Compress-py: A CLI to compress files with multiple algorithms
Hello there!
For some time now I've been working on a CLI that offers multiple algorithms to compress and decompress files, and I wanted to share it with you! Here is the Github repository
## What My Project Does:
Tl;DR: You compress stuff with it:
I have implemented Huffman Coding LZW, and RLE without any external compression library. Apart from those compression algorithms, I also implemented the Burrows-Wheeler Transform and Move-To-Front transform to increase compression efficiency.
My project allows you to combine these transformations with the main compression algorithm. If you're not sure which one to choose, I offer a compare-all command, which tests every compression algorithm on a file and provides useful information which will help you choose an algorithm.
Please read the README if you are curious about my implementation, I tried to articulate my choices as much as possible.
## Target Audience:
This was more of a toy project, and is certainly not supposed to be considered 'Production Level'. I wanted to immerse myself in the world of data compression, while refining my python skills.
With that being said, I think I achieved pretty good results, and anyone who wishes to take it for a spin for not-so-serious intentions is welcome.
## Comparison:

Recommended way to manage several installed versions of Python (macOS)
When I use VS Code and select a version of Python on macOS, I have the following versions:
* Python 3.12.8 ('3.12.8') \~/.pyenv/versions/3.12.8/bin/python
* Python 3.13.2 /opt/homebrew/bin/python
* Python 3.12.8 /usr/local/bin/python3
* Python 3.9.6 /Library/Developer/CommandLineTools/usr/bin/python3
* Python 3.9.6 /usr/bin/python3
I believe having this many versions of Python in different locations messes me up when trying to install packages (i.e. using brew vs pip3 vs pyenv), so I'm wondering what the best way is to clean this up and make package + version management easier?

I am learning Django and looking for open source project to read it's code and learn from it.
Is there any open source project based on Django so that one can clone and see the code just to learn how certain things are done? I am looking not just any project found in GitHub, I am looking for some good examples of Python/Django code, project organization and solutions to certain problems (like implementing MFA, extension of standard Django classes and etc.)

Project - StegH
I'd like to showcase a project I’ve been working on recently.
It’s an image steganography tool that allows you to hide messages inside images securely.
Key features of the tool include:
* **Encrypt & Hide Messages**: Securely hide secret messages inside image files using AES encryption.
* **Platform (Currently Windows-only)**: Right now, it’s available as an executable for Windows.
* **No external dependencies**: Pure Python with minimal libraries such as Pillow, NumPy, and pycryptodome.
**What my project does:** It enables users to securely encrypt and hide messages within images, allowing for private communication. The tool uses AES encryption to ensure the confidentiality of the embedded messages.
**Target audience:** This tool is intended for anyone interested in privacy, security, and steganography, especially developers and enthusiasts exploring encryption techniques.
**Comparison:** This tool isn’t just about encryption; it’s focused on embedding messages into images, which can be shared inconspicuously.
**One last thing:** Quick tip: When sharing an image with a hidden message, be sure to send it as a document (e.g., via WhatsApp's document sharing option). Sending it as a regular image might lead to compression, which could corrupt the hidden data.
Here’s the link to the GitHub repository: [Github](https://github.com/Soham-04/STEGH)
Would love to hear any feedback or thoughts on it!

Staticfiles on production server
So I’m trying to deploy my app to my server and is working except it looks ugly (no css, guess no js, etc) I’m ruining my app inside docker and an extra container with nginx. I setup a subdomain for my api and all works well. The api/docs documentation looks fine but the admin pages miss css,etc. I guess I need to hable staticfiles and add it to nginx but what is the way to go regarding this for production environment? Any tips will help. Many thanks

Do you use FastAPI on production?
I've read that FastAPI is used by some big companies, which by themselves have a lot of money and some of the best developers in the world. But down here on earth of poor people, are you (single dev or small company) using FastAPI on production?
It seems like FastAPI is largely developed and maintained by one person (Tiangolo). While he’s done an incredible job, this raises concerns about the project's long-term sustainability. With such a large user base, it’s surprising that there isn’t a bigger core team maintaining it. If Tiangolo were to step away, what happens to FastAPI?
It’s one of the most popular async-first frameworks, but relying on it in production sometimes feels like standing on shifting ground.
I’d love to hear from others working with FastAPI on production.

I wrote on post on why you should start using polars in 2025 based on personal experiences
There has been some discussions about pandas and polars on and off, I have been working in data analytics and machine learning for 8 years, most of the times I've been using python and pandas.
After trying polars in last year, I strongly suggest you to use polars in your next analytical projects, this post explains why.
tldr:
1. faster performance
2. no inplace=true and reset_index
3. better type system
I'm still very new to writing such technical post, English is also not my native language, please let me know if and how you think the content/tone/writing can be improved.

Easily share Python scripts with dependencies (uv + PEP 723)
Sharing single-file Python scripts with external dependencies can be challenging, especially when sharing with people who are less familiar with Python. I wrote a article that made the front page of HN last week on how to use uv and PEP 723 to embed external deps directly into scripts and accomplish the goal.
No more directly messing with virtual environments, requirements.txt, etc. for simple scripts. Perfect for sharing quick tools and utilities. uv rocks! Check it out here.

