Anyway...
At Europython Guido discussed with everyone the outstanding issue with
decorators and there was a clear majority in favour of having them, which
was good. From where I was sitting it looked like about 20:20 split on the
following syntaxes:
1 def func(arg1, arg2, arg3) :
function...
2 def func(arg1, arg2, arg3):

For what it's worth:
As far as I know, the proposed @decorator syntax will be the first
time that two logical lines of python with the same indentation will
not be independent of one another. Previously, when looking at:
some_python(code)
and_some_more = stuff
there was no need to look at the the first line in order to know what

Decorators can generate endless debate about syntax, but can also
be put to better use ;)
Actually I was waiting for decorators to play a few tricks that were
syntactically too ugly to be even imaginable for Python 2.3.
One trick is to use decorators to implement multimethods. A while ago
Howard Stearns posted here a recipe to implement generic functions
a.k.a multimethods.

I've been following the decorator debate with some interest, and it's taken
me a reasonably long time to understand what is meant by a decorator. One
of the issues is that the Decorator pattern is more like a Unix pipe than
it is what PEP 318 calls a decorator. The classic decorator is run-time,
rather than define time, and is non-destructive to the base function. The
PEP 318 decorator is define time and is a destructive change to the base...

Robert and Python-dev,
I've read the J2 proposal up and down several times, pondered all the
issues, and slept on it for a night, and I still don't like it enough
to accept it. The only reason to accept it would be to pacify the
supporters of the proposal, and that just isn't a good enough reason
in language design.
However, it got pretty darn close! I'm impressed with how the
community managed to pull together and face the enormous...

Here is a hack to implement attribute access (say for a Web framework)
the way I always wanted it to be. I say "hack" since it uses sys._getframe
and it sets the locals of a class, which is not recommended. Still, it seems
to work. I post the recipe here since since I would like to know if
1. it really works;
2. if yes, is there a chance that it will not work in future versions of Python;
3. will it work under Jython?
Even if it turns...

Would it not be nice if you could assign decorators to attributes too ?
for example
class C:
@staticattribute
data='hello'
or

Hi,
are decorators more than just syntactic sugar in python 2.x and what
about python 3k ?
How can I find out the predefined decorators?
Many thanks for your help,

Probably a bit of weird question. I realise decorators shouldn't be
executed until the function they are defined with are called, but is
there anyway for me to find all the decorates declared in a file when
I import it? Or perhaps anyway to find the decorators by loading the
file by other methods (with out simply parsing it by hand).
Basically what I'm looking for is a way to, given a python file, look
through that file and find all the...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
