Have reasently upgraded to PySQLite 0.5.
I now have to "typecast" returned values to the "string expecting" GUI
widgets (wxPython).
Afrer reading the explanation, I'm still not clearer wich is better to
use... str() or repr()
example: self.wxTextCtrl.Setvalue( str(val))
## or repr(val)

Hello,
repr(0.1) is '0.10000000000000001', in my Python 2.3.
From reading the article "Floating Point Arithmetic: Issues and
Limitations", I understand that it's the closest 17-digit decimal
representation of the binary floating-point number actually stored.
However, I don't understand why this should be what repr of floats
returns. repr should, if possible, return a string that evaluating it
will be == to the original object. But...

Hi,
My application is receiving strings, representing windows paths, from
an external source. When using these paths, by for instance printing
them using str() (print path), the backslashes are naturally
interpreted as escape characters.
>>> print "d:\thedir"
d: hedir

I understand that idea of an object's __repr__ method is to return a
string representation that can then be eval()'d back to life, but it
seems to me that it doesn't always work.
For example it doesn't work for instances of the object class:
In : eval(repr(object()))
------------------------------------------------------------
File "<string>", line 1
<object object at 0xf233e8>

Was looking at PEP 3108, http://www.python.org/dev/peps/pep-3108/ ,
and saw that the repr module was slated for vaporization. I've only
used the module a few times ever. I'm curious if the community wants
it kept around or whether it is considered clutter.
The PEP is going to be finalized soon, so if you have issues with it,
they should be sent to the PEP author or brought up on the list,...

If answers here do not satisfy, the pydev list would be the place to
request that this change be put off until 3.0, when changes that break
are more permissible. I do not remember any discussion of this issue.
You can also post there via news.gmane.org/g.c.python.devel (the mail to

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
