The // operator was added to the language for a reason. I'm surprised at how few Pythonistas are using it six years later.

Re: howto obtain directory where current (running) py-file is placed?
dmitrey wrote: Hi all, I guess this question was asked many times before, but I don't know keywords for web search. Thank you in advance, D. In the future, please ask your question in the body of your message (not just in the subject line). This question has no answer in general. There are some things like __file__ that may be good enough depending on your usage, but keep in mind in general that: 1. __file__ may be altered directly by the program and give an answer that has no past or current relationship to any filename for the file that contains the code currently being run. 2. Even if you make no changes, it can contain arbitrary results in not uncommon situations (e.g. in my local install, an interactive python session--or one from a here-document in the shell--lists ~/.pythonrc or stdin in __file__, even though in neither case was I running my .pythonrc or a file named stdin 3. Without that, any file may have 0, 1, or many names; those names may differ now from what they were when the file was first accessed. So __file__ may refer to an unlinked name (even in the case where at least one name that existed when you first executed the file is still valid), or may even e the name of another, different file that was created (or linked/renamed) after you started running things. Depending on your needs, those factors may or may not matter. They're certainly worth being aware of, and for some applications they may have massive security implications. -- http://mail.python.org/mailman/listinfo/python-list
Re: Where can I suggest an enchantment for Python Zip lib?
Hi Larry! durumdara wrote: You can easily find out roughly how many bytes are in your .ZIP archive by using following: zipbytes=Zobj.fp.tell() The main problem is not this. I want to write a backup software, and I want to: - see the progress in the processing of the actual file - abort the progress if I need it If I compress small files, I don't have problems. But with larger files (10-20 MB) I get problems, because the zipfile's method is uninterruptable. Only one way I have to control this: if I modify the ZipFile module. dd On Jun 7, 8:26 pm, Larry Bates [EMAIL PROTECTED] wrote: Where Zobj is your zipfile instance. You don't need a callback. Problem is ill defined for a better solution. You don't know how much the next file will compress. It may compress a lot, not at all or in some situations actually grow. So it is difficult (impossible?) to know how many bytes are remaining. I have a rough calculation where I limit the files to 2Gb, but you must set aside some space for the table of contents that gets added at the end (whose size you don't actually know either). So I use: maxzipbytesupperlimit=int((1L31)-(8*(120))) That is 2Gb-8Mb maximum TOC limit of a zip file. I look at zipbytes add the uncompressed size of the next file, if it exceeds maxzipbytesupperlimit, I close the file and move to the next zip archive. If it is smaller, I add the file to the archive. Hope this helps. -Larry -- http://mail.python.org/mailman/listinfo/python-list

Minimize Bandwidth
Hello Chaps, I have a python application that hits a web service on a regular basis to post a string of CSV log data and I'm looking to minimize the amount of bandwidth that the application uses to send the log data. Is there any way to encode the string into base64 or something, that I can then post and decode at the other end? Is that likely to save me bandwidth perhaps? I don't really know much about this encoding stuff, but the smaller I can compress the string the better. Thanks, Rob -- http://mail.python.org/mailman/listinfo/python-list

True. But there is another issue attached to the one i wrote.
When i know how much this occurs, i know the amount of pages in the
file. After that i would like to be able to extract a given amount of
data:
file x contains 20 0C. then for example i would like to extract from
instance 5 to instance 12 from the file.
The reason why i want to do this: The 0C stands for a pagebreak in PCL
language. This way i would be absle to extract a certain amount of
pages from the file.

