (boiling two voice samples down to a speaker-independent single similarity number... the mind boggles at the possible number of ways of defining that).

Summary: Embedded python thread crashes
Initial Comment:
The following code crashes about 1/3 of the times.
My platform is Python 2.4.1 on WXP (I tried the release
version from the msi and the debug version built by me).
I can reproduce the same behavior on another wxp
system, under python 2.4.
The crash happens (in the python thread) while the main
thread is in Py_Finalize.
I traced the crash to _Py_ForgetReference(op) in
object.c at line 1847, where I have op-_ob_prev == NULL.
The open file seems to be the issue, since if I remove
all the references to the file I cannot get the program
to crash.

[ python-Bugs-1193180 ] Strange os.path.exists() results with invalid chars
Bugs item #1193180, was opened at 2005-04-30 23:13 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1193180group_id=5470 Category: Windows Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Daniele Varrazzo (dvarrazzo) Assigned to: Nobody/Anonymous (nobody) Summary: Strange os.path.exists() results with invalid chars Initial Comment: Hi, when there are invalid chars in a filename, os.path.exists () behaves oddly, returning True. The bug appears on win32 system, not on unix ones. Thus is probably related to some weird windows api call and doesn't maybe worth fixing. Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)] on win32 Type help, copyright, credits or license for more information. import os f = file(a_b, w) f.close() os.listdir(.) ['a_b'] os.path.exists(ab) True os.path.exists(ab) True And, even more strange... os.path.exists(a) True os.path.exists(a) False Better answers would have been: * False * raise ValueError -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1193180group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Currently, it checks for equality. For example, this is necessary in order to use a Python built for Mac OS X 10.3 but build an extension with features specific to Mac OS X 10.4. Backport candidate to 2.4, patches attached. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=105470aid=1193190group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
