Windows zip of Numerical Python 17.1.1 available
by Paul F. Dubois 01 Nov '00

01 Nov '00

Numerical 17.1.1 is available in both source and prebuilt Windows versions at: http://sourceforge.net/projects/numpy Windows users, simply extract into your top level Python 2.0 directory, typically c:\python20. Thank you to Pete Shinners for putting the Windows file together. It is too late to change for the 17 series but in future I will make releases that have whole numbers only as names and add files to that release as they become available. That makes it a little clearer that you should take the most recent file of the desired type.

by Paul F. Dubois 01 Nov '00

01 Nov '00

The deadline for submitting a paper to the Python 9 conference is next Monday, November 6. Knowing the work habits of the Python community, I made the deadline a Monday instead of Friday. Instead of partying all weekend as usual, why not write up your work and submit it at: http://python9.org Note that the guidelines on formatting only apply to the final paper; we'll take it in any readable electronic form for now. If you want to do a poster, submit your abstract as a normal paper and just say in it that you only want it considered as a poster.

[FAQTS] Python Knowledge Base Update -- October 29th, 2000
by Fiona Czuczman 29 Oct '00

29 Oct '00

Hi Guys, What's happened in the python knowledge base since last post(9/10). regards, Fiona Czuczman ## Unanswered Questions ######################################## ------------------------------------------------------------- How do I get the UID from os.stat mapped to a real username in NT? http://www.faqts.com/knowledge-base/view.phtml/aid/6374 ------------------------------------------------------------- Lance ------------------------------------------------------------- I'm getting an error stating that "None" object has no attribute "groups" during setup of numpy, any ideas? http://www.faqts.com/knowledge-base/view.phtml/aid/6245 ------------------------------------------------------------- Michael Risser ------------------------------------------------------------- how can i create a pop up window with entry on it, so that i can get the value from the entry and process it with the original frame, thanks http://www.faqts.com/knowledge-base/view.phtml/aid/6347 ------------------------------------------------------------- tony zhang ------------------------------------------------------------- How do you access the printer from Python under Linux??? http://www.faqts.com/knowledge-base/view.phtml/aid/6376 ------------------------------------------------------------- Dave Berry ------------------------------------------------------------- How do I check and retrieve the error conditions & message of script executed via the Python/C API (without using PyErr_Print) http://www.faqts.com/knowledge-base/view.phtml/aid/6234 ------------------------------------------------------------- Kostas Karanikolas ## New Entries ################################################# ------------------------------------------------------------- How can I get my _full_ program name (eg. "mylongpythonscript.py") under eg. NT? sys.argv[0] gives me the truncated MS-DOS style, "MYLONG~1.PY" etc. http://www.faqts.com/knowledge-base/view.phtml/aid/6159 ------------------------------------------------------------- Jon Nicoll, Fiona Czuczman Alex Martelli This seems to work in my setup (2.0b2, Win98): import sys try: raise RuntimeError except: x=sys.exc_info()[2] print x.tb_frame.f_code.co_filename Placing this in alongfilename.py and running python alongfilename.py results in the expected output: alongfilename.py ################################################## # Under (NT4, Python v1.5.2), the above also gives # the 'short' form for me. # This is a bit more Win32 specific, but works for my environment import sys import win32api print win32api.FindFiles(sys.argv[0])[0][8] ## Edited Entries ############################################## ------------------------------------------------------------- Where can I best learn how to parse out both HTML and Javascript tags to extract text from a page? http://www.faqts.com/knowledge-base/view.phtml/aid/3680 ------------------------------------------------------------- Paul Allopenna, Matthew Schinckel, Magnus Lyckå Python Documentation If you want to (quickly) strip all HTML tags from a string of data, try using the re module: import re file = open(filename,'r') data = file.read() file.close() text = re.sub('<.*?>', '', data) #Remove comments first, or '>' in #comments will be interpreted as #end of (comment) tag. text = re.sub('', '', text) This will also strip any javascript, but only if the page has been made 'properly' - that is, the javascript is within HTML comments. If you want to know how it works, read the 're' chapter in the library reference, as it discusses the usefulness of 'non-greedy' regular expressions. ------------------------------------------------------------- How do I change the name of a process (as viewed by 'ps') from Python? http://www.faqts.com/knowledge-base/view.phtml/aid/6149 ------------------------------------------------------------- Adam Feuer, Fiona Czuczman Oleg Broytmann Don't know much about Mac. Probably, there is no such thing as "process name". :) On Windows, it is possible, and I saw a code doing that. Probably, Mark Hammond was the author, if I remember it right. On UNIX it is impossible now. To do this, someone will need to wrap one of "setproctitle" sources. The most known code is "setproctitle" from sendmail, but it accompanied with not-so-free license. More liberal license is for similar code in PostgreSQL, so if anyone is interested to do some work and produce a working module - PostgreSQL is a good place to start.

