Hi all,
I was using Tkinter.IntVar() to store values from a large list of
parts that I pulled from a list. This is the code to initialize the
instances:
def initVariables(self):
self.e = IntVar()
for part, list in info.masterList.items():

I'd like to subclass int to support list access, treating the integer
as if it were a list of bits.
Assigning bits to particular indices involves changing the value of
the integer itself, but changing 'self' obviously just alters the
value of that local variable.
Is there some way for me to change the value of the BitSequence
object itself? I've also tried wrapping and delegating using
__getattr__, but I couldn't figure out how to handle...

First of all, please don't flame me immediately. I did browse archives
and didn't see any solution to my problem.
Assume I want to add a method to an object at runtime. Yes, to an
object, not a class - because changing a class would have global
effects and I want to alter a particular object only. The following
approach fails:
class kla:
x = 1

Hi Everyone,
I am having a problem with a class and hope you can help.
When I try to use the class listed below, I get the statement that self
is not defined.
test=TriggerMessage(data)
var = test.decode(self.qname)

The Python FAQ 1.4.5 gives 3 reasons for explicit self (condensed version):
1. Instance variables can be easily distinguished from local variables.
2. A method from a particular class can be called as
baseclass.methodname(self, <argument list>).
3. No need for declarations to disambiguate assignments to local/instance
variables.

Is there any trick to get rid of having to type the annoying,
character-eating "self." prefix everywhere in a class? Sometimes I
avoid OO just not to deal with its verbosity. In fact, I try to use
Ruby anywhere speed is not crucial especially for @ prefix is better-
looking than self.
But things grow -- is there any metaprogramming tricks or whatnot we
can throw on the self?
Cheers,

Hi,
I found one example which defines the addition of two vectors as a
method of a class. It looks like that:
class Vector:
def __add__(self, other):
data =
for j in range(len(self.data)):
data.append(self.data + other.data)

I am playing with some trees. In one of the procedures I wrote
for this I am trying to change self to a different tree. A tree
here has four members (val/type/left/right). I found that self = SS
does not work; I have to write self.val = SS.val and the same for
the other members (as shown below). Is there a better way to do this?
In the below self is part of a parse tree, F is the parse tree of a
function f with argument x. If a node...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
