[ANNOUNCE] gmpy 1.0 alpha released
by Alex Martelli 12 Nov '05

12 Nov '05

See http://gmpy.sourceforge.net/ for details. What is it: a wrapper for the GMP library, to provide multi-precision arithmetic for Python. Multi-precision floats, and unbounded-precision rationals, are not present in stock Python; multi-precision integers ('long') are, but gmpy's version of multi-precision integers is faster for some operations (NOT all -- used to be, but Python 2.3 did serious enhancements to some operations on longs) and provides lots of nifty pre-packaged additional functions. Minor changes and bug-fixes since the latest 0.9 pre-alpha; support for Python 2.3. The Windows binary release is now for Python 2.3 _only_ (if you're stuck with Python 2.2 on Windows, you can keep using gmpy 0.9 pre-alpha and not really suffer from that). Known bug on Windows: the scan0 and scan1 functions appear broken (perhaps related to the lack of a GMP 4.0 library for Windows -- haven't found one around yet). Alex

py_mpgedit SDK 0.1 beta has been released. Download the py_mpgedit SDK: http://www.mpgedit.org/mpgedit/download_sdks.html Browse the documention: http://www.mpgedit.org/mpgedit/sdk/py_mpgedit.htm ----- py_mpgedit is the mpgedit SDK python extension for Linux and Windows. mpgedit Software Development Toolkit (SDK) is a library exporting core editing, playback and indexing functionality. It edits and plays MP3 files (MPEG 1 layer 1/ 2/3, MPEG 2, and MPEG 2.5 audio files). Using this toolkit, developers can create their own MP3 editing applications. Here is a sample session demonstrating editing and playback of an mp3 file using this extension. This creates a file new.mp3 from seconds 6 to 12 of old.mp3, then plays new.mp3. >>> import mpgedit >>> spec = mpgedit.Spec() >>> spec.append('old.mp3', '6-12') >>> mpgedit.Index('old.mp3').index() >>> mpgedit.Edit(spec, 'new.mp3').edit() >>> mpgedit.Play('new.mp3').play() mpgedit home page: http://www.mpgedit.org mpgedit SDK on freshmeat: http://freshmeat.net/projects/mpgedit_sdk

PyProtocols 0.9.1 Released
by Phillip J. Eby 28 Nov '03

28 Nov '03

What is PyProtocols? -------------------- PyProtocols is an extended implementation of PEP 246, adding a new "declaration API" that lets you easily define your own interfaces and adapters, and declare what adapters should be used to adapt what types, objects, or interfaces. Using PyProtocols, you can easily make flexible frameworks that you or other developers can extend without needing to modify the base framework. PyProtocols interfaces can interoperate with those of Twisted and Zope, or can be used entirely standalone. PyProtocols may be used, modified, and distributed under the same terms and conditions as Python or Zope. What's new in version 0.9.1? ---------------------------- * Implemented Samuele Pedroni's "subproto" idea (see http://mail.python.org/pipermail/python-dev/2003-June/036242.html) as the new 'protocolForType()' API. * Added other APIs to automatically generate protocols, such as 'protocolForURI()', 'sequenceOf()', and 'Variation()'. * Compatible with Zope X3 Milestone 4, Python 2.3.2, and Twisted 1.1.0. (Also runs on Python 2.2.2+, if you don't need Zope 3 compatibility.) * New 'Adapter' and 'StickyAdapter' convenience base classes * Fixes for compatibility with 'ExtensionClass', and for a memory leak in the optional C "speedups" module PyProtocols Resources --------------------- * Detailed Changes since the 0.9 release: http://peak.telecommunity.com/protocol_api/CHANGES.txt.html * Release notes, installation instructions, and browsable API docs: http://peak.telecommunity.com/protocol_api/ * Source and Binary Releases: http://peak.telecommunity.com/dist/ * Reference Manual (HTML): http://peak.telecommunity.com/protocol_ref/module-protocols.html * Reference Manual (PDF): http://peak.telecommunity.com/protocol_ref.pdf * Browsable CVS Repository: http://cvs.eby-sarna.com/PyProtocols/