PythonLabs Team Moves to Digital Creations
by Guido van Rossum 28 Oct '00

28 Oct '00

To all Python users and developers: Less than half a year ago, I moved with my team to BeOpen.com, in the hope of finding a new permanent home for Python development. At BeOpen, we've done several good things for Python, such as moving the Python and Jython development process to SourceForge, and the successful release of Python 2.0. Unfortunately, BeOpen.com's original plans for PythonLabs didn't work out as hoped, and we weren't able to reach mutual agreement on workable alternative plans -- despite trying for months. I am proud to have found a new home for my entire team: starting today, Tim Peters, Barry Warsaw, Jeremy Hylton, Fred Drake and myself are working for Digital Creations. We will be spending part of our time on core Python development (including Jython and Mailman) and part of our time on Python infrastructure improvements that also benefit Zope. Python will remain Open Source; Digital Creations has no desire to monetize or brand the Python language or specific Python distributions. All future work we do on Python as Digital Creations employees will be owned by a non-profit organization yet to be created. We think of this new organization as the Python Software Foundation. In the meantime (while the PSF is under construction) I will own such copyrights personally. We're excited to be working for Digital Creations: they are one of the oldest companies active in the Python community, one of the companies most committed to Python, and they have a great product! Plus, we know they have deep financial backing. We trust that Digital Creations will provide a stable home for Python for many years. Digital Creations has also offered to take over hosting of the python.org and starship sites. On behalf of the Python community, we're grateful for this support of the two prime community sites for Python, and we expect to be implementing the transitions shortly. These are exciting times for the PythonLabs team -- and also for Python and its community. Mainstream successes for Python are showing up everywhere, and we're proud to be a part of such a smart and friendly community. A great year lies ahead! --Guido van Rossum (home page: http://www.python.org/~guido/)

ANNOUNCE: wxPython 2.2.2
by Robin Dunn 27 Oct '00

27 Oct '00

wxPython 2.2.2 has finally been released! You can get your copy at http://wxPython.org/download.php. At that site you'll find the sources, docs, and binaries for Linux and Win32 for both Python 1.5.2 and Python 2.0 Here's an excerpt from the CHANGES.txt file: New in 2.2.2 ------------ Significantly changed how the wxStyledtextCtrl code that wraps Scintilla is implemented. Most of it is now automatically generated from an interface definition file provided by Scintilla. This means that it will be much easier to stay in sync with new Scintilla releases, but also means that some of the method and identifier names have changed. See wxPython/demo/data/stc.h for a copy of the C++ interface from which the Python interface is generated. There is now some inline documentation in that file that should really help explain how things work. I am now using the Python Distutils to build wxPython and to make some of the distribution files. (See http://www.python.org/sigs/distutils-sig/) This means no more messing with my kludgy build.py/Makefile hack, builds will be more consistent with other Python extensions that also use Distutils, and will hopefully make wxPython easier to build for platforms where there have been troubles before. If you are building wxPython for Python 1.5.2 or for 1.6, then you will need to get and install version 1.0 of Distutils from the website above. If you are using Python 2.0 then you already have it. Added wxInputStream and the wxFileSystem family of classes, contributed by Joerg Baumann. Added wxProcess and support for it to wxExecute. wxProcess lets you get notified when an asyncronous child process terminates, and also to get input/output streams for the child process's stdout, stderr and stdin. Removed the old python sizers. Added __add__, __sub__ and __cmp__ (equality check only) for wxPoint and wxRealPoint. Changed the build to make one big extension module instead of one for the core and each contrib. This allowed me to do away with the libwxPyHelpers.so on unix systems. Lots of little fixes here and there. Some hacks on wxGTK to try and make the AutoComplete listbox in the wxStyledTextCtrl to behave better. It's still not as nice as on wxMSW, but at least it's a bit more usable now. -- Robin Dunn Software Craftsman robin(a)AllDunn.com http://wxPython.org Java give you jitters? http://wxPROs.com Relax with wxPython!

