"EdWhyatt" <[EMAIL PROTECTED]> wrote: > >Ok, totally unrelated, and on that subject, I will make sure I always >have a recipient in the To: field. - hey it works if I do that anyway! OK, I'm a bit concerned that the answer to the original question has been lost. The difference between the SMTP envelope and the message content is an important one, and that's the key point here. If this is obvious to everyone involved, I apologize. The actual content of an e-mail message, including the message headers, has absolute nothing to do with the delivery of the message. That's all just a convention that we have developed to allow messages to be read by humans. All of the To:, Cc:, and Bcc: headers are there for you, the human (well, and your helper, the e-mail reader). SMTP doesn't care one whit about them. The smtplib.sendmail method has three parameters: sender, recipient list, and content. SMTP could not care less about the content. You can skip ALL of the headers (as long as you leave a blank line), and it will be delivered just fine. It won't be RFC 822 compliant, but SMTP doesn't care. SMTP is RFC 821. Your message will get delivered, although the recipients e-mail reader might croak on it. SMTP cares about the sender and the recipient list. Going off the deep end, consider this Python snippet: msg = """\ To: [EMAIL PROTECTED] Subject: This is the RFC-822 part Hello, mom!""" s = smtplib.SMTP('localhost') s.sendmail( "[EMAIL PROTECTED]", ["[EMAIL PROTECTED]","[EMAIL PROTECTED]"], msg ) Note that the To: address is not listed in the sendmail parameters. Now, here is a "simulated" SMTP script for this message: MAIL FROM: <[EMAIL PROTECTED]> RCPT TO: <[EMAIL PROTECTED]> RCPT TO: <[EMAIL PROTECTED]> DATA To: [EMAIL PROTECTED] Subject: This is the RFC-822 part Hello, mom! . Those first four commands are SMTP, generated from the first two parameters to sendmail, and those are the ONLY things that determine where this message will be delivered. The are called the "envelope". Note that the actual recipients' names do not appear in the message body AT ALL. At the other end, Mr. One at Foo, Inc., might be surprised to receive a message that does not appear to have been addressed to him, but SMTP doesn't care. So, the way a BCC works is that the address goes into the envelope (in the to_addrs list), but not in the message body. -- - Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list

No, that's not the reason. The reason is that this includes a redirect. As an HTML consumer, you are supposed to parse that content and notice the tag, which says "here is something that should have been one of the HTTP headers". In this case, it wants you to act as though you saw: Refresh: 0;URL=http://tech.163.com/04/1110/12/14QUR2BR0009159H.html Pragma: no-cache In this case, the "Refresh" header means that you are supposed to go fetch the contents of that new page immediately.

IMAP mailwatcher w/Tkinter

Re: Use of Python with GDAL. How to speed up ?
Thank you Serge for this generous reply, Vectorized code seems a great choice to compute the distance. If I understand well, vectorized code can only work when you don't need to access the values of the array, but only need to know the indices. This works well for the distance, but I need to access the array values in the openness function. As regards array.array, it seems a bit complicated to reduce all my 2D arrays to 1D arrays because I am working with the gdal library, which works only with 'numeric' arrays.

Because the class is a decorator for many controller functions, and each controller function will need it's own set of descriptors, so I don't want to mess with the class. Think of the decorator as a prototype, each controller function customizing it according to it's need - this customisation including the decorator instance attaching descriptors and methods to itself according to parameters passed at __init__ time. The decorator instance also passes itself as first arg to the controller function - which then practically become an instance method too. Don't tell me, I know this is a somewhat weird architecture, and it could mostly be done with more conventional subclassing. BTW, this was how a first implementation worked, and it required almost twice more code than the new one I'm experimenting, without being half as flexible. As I said, it's mostly syntactic sugar, but what, I'm lazy enough to spend time on writing code that will allow me to write less code in the end !-) -- bruno desthuilliers python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for p in '[EMAIL PROTECTED]'.split('@')])" -- http://mail.python.org/mailman/listinfo/python-list

