PyPermission: A Python native RBAC authorization library!

Hello everyone at r/python!

At our company, we repeatedly needed to integrate authorization into Python projects and found the ecosystem a bit lacking.

# Comparison With Other Solutions

Django's permission system wasn't enough
Casbin, Keto and OPA offer flexible solutions, but can be hard to integrate
We wanted something Python-native, without a policy DSL and with auditing support

# What My Project Does

Knowing that authorization comes with many pitfalls, we decided to build an RBAC model focussing on an intuitive API and extensive testing. PyPermission is the result and draws on what we learned implementing RBAC across multiple projects (with and without third party solutions).

NIST RBAC Level 2a (supports general role hierarchies)
Framework independent, Free and Open Source
Additional capabilities from the ANSI RBAC model
A simple and tested python API
Persistency via PostgreSQL or Sqlite (SQLAlchemy)

# Target Audience

Developers looking for a simple authz solution without enterprise complexities, but a well established RBAC model.

The core implementation of the library is feature complete and heavily tested (overall test coverage of 97%) and we desire to have everything battle tested now. This is why we are excited to share our project with you and want to hear your feedback!

Is anyone else choosing not to use AI for programming?

For the time being, I have chosen not to use generative AI tools for programming, both at work and for hobby projects. I imagine that this puts me in the minority, but I'd love to hear from others who have a similar approach.

These are my main reasons for avoiding AI for the time being:

I imagine that, if I made AI a central component of my workflow, my own ability to write and debug code [might start to fade away](https://lucianonooijen.com/blog/why-i-stopped-using-ai-code-editors/). I think this risk outweighs the possible (but [not guaranteed](https://arxiv.org/pdf/2507.09089)) time-saving benefits of AI.
AI models might inadvertently spit out large copies of copyleft code; thus, if I incorporated these into my programs, I might then need to release the entire program under a similar copyleft license. This would be frustrating for hobby projects and a potential nightmare for professional ones.
I find the experience of writing my own code very fulfilling, and I imagine that using AI might take [some of that fulfillment away](https://colton.dev/blog/curing-your-ai-10x-engineer-imposter-syndrome/#its-okay-to-be-less-productive).
LLMs rely on huge amounts of human-generated code and text in order to produce their output. Thus, even if these tools become ubiquitous, I think there will always be a need (and demand) for programmers

I built a tool that converts your Python script into a shareable web app

I love writing simple Python scripts to fulfill niche tasks, but sharing them with less technical people always creates problems.

Comparison With Other Solutions

Sharing raw scripts leads to pip/dependency issues
Non-technical users often give up before even running the tool
The amazing tools our community develops never reach people who need them most
We needed something to bridge the gap between developers and end users

What My Project Does

I decided to build SimpleScript to make Python scripts accessible to everyone through beautiful, easy-to-use web interfaces. The platform automatically transforms your scripts into deployable web apps with minimal configuration.

Automatic script analysis and UI generation
Works with any Python script
Simple 3-step process: connect repo → auto-detect configs → deploy
Handles arguments, outputs, and user input automatically

Target Audience

Developers who want to share their Python tools with non-technical users without dealing with installation headaches or building full web applications.

I created my own Homehub in Python (D_Ei_Why_Hub)

Hey everyone,

(The link for the people who don't care about my yap)

([https://github.com/Grefendor/D\_Ei\_Why\_Hub](https://github.com/Grefendor/D_Ei_Why_Hub))

**What My Project Does:**

I used to always look for a project I can tackle to actually build something. So I started to build myself a pantry manager. This quickly escalated big time and now I have a fully modular homehub with different apps and widgets. There definetelly are still some errors every now and then. Specifically when it comes to the interface. It is intended to run on a tablet or like py with touchscreen and it will become more touch friendly in the future but for now there are some cool features:

\- it is multi lingual
\- it somewhat supports different resolutions (This will come I am just tired for today)
\-the pantry manager just needs a barcode and pulls the rest from the internet
\-there is homeassistant integration I have never tested, since I don't have home assistant (I really don't know why I did this, Dream big I guess)
\-A Taskboard
\-A simple calender and calendar widget
\-A clock (Revolutionary I know)

Planned features:
\- Spotify and Airplay integration (I have airplay speakers and want to use them via my

I built SentinelNav, a zero-dependency binary file visualization tool to map file structure

Hi everyone,

I’ve just released SentinelNav, a pure Python tool that creates interactive spectral maps of binary files to visualize their internal "geography." It runs entirely on the standard library (no pip install required).

What My Project Does

Analyzing raw binary files (forensics, reverse engineering, or file validation) is difficult because:

Hex Dumps are dense: Reading 50MB of hex code to find where a text section ends and an encrypted payload begins is mentally exhausting and slow.
Pattern Recognition: It is hard to distinguish between compressed data, random noise, and machine code just by looking at values.
Dependency Hell: Many existing visualization tools require heavy GUI frameworks (Qt) or complex environment setups just to perform a quick check.

