Hi,
What's the syntax to add an attribute to a function form the function body?
For example, instead of doing:
def fn():
return 1
fn.error = "Error message"
print fn.error

I'd like to write a Tkinter app which, given a class, pops up a
window(s) with fields for each "attribute" of that class. The user could
enter values for the attributes and on closing the window would be
returned an instance of the class. The actual application I'm interested
in writing would either have simple type attributes (int, string, etc.),
or attributes using types already defined in a c-extension, although I'd
prefer not to...

After working through a fair number of the challenges at
www.mathschallenge.net, I noticed that some long-running functions can
be helped *a lot* by caching their function results and retrieving from
cache instead of calculating again. This means that often I can use a
natural recursive implementation instead of unwinding the recursive
calls to avoid big exponential running-times.
Ok, so I thought, how about creating a decorator that...

Hello
Could anyone please explain how I can pass more than one
arguement/parameter value to a function using <asp:linkbutton> or is
this a major shortfall of the language ?
Consider the following code fragments in which I want to list through
all files on a directory with a link to download each file by passing
a filename and whether or not to force the download dialog box to
appear.

Is it possible to determine a method's own attributes from within the method
without hardcoding the name of the method as a constant within the method?
Please tell me if it is possible and how it is done.
Thank you,

I got a puzzler for y'all. I want to allow the editing of functions
in-place. I won't go into the reason (it's for HTConsole --
http://blog.ianbicking.org/introducing-htconsole.html), except that I
really want to edit it all in-process and in-memory. So I want the
identity of the function to remain the same, even as I edit the body
and hopefully the signature too.
Well, the reason is that I want to edit any function object, without...

Hi,
Sorry in advance, english is not my main language :/
I'd like to customize the result obtained by getattr on an object : if
the object has the requested property then return it BUT if the object
doesn't has actually this property return something else.
In my case, I can't use getattr(object, property, default_value).

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,...

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...

Hello
I'm a network technician in training and I need your help.
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...
