Is it worth it to take Coursera course?
Did someone take the course
Programming for Everybody (Getting Started with Python) by University of Michigan?
Or what sources would you recommend for someone who doesn't particularly like Python however understands it's necessary to learn it? There are also some courses on Udemy, but I personally like Coursera better
Thanks!

Simple GUI directory contents extraction for chatbot submission
* **What My Project Does :**
A simple GUI tool that extracts a given directory structure and the contents of all its files then prints everything in an organized textbox + in an optional .txt file.
I made it to lazily submit entire projects to ChatGPT and let it "understand" their structure quickly.
* **Target Audience**
Anyone using chatgpt (or any llm chatbot) for writing or debugging code
* **Comparison**
There are probably better lightweight alternatives that I don't know about but this might be an easy to use alternative

The proposed method redefines the Evidence Lower Bound (ELBO) with a mixture of Gaussians for the posterior probability, introduces a regularization term to prevent variance collapse, and employs a PatchGAN discriminator to enhance texture realism. The main contribution in this work is an ELBO that reduces the collapse of the posterior towards the anterior (observed as the generation of very similar, blurry images)

Alternative to async/await without async/await for HTTP
asyncio is a great addition to our Python interpreters, and allowed us to exploit a single core full capabilities by never waiting needlessly for I/O.
This major feature came in the early days of Python 3, which was there to make for response latencies reaching a HTTP/1 server.
It is now possible to get the same performance as asyncio without asyncio, thanks to HTTP/2 onward. Thanks to a little thing called multiplexing.
While you may find HTTP/2 libraries out there, none of them allows you to actually leverage its perks.
The script executed in both context tries to fetch 65 times httpbingo.org/delay/1 (it should return a response after exactly ~1s)

How would you handle limits for Free Users without involving stripe?
I'm building the user functionality for my app and want to offer a free tier option with limited capabilities. What's the best way to implement usage restrictions for free users without involving payment processing?
The goals are to:
Allow free users to upload up to 3 photos per month and view up to 10 pages per day
Avoid requiring credit card information upfront, as that may deter signups
Track each free user's usage to enforce the limits
Some options I've considered:
Create a "Free" subscription plan with the desired limits, but set the price to $0. However, this would still prompt for a credit card which I want to avoid.
Add a "paid" boolean field directly to the User model. Set it to false for free users. Then track photo uploads and page views separately without involving subscriptions.
Have a UserUsage model that stores the user's monthly photo uploads and daily page views. Check this on upload/view attempts to enforce limits.
Do you have any other suggestions for tracking free user usage and limits without payment processing involved?

Advice Needed: Developing AI-Driven International Flight Planner for College Project – API Suggestions?
I’m working on my semester-end project, which is an AI-driven International Flight Planner. The goal is to help users find the best flight options tailored to their preferences (budget, airline, layovers, etc.), while also providing useful travel info like visa requirements, layover accommodation suggestions, and booking recommendations based on past pricing trends.
Would really appreciate any input on API selection, as well as any insights on tech stack choices for a project like this. Thanks in advance!
I’m using Django for the backend and considering PostgreSQL for storing flight data. However, I’m still looking into APIs that can provide reliable flight and travel data. I’m especially interested in APIs with a free tier or trial access since this is a college project.

5 months ago i asked which course to start django with ,now what's my next step ?
Greetings,
Five months ago, I created a post asking about how to start with Django. Months later, I completed a few courses, including a four-month ALX backend Django-focused course, and I made few basic API projects and few simple CRUD functionality projects using function-based views (FBV) and class-based views (CBV). Here’s one of my projects: https://github.com/Gamaljim/Fitness\_dj\_api (excuse the lack of a README or .gitignore file; I'm still learning how to properly set up a repo).
I'm 30 years old, stuck in a dead-end job in a country I don't want to be in, and I'm doing my best to study after work to shift my career and get back home as soon as possible. After finishing the course, I asked my instructor for feedback, and he said there’s still a lot to learn and that I’m not ready to apply for jobs yet. I understand this, but it did bring me down, and while I wouldn't say I'm depressed, I definitely feel low.
Now, to get to my question: What should I learn next? I've heard about CI/CD, Docker, Redis, and Celery, but these are foreign terms to me, and I don't know where and what to start with.
I hope you understand

FastStream: a powerful and easy-to-use library for building services with event streams
**FastStream** (https://github.com/airtai/faststream) simplifies the process of writing producers and consumers for message queues, handling all the parsing, networking and documentation generation automatically. It is a new package based on the ideas and experiences gained from **FastKafka** and **Propan**. By joining our forces, we picked up the best from both packages and created a unified way to write services capable of processing streamed data regardless of the underlying protocol. We'll continue to maintain both packages, but new development will be in this project.
Making streaming microservices has never been easier. Designed with junior developers in mind, **FastStream** simplifies your work while keeping the door open for more advanced use cases. Here's a look at the core features that make **FastStream** a go-to framework for modern, data-centric microservices.
Multiple Brokers: FastStream provides a unified API to work across multiple message brokers ([Apache Kafka](https://kafka.apache.org/), [RabbitMQ](https://www.rabbitmq.com/), [NATS](https://nats.io/) and [Redis](https://redis.io/))
**Pydantic Validation**: Leverage **Pydantic's** validation capabilities to serialize and validate incoming messages
[Automatic Docs](https://faststream.airt.ai/latest/getting-started/asyncapi/export/): Stay ahead with automatic [AsyncAPI](https://www.asyncapi.com/) documentation
Intuitive: Full-typed editor support makes your development experience smooth, catching errors before they reach runtime
[Powerful Dependency Injection System](https://faststream.airt.ai/latest/getting-started/dependencies/): Manage your service dependencies efficiently with FastStream's built-in DI system
**Testable**: Supports in-memory tests, making your CI/CD

