Python 2.3b2 is the second beta release of Python 2.3. There have be a slew of fixes since the first beta, and a few new "features". Our goal is to have a final Python 2.3 release by early August, so we encourage lots of testing for this beta.

I have a question about metaclasses: How would be the best way to "merge" different metaclasses? Or, more precisely, what is the best way to merge metaclass functionality? The idea is basicly the following: One has several (metaclass) modules that implements an interesting feature. Lets say, I have a metaclass L, that adds logging...

QOTW: "Giving full access rights to a secretary or new programmer ought to insure an occasional random file deletion." -- Raymond Hettinger "I always use join, but that's probably because that method is more likely to run code that I once wrote.

Hi, I'm trying to put an Tkinter.Entry of fixed size onto a specific location on a canvas using the place manager.

Some of the newsgroups in comp.lang have the auto-mailing facility where a program mails the first time poster in the newsgroup, a welcome mail with an brief introduction to the language and the newsgroup and useful web links for the language. I recently posted in comp.lang.tcl and received a rather large welcome mail detailing tcl and the...

Hello, Apologies if this seems like a trivial question, but it would help me with my python, coming from a Java background. What is the preferred naming convention for a .py file, that contains a class ? For example, if I have one class (MyClass), I wouldn't really want to put it in myclass.py, as I'd end up referencing myclass.MyClass...

hi, I am new to python (but not to programming - have programmed in many other languages like C++/lisp/perl etc.) and I would like to buy a good book.

Hi all, As a newly converted Python lover, I am impressed at how concise Python code actually is. But really... how concise can it GET? As an experiment to find out the very limits of Python, I'm generously offering a free smiley as well as my utmost and sincere admiration to whoever can come up with the shortest python module which can...

A colleague wants some functionality that I've built in a Python class available to 'drop' into her Visual C++ project. Some time ago she gave up on trying to use 'regular' COM servers, since ActiveX controls integrate so much more easily. So if I can't wrap the Python class into an ActiveX object, I'll have to port it. I've been...

Hi, The following small script has a child thread which restart the network on a Linux system. The problem is it never seems to return from the os.spawnlp.

Hi, I have been thinking about how to overload the assign operation '='. In many cases, I wanted to provide users of my packages a natural interface to the extended built-in types I created for them, but the assign operator is always forcing them to "type cast" or coerce the result when they do a simple assign for the purpose of setting the...

Hi, With the great unification of types and classes, what will happen to the following identity inconsistency? >>> class myint(int): pass .... >>> a=int(1); b=int(1) >>> a is b 1

Hi all, I can't get a py2exe compiled app to run with numarray (numarray-0.5.win32- py2.2). Also wxPythonWIN32-2.3.3.1-Py22 and ActivePython-2.2.1-222.
