I don’t know much about voting systems, but I know someone who does. Unfortunately he’s currently banned. Maybe we can wait until his 3-month ban expires and ask him for advice?

CircuitPython is an open-source implementation of the Python programming language for microcontroller boards. The project, which is sponsored by Adafruit Industries, is designed with new programmers in mind, but it also has many features that may be of interest to more-experienced developers. The recent 9.1.0 release adds a few minor features, but it follows just a few months after CircuitPython 9.0.0, which brings some more significant changes, including improved graphics and USB support.

CircuitPython is a fork of MicroPython (previously covered on LWN) with several changes designed to make the language easier for beginners to use. CircuitPython has a universal hardware API and is more compatible with the CPython standard library, for example. CircuitPython has some limitations compared to MicroPython, particularly with respect to concurrency, but is otherwise just as powerful.

...

This difference in APIs make sense when looking at the main goals of each project. MicroPython describes the language as ""a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments"". In contrast, Adafruit's "What is CircuitPython?" page says: ""CircuitPython is a programming language designed to simplify experimenting and learning to program on low-cost microcontroller boards."" Adafruit recommends CircuitPython for users who ""want to get up and running quickly"" or ""are new to programming"".

CircuitPython supports most of the core language features of CPython, although some features are missing due to the limited resources found on microcontroller boards compared to the much more powerful computers on which CPython typically runs. Many of those missing features will be the same as those on a comparison between CPython and MicroPython reports. In addition, as CircuitPython's main README explains: ""Modules with a CPython counterpart, such as time, os and random, are strict subsets of their CPython version. Therefore, code from CircuitPython is runnable on CPython but not necessarily the reverse.""

TL;DR: uv is an extremely fast Python package manager, written in Rust.

First thing first, while I started to build this package I've made an error with the word that I've misspelled in I'm not a native english speaker. I'm planning to change the name and correct it. So don't be mad with me about it. Ok now let me introduce my first python package.

aba-cli-scrapper** i'ts a cli tool to easily build a dataset from Alibaba.

look at the repo to know more about this project : https://github.com/poneoneo/Alibaba-CLI-Scraper

I'm excited to share the latest release of my first Python package, aba-cli-scrapper designed to facilitate data extraction from Alibaba. This command-line tool enables users to build a comprehensive dataset containing valuable information on products and suppliers associated . The extracted data can be stored in either a MySQL or SQLite database, with the option to convert it into CSV files from the SQLite file.

The latest feature will be an ai agent to chat with about data saved. I'm working on this. Its should be release very a soon.

Key Features:

--Asynchronous mode for faster scraping of page results using Bright-Data API key (configuration required)

--Synchronous mode available for users without an API key (note: proxy limitations may apply)

--Supports data storage in MySQL or SQLite databases

--Text mode for thoses who are not comfortable with cli app

--Converts data to CSV files from SQLite database

Seeking Feedback and Contributions:

I'd love to hear your thoughts on this project and encourage you to test it out. Your feedback and suggestions on the package's usefulness and potential evolution are invaluable. Future plans include adding a RAG feature to enhance database interactions.

Feel free to try out aba-cli-scrapper and share your experiences! Leave a start if you liked .

The Python Steering Council has decided to suspend a core Python developer for three months for alleged Code of Conduct violations.

Citing the recommendation of the Code of Conduct Working Group, Python developer Thomas Wouters revealed on behalf of the Steering Council that the unidentified developer was deemed to have repeatedly violated the Python Software Foundation (PSF) Code of Conduct.

The suspended developer is Tim Peters, who told The Register it was fine to name him but declined to comment – beyond observing that one of his objections to the governance process is the secrecy involved.

GIL or Global Interpreter Lock can be disabled in Python version 3.13. This is currently experimental.

Python 3.13 brings major new features compared to Python 3.12 and one of them is free-threaded mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently.

The GIL will be disabled when you configure the Python with the --disable-gil option which is nothing but a build configuration (free threading build) at the time of installation.

This will allow optionally enabling and disabling GIL using the environment variable PYTHON_GIL which can be set to 1 and 0 respectively.

It will also provide a command-line option -X gil which can also be set to 0 (disable) and 1 (enable).

Hi,

I use gunicorn in my venv

I have quite few venv that run gunicorn.

I would like to reuse gunicorn for other venv

I launch my web application like this

#PWD = venv dir
source ./bin/activate
gunicorn A_WebApp:app
#A_WebApp is my python file A_WebApp.py

I supposes that gunicorn is a shell program ? if yes I should use $PATH ?
or gunicorn is a Python program only ? and then what I should do to use gunicorn in another venv ?

Thanks.

Hi All,

I'm screening a large media library (20TB) wherein some files got corrupted when I did a transfer via filezilla (by my guess ~10%). The corrupted files display with a green "filter" over every frame (when played via plex and a number of local video players playing the file directly).

I'd like to screen the library, and want to write a script to get an average color reading.

Are there any libraries that would let me return a value AND specify how many frames I want it to take the average of? Because of how consistent and defined the issue is, it's really not necessary to average the whole file.

It would also be great if it automatically skipped non-video files, but I imagine a simple "try/except" would be fine.

My skill level here is best described as "high level hobbyist". I'm familiar with what I need to do iterating over the folder etc, but would prefer not to learn how to pull specific frames from a video container unless I have to.

Thanks for any help!