mike, uninsured, homeless
by Bruce Reilly 27 Nov '03

27 Nov '03

Dear Judges, Lawyers, Policemen, Guards, Counselors, Taxpayers, et. al., We are here. Like it or not, for good or bad, we are here. Who are we? We are the downtrodden and dispossesed, the self-torturing, the disenfranchised convicts, drug and alcohol addicts, the unemployed and unemployable. We are the children of poverty, financial and spiritual. We have and will have children of our own, grandchildren too. We are ex-cons, uninsured, homeless, of many colors and speaking many tongues. We are the enemy in what has become a domestic war against ourselves. And who are you? You who like the tough talk of Tough on Crime? You who watch as budgets are cut in education and health care while you militarize a police force? Bullet-proof vests, automatic weapons, helicopters, tanks, robots ... the testosterone is oozing through the streets, more prisons, longer sentences, tighten the belt, spartan conditions, task forces, gang units, gun courts. And what is there to show for it? Unemployent stays low because half the population oversees those "out of the workforce", the dregs, the rabble, the enemy? Please tell me there is a deeper reason. Do you feel safer? More humane? More like a cohesive society with a shared sense of purpose, who can identify Us and Them? Do you live in a gated community or gentrified neighborhood? By the way, have you read the Declaration of Independence and US Constitution - or do you only know the first phrases? It's about time we got together. Please know that I have yet to meet a convict who wants their child to be a thief, an addict, a dealer, a prostitute, or a violent individual. Most of us still have hope for ourselves even when stuck in the darkest dilemmas, ruts and catch-22s. Most of us believe in crafting laws and instilling order. Many of us have burrowed beneath the surface to find a spiritual sense of being, an understanding force at least as powerful as those we succumbed to, and many of use wouldn't escape if you opened the front door. Did you know that approximately 10 million Americans are either incarcerated, on probation, on parole or once were in those categories? Each of those 10 million have families, friends, neighbors ... and so closer and closer does the We interface with the You. Don't you think it's time we talked? Are you ready? Can you accept that the road we are travelling points toward a grim and painful future? Do you have the heart to face monumental failures while bravely struggling beyond where we are now? I know that some of you are, and that some of us are, and this is what gives me hope. You need our insights just as we need your structure. It is never over, especially when a real solution, a real treatment for our sickness, is yet to begin. In Solidarity, Bruce Reilly (a.k.a Bruha) P.O.Box 8274 Cranston, RI 02920 USA P.S. - I am trying to conceptualize an effective guerilla media campaign to promote this cause. Ideas are welcome. Collaboration is prayed. using an e-mail proxy! Due to popular demand, an anonymous FTP site list of pictures-related "stuff" has now been compiled and is available from bongo in /gifstuff/ftpsites. This list is by no means guaranteed to be accurate or comprehensive, but hopefully most of the information is valid.

Most ftp programs will allow you to enter something like ftp wsmr-simtel20.army.mil which will connect you with the mighty SIMTEL-20 archives at the White Sands Missile Range. Occasionally, you will encounter an ftp program that is old enough or slothful enough that it does not recognize internet-style addresses like the one above. In that case, you'll need to know the computer's numeric address; for SIMTEL-20 you would