The Solution: SentinelNav

I built a deterministic engine that transforms binary data into visual clusters:

Spectral Mapping: It maps byte values to RGB colors. High-bit bytes (compiled code/media) appear Red, printable ASCII appears Green, and nulls/padding appear Blue. This allows you to visually identify file headers and sections instantly.
Architecture Heuristics: It scans raw binary chunks to detect headers (PE, ELF, Mach-O) and attempts to guess the CPU architecture (x86 vs ARM64) based on instruction alignment and opcode frequency.
Entropy Analysis: It calculates Shannon entropy per block

Django cheat sheet for newbies (sort off): Tailwind, decorators, Auth, Nginx, Background tasks

There are some random things I do in Django, from setting up S3 storage to customizing the auth. Some concepts are basic, some not so much, so it's a mixed bag; maybe it'll be useful to you if you're learning Django or want to see some practical examples.

Built a small open-source tool (fasthook) to quickly create local webhook endpoints

I’ve been working on a lot of API integrations lately, and one thing that kept slowing me down was testing webhooks. Whenever I needed to see what an external service was sending to my endpoint, I had to set up a tunnel, open a dashboard, or mess with some configuration. Most of the time, I just wanted to see the raw request quickly so I could keep working.

So I ended up building a small Python tool called fasthook. The idea is really simple. You install it, run one command, and you instantly get a local webhook endpoint that shows you everything that hits it. No accounts, no external services, nothing complicated.

What should be the license of a library created by me using LLMs?

I have created a [plugin for mypy ](https://github.com/diegojromerolopez/mypy-pure)that checks the presence of "impure" functions (functions with side-effects) in user functions. I've leveraged the use of AI for it (mainly for the AST visitor part). The main issue is that there are some controversies about the potential use of copyrighted code in the learning datasets of the LLMs.

I've set the project to MIT license but I don't mind user other license, or even putting the code in public domain (it's just an experiment). I've also introduced a disclaimer about the use of LLMs in the project.

Here I have some questions:

* What do you do in this case? Avoid LLMs completely? Ask them about their sources of data? I'm based in Europe (Spain, concretely).
* Does PyPI have any policy about LLM-generated code?
* Would this be a handicap with respect to the adoption of a library?

app.run() not recommended for development server?

For me it would be convenient to run the Flask development server with Flask.run() however the documentation says:

> It is not recommended to use this function for development with automatic reloading as this is badly supported. Instead you should be using the flask command line script’s run support.

Documentation link: https://flask.palletsprojects.com/en/stable/api/#flask.Flask.run

Instead they suggest to use the command line flask run which I currently do.

But I wonder how its different. Why is Flask.run not recommended?

Do I need to remove WSGI_APPLICATION in settings.py ?

I just installed channels and in the docs I see ASGI\_APPLICATION but they never mentioned whether to remove
`WSGI_APPLICATION = 'myproject.wsgi.application'`

How does this settings affect production if I have only ASGI_APPLICATION variable. as I am planning to use **uvicorn** in production.

Advanced, Overlooked Python Typing

While quantitative research in software engineering is difficult to trust most of the time, some studies claim that type checking can reduce bugs by about 15% in Python. This post covers advanced typing features such as never types, type guards, concatenate, etc., that are often overlooked but can make a codebase more maintainable and easier to work with

I built a fast Advent of Code helper CLI for Python called elf


Hi all! With Advent of Code about to start, I wanted to share a tool I built to make the workflow smoother for Python users.

What My Project Does

elf is a command line tool that handles the repetitive parts of Advent of Code. It fetches your puzzle input and caches it, submits answers safely, and pulls private leaderboards. It uses Typer and Rich for a clean CLI and Pydantic models for structured data. The goal is to reduce boilerplate so you can focus on solving puzzles.

GitHub: https://github.com/cak/elf

PyPI: https://pypi.org/project/elf/

Target Audience

This tool is meant for anyone solving Advent of Code in Python. It is designed for day to day AoC usage. It aims to help both new participants and long time AoC users who want a smoother daily workflow.

Comparison

There are a few existing AoC helpers, but most require manual scripting or lack caching, leaderboard support, or guardrails for answer submission. elf focuses on being fast, simple, and safe to use every day during AoC. It emphasizes clear output, transparent caching, and a consistent interface.

If you try it out, I would love any feedback: bugs, ideas, missing features, anything. Hope it helps make Day 1 a little smoother for you.

Happy coding and good

context-async-sqlalchemy - The best way to use sqlalchemy in an async python application

Hello! I’d like to introduce my new library - **context-async-sqlalchemy**. It makes working with SQLAlchemy in asynchronous Python applications incredibly easy. The library requires minimal code for simple use cases, yet offers maximum flexibility for more complex scenarios.

What My Project Does: greatly simplifies integrating sqlalchemy into an asynchronous Python application

Target Audience: Backend developers, use in production or hobby or anywhere

Comparison: There are no competitors with this approach. A couple of examples in the text below demonstrate why the library is superior.


Let’s briefly review the theory behind SQLAlchemy - what it consists of and how it integrates into a Python application. We’ll explore some of the nuances and see how **context-async-sqlalchemy** helps you work with it more conveniently. Note that everything here refers to asynchronous Python.

# Short Summary of SQLAlchemy

SQLAlchemy provides an Engine, which manages the database connection pool, and a Session, through which SQL queries are executed. Each session uses a single connection that it obtains from the engine.

The engine should have a long lifespan to keep the connection pool active. Sessions, on the other hand, should be short-lived, returning their connections to the pool as quickly as possible.

# Integration and Usage in an Application

# Direct Usage

Let’s start with the simplest