If that is true, then we should be concerned; if he is just paranoid, then we should empathise with his sickness. What we should not do is to invite censorshipthat just could be implicitly joining in the putative Conspiracy. Let's look at Mike's potential options (and the alleged responses he has received): 1. Complain to the Police: (their alleged response Don't be silly, Sir; Mike's rationale They are part of the Conspiracy) I don't think the police as an organisation are part of it. They're certainly not the source. The officer I spoke to at Easter clearly didn't know anything about it. And that was at my local police station in London - if anyone in the police knew you would think the people at your local cop shop would. A couple of years ago I had to go into the station after a motoring infraction, the guy I spoke to then said something about brain like a computer sir which my suspicions latched on to - (I'm alleged to be a programmer as some people reading this know) - but as per the usual can';t prove nuthin and you ask yourself if you're just being stupid suspecting on the basis of a straw 2. Complain to a Member of Parliament (Mike's rationale: Can't because they are part of the Conspiracy) I could do that actually. But he would probably tell me to go see the police, for which see above. 3. Make it visible through the UK Press. (Mike's rationale: Can't because they are part of the Conspiracy) They are actually. There's a difference though in the way journalists react to this stuff when they're got to by the security service. This is completely giving the game away, but the trouble originally started with my reading into stuff that was being written by Times columnists, in particular our antagonistic friend Mr Levin. But you see that some journalists are taking part in the conspiracy and others are only doing it because their puppet masters have been feeding them information which they can't allow themselves to ignore. The security services have their hooks into the UK media, this case shows that very explicitly. You also see how things get gradualkly wqorse with a particular journalist; a couple of weeks ago Peter Tory in the Express was writing about nerds seeking their revenge on him through the Net, guess what that was about. 4. Complain to the UK Security Services. (Mike's rationale: Can't because they ARE the Cnspiracy) Quis custodiet ipsos custodes? If the fascist Gestapo bastards plot to see you dead then who's going to deal with it? Not the security services, that's for sure. 5. Make it visible through Internet: (Mike has done this suvccessfully; but any gainsayers are part of the Conspiracy. I don;t think you';re part of the consipracy if you refuse to believe or email the postmaster. Those

MI5 Persecution: Goldfish and Piranha 29/9/95 (5104)
I just thought I'd let you know what I've been reading into the Crusader spam. I don't want to post this to usenet because somebody might try to tie that in to my posts in some way (someone already has, in uk.misc). First of all, I'd like to ask you to believe that my phone line in my apartment is bugged, and has been for many months. I have moved a couple of times this year, but they have faithfully been on my trail. Anyway, let's suppose my phone line is bugged. Now, when I talk to my internet service provider, it's over a SLIP (now PPP) connection. So if you wanted to bug what was said, either you'd listen in over the line and have to decode the transmission, or you could go to the service provider (more difficult) and ask them to decode a particular user's connection. OK, so now they're listening to everything I do over my SLIP/PPP connection. A couple of months ago I was messing around with faking articles through nntp servers and through anonymous remailers. I chose a nice inconspicuous newsgroup for my little tests, something no-one would ever notice. Guess which newsgroup I chose??? Yes, _FISH_!!! or rec.aquaria to be precise And guess what articles I tried to post? Goldfish, Koi carp and, you'll never guess... PIRANHA!!! The goldfish article and the Koi went through, but the piranha didn';t appear. by now you probably think this is too silly for words. But if you look in the papers a few eeks ago you will find John Major, Tonny Blair and Paddy Ashdown sharing a private joke about Major's sunburnt goldfish. We haven't had anything about Koi yet (they must be too dull ). Now, sent by someone who clearly knew what they were doing (they chose an Italian backbone site for their launch point) we have many thousands of messages to people all over the globe. All about piranha, and with the punchline that gives you something to think about, doesn't it? The way it works is that they're trying to kill two birds with one stone again. I don't knoiw why they should be against these national alliance people, but my interpretation is that they simultaneously try to discredit them, and stem the flow of Corley articles. = In article [EMAIL PROTECTED], Mike Corley [EMAIL PROTECTED] wrote: John J Smith ([EMAIL PROTECTED]) wrote: : b) we do know who you are.

But if I named people, then (a) they would object violently to being included in this shenanigans, and (b) I would be revealing my identity which would be bad for my personal life and my work life.

Revealing identity? :To who? And why would this be bad for any part of your life when you :already have a less than respectful reputation here? I'll just enumerate one or two things that I can still remember. Sometime around August/Sept 1992 I was living in a house in Oxford, and coming out of the house was physically attacked by someone - not punched, just grabbed by the coat, with some verbals thrown in for good measure. That was something the people at work shouldn't have known about... but soon after a couple of people were talking right in front of me about, yeah, I heard he was attacked. Again, one I went for a walk in some woods outside Oxford. The next day, at work, someone said you know he went to the forest yesterday. I don't want to put details on usenet of what happened because to do so would be to risk it happening again. If you put ideas in peoples' heads then you can find them reflecting back at you, and I don't want that. Also I can't remember that much from three years ago. From november 1992 I started taking major tranquilizers and just blotted the whole thing from my mind. This is a feature time and time again, that the security services (presumed) get at you by manipulating other people around you to get at you. If you have their contacts, manpower, resources and technology then you can do that sort of thing. :But why? Are you a threat? They pretend they have to get at me.