Strange metaclass behaviour
Hi, I think I have discovered a problem in context of metaclasses and multiple inheritance in python 2.4, which I could finally reduce to a simple example: Look at following code: class M_A (type) : def __new__ (meta, name, bases, dict) : print "M.__new__", meta, name, bases return super (M_A, meta).__new__ (meta, name, bases, dict) class M_B (M_A) : pass class A (object) : __metaclass__ = M_A class B (object) : __metaclass__ = M_B class D (A, B) : pass One would expect that either 1) D inherits the metaclass M_A from A 2) or python raises the well known "Metatype conflict among bases" error Instead, if you run this code, you get the following output: M.__new__ A (,) M.__new__ B (,) M.__new__ D (, ) M.__new__ D (, ) This means that when class D gets defined, the __new__ from M_A get executed twice (first from M_A, then from M_B), which should not happen. This suggests that either 1) cooperative supercalls do not work here 2) the metaclass of EACH of the bases of D does it's work independently when D is defined. Does anyone have a detailed explanation here ? Is this problem already known ? regards chris -- http://mail.python.org/mailman/listinfo/python-list

Sorry to have caused all that confusion. The quote from RFC822 I gave is really confusing and is indeed not relevant to the original question. As Tim pointed out, the "to_addrs" parameter in smtplib.py::sendmail is translated to the SMTP RCPT TO and thus must contain all the intended recipients whether they are logically To, CC, Bcc. That parameter cannot be empty, and that is not a restriction in Python, but a restriction of the nature of email: No recipient, no transmission. It is true that even with RFC 822 it was allowed to have NO To: line, but NOT an empty To: line, while it was allowable to have an empty Bcc: line.

No. At least not easily. You'd have to write the whole image-header loading yourself. Which is certainly more than a two-week-old python coder is capable of.

PIL: Breaking/Wrapping lines "automatically"
Hi! Is there something I can do in PIL to restrict a line to a certain size and have it to break/wrap into a newline automatically? (Or by using some code, of course...)

I've often noticed that programming for me is akin to composing music. Now let me start by saying that while I can hum pretty well, I'm not a musician of any sort, so this is based upon the experiences related to me by others who are (btw, there seems to be a very large overlap between programmers and musicians...). I can be mulling over a particular problem for hours, sometimes days, and do nothing but write some pseudo-code or a couple of trial programs that don't really do what is needed. Then, at some unpredictable point, clarity sets in and I see the solution. After that, it's just a matter of transferring that into code (for which Python is by far the best language, as it doesn't get in my way). The people I know who write music tell me of a similar process: they play a few bars or write a few words, but it doesn't feel quite right. Then either a particular musical hook comes to mind, or a set of words that solidifies the image of what they were feeling, and after that the song is written in their head and just needs to be transferred to tape (or bits, as is more common these days). I can't wake up one day and plan my day like this: 9-12, write some killer algorithm; 12-1, run errands and eat lunch; 1-3, add algorithm to existing code and refactor; etc. Nor can the musicians I know plan of writing the first stanza of a song in the morning, the second after lunch, and the chorus in the evening. The other similarity is that some musicians tend to be more creative when off by themselves, while the rest seem to feed off of jamming together with others. Most of them strongly prefer one or the other; rarely do they employ both. The comparison to programmers would be that I seem to resemble the former type, while you seem to resemble the latter. I strongly agree on the benefit of code review, though, especially in my case where things tend to get written more or less unconsciously. While the main problem may be addressed well, there are either side/end cases that still need to be addressed, or there is an opportunity to refactor to make it fit in much better with the project as a whole. A partner who is not emotionally immersed in the code can usually see these things better than the person who created the code. > Wanna talk debugging?

OK, we part ways on the plushie thing, but here I have to agree with you: a second set of eyes (and brain patterns) helps immeasurably when debugging. I think the key here is having to explain what you did and what you thought the code should have done to someone else clarifies the problem, whether it's explaining it to someone else in the room, or trying to explain it in an email to a list like this. I can't even begin to count the number of times that I've been stuck, and decided to post the problem to a list for help, and in the process of composing the email, figured out what my mistake was! Those netiquette guidelines for posting intelligently aren't to help the readers of the post; they're to help you form your scattered thoughts into a coherent picture, and more often than not, if it's a bug that I've created rather than a gap in my understanding, the process of writing the email is all I need. I guess if there's a point to all of this, it's that good programming is a creative process, and that you need to identify what works and doesn't work for you. There is no one-size-fits-all a
Building files within a package
Hi All, I am creating a python package that contains a whole pile of functions that build lookup tables. Since these lookup tables will not be changing, I would like to have setup.py create a lut_static.py fie from the lookup table code (lut.py). What is the best way to do this so that when I install the package the static tables get build? It basically looks like this foo-py-0.1 setup.py foo lut.py lut_static.py <- want to generate this from lut.py For development, it is easy enough for me to have a Makefile in foo that creates lut_static.py when ever lut.py is changed, but I would like to make setup.py handle this so if someone tweaks the lut.py and reinstalls it, they don't have to know about foo/Makefile Thanks! -kurt -- http://mail.python.org/mailman/listinfo/python-list

