Pythons internal 'pointers' system is certainly causing me a few
headaches..... When I want to copy the contents of a variable I find
it impossible to know whether I've copied the contents *or* just
created a new pointer to the original value....
For example I wanted to initialize a list of empty lists....
a=, , , , ]
I thought there has to be a *really* easy way of doing it - after a

Does anyone here find the list comprehension syntax awkward?
I like it because it is an expression rather than a series of statements,
but it is a little harder to maintain it seems.
e.g. you could do:
result =
for element in list:
if element == 'blah':

Hi. I've made a program that logs onto a telnet server, enters a
command, and then creates a list of useful information out of the
information that is dumped to the screen as a result of the command.
Here's a generic version of the code in question:
#####
# Prior code opens telnet connection "tn" and logs in.
tn.read_until('> ')
tn.write('THE COMMAND IS HERE\n')

hello,
when i create list of lambdas:
l=]
then l() returns 'C', i think, it should be 'A'
my workaround is to define helper class with __call__ method:
class X:
def __init__(self,s): self.s=s
def __call__(self): return self.s.upper()

Sorry for a simple question- but I don't understand how to parse this use of
a list comprehension.
The "or" clauses are odd to me.
It also seems like it is being overly clever (?) in using a lc expression as
a for loop to drive the recursion.
Thanks for any insight!

Hi,
In a typical 3 tier model (view layer, busines layer and data access
layer) where do you handle your exceptions? do you let it buble up all
the way to the .aspx pages or do you handle it in your business layer
and/or data access layer?
suppose in my data access layer, I provide try and catch, log the
exception and re-throw it back to business layer, then in yoru business
layer, what do you do? throw it back to the code behind or...

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...
