Re: [Tutor] When you write the script how is it interpreted?

Nothing much to write about. The standard CPython interpreter then writes proprietary 'PyCode'. (It is proprietary in the sense of being specific to the interpreter.) The Jython interpreter instead write JCode (or whatever the internal Java bytecode is called). Terry J. Reedy

code.InteractiveConsole in a newly created xterm
by Simon Budig Jan. 31, 2002

Jan. 31, 2002

Hi all. The following works great: import code def python_inter(): ip = code.InteractiveConsole () ip.interact ("Python interactive Console") However, I want to have this in a freshly created xterm window and I have not been able to figure this out. I guess I somehow have to use pseudo terminals and the xterm "-S" option. Something like (pseudocode): import code,spam def python_inter(): xterm = spam.create_xterm_instance () ic = code.InteractiveConsole () ic.connect_to_xterm (xterm) ic.interact ("Python interactive Console") xterm.close () Is this possible? For as much Unix-like platforms as possible? Thanks! Simon -- Simon.Budig(a)unix-ag.org http://www.home.unix-ag.org/simon/

[ANN] HMM-0.1
by alf＠leo.logilab.fr Jan. 31, 2002

Jan. 31, 2002

hmm is a python module designed to work with Hidden Markov Models. Usual algorithms (Viterbi, Baum-Welsh) are implemented using Numeric Python. This module has been tested with Python 2.1 and NumPy-20.3, but it should work with python 2.2. The home page of the project is http://www.logilab.org/hmm/ Discussions about hmm should take place on the ai-tools(a)logilab.org mailing list. More information on the list can be found at http://lists.logilab.org/mailman/listinfo/ai-tools/ Alexandre Fayolle -- LOGILAB, Paris (France). http://www.logilab.com http://www.logilab.fr http://www.logilab.org Narval, the first software agent available as free software (GPL).

Re: Calendars and recurring events

> I'd like the user to be able to specify "repeat once a year", "repeat > until ddmmyyyy", "repeat every two weeks", "repeat first Monday of the > month" etc etc. I've given some thought to this as well. There's a program called 'pcal' that generates calendars from event files. One might wrap the relevant source of pcal w/a SWIG wrapper and generate a python extension that handles the date parsing / validation.

Absence of Python from ZDNet "coder's toolkit" list
by David Lees Jan. 31, 2002

Jan. 31, 2002

ZD Net has an e-mail newsletter called 'ZD Net Software Express'. The version for today (Jan 31) has a link titled 'A software coder's toolkit' which links to a list of downloads for Java, Perl and C++, but no Python. I just sent a polite note to the publisher at zdnetcare(a)cnet.com suggesting they may want to publish a link to python.org. Others might be interested in doing the same. I also note that the ZDNet download site search engine comes up with Python 1.5.2 at the top of its list with downloads for both Windows and Linux, but only has the Windows download for 2.1.1 from ActiveState.

import win32com in embedded python
by Achim Domma Jan. 31, 2002

Jan. 31, 2002

Hi, if I try to import win32com in an embedded python interpreter I get the following error message : Traceback (most recent call last): File "PythonISAPI", line 2, in ? File "c:\python21\win32com\__init__.py", line 95, in ? SetupEnvironment() TypeError: this constructor takes no arguments I looked at the given file but the error makes no sense at all to me. win32com works fine from the command line and importing other packages is also no problem. Any idea ? greetings Achim

Pmw problem
by dlarnold＠west.com Jan. 31, 2002

Jan. 31, 2002

Anyone know what's causing this? : Python 2.1.1 (#20, Jul 20 2001, 01:19:29) [MSC 32 bit (Intel)] on win32 Type "copyright", "credits" or "license" for more information. >>> import Pmw >>> root = Pmw.initialise() Traceback (most recent call last): File "<stdin>", line 1, in ? File "Pmw\Pmw_0_8_5\lib\PmwLoader.py", line 134, in __getattr__ self._initialise() File "Pmw\Pmw_0_8_5\lib\PmwLoader.py", line 88, in _initialise basemodule = self._getmodule(path + '.Pmw' + _BASEMODULE) File "Pmw\Pmw_0_8_5\lib\PmwLoader.py", line 72, in _getmodule mod = sys.modules[modpath] KeyError: _Pmw.Pmw_0_8_5.lib.PmwBase >>> What am I missing here? Pmw was installed to C:\PYTHON21\PMW, and I have a '.pth' file entry for that directory. That must be okay, since the import doesn't generate an ImportError.

float limits
by alf＠leo.logilab.fr Jan. 31, 2002

Jan. 31, 2002

Hi, Is there a way of knowing what the value of the smallest positive float available on a given machine from within python? A bit like sys.maxint, but for mindouble. Similarly, I'd like to know the value of the biggest positive float, maxfloat. If the solution is portable, that's all the better.