python-dev Summary for 2003-10-16 through 2003-11-15
by Brett C. 27 Nov '03

27 Nov '03

python-dev Summary for 2003-10-16 through 2003-11-15 ++++++++++++++++++++++++++++++++++++++++++++++++++++ This is a summary of traffic on the `python-dev mailing list`_ from October 16, 2003 through November 15, 2003. It is intended to inform the wider Python community of on-going developments on the list. To comment on anything mentioned here, just post to `comp.lang.python`_ (or email python-list(a)python.org which is a gateway to the newsgroup) with a subject line mentioning what you are discussing. All python-dev members are interested in seeing ideas discussed by the community, so don't hesitate to take a stance on something. And if all of this really interests you then get involved and join `python-dev`_! This is the twenty-eighth and twenty-ninth summaries written by Brett Cannon (does anyone even read this?). All summaries are archived at http://www.python.org/dev/summary/ . Please note that this summary is written using reStructuredText_ which can be found at http://docutils.sf.net/rst.html . Any unfamiliar punctuation is probably markup for reST_ (otherwise it is probably regular expression syntax or a typo =); you can safely ignore it, although I suggest learning reST; it's simple and is accepted for `PEP markup`_ and gives some perks for the HTML output. Also, because of the wonders of programs that like to reformat text, I cannot guarantee you will be able to run the text version of this summary through Docutils_ as-is unless it is from the original text file. .. _PEP Markup: http://www.python.org/peps/pep-0012.html The in-development version of the documentation for Python can be found at http://www.python.org/dev/doc/devel/ and should be used when looking up any documentation on something mentioned here. PEPs (Python Enhancement Proposals) are located at http://www.python.org/peps/ . To view files in the Python CVS online, go to http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/ . Reported bugs and suggested patches can be found at the SourceForge_ project page. .. _python-dev: http://www.python.org/dev/ .. _SourceForge: http://sourceforge.net/tracker/?group_id=5470 .. _python-dev mailing list: http://mail.python.org/mailman/listinfo/python-dev .. _comp.lang.python: http://groups.google.com/groups?q=comp.lang.python .. _Docutils: http://docutils.sf.net/ .. _reST: .. _reStructuredText: http://docutils.sf.net/rst.html .. contents:: .. _last summary: http://www.python.org/dev/summary/2003-09-01_2003-09-15.html ===================== Summary Announcements ===================== Thanks to midterms and projects my time got eaten up by school. That postponed when I could work on the twenty-eighth summary so much that the twenty-ninth was need of being written. So they are combined in into one to just get the stuff out the door. The second half of October had some major discussions happen. Guido and Alex Martelli talking equals pain for me. =) There was a large discussion on scoping and accessing specific namespaces. Jeremy Hylton is working on a PEP on the subject so I am not going to stress myself over summarizing the topic. A big discussion on the first half of November was about weakrefs and shutdown. Tim Peters figured out the problem (had to do with weakrefs referencing things already gc'ed and thus throwing a fit when trying to gc them later or keeping an object alive because of the weakref). It was long and complicated, but the problem was solved. If you have ever wanted to see linked lists used in Python in a rather elegant way, take a look at Guido's implementation of itertools.tee at http://mail.python.org/pipermail/python-dev/2003-October/039593.html . Europython is going to be held from June 7-9, 2004 in Sweden. See http://mail.python.org/pipermail/europython/2003-November/003634.html for more details. PyCon is slowly moving along. The registration site is being put through QA and the paper submission system is being worked on. The Call for Proposals (CFP) is still on-going; details at http://www.python.org/pycon/dc2004/cfp.html . Keep an eye out for when we announce when the registration and paper submission systems go live. ========= Summaries ========= ------------------------------------------ How to help with the development of Python ------------------------------------------ In an attempt to make it easy as possible for people to find out how they can help contribute to Python's development, I wrote an essay on the topic (mentioned last month, but some revisions have been done). It covers how Python is developed and how **anyone** can contribute to the development process. The latest version can be found at http://mail.python.org/pipermail/python-dev/2003-October/039473.html . Any comments on the essay are appreciated. Contributing threads: - `Draft of an essay on Python development <http://mail.python.org/pipermail/python-dev/2003-October/038677.html>`__ - `2nd draft of "How Py is Developed" essay <http://mail.python.org/pipermail/python-dev/2003-October/039473.html>`__ ------------------------------------------------ Generator Expressions: list comp's older brother ------------------------------------------------ If you ever wanted to have the power of list comprehensions but without the overhead of generating the entire list you have Peter Norvig to thank initially, and then what seems like the rest of the world, for generator expressions. `PEP 289`_ covers all the details, but here is a quick intro. You can think of generator expressions as list comprehensions that return an iterator for each item instead a list items. The syntax is practically the same as list comprehensions as well; just substitute parentheses for square brackets (most of the time; generator expressions just need parentheses around them, so being the only argument to a method takes care of the parentheses requirement). A quick example is:: (x for x in range(10) if x%2) returns an iterator that returns the odd numbers from 0 to 10. This make list comprehensions just syntactic sugar for