UPDATE safe-result 4.0: Better memory usage, chain operations, 100% test coverage
Hi Peeps,
The previous version introduced pattern matching and type guards.
## Target Audience
Anybody.
## Comparison
This new version takes everything one step further by reducing the Result class to a simple union type and employing __slots__ for reduced memory usage.
The automatic traceback capture has also been decoupled from Err and now works as a separate utility function.
Methods for transforming and chaining results were also added: map, map_async, and_then, and_then_async, and flatten.
I only ported from Rust's Result what I thought would make sense in the context of Python. Also, one of the main goals of this library has always been to be as lightweight as possible, while still providing all the necessary features to work safely and elegantly with errors.
As always, you can check the examples on the project's page.
Thank you again for your support and continuous feedback.

I built an open-source AI-powered library for web testing
Hey r/Python,
My name is Alex Rodionov and I'm a tech lead and Ruby (and a bit of Python) maintainer of the Selenium project. For the last few months, I’ve been working on Alumnium.
What My Project Does
It's an open-source Python library that automates testing for web applications by leveraging Selenium or Playwright, AI, and natural language commands.
Target Audience
Test automation engineers or anyone writing tests for web applications. It’s an early-stage project, not ready for production use in complex web applications.
Comparison
The closest project I am aware of is LaVague-QA, but it's a test generator (i.e. it generates Selenium+pytest tests from Gherkin specification), while Alumnium is just a library you can use in tests. It uses AI during test execution runtime to figure out Selenium interactions based on what's present in the browser.

Showcase A tarot reading app built in Python with Flask, SQL, and OpenAI — each reading is dynamic
What My Project Does
I built a pixel-art tarot app/game called Mama Nyah’s House of Tarot, where each reading is personalized, story-driven, and dynamically generated based on the user’s intention and cards drawn. Users enter an intention, pull three cards (past, present, future), and the app returns a poetic interpretation written by the OpenAI API.
The experience is meant to feel like stepping into a mystical little tarot parlor in New Orleans.
Target Audience
The project is built for people interested in tarot, storytelling, and immersive digital experiences. While not a full "game," it’s meant to offer a cozy, atmospheric escape or introspection tool. It’s available on Steam, but also served as a learning exercise for me to integrate a Flask backend, persistent user data, and API-driven storytelling.
How It Works / Stack
Python Arcade for game logic and UI
Python + Flask for the backend logic
Render to deploy the app, hold a token limiter, and store reading data
SQL to store user sessions and reading metadata
OpenAI API to generate fresh interpretations based on card combinations and intentions
Aseprite for creating all the pixel art assets
Comparison to Existing Alternatives
Most tarot apps use static card definitions or canned

How many SQL queries per request is too many when each includes SELECT, INSERT, and UPDATE?
I'm handling a backend where every API request triggers about 3–5 SQL queries a mix ofSELECT,INSERT, and UPDATE. These queries operate on individual objects and can't be batched, merged, or prefetched because each one serves a distinct purpose.
Is there a general rule of thumb on how many DB hits per request is too many before it becomes a performance concern?

yt-stats-wrangler - I Created a Python Package for collecting data from YouTube API V3
**What my project does:**
Hey everyone! I work with social media analytics and found myself sourcing data with YouTube API V3 quite often. After looking around for existing wrappers, I thought it would be a fun idea to make my own and deploy it as an open-source package.
So I'm introducing the **yt-stats-wrangler**, which is now available with a simple pip install (see install instructions on links below). Using a google developer key, the package quickly allows you to gather data from the YouTube Data API V3, and then output them into a specified format of your choice. This includes public data and stats on channels, videos and comments.
My goals were as follows:
* Create a modular package that can collect public YouTube data in a logical workflow
* Gather Channels -> Gather videos on channels -> Gather stats for videos -> Gather comments on videos
* Keep the package lightweight and avoid unnecessary dependencies, but offer optional integration of popular data libraries (pandas, polars) for ease of use
This is the first python package that I have ever released. I would love any feedback whether it be in technical implementation, or organizational/documentation structure. I've also attached an MIT license to the

Trying a Spring Boot style project structure in Django
I've been working with Django for the last 3–4 years. One thing I’ve always struggled with is keeping things clean and modular as the project grows.
Django’s flexibility is great, but I’ve often found myself mixing business logic in views, duplicating structure across apps, and losing track of where certain responsibilities live. So I’ve been trying a new approach lately borrowing ideas from Spring Boot (Java), which I used briefly and really liked for its structure.
What I tried:
Created a /apps/ directory where each app is treated as a self-contained module
Split responsibilities into:
controllers/ → class-based views
services/ → business logic
dtos/ → Pydantic v2 for request/response validation
Added a few management commands to generate apps + CRUD automatically:
python manage.py generateapp blog
python manage.py generatecrud blog Post
The goal is to keep things clean and explicit, especially for larger projects or when working with a team.
Here is Repo Link 🔗
It’s not trying to be a full framework, just a structured way to get up and running faster with good practices baked in. Eventual goal is to teach Django in meaningful way
Would love your thoughts on:
Is this too much structure for Django?
Does separating logic this way actually help in the long run?
What would you improve if you
