Peter Norvig's creative thinking triggered renewed interest in PEP 289.
That led to a number of contributors helping to re-work the pep details
into a form that has been well received on the python-dev list:
http://www.python.org/peps/pep-0289.html
In brief, the PEP proposes a list comprehension style syntax for
creating fast, memory efficient generator expressions on the fly:
sum(x*x for x in roots)

I'm working on the 0.8 release of my 'rex' module, and would appreciate
feedback, suggestions, and criticism as I work towards finalizing the
API and feature sets. rex is a module intended to make regular expressions
easier to create and use (and in my experience as a regular expression
user, it makes them MUCH easier to create and use.)
I'm still working on formal documentation, and in any case, such
documentation isn't necessarily the...

I wrote a parser to solve math expressions like "3.0 ^(4 - 5)", or "3 / 8".
Below my sig is recursiveDescentParser.cpp, the test suite that drove the

Test-Driven Development works by accumulating assertions. Before the very

Folks,
I've started using regular expressions for parsing some data string
that come along - works quite nicely, however, as a newbie to RE, I'm
still struggling with some special cases:
1) I get strings representing decimal values, and they have the
following format:
* first, a plus or minus sign
* then, a number of numeric chars

Hey all,
I want to create my own XML parser that is completely independent of
PHP version (i want it to run on both PHP 4 and 5), and to also not
require any dependencies (so that the user DOESN'T have to compile php
with --with-xml).
Can someone point me in the right direction as to how I can go about
this?

Hi,
before I rack my brain about something others have thought about, here
my question:
Is there any description how to write a parser that evaluates
expressions with logical operators like "(condition1 OR condition2 AND
(condition3 OR condition4))" in the right way?
Best regards,

What's the way to go about learning Python's regular expressions? I feel

I'm kind of disappointed with the re regular expressions module. In
particular, the lack of support for recursion ( (?R) or (?n) ) is a
major drawback to me. There are so many great things that can be
accomplished with regular expressions this way, such as validating a
mathematical expression or parsing a language with nested parens,
quoting or expressions.
Another feature I'm missing is once-only subpatterns and possessive
quantifiers...

I am approaching parsing for the first time and I can't find which solution is best for me.
I need to process command line strings implementing mathematical operations (defined by me) on objects (defined by me), i.e.
Prompt:> ((A*B)->C)+2
A,B,C could be matrixes or more complex objects
*, -> ,+ could be operations which I want to implement
Is there a parser approach most suitable for this?

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...

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.