passing a generator expression to list() (note how extra parentheses are not needed):: list(x for x in range(10) is x%2) Having list comprehensions defined this way also takes away the dangling item variable for the 'for' loop. Using that dangling variable is now discouraged and will be made illegal at some point. For complete details, read the PEP. .. _PEP 289: http://www.python.org/peps/pep-0289.html Contributing threads: - `decorate-sort-undecorate <http://mail.python.org/pipermail/python-dev/2003-October/038652.html>`__ - `accumulator display syntax <http://mail.python.org/pipermail/python-dev/2003-October/038804.html>`__ - `listcomps vs. for loops <http://mail.python.org/pipermail/python-dev/2003-October/039081.html>`__ - `PEP 289: Generator Expressions (second draft) <http://mail.python.org/pipermail/python-dev/2003-October/039356.html>`__ --------------------- list.sorted() is born --------------------- After the addition of the 'key' argument to list.sort(), people began to clamor for list.sort() to return self. Guido refused to do give in, so a compromise was reached. 'list' now has a class method named 'sorted'; pass it an iterable and it will return a sorted list. Contributing threads: - `decorate-sort-undecorate <http://mail.python.org/pipermail/python-dev/2003-October/038811.html>`__ - `inline sort option <http://mail.python.org/pipermail/python-dev/2003-October/038825.html>`__ - `sort() return value <http://mail.python.org/pipermail/python-dev/2003-October/038855.html>`__ - `copysort patch <http://mail.python.org/pipermail/python-dev/2003-October/038947.html>`__ ------------------------------------ Recursion limit in re is now history ------------------------------------ Thanks to Gustavo Niemeyer the recursion limit in the re module has now be removed! Contributing threads: - `SRE recursion <http://mail.python.org/pipermail/python-dev/2003-October/038839.html>`__ - `SRE recursion removed <http://mail.python.org/pipermail/python-dev/2003-October/038962.html>`__ ----------------------------------- Copying iterators one day at a time ----------------------------------- Reiteration for iterators came up as part of the immense discussion on generator expressions. The difficulty of doing it generally came up. This lead to Alex Martelli proposing magic method support for __copy__ in iterators that have want to allow making a copy of itself. This was written down as `PEP 323`_. As an interim solution, itertools grew a new function: tee. It takes in an iterable and returns two or more iterators which independently iterate over the iterable. .. _PEP 323: http://www.python.org/peps/pep-0323.html Contributing threads: - `Reiterability <http://mail.python.org/pipermail/python-dev/2003-October/038969.html>`__ - `cloning iterators again <http://mail.python.org/pipermail/python-dev/2003-October/039593.html>`__ - `... python/nondist/peps pep-0323.txt, NONE ... <http://mail.python.org/pipermail/python-dev/2003-October/039656.html>`__ - `Guido's Magic Code <http://mail.python.org/pipermail/python-dev/2003-October/039819.html>`__ ------------------------------------------------------ Returning Py_(None, True, False) now easier than ever! ------------------------------------------------------ Py_RETURN_NONE, Py_RETURN_TRUE, and Py_RETURN_FALSE have been added to Python 2.4. They are macros for returning the singleton mentioned in the name. Documentation has yet to be written (my fault). Contributing threads: - `How to spell Py_return_None and friends <http://mail.python.org/pipermail/python-dev/2003-October/039000.html>`__ - `python/dist/src/Include object.h, 2.121, ... <http://mail.python.org/pipermail/python-dev/2003-October/039026.html>`__ ------------------------------------------------------------------------- 'String substitutions'/'dict interpolation'/'replace %(blah)s with $blah' ------------------------------------------------------------------------- The idea of introducing string substitutions using '$' came up. Guido said that if this was made a built-in feature it would have to wait until Python 3. He was receptive to moving the functionality to a module, though. Barry Warsaw pasted code into http://mail.python.org/pipermail/python-dev/2003-October/039369.html that handles string substitutions. Contributing threads: - `Can we please have a better dict interpolation syntax? <http://mail.python.org/pipermail/python-dev/2003-October/039324.html>`__ ------------------------------------------ "reduce() just doesn't get enough mileage" ------------------------------------------ That quote comes from Guido during the discussion over whether 'product' should be added as an accumulator function built-in like 'sum'. The idea was shot down and conversation quickly turned to whether 'reduce' should stay in the language (the consensus was "no" since the function does not read well and its functionality can easily be done with a 'for' loop). A larger discussion on what built-ins should eventually disappear will be covered in the next Summary. Contributing threads: - `product() <http://mail.python.org/pipermail/python-dev/2003-October/039326.html>`__ ----------- PyPy update ----------- The PyPy_ development group sent an update on their happenings to the list. Turns out they are trying to get funding from the European Union. They are also fairly close to getting a working version (albeit with some bootstrapping from CPython, but it will still be damn cool what they have pulled off even with this caveat). They also announced a sprint they are holding in Amsterdam from Dec. 14-21. More info can be found at http://codespeak.net/moin/pypy/moin.cgi/AmsterdamSprint . .. _PyPy: http://codespeak.net/pypy/ Contributing threads: - `PyPy: sprint and news <http://mail.python.org/pipermail/python-dev/2003-October/039579.html>`__ ---------------------------- Never say Python is finished ---------------------------- I asked python-dev for masters thesis ideas. I great number of possibilities were put out. If anyone out there is curious to see what some people would like to see done for Python in terms