Where can I get a python package to draw such figures? I googled and found PyX, I guess it outputs PostScript. I guess I can get a PostScript to BMP converter or something. Is there any other alternative? I have looked at PIL, but it doesn't seem to support drawing anti-aliased figures. Thanks for any suggestions. Andy

While I was coding a software which needs to set up a SSL transaction with a client using an underlying proprietary protocol, I found that the _ssl module works only in SSL client mode. Moreover it is impossible to write a select()-based polling algorithm with it since I can't query SSLObject for any available data in input (this occurs only...

I am a raw beginner to Python. I just read in "Learning Python" that assigning to a string argument inside a function does not change the string in the caller. I want an assignment in the function to alter the passed string in the caller. Is there any way to do this? For example def SafeAdd(self, Variable, Value): if self.form.has_key(...

Is there an HTML DOM parser available for Python? Preferably one that does a reasonable job with the crappy HTML out there on real web pages, that doesn't get upset about unterminated tables and stuff like that. Many extra points if it understands Javascript. Application is a screen scraping web robot. Thanks.

Hi, I think I found a bug in the write method of file objects. It seems as if before writing each block, a check was done in order to verifiy that there is enough space left for the *whole* file, not for the *remaining* data to be written. It happens both under 2.3 and 2.2.3. Any ideas?

Hello All, I have a frame that contains a panel and several buttons. I'd like to make one of the button the default button but self.SetDefaultItem(btn) or btn.SetFocus() don't work. The item in focus is a text control inside the panel. Any Ideas? (see short example below) Thanks.

I just installed Python 2.3 on my Redhat system. When I tried to run one of my programs that use tkFileDialog.askopenfilename(), I got an error because it returns a tuple instead of a null string when I select Cancel.

Hi, I am looking for a good plotting package (preferably with 3D plotting capabilities) based on Python 2.3 (Windows 98). Unfortunately Dislin does not exist for Python 2.3. I look forward to suggestions from members. Regards, Srijit

It will contain many of the features of this year's successful conference, including a development sprint and a similar cost structure. Registration will be open by October 1. A Call For Proposals will be...

Hi, I would like to use the Python C API to use python to access functions originally written in C. The objects that I would like to pass to python have multi-dimensional arrays. How do I include arrays as object member? And how is it declared in the PyMemberDef array? If you can not use C arrays, I thought perhaps then I should use...

I am a just a dabbler in programming, but I'd like to make some simple cross-platform tools for generating webpages, as well as for text munging. One thing I need is a Mac OS 9/Windows GUI solution. I thought that Tkinter could provide this, but I'm having trouble getting the simple test script from Learning Python p.22 to work under Mac...

Hi, I posted a while ago for some help with my word finder program, which is now quite a lot faster than I could manage. Thanks to all who helped :) This time, I've written a basic batch binary usenet poster in Python, but encoding the data into yEnc format is fairly slow. Is it possible to improve the routine any, WITHOUT using...

The pychecker site says that pychecker works with versions 1.5 through 2.2. Any reason to expect that 2.3 breaks it? Anyone tried it to see? TIA Al

Hi all, I'm starting a new project to develop an Open-Source EAI server in Python and I'm looking for motivated developpers and testers. It is inspired by Open Adaptor (www.openadaptor.org), but aims to be easier to use and more powerful. I've developped yet a first alpha that contains several components: File Source

I'm tryinh to switch from mx.tidy to uTidyLin and it isn't going well. So far I can't even import TidyLib. Below is what I get when trying to import into Idle.

Python Gurus, Is it possible to write python WMI event consumer using event handler rather than polling WMI? I got the equivalent C# code snippet from http://www.ondotnet.com/pub/a/dotnet/2003/04/07/wmi.html using System;

Bonjour ! J'ai publié dans "announce", mais, comme cela n'apparaît pas (???), je donne l'adresse ici : http://mclaveau.com/ress/python/zipmci.htm Dans ce gros exemple, il y a, notamment, la suppression des fichiers, la réaffectation des date-time des fichiers extraits, etc. @-salutations

In Python 2.3 there is a new library for handling tarfiles. However, there doesn't seem to be any documentation on handling end-of-tape conditions. I've googled for it and checked the docs, I've even looked into the modules src and all I found was an end of file exception that might do what I'm looking for, but might not. Anyone have any...

Hi, having had a number of problems with PyRun_File in my application embedding Python, I decided to load scripts into memory myself and execute them with PyRun_(Simple)String. This works fine and dandy except for when scripts reach a certain size. Around the 28000'th byte, it seems to break up the script, resulting in random errors caused...

I'm doing some native code stuff and want to pass continguos memory blocks of data back and forth between Python and C, with the memory blocks modifiable in both realms. What is a good way to do that? As I understand it, "buffer interface" objects (e.g. strings or arrays) won't work because memory is not guaranteed to be continguous. Tim
