IMDbPY 2.7
IMDbPY 2.7 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about both movies and people. With this release some major bugs were fixed, especially in the http and mobile data access systems; searches which return a lot of results are handled gracefully. Platform-independent and written in pure Python (and few C lines), it can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page. -- Davide Alberani [EMAIL PROTECTED] [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/ -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

The old grep module depends on the regex module, which has been deprecated since Python 1.6, and which was finally removed in Python 2.5. My doubt is are the other forms of grep like egrep and ggrep be used instead? there are no such modules in Python, afaik. (and that's a question, not a doubt, right?) if you have Python code that uses the grep module, you can replace it with something like: import re def simple_grep(filename, pattern): find = re.compile(pattern).search for index, line in open(filename): if find(line): print filename, index, line[:-1] where pattern is an RE-style pattern, not a REGEX-style pattern (see the RE documentation for details). /F -- http://mail.python.org/mailman/listinfo/python-list

Right-double-quote is not an HTML special, so there's no need to quote it. I'm only concerned here with characters that have special meanings in HTML markup. There is no need to quote or ' either except in particular situations. Would you care to suggest how you get a right double quote into any iso- 8859-1 encoded web page without quoting it? Even if the page is utf-8 encoded quoting it can be a good idea. There should be a one-stop shop where I can take my unicode text and convert it into something I can safely insert into a generated html page; at present I need to call both cgi.escape and s.encode to get the desired effect. What you're really asking for is a version of cgi.escape that a) fixes the bugs discussed in this thread, and b) copes with different encodings while doing so. To handle b), you would need to pass it some indication of what the encoding of the string is. In any case, converting a literal right-double-quote to #8221; is not relevant to the purpose of cgi.escape. You don't seem to understand about html entity escapes. #8221; is a valid way to express right double quote whatever the page encoding.

If I may add another thought along the same line: regular expressions seem to tend towards an art form, or an intellectual game. Many discussions revolving around regular expressions convey the impression that the challenge being pursued is finding a magic formula much more than solving a problem. In addition there seems to exist some code of honor which dictates that the magic formula must consist of one single expression that does it all. I suspect that the complexity of one single expression grows somehow exponentially with the number of functionalities it has to perform and at some point enters a gray zone of impending conceptual intractability where the quest for the magic formula becomes particularly fascinating. I also suspect that some problems are impossible to solve with a single expression and that no test of intractability exists other than giving up after so many hours of trying. With reference to the OP's question, what speaks against passing his texts through several simple expressions in succession? Speed of execution? Hardly. The speed penalty would not be perceptible. Conversely, in favor of multiple expressions speaks that they can be kept simple and that the performance of the entire set can be incrementally improved by adding another simple expression whenever an unexpected contingency occurs, as they may occur at any time with informal systems.

Re: where are isinstance types documented?

Hi,
I'm using the isinstance built-in function. I've found the docs for it,

It supports *all* types.
For example isinstance(a, int) works fine but isinstance(s, string)
doesn't - because 'string is not known'.
That's because there is no built-in type called string.
I do know how to import the types module and then use defined types
such as 'types.StringType' - but the documentation says that from 2.2
this is not the preferred way.
So, where's the documentation for types I can use with isinstance, such
as 'int'?
This is must-read stuff, but doesn't give the actual type names:
http://docs.python.org/ref/types.html
What you are looking for is this:
http://docs.python.org/lib/types.html
which is also must-read, but you may find it faster to use the Who's
your father? technique on a known instance:
| type([])
| type 'list'
| type('')
| type 'str'
| type(u'')
| type 'unicode'
| isinstance('foo', str)
| True
| isinstance('foo', unicode)
| False
Who's your grandfather? can be useful, too:
| str.__mro__
| (type 'str', type 'basestring', type 'object')
| isinstance('foo', basestring)
| True
| isinstance(u'u2', basestring)
| True

I was hoping to add and remove instruments.. although the other should
go into my example file because it will come in handy at some point.
It would also be cool to get a list of instruments along with any

functions.

