Creating a framework for bots
by Schimon Jehudah March 21, 2025

March 21, 2025

Good day! My name is Schimon, and I create software in a form of XMPP contacts (i.e. bots) with chat and visual interfaces. https://git.xmpp-it.net/sch I already have three bots, and several ideas for other bots, including BitTorrent, MPD, and even Chess. gemini://woodpeckersnest.space/~schapps/journal/2024-05-23-slixfeed-news-bot.gmi https://schapps.woodpeckersnest.eu/journal/2024-05-23-slixfeed-news-bot/#pr… The basic structure of all of the bots is almost identical. Instead of repeating code and copy and paste my own templates, I was thinking of creating a framework for creating XMPP bots, based on the module Slixmpp, and perhaps also for IRC and MQTT. I do not know how to design a framework yet. I would appreciate guidance. Kind regards, Schimon

Python 3.14.0 alpha 6
by Hugo van Kemenade March 14, 2025

March 14, 2025

Here comes the penultimate alpha. https://www.python.org/downloads/release/python-3140a6/ This is an early developer preview of Python 3.14 Major new features of the 3.14 series, compared to 3.13: Python 3.14 is still in development. This release, 3.14.0a6, is the sixth of seven planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2025-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2025-07-22). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far: - PEP 649: deferred evaluation of annotations - PEP 741: Python configuration C API - PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers. - Improved error messages - A new type of interpreter. For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source. - UUID versions 6-8 are now supported by the uuid module, and generation of versions 3-5 and 8 are up to 40% faster. - Python removals and deprecations - C API removals and deprecations - (Hey, fellow core developer, if a feature you find important is missing from this list, let Hugo know.) The next pre-release of Python 3.14 will be the final alpha, 3.14.0a7, currently scheduled for 2025-04-08. More resources - Online documentation: https://docs.python.org/3.14/ - PEP 745, 3.14 Release Schedule: https://peps.python.org/pep-0745/ - Report bugs at https://github.com/python/cpython/issues - Help fund Python and its community: https://www.python.org/psf/donations/ And now for something completely different! March 14 is celebrated as pi day, because 3.14 is an approximation of π. The day is observed by eating pies (savoury and/or sweet) and celebrating π. The first pi day was organised by physicist and tinkerer Larry Shaw of the San Francisco Exploratorium in 1988. It is also the International Day of Mathematics and Albert Einstein’s birthday. Let’s all eat some pie, recite some π, install and test some py, and wish a happy birthday to Albert, Loren and all the other pi day children! Enjoy the new release Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organisation contributions to the Python Software Foundation. Regards from Helsinki as fresh snow falls, Your release team, Hugo van Kemenade Ned Deily Steve Dower Łukasz Langa

Yes, that's where a python.org install normally goes. If you are changing the system paths, that location is the one to use. But if that's the location that the system links Python.File to, it should launch without a problem. Maybe you should remove the path steps you added previously and see if that clears up the problem. First, though, try to run python using the absolute path you have just found. BTW, it's always a good idea to run pip using the python install that you will be running. So if "python" runs the right version, then invoke pip this way: python -m pip If you use the launcher, then: py -m pip This will make sure you use the version of pip that goes with your version of python, just in case there are other versions somewhere on the computer.

Is that an approved location for executables? May I know? What do you mean by approved location?

Hi Python community and members, I hope this email finds you well, I want you to be assisted in resolving this following issue. kindly look at the below concern, """I’m running into an error where I get a 'This app can’t run on your PC' pop-up with (Access is Denied error) whenever I try to run the Python version (python --version) or run python.exe in the Command Prompt on Windows 11.""" *Here’s what I’ve tried so far:* *Uninstalled python software from the apps settings and reinstalled python software from the official python.org site *Added Python to the PATH in the Environment Variables. (system variables, User variables.) ***C:\Users\Bharath\AppData\Local\Programs\Python\Python313\ ***C:\Users\Bharath\AppData\Local\Programs\Python\Python313\Scripts\ * however, then after I tried running direct path execution in the cmd. "C:\Users\Bharath\AppData\Local\Programs\Python\Python313\python.exe" --version, however it works well and it executed and showed the version, but without file path, it won't work anyway. * Additionally I've checked windows apps interference whether it is causing this error, and I saw a couple of python.exe files in this folder contains 0KB size then I thought these were corrupted and after I tried deleting these files, later I re-checked in cmd, however the issue persisted. refer to the following error for your further reference. *https://i.sstatic.net/6koOnZBM.png <https://i.sstatic.net/6koOnZBM.png>https://i.sstatic.net/65JC9FuB.png <https://i.sstatic.net/65JC9FuB.png>* * Ran the Command Prompt as an administrator. *Tried multiple other troubleshooting steps, but none of them worked. Despite these efforts, the issue persists. Could someone please help me resolve this? Extending my request you to kindly help me out of this error and give me the root cause of this problem. *Kind regards, * *Sincerely,* *Praveen Kumar* *Mob: *+91 9515531643