Most of the other commandments can be ignored while coding Python, but the 7th certainly applies here. http://www.lysator.liu.se/c/ten-commandments.html As I've written before, the ISO 8601 spec contains many variations in date formats. Making a full ISO 8601 parser is probably possible if we ignore time deltas, but it's hardly worth the effort. Writing something that parses a few percent of the possible ISO 8601 messages and calling that an ISO 8601 parser seems silly to me. With code like Skip's above it's obvious what kind of strings are handled. In typical applications, one such format is enough, and this needs to be properly specified. In a recent case I wrote the spec like this: "The timestamp shall be an ISO 8601 combination of UTC date and time with complete representation in extended format, with representation of fractions of seconds with up to six decimals preceeded by a full stop as decimal sign. E.g. 2005-06-20T13:42:55.2425Z" Despite my verbosity here, someone who didn't follow the example, would still be able to write ISO 8601 strings following the requirements above that we won't parse, since I didn't actually write that dates should be written as year-month-day.

I don't think this is bug either: the fact is that type.__new__ works differently from object.__new__, so that it is called twice in this case. Not sure if it could be avoided. Speaking of the metatype conflict, I realized a while ago that it is possible to avoid it automatically even at the pure Python level, without changing the C code for type.__new__. However, the solution is too complicate. According to the Zen of Python "If the implementation is hard to explain, it's a bad idea", thus I have never used it.

Your solution is a nice workaround, but in a quite huge and complex class framework with a lot a custom metaclasses you don't want this code in each __new__ function. And in fact each __new__ which does not contain this fix-code (and which is not completely side-effect free) might break if someone adds additional classes deeps down in the inheritance hierarchy (which is exactly what happened for me). And this is clearly not what one should expect in context of multiple inheritance and cooperative supercalls. Raising a "metatype conflict among bases" error might be a perfectly acceptable behavior here (though it would be better if python resolves the conflict as your code does), but double-executing code is not in my humble opinion.

Exponential in respect to what? You just recursively walk the automaton for every word of length n, so at most you'll have to check every word in S^n once. Hence, the complexity is not worse than the "generate and test" approach (it's in fact better, since testing is trivial). However, if the result set is simple (as in the example), then the result FSM will have states that won't have transitions for every letters, so I guess the average case will be a lot better. > For improved asymptotic complexity in this case, > you need to be able to at least reject in mid-sequence, One can do that if there is no valid transition out of some state. I guess one could even optimize on that: In the minimal automaton, every state has some transition sequence that will end up in a final state. Annotate each state with the minimum number of steps for such a sequence. While walking the automaton, keep the maximum number of letters to produce in a variable. If this number is small then the number in the annotation, stop and backtrace. This should guarantee that only those states are visited that really produce some output. - Dirk -- http://mail.python.org/mailman/listinfo/python-list

So you're trying to add property-like attributes to functions?

So you only want one decorator? Doesn't that mean that all functions will have the same attributes? But if that were true you would only need one descriptor for all controller functions, so I must not be understanding that right. Can you give a little more realistic code sample? I'm still not sure what it is you really want to do. Don't worry about showing the implementation you're thinking of. Just show me how you want to use these things and what it ought to look like.

Confused: appending to a list
I'm confused. Why is it that when I say "while len(list) < 5:", I get 5 items in my list. If I say "while len(list) < 6:", I get 6 items in the list and so on. I would think if I said "less than 5", I would get 4 items. Can anyone explain this? Thanks.

Yes - you loop until the condition is _not_ fullfilled anymore. Which means that if the list has a length of five, the len(l) < 6 is true, and appending makes it len(l) == 6 - which then will fail your condition. So - you need to loop one time less, by doing while len(l) < 6 - 1: ... diez -- http://mail.python.org/mailman/listinfo/python-list

Because the last time when len(list) was < 5, the block of code following the while executed and did something to the list to give it a length >= 5 (otherwise the block of code would be executed again and it wouldn't have been the last time). >list.append(num) There you have it. -- René Pijlman Wat wil jij leren? http://www.leren.nl -- http://mail.python.org/mailman/listinfo/python-list