Eric,
Below the dotted line there are two functions.
csound_filter () extracts and formats instrument blocks from
csound files and writes the output to another file. (If called without
an output file name, the output displays on the screen).
The second function, make_instrument_dictionaries (), takes the
file generated by the first function and makes two dictionaries. One of
them lists instrument ids keyed on instrument description, the other one
does it the other way around, listing descriptions by instrument id.
Instrument ids are file name plus instrument number.
You cannot depend on this system to function reliably, because it
extracts information from comments. I took my data from
ems.music.utexas.edu/program/mus329j/CSPrimer.pdf the author of which
happens to lead his instrument blocks with a header made up of comment
lines, the first of which characterizes the block. That first line I use
to make the dictionaries. If your data doesn't follow this practice,
then you may not get meaningful dictionaries and are in for some
hacking. In any case, this doesn't look like a job that can be fully
automated. But if you can build your data base with a manageable amount
of manual work you should be okay.
The SE filter likewise works depending on formal consistency with
my sample. If it fails, you may have to either tweak it or move up to a
parser.
I'll be glad to provide further assistance to the best of my
knowledge. But you will have to make an effort to express yourself
intelligibly. As a matter of fact the hardest part of proposing
solutions to your problem is guessing what your problem is. I suggest
you do this: before you post, show the message to a good friend and edit
it until he understands it.

George Sakkis wrote: [Oslo, Norway short of 300-500 Java developers] Um, how many of these lots of Java developers looking for work live in, or are willing to relocate to, Oslo? Well, I really meant to say that the lots of Java developers I've seen actually are in Oslo. Certainly, every time this topic comes up in some article, people tend to complain about a mismatch between employer claims and their own experiences trying to get hired, and there wouldn't be much of a debate if those people were not within commuting distance. Another point might be that many ads prefix the offered position with senior, and my guess is that most of those looking for work don't really qualify, for any reasonable definition of senior. It's quite possible that a lot of the people out in the job market don't have the experience with Java that employers supposedly demand, although in many cases that isn't anything to do with how long they've been in the business (one definition of senior). However, I'd question the need only for senior developers in a market for a particular technology, since it would suggest that either everyone seems to think that they're doing rocket science, or the technology isn't the most appropriate or efficient way to do the work (especially given the supposed lack of developers). However, knowing the corporate/political undercurrents behind some of these recruitment advertorials, I might suggest that many of these supposedly available Java positions don't actually exist. If the handful of advertised Python positions do actually exist, on the other hand, we can at least estimate the prospects of Python practitioners with more certainty.

You only need the first one, since every database interface that follows PEP 249. I guess I don't have a strong preference for which way we do it, but I would suggest confining our discussion to non-stupid solutions. Good suggestion.

Re: Logfile analysing with pyparsing
You can parse it just once, you just have to setup your data structure
(the structure of your XML schema) and fill it up as you parse.
For example, you can represent you data structure as a dictionaries in
Python:
message={
MID : {
' timestamp' : TIMESTAMP,
'from':FROM,
'tolist':[TO1, TO2, ... ],
'qids': [QID1, QID2, ...],
'spam_score':S_SCORE,
'spam_filtered':Y/N,
'spam_sentdo':S_SENDTO,
}
}
Note: I inferred this from your XML.
Then as you parse each record(line?) identify what token is what and
fill in the corresponding data structure. So if you pass by a line that
has the message_id, queue_id and a send_to fields, check if the
corresponding message_id dictionary has been created (if not do so) and
fill in what you just found out. Later on you might see another record
that will help you fill in other information regarding this particular
message_id (such as a 'timestamp' or a 'from' field).
Then translating the data into XML should be fairly easy.
Note: I am not familiar with the syntax of the mail log so I presented
a general idea only. My assumptions about the syntax might have been
wrong.
Hope this helps,

