Hi!
frozenset() doesn't behave as the other immutable empty data types in 2.4:
..>>> '' is ''
True
..>>> () is ()
True
..>>> frozenset() is frozenset()
False

Sorry, bad title. Anyway, is there a way to pass the arguments to an object
instantiated via a constructor using the arguments object and have it
expanded, so to speak, so that it doesn't appear as a single argument? I'm
sorry, this explanation is just atrocious, but I can't think of exactly how
to word it. Maybe an example...
Take for instance Function.apply. It takes 1-2 arguments, the first being
the object to use as the context, and...

Hi,
Are there any benefits in using a frozenset over a set, other than it
being immutable?

I have released interval-0.2.1 at
http://members.cox.net/apoco/interval/. IntervalSet and
FrozenIntervalSet objects are now (as far as I can tell) functionality
equivalent to set and frozenset objects, except they can contain
intervals as well as discrete values.
Though I have my own unit tests for verifying this claim, I'd like to
run my code through actual set and frozenset unit tests. Does any such
code exist? Is it in pure...

Hi,
I've done some progress in writing a rather simple
singleton template.
However, I need a smart way to pass constructor arguments
via the template.
I've been suggested reading "Modern C++ Design" or similar
books, but I feel there are full of clever guys here
who could help me out.

I've got a class that I want to access remotely. The touble is, I can't
figure out how to call the constructor of the class with arguments -- and
the arguments are necessary to initialize the class.
For example, here's my code on the client end:
static void Main(string args)
{
HttpChannel chan = new HttpChannel(0);
ChannelServices.RegisterChannel(chan);

Hi,
I am getting an error while executing the following snippet. If i comment out method __repr__ , it works fine.

def __new__(cls, *data):
data = sorted(data)

When posting problems like this, please include the Python version.
If you ran this with 2.6, please run the following:
x = frozenset('abc')
y = frozenset('bcd')
z = x.difference(y)
print(id(x) != id(z))

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

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,...