Re: How Can I Increase the Speed of a Large Number of Date Conversions
vdicarlo [EMAIL PROTECTED] writes: I am a programming amateur and a Python newbie who needs to convert about 100,000,000 strings of the form 1999-12-30 into ordinal dates for sorting, comparison, and calculations. Though my script does a ton of heavy calculational lifting (for which numpy and psyco are a blessing) besides converting dates, it still seems to like to linger in the datetime and time libraries. (Maybe there's a hot module in there with a cute little function and an impressive set of attributes.) Anyway, others in this group have said that the date and time libraries are a little on the slow side but, even if that's true, I'm thinking that the best code I could come up with to do the conversion looks so clunky that I'm probably running around the block three times just to go next door. Maybe someone can suggest a faster, and perhaps simpler, way. Here's my code, in which I've used a sample date string instead of its variable name for the sake of clarity. Please don't laugh loud enough for me to hear you in Davis, California. dateTuple = time.strptime(2005-12-19, '%Y-%m-%d') dateTuple = dateTuple[:3] date = datetime.date(dateTuple[0], dateTuple[1], dateTuple[2]) ratingDateOrd = date.toordinal() P.S. Why is an amateur newbie trying to convert 100,000,000 date strings into ordinal dates? To win try to win a million dollars, of course! In case you haven't seen it, the contest is at www.netflixprize.com. There are currently only about 23,648 contestants on 19,164 teams from 151 different countries competing, so I figure my chances are pretty good. ;-) I can't help noticing that dates in '-mm-dd' format are already sortable as strings. '1999-12-30' '1999-12-29' True depending on the pattern of access the slightly slower compare speed _might_ compensate for the conversion speed. Worth a try.

At university there were people who quite overtly hated me and would have wished something nasty to happen to me. Because of where I went making the wrong sort of enemies is pretty deadly.

One was expressing doubts to the other (let's call the first one Simon, shall we? and the second one Phil?) about whether what was going on was right. Phil's answer was that if Private Eye was doing it then it must be ok, they're usually right. A few days later, again near work, there were some students laughing in the street, Were you COMING BACK later? But I thought you said you were COMING BACK ha ha ha? Play on words, you see. Not very nice, either. I had start medication soon afterwards. Clever people, these chaps who think up PE titles. Just slightly lacking in any sense of morality. ##: How did they do this?

I have this simple Pyrex module: cdef class Foo: cdef public char attr def __init__(self): self.attr = 0 class Bar(Foo): def __init__(self): Foo.__init__(self) self.attr2 = None def mod(self): self.attr = c'B' f = Bar() f.mod() When I run Python and import it an exception is raised: % python Python 2.4.2 (#1, Feb 23 2006, 12:48:31) [GCC 3.4.1] on sunos5 Type help, copyright, credits or license for more information. import badattr Traceback (most recent call last): File stdin, line 1, in ?

Is this a Pyrex bug or am I not allowed to modify cdef'd attributes in subclasses? (Note that I want Bar visible outside the module, hence no cdef.)

True. But there is another issue attached to the one i wrote.
When i know how much this occurs, i know the amount of pages in the
file. After that i would like to be able to extract a given amount of
data:
file x contains 20 0C. then for example i would like to extract from
instance 5 to instance 12 from the file.
The reason why i want to do this: The 0C stands for a pagebreak in PCL
language. This way i would be absle to extract a certain amount of
pages from the file.
And? Finding the respective indices by using
last_needle_position = 0
positions = []
while last_needle_position != -1:
last_needle_position = contents.find(needle, last_needle_position+1)
if last_needle_position != -1:
positions.append(last_needle_position)
will find all the pagepbreaks. then just slice contents appropriatly.