You may be surprised by the version number since we have been missing public annoucements recently, and the 0.12.0 version has not really been announced. To quote Alexandre, we got a bit sloppy in the public part of our release process, and the mails did not fly... Hopefuly we'll be better on this in a near future. Anyway there has been a lot of usability changes and a lot of bug fixes making pylint more stable (at least since the type inference has been introduced...) and nicer to configure and use, so please upgrade to this version, along with the latest logilab-common and logilab-astng version (this relelase of pylint actually depends on astng = 0.16.1). I hope you'll enjoy this release and would like to thanks everybody who contribute to pylint/astng by sending feedback or even better patch on the mailing list :) Enjoy ! What's new ? :Changes in 0.12.1 * fixed python = 2.4 format false positive with multiple lines statement * fixed some 2.5 issues * fixed generator expression scope bug (depends on astng 0.16.1) * stop requiring __revision__ :Changes in 0.12: * usability changes: - parseable, html and color options are now handled by a single output-format option - enable-checkerid and disable-all options are now handled by two (exclusive) enable-checker and disable-checker options taking a comma separated list of checker names as value - renamed debug-mode option to errors-only * started a reference user manual * new W0212 message for access to protected member from client code (close #14081) * new W0105 and W0106 messages extracted from W0104 (statement seems to have no effect) respectivly when the statement is actually string (that's sometimes used instead of comments for documentation) or an empty statement generated by a useless semicolumn * reclassified W0302 to C0302 * fix so that global messages are not anymore connected to the last analyzed module (close #10106) * fix some bugs related to local disabling of messages * fix cr/lf pb when generating the rc file on windows platforms What is pylint ? Pylint is a python tool that checks if a module satisfy a coding standard. Pylint can be seen as another pychecker since nearly all tests you can do with pychecker can also be done with Pylint. But Pylint offers some more features, like checking line-code's length, checking if variable names are well-formed according to your coding standard, or checking if declared interfaces are truly implemented, and much more (see http://www.logilab.org/projects/pylint/ for the complete check list). The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. The usage it quite simple : $ pylint mypackage.mymodule This command will output all the errors and warnings related to the tested code (here : mypackage.mymodule), will dump a little summary at the end, and will give a mark to the tested code.

What I had in mind was: where surname = 'O''REILLY' install_dir = C:\\Python25 ... print The interest rate is %.2f%% p.a. % (rate * 100.0) the common pattern being that the problem character is doubled. Which doesn't apply to the $ character in *nix shell command lines. I'll take your word for it; it's been quite a while :-) *Something* in the dim dark past worked like that; I thought maybe I was thinking of m4, but that gets by without doubling. Your score so far is 1 out of 3; you have two more to go to match your original assertion None of which applies Cheers, John -- http://mail.python.org/mailman/listinfo/python-list

From the docs for GNU Make: Because dollar signs are used to start make variable references, if you really want a dollar sign in a target or prerequisite you must write two of them, `$$' (see How to Use Variables). If you have enabled secondary expansion (see Secondary Expansion) and you want a literal dollar sign in the prerequisites lise [sic], you must actually write four dollar signs (`').

Re: Remap Mysql tuple to dictionary
SQL databases like MySQL are _designed_ for efficiency. Efficiency with respect to what? That statement is plain wrong. They are designed for a pretty general case of data storage efficiency, in the domain of relational algebra. And for a lot of use-cases, they offer a good ratio of ease-of-use, speed and reliability and the overhead they introduce. But there are lots of cases where hand-tailored data structures - in python as well as in C - are way better suited. Think of graph representations for example, especially for reachability queries and the like. Does google use ORACLE (or whatever DB) for their index? Nope. So - without knowing the usecase, All right, sorry, looks like they want to load the entire table into RAM and key it off the first field. Kind of defeats the point of having SQL, but there you go... is a pretty strong thing to say. Diez -- http://mail.python.org/mailman/listinfo/python-list
Re: QuoteSQL
Lawrence D'Oliveiro enlightened us with: Because quoting the wildcards introduces backslash specials before each wildcard. Quoting non-wildcards then causes those backslashes to be doubled, which means they escape themselves instead of the wildcards. I don't know about other DBMSes, but in PostgreSQL you can use any escape character for the pattern, check out http://www.postgresql.org/docs/8.0/interactive/functions-matching.html Sybren -- Sybren Stüvel Stüvel IT - http://www.stuvel.eu/ -- http://mail.python.org/mailman/listinfo/python-list