Hi,

I'm looking for a software similar to ZoneMinder
https://lemmy.ml/post/18530232

But it seem that ZoneMinder become slowly outdated, php etc..

I've found a couples of alternatives ( hard choice as the limitations of use are often buried deep )

It seem that openCV is really famous for AI Computer vision, So I would be surprise if there were no Python program to manage cameras like a ZoneMinder !?

Do you know any ?

Thanks.

New Ren'Py Lemmy Community!

Heyo, I made a community for Ren'Py developers to ask for help and share their projects! Feel free to tag it to crosspost your mastodon posts, just like this post here. (But read the rules first, please)

#RenPy #GameDev #VNDev #IndieDev #VisualNovel

Hello Python community! I wanted to present the newly-made Ren'Py community on here.

Ren'Py is a Python-based game engine for visual novel development aimed at beginner developers with little prior programming experience. It uses a simple movie script-like syntax and provides both must-have visual novel components and tons of quality-of-life features out of the box. Capable Python programmers can easily extend the framework via custom components.

If you ever wanted to create an interactive fiction game, feel free to take a look!

I wrote a TUI application to help you practice Python regular expressions. There are more than 100 exercises covering both the builtin re and third-party regex module.

If you have pipx, use pipx install regexexercises to install the app. See the repo for source code and other details.

Porting from Django+React to a Django+HTMX based stack

I have a repository that contains multiple programs:

.
└── Programs
    ├── program1
    │   └── Generic_named.py
    └── program2
        └── Generic_named.py

I would like to add testing to this repository.

I have attempted to do it like this:

.
├── Programs
│   ├── program1
│   │   └── Generic_named.py
│   └── program2
│       └── Generic_named.py
└── Tests
    ├── mock
    │   ├── 1
    │   │   └── custom_module.py
    │   └── 2
    │       └── custom_module.py
    ├── temp
    ├── test1.py
    └── test2.py

Where temp is a folder to store each program temporarily with mock versions of any required imports that can not be stored directly with the program.

Suppose we use a hello world example like this:

cat Programs/program1/Generic_named.py
import custom_module

def main():
    return custom_module.out()


cat Programs/program2/Generic_named.py
import custom_module

def main():
    return custom_module.out("Goodbye, World!")


cat Tests/mock/1/custom_module.py
def out():return "Hello, World!"


cat Tests/mock/2/custom_module.py
def out(x):return x

And I were to use these scripts to test it:

cat Tests/test1.py
import unittest
import os
import sys
import shutil

if os.path.exists('Tests/temp/1'):
    shutil.rmtree('Tests/temp/1')

shutil.copytree('Tests/mock/1', 'Tests/temp/1/')
shutil.copyfile('Programs/program1/Generic_named.py', 'Tests/temp/1/Generic_named.py')

sys.path.append('Tests/temp/1')
import Generic_named
sys.path.remove('Tests/temp/1')

class Test(unittest.TestCase):
    def test_case1(self):
            self.assertEqual(Generic_named.main(), "Hello, World!")

if __name__ == '__main__':
    unittest.main()



cat Tests/test2.py
import unittest
import os
import sys
import shutil

if os.path.exists('Tests/temp/2'):
    shutil.rmtree('Tests/temp/2')

shutil.copytree('Tests/mock/2', 'Tests/temp/2')
shutil.copyfile('Programs/program2/Generic_named.py', 'Tests/temp/2/Generic_named.py')

sys.path.append('Tests/temp/2')
import Generic_named
sys.path.remove('Tests/temp/2')

class Test(unittest.TestCase):
    def test_case1(self):
            self.assertEqual(Generic_named.main(), "Goodbye, World!")

if __name__ == '__main__':
    unittest.main()

Both tests pass when run individually:

python3 -m unittest Tests/test1.py
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK


python3 -m unittest Tests/test2.py
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK

However, they fail when being run together:

python3 -m unittest discover -p test*.py -s Tests/
.F
======================================================================
FAIL: test_case1 (test2.Test)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/s/Documents/Coding practice/2024/Test Mess/1/Tests/test2.py", line 18, in test_case1

AssertionError: 'Hello, World!' != 'Goodbye, World!'
- Hello, World!
+ Goodbye, World!


----------------------------------------------------------------------
Ran 2 tests in 0.001s

FAILED (failures=1)

If I try to use a different temporary name for one of the scripts I am trying to test,

cat Tests/test2.py
import unittest
import os
import sys
import shutil

if os.path.exists('Tests/temp/2'):
    shutil.rmtree('Tests/temp/2')

shutil.copytree('Tests/mock/2', 'Tests/temp/2')
shutil.copyfile('Programs/program2/Generic_named.py', 'Tests/temp/2/Generic_named1.py')

sys.path.append('Tests/temp/2')
import Generic_named1
sys.path.remove('Tests/temp/2')

class Test(unittest.TestCase):
    def test_case1(self):
            self.assertEqual(Generic_named1.main(), "Goodbye, World!")

if __name__ == '__main__':
    unittest.main()

Then I get a different error:

python3 -m unittest discover -p test*.py -s Tests/
.E
======================================================================
ERROR: test_case1 (test2.Test)

It seems to be trying to import the same file, despite me using a different file from a different path with the same name. This seems strange, as I've been making sure to undo any changes to the Python Path after importing what I wish to test. Is there any way to mock the path? I can't change the name of the custom_module, as that would require changing the programs I wish to test.

How should I write, approach, or setup these tests such that they can be tested with unittest discover the same as they can individually?