Working with fixed format text db's
Many of the file formats I have to work with are so-called
fixed-format records, where every line in the file is a record,
and every field in a record takes up a specific amount of space.
For example, one of my older Python programs contains the
following to create a fixed-format text record for a batch of new
students:
new = file(new.dat, w)
if not new:
print Error. Could not open file new.dat for writing.
raw_input(Press Return To Exit.)
sys.exit(1)
for s in freshmen:
new.write(s.ssn.ljust(9))
new.write(s.id.ljust(10))
new.write(s.last[:16].ljust(16))
new.write(s.first[:11].ljust(11))
new.write(' '.ljust(10)) # Phone Number
new.write(' '.ljust(1254)) # Empty 'filler' space.
new.write('2813 ')
new.write(s.major.ljust(5))
# Etc...
Luckily, the output format has not changed yet, so issues with
maintaining the above haven't arisen.
However, I'd like something better.
Is there already a good module for working with fixed format
records available? I couldn't find one.
If not, please suggest how I might improve the above code.

If you want to tease out the magic code from wxProcess that does non-blocking reads on win32 then I'd be happy to integrate that into the current development branch of Pexpect. Windows has a really strange idea of non-blocking IO - it uses something called overlapped io. You or in the FILE_FLAG_OVERLAPPED flag when you create the file/pipe. You then pass in overlap buffers for reading writing. I implemented this for serial ports in C a while ago. If you look at the code in pyserial (in serialwin32.py) you'll see a very similar implementation of non blocking IO. I assume that the same things will work for pipes, but I've only direct experience with serial ports! I'm sure this is feasible without any C extensions -- it might require some ctypes hacking. pyserial uses win32file and win32event I know Windows has pretty decent async IO, but I don't know what they have as an equivalent for a pty. Maybe it isn't necessary. A pty is only necessary on UNIX because the standard c library, stdio, behaves differently when it's talking to a plain pipe versus a terminal -- it switches buffering between block and line oriented buffer. You don't want block buffering on interactive applications. Pty's probably aren't needed on Windows. BTW I'd love to see pexpect working on windows and also in the standard library.

The problem surely is that when you want to change the format you have to do so in all files (and what about the backups then?) and all programs simultaneously.

However, I'd like something better. What precisely do you want to achieve? I was hoping for a module that provides a way for me to specify a fixed file format, along with some sort of interface for writing and reading files that are in said format. It is not actually *hard* to do this with ad-hoc code, but then the program is indecipherable without a hardcopy of the spec in hand. And also, as you say, if the spec ever does change, the hand-written batch of ljust, rjust and slice will be somewhat of a pain to reconfigure. But biggest weakness, to me, is that the specification is not in the code, or read and used by the code, and I think it should be. If nothing exists already I guess I'll roll my own. But I'd like to be lazier, and virtually all published modules are better than what I'll write for myself. ;) The underlying problem, of course, is the archaic flat-file format with fixed-width data fields. Even the Department of Education has moved on to XML for most of it's data files, which are much simpler for me to parse. -- Neil Cerutti -- http://mail.python.org/mailman/listinfo/python-list

Since divmod() returns a tuple, you need to unpack it. For example: q, r = divmod(10, 3) print q 3 print r 1 If you want to store all the remainders as you go, maybe you could build up a list of remainders by starting with an empty list and append() the values to the list as you go through the loop. -- Jerry -- http://mail.python.org/mailman/listinfo/python-list

Re: Verify server certificate in HTTPS transaction
I struggled with that months ago. The SSL library that ships with Python is primitive, but M2Crypto can do that. M2Crypto will actually verify the certificate chain. The documentation is weak, it's hard to build, and there are bugs, but it's the best Python has right now. John Nagle Hamish Moffatt wrote: Hi, I'm fetching some files over HTTPS from Python and I want to verify the server certificate. (Not just the name etc provided in certificate.) How can I get access to this information? urllib2 doesn't seem to provide it. Even a raw SSL socket only appears to provide access to the CN, OU etc in string form (not the raw certificate). I tried pycurl, which allows you to setopt(pycurl.SSL_VERIFYPEER) and VERIFYHOST, but the getinfo(pycurl.SSL_VERIFYRESULT) call always returns 0. Perhaps it's unimplememented? I couldn't get the M2Crypto API documentation to generate; perhaps it allows it. TLS Lite on to of M2Crypto? Something else again?
