Hi Group I'm trying to figure out a way that I can take two (two
dimensional) arrays and avShed and shed, and subtract the matching elements
in shed from avShed I've pasted the arrays blow from a print_r cmd any
suggestions would be great. Thanks much Todd
//avShed array
Array ( => Array ( => 1 => 08:00 ) => Array
( => 1 => 08:05 ) => Array ( => 1
=> 08:10 ) => Array ( => 1 => 08:15 )
=> Array ( => 1 => 08:20 ) => Array...

Hi,
Does anyone know if arrays would be picklable in python 2.4? Until
then, I tried to derive from array.array and add __setstate__ and
__getstate__ with the following code, but it seems I'm not doing it
correctly. Any idea what I'm doing wrong?
Thx and Regards,
Nicolas

Hello all,
I'm trying to subclass array.array but having problems with a default
parameter in the init constructor. Example:

Hi,
I have to do some data manipulation that needs to be fast. I had a
generator approach (that was faster than a list approch) which was
taking approximately 5 seconds to run both encode and decode.
I have done a conversion to pyrex and have gotten it down to about 2
seconds to run both encode and decode. An an excerpt from the pyrex
code is included below. My question is, is there a better way to
allocate the memory for the...

Googling for "pickle array" in comp.lang.python yields old messages that
show a PickleError -- plus one message where Alex Martelli writes "I am
but an egg" :O)
Looks like arrays are NOW (2.4.1) pickleable but not unpickleable -- see
below.
I appreciate that arrays are inherently not pickleable because of the
type code.
However:
(1) Anyone know why/when the world changed?
(2) If we had alternative constructors like...

I can declare and initialize a managed array of managed types like this:
System::Object* array __gc = {...}
Now, what do I do if I wanna reset that array to something else without
redeclaring it? I can't seem to just say something like
array = new __gc = {...}

Using MC++ .Net 2.0, with the CLR Profiler (from Microsoft) I am seeing
that 3 blocks of memory, each ~48MB in size, being allocated by some
code that initializes a managed array. It is a jagged array of string
arrays, and contains some nullptr items, sample code below. Looking at
the IL using .Net Reflector also below I think I see why.
This issue is easy to work around by using a gcnew array<String^{}
instead of a nullptr, but is not...

Hi All,
I have a question concerning the use of array.array inside of C++ code I
wrote.
I am working with _big_ data files but some entries in these files are
usually bounded say between -5 to 40. Returning a Python list makes no
sense. In Python I always work with the array.array module which does
the trick. But now that I wrote my own C++ module for some preprocessing
I need the return array.array objects.

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...