of a large project check the thread out. Contributing threads: - `Looking for master thesis ideas involving Python <http://mail.python.org/pipermail/python-dev/2003-October/039763.html>`__ --------------------------------- Rough draft of Decimal object PEP --------------------------------- Facundo Batista has posted a rough draft of a PEP for a decimal object that is being worked on in the sandbox. Comment on it on `comp.lang.python`_ if this interests you. Contributing threads: - `prePEP: Decimal data type <http://mail.python.org/pipermail/python-dev/2003-October/039870.html>`__ ---------------------------------------------------------- Relations of basestring and bye-bye operator.isMappingType ---------------------------------------------------------- The idea of introducing relatives of basestring for numbers came from Alex Martelli. That idea was shot down for not being needed once the merger of int and long occurs. The point that operator.isMappingType is kind of broken came up. Both Alex and Raymond Hettinger would not mind seeing it disappear. No one objected. It is still in CVS at the moment, but I would not count on it necessarily sticking around (although there are rumblings that there might be a way to fix it so it is partially useful). Contributed threads: - `reflections on basestring -- and other abstract basetypes <http://mail.python.org/pipermail/python-dev/2003-November/039885.html>`__ - `operator.isMappingType <http://mail.python.org/pipermail/python-dev/2003-November/040122.html>`__ --------------------------------------------------------- Why one checks into the trunk before a maintenance branch --------------------------------------------------------- The question of whether checking a change into a maintenance branch before applying it to the main trunk was acceptable came up. The short answer is "no". Basically the trunk gets more testing than the maintenance branches and thus the patch should have to prove its stability first. Only then should it go into a maintenance branch. The same goes for changes to code that will eventually disappear in the trunk. Someone might be planning on removing some code, but if that person falls off the face of the earth the code will still be there. That means applying the patch to the code that is scheduled to disappear is still a good idea. Contributing threads: - `check-in policy, trunk vs maintenance branch <http://mail.python.org/pipermail/python-dev/2003-November/039903.html>`__ ----------------------- New reversed() built-in ----------------------- There was a new built-in named reversed(), and all rejoiced after giving the creator a thorough beating. Straight from the function's doc string: "reverse iterator over values of the sequence". `PEP 322`_ has the relevant details on this new built-in. .. _PEP 322: http://www.python.org/peps/pep-0322.html Contributing threads: - `PEP 322: Reverse Iteration <http://mail.python.org/pipermail/python-dev/2003-November/039924.html>`__ --------------------------- Cleaning the built-in house --------------------------- Guido asked what built-ins should be considered for deprecation. Instantly intern, coerce, and apply came up. apply already had a PendingDeprecationWarning and that will stay for the next release or two. intern and coerce, though, did not have any major champions (intern had some fans, but just for the functionality). Guido did state that none of these built-in will be removed any time soon. If they do get deprecated it does not lead to immediate removal. Python 3, though, takes the gloves off and that can see them just completely disappear. Contributing threads: - `Deprecating obsolete builtins <http://mail.python.org/pipermail/python-dev/2003-November/039994.html>`__ ---------------------------------------- Passing arguments to str.(encode|decode) ---------------------------------------- The idea of allowing keyword arguments be passed to any specified encoder/decoder was brought up by Raymond Hettinger. It seemed like an idea that was supported. The idea of specifying the encoder or decoder based on the actual object instead of the current way of specifying a string that is passed to the registered codec search functions was suggested. Nothing has been finalized on this idea as of now. Contributing threads: - `Optional arguments for str.encode /.decode <http://mail.python.org/pipermail/python-dev/2003-November/040055.html>`__ ------------------------------------------------------ Where, oh where, to move the good stuff out of string? ------------------------------------------------------ It looks like ascii_* and possibly maketrans from the string module will be tacked on to the str type so that the string module can finally be removed from the language. It has not been pronounced upon, but it looks like that is what the BDFL is leaning towards. Issues of using the methods of str as unbound methods did come up. As it stands you cannot pass a unicode object to str.upper and thus there is no one uppercasing function as there is in the string module. This issue brought up the problem of Unicode and locale ties and collation (how to sort things). Contributing threads: - `other "magic strings" issues <http://mail.python.org/pipermail/python-dev/2003-November/040067.html>`__ ----------------------------------------- Supported versions of Sleepycat for bsddb ----------------------------------------- The basic answer is 3.2 - 4.2 should work when you compile from source. Contributing threads: - `which sleepycat versions do we support in 2.3.* ? <http://mail.python.org/pipermail/python-dev/2003-November/040196.html>`__ ----------------------------- Sets now at blazing C speeds! ----------------------------- Raymond Hettinger implemented the sets API in C! The new built-ins are set (which replaces sets.Set) and frozenset (which replaces sets.ImmutableSet). The APIs are the same as the sets module sans the name change from ImmutableSet to frozenset. Contributing threads: - `set() and frozenset() <http://mail.python.org/pipermail/python-dev/2003-November/040253.html>`__

