Dr. Dobb's Python-URL! - weekly Python news and links (Jul 7)

QOTW: "Confrontin g the Martellibot is like flirting with an encyclopedia,
I'd rather not do it myself, but I respect those who do, because it
produces knowledge." -- Anton Vredegoor

"Python and Java are not diametrically opposed religions that must fight
to the death in jihad, despite the existence of loonies favoring exactly
that. They solve different problems; sometimes in similar ways, sometimes
not." -- Mark Hughes
Discussion
----------
Michael Chermside explains what assignment in Python means, and how
this conflicts with a proposed change of the assignment 'operator'.
<http://groups.google.c om/gr************* *************** *************** ******@python.o rg>

Bengt Richter adds another twist to this discussion about overloading
the assignment operator (which is a statement, really).
<http://groups.google.c om/gr************* ************@21 6.39.172.122>

Geoff Howland discusses issues related to the use of Python
executables for source code secrecy, instead of speed increase.
<http://groups.google.c om/gr************* *************** *************** ****@4ax.com>

Erik Max Francis explains the difference in output of printing an
element as part of a list and printing the element itself.
<http://groups.google.c om/gr************* *************** **@alcyone.com>

Mirko Zeibig shows that "bound method" objects can be used for
callback functions, or "functors".
<http://groups.google.c om/gr************* *************** ***********@zei big.net>

Erwin Andreasen explains that buffering is why a python script with
multiple threads can seem to execute the same 'print' multiple times.
<http://groups.google.c om/gr************* **************@ andreasen.org>

David Bolen adds insight to the question "when is unit-testing bad?",
regarding elements that we think are hard to unit-test.
<http://groups.google.c om/gr************* *************@f itlinxx.com>

Bengt Richter shows how to use zip to transpose a list to get a
list of columns (apparently inspired by a Martellibot post).
<http://groups.google.c om/gr************* ************@21 6.39.172.122>

Tkinspect is a kind of debugger that allows one to diagnose a Tkinter
process "from the outside".

You learn something new every day: On my ubuntu, update-manager is supposed to use the python2.5 installed on /usr/bin. Well, I had subsequently installed a whole bunch of stuff in /usr/local (/usr/local/bin/python and /usr/local/lib/ python2.5 etc), which I have happily been using for development for a year. I had thought that the two pythons were completely independent. Well, I was wrong. When /usr/bin/python2.5 runs, *by default*,...

Hi, Sorry I've posted a similar question some weeks ago, but I got no answers. I want to embed a Python application on a device with limited resources, esp. storage limitations. Is there a way to reduce the Python interpreter to a set of modules that's urgently needed? Or is there a method to have gzipped modules that are unzipped on the fly into memory when they're accessed? That would be even better. Additionally, is there a Python...

Hi there, This is my first post over here and I hope someone can give me some guidance. I'm trying to embed Python into a Visual C++ 2008 application and I'm getting linker problems. I've compiled a DLL of the Python source code using the pythoncode VC++ project in the PCbuild folder of the source download and this works 100% without any warnings etc. I've done this in Debug and Release mode without any problems.

Hi everyone, I'm a big Python fan who used to be involved semi regularly in comp.lang.python (lots of lurking, occasional posting) but kind of trailed off a bit.

This is not flamebait. I love Python, and I'm not out to antagonise the community. I also...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
