Hi! I just downloaded the archive of the python-dev mailing list for February 2005 from http://mail.python.org/pipermail/python-dev/2005-February.txt.gz and there is only one mail in it. Did anyone have this problem, too? Bye, Dennis

urllib2 does not seem to be able to handle META-REFRESH in an html document. I just get back the html to the page that is supposed to forward me to the intended page. Any way around this?

Text To Speech with pyTTS
by Mike P. March 4, 2005

March 4, 2005

Hi, I was wondering if anyone has had any luck with the python text to speech (pyTTS) module available on Sourceforge: http://sourceforge.net/projects/uncassist I have followed the tutorial for pyTTS at: http://www.cs.unc.edu/~parente/tech/tr02.shtml Using the first simple speech example: import pyTTS tts = pyTTS.Create() tts.Speak("Hello World!") I get the following error on the call to pyTTS.Create() C:\Program Files\Python23\Lib\site-packages\pyTTS>python ActivePython 2.3.2 Build 232 (ActiveState Corp.) based on Python 2.3.2 (#49, Nov 13 2003, 10:34:54) [MSC v.1200 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import pyTTS >>> tts = pyTTS.Create() Traceback (most recent call last): File "<stdin>", line 1, in ? File "C:\Program Files\Python23\Lib\site-packages\pyTTS\__init__.py", line 28, in Create raise ValueError('"%s" not supported' % api) ValueError: "SAPI" not supported >>> I followed the instructions in the tutorial in order and installed the required packages in the following order, given that I already had an ActiveState Python 2.3 installation under Windows XP. 1) wxPython2.5-win32-unicode-2.5.3.1-py23.exe (didn't already have this and some of the pyTTS demos need it) 2) Microsoft SAPI 5.1 (SAPI5SpeechInstaller.msi) 3) Extra Microsoft Voices (SAPI5VoiceInstaller.msi) 4) pyTTS-3.0.win32-py2.3.exe (pyTTS for Python 2.3 under windows) I ran the example and it didn't work. I didn't initially install Mark Hammond's Python win32all extensions, because they already come with ActiveState Python. So I tried installing the win32all (win32all-163.exe) package just in case, but I still get the SAPI not supported error. Anyone get this working - any suggestions? Or am I missing something obvious? Thanks In Advance. Mike P.

by zyqnews＠163.net March 3, 2005

March 3, 2005

hello all, I am new in Python. And I have got a problem about unicode. I have got a unicode string, when I was going to send it out throuth a socket by send(), I got an exception. How can I send the unicode string to the remote end of the socket as it is without any conversion of encode, so the remote end of the socket will receive unicode string? Thanks

canvassing for assistance
by sean_mcilroy＠yahoo.com March 3, 2005

March 3, 2005

Hi all! I've written a utility for making diagrams. It could also be a good environment for experimenting with a Tk canvas, so I'm including the code here (see below). The problem is that, when I save a canvas and include the resulting postscript file in a LaTeX document, I often find that the right edge of the canvas has been cut off and/or that there's a bunch of extra space at the bottom that forces the picture to take up a whole page just by itself. The Introduction to Tkinter lists a bunch of options for the Canvas postscript method, but it doesn't say anything about the semantics of any of them, and there are several that sound like they could be what I need. So, if anybody knows how to exercise finer control over the Canvas postscript method, I'd be grateful to hear about it.

What does the above yield on Windows? Are inodes supported on Windows NTFS, FAT, FAT32?

Python - what is the fastest database ?
by martijn＠gamecreators.nl March 3, 2005

March 3, 2005

H!, I'm testing things with Python with databases. But I have one big question. What is the 'fastest' database for the internet in combination with Python ? - with +/- 15 GB data. - fast internet SELECT query's. Python use bsddb but could he handle 15 GB fast ? A other question is: How is it possible that google (super big database) is super fast? What type database do they use / software ? Thanks Very Much, GC-Martijn