ANN: PyQwt-3.8
by Gerard Vermeulen 26 Nov '03

26 Nov '03

PyQwt-3.8 = FAST and EASY data plotting for Python and (Py)Qt. PyQwt is a set of Python bindings for the Qwt C++ class library which extends the Qt framework with widgets for scientific and engineering applications. It supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (either Numeric, or numarray or both) and optionally SciPy in a GUI Python application or in an interactive Python session. The home page of PyQwt is http://pyqwt.sourceforge.net. Main changes in PyQwt-3.8: 1. PyQwt inherits from Qwt the new classes QwtPicker, QwtPlotPicker and QwtPlotZoomer. QwtPicker can make any widget react to events by event filtering. QwtPlotPicker is a QwtPicker taylored to the plot canvas. QwtPlotZoomer implements infinite deep zooming on the plot canvas. 2. PyQwt inherits from Qwt the support for Qt's rich text format in QwtPlot to display equations like E=mc<sup>2</sup>. Caveat: in principle, a truetype font with full unicode support is better to typeset equations. 3. Bug fixes to support event filtering code (see EventFilterDemo.py). 4. Conversion of a QImage to a Numeric array or numarray array. 5. Better support for cloning a plot into Grace from the command line interpreter friendly plot classes. 6. PyQwt-3.8 works with PyQt-3.8.1 downto -3.6 and Qt-3.2.3 downto -2.3.0. 7. License change: GPL with permission for dynamic linking to commercial, educational and non-commercial versions of Qt, PyQt and sip. In this case PyQwt becomes a free plug-in for a non-free program.