[ANN] Creating Py Extensions Using Borland's Free Compiler v3.0
by Gordon Williams 25 Oct '00

25 Oct '00

*** Creating Python Extensions Using Borland's Free Compiler V2.0*** I am pleased to announce a set of step-by-step instructions and examples to create extensions using the free Borland Command Line Compiler with the standard Python Windows Binary Distribution. This information can be found at http://www.cyberus.ca/~g_will/pyExtenDL.shtml . Version 3.0 updates the linking library to Python 2.0 and removes an obsolete patch for the Python 1.5.2 config.h file. I have also added a section about using VIDE (http://www.objectcentral.com/), a free and useful IDE for Borland and other compilers. ********************************************************************** ABSTRACT This paper describes the method used to create Python Extensions using the Borland 5.5 C++ Compiler (BCC). This command line compiler is available free from http://www.borland.com/bcppbuilder/freecompiler/. I describe the steps that are necessary to produce the extension from the C source code and how to set up the associated files for the compiler and linker. These extensions work with the standard Windows Distribution of Python. The process used to produce the extension is very easy and consists of running a simple batch file that I provide as part of this package. A section is provided on how to create extensions using VIDE to make it even easier. I also have some examples and a short reference section at the end of this paper that may be helpful.

Announcing Jython, the sucessor to JPython
by barry＠wooz.org 19 Oct '00

19 Oct '00

Hello JPython users, I'm very happy to announce the formation of the Jython project on SourceForge. Jython is the successor to JPython, the Java implementation of the Python programming language. We've created this new project in accordance with the CNRI JPython 1.1.x license, in order to ensure the continued existence and development of this important piece of Python software. The intent is to manage this project with the same open policies that are serving CPython so well. Finn Bock and I have been working on the next release, to be called Jython 2.0. Finn has integrated his JPython errata, and Python 2.0 language features such as augmented assignments, list comprehensions, and extended print have also been added. The free Apache Jakarta OROMatcher software has taken the place of the previously non-free OROMatcher code for regular expressions, so there will be no further need to dual license. Jython 2.0 will eventually be released with a license similar to CPython 2.0. I don't know when the first alpha release of Jython 2.0 will happen, but all the code is currently available in the SourceForge CVS tree. I will also be converting the old Jitterbug database to the SF bug tracker as soon as possible. I've created several mailing lists to support Jython development: jython-users(a)lists.sourceforge.net This list will supplant jpython-interest(a)python.org and should be the general discussion list for Jython users. jython-dev(a)lists.sourceforge.net This is an analog to python-dev(a)python.org, except that it will have an open subscription policy. This is the place for Jython developers to discuss and help move the Jython project further. jython-announce(a)lists.sourceforge.net A low-traffic, announce only list. jython-checkins(a)lists.sourceforge.net Similar to python-checkins(a)python.org, this list will receive CVS checkin and diff messages. All these mailing lists, and all current information on the Jython project is available at SourceForge, at http://sourceforge.net/projects/jython I will not be automatically subscribing any current jpython-interest members to the new lists; that's up to you. I know Finn joins me when I say that we look forward to working with you on Jython, and to your contributions in furthering this project's development. Cheers, -Barry