Python pipeline flow visual scripting, auto-convert functions to nodes for fast, tweakable demos
I’m making a Python pipeline flow orchestration tool, a ML visual nodes system. It can automatically discover your functions as pipeline nodes. It can fast demo your python program for customers to tweak and expand. Visually pick input files, tune parameters, and preview any image input/output all in the friendly UI!
What My Project Does
Automatically discover python functions as nodes with parameters typing
Save/load pipeline as json and switch between pipelines quickly
Export the pipeline graph as Python code
Publish and install community node packages easily
GitHub: https://github.com/oozzy77/nozyio
Target Audience
Perfect for AI/ML engineers and designers to collaborate, turning ML components into UI nodes for easy tweaking. It's kinda like gradio but with modular and reusable interface blocks
Installation
In you python project, pip install nozyio then nozyio in your terminal and it will start the web UI.
Pypi: https://pypi.org/project/nozyio/
🎥video demo: https://www.youtube.com/watch?v=-bL3AcAufd8
I’m planning on porting some popular ML frameworks like huggingface’s transformers and diffusers into the node system so you can build AI generation pipelines visually. If you are interested in collaborating ✨, please do not hesitate to DM me!! Or email me at nozyio.hello@gmail.com

Copilot hallucinations wanted!
I am preparing a small introduction to github copilot for python for my students of a first year programming course. Of course, with this, there should also be a section on pitfalls. Are there any issues or hallucinations that you have encountered using github copilot?
For now the students have seen just the basics: looping (for and while), if-elif-else, string-methods, lists and user defined methods.
If you know any examples including any of these it would be very nice. Otherwise, examples from basic mathematical analysis, physics, chemistry or biology would also be nice.
I am already planning to make the fibonnaci sequence which it does recursively (very bad runtime).

I made a reactive programming library for Python
Hey all!
I recently published a reactive programming library called `signified`.
You can find it here:
* Source - https://github.com/dougmercer/signified/
* Docs - https://dougmercer.github.io/signified/
* PyPI - https://pypi.org/project/signified/
# What my project does
## What is reactive programming?
Good question!
The short answer is that it's a programming paradigm that focuses on reacting to change. When a reactive object changes, it notifies any objects observing it, which gives those objects the chance to update (which could in turn lead to them changing and notifying their observers...)
## Can I see some examples?
Sure!
### Example 1
from signified import Signal
a = Signal(3)
b = Signal(4)
c = (a ** 2 + b ** 2) ** 0.5
print(c) # <5>
a.value = 5
b.value = 12
print(c) # <13>
Here, `a` and `b` are Signals, which are reactive containers for values.
In `signified`, reactive values like Signals overload a lot of Python operators to make it easier to make reactive expressions using the operators you're already familiar with. Here, `c` is a reactive expression that is the solution to the pythagorean theorem (`a **

Beginner in Web Dev – Need Advice on Architecting a Website for a RAG System Chatbot (Using Flask/Python)
I’m building a simple chatbot website to deploy a Retrieval-Augmented Generation (RAG) system I’ve developed, and I need some advice on the architecture. The generator itself runs through an API, and my goal is to keep the setup efficient and fast. I’m experienced in ML but new to web development, so I’d love some pointers on how to structure this in a way that’s simple and effective.
If anyone has experience building a website for a RAG system, I’d love to hear about your architecture—especially how you set up and deployed the API for handling requests. Did you use something specific to optimize for speed and resource management? Any tips for handling responses and managing requests would be super helpful, especially for Flask/Python setups.

How to setup a permanent session in default Flask?
If I use Flask-Session to store session data server-side, it is as easy as passing SESSION_PERMANENT = False (not default Flask, unique to Flask-Session) to the app.config, then set the desired expiration time with , PERMANENT_SESSION_LIFETIME = desired_exp_time which is default Flask config.
If I use default Flask to store session data client-side, I need to set PERMANENT_SESSION_LIFETIME = desired_exp_time first, then state session.permanent = True in the request (ex. u/app.route), else I get this error: RuntimeError: Working outside of request context. The docs is somewhat unclear about how to implement, see here.
What I don't understand is how to setup the default Flask one. I tried to google, and found this in Stack Overflow. The accepted answer suggests setting it with before\_request, but I think why every request, we need to set session.permanent = True?
1. How to set permanent sessions in default flask properly? Where to set it?
2. Can you toggle permanent and non permanent session?
3. What should we do after session is expired? What about the session data?

Developing a Python-based Graphics Engine: Nirvana-3D
Hello community members,
[Crossposted from: https://www.reddit.com/r/gamedev/comments/1gdbazh/developing\_a\_pythonbased\_graphics\_engine\_nirvana3d/ \]
I'm currently working in GameDev and am currently reading and working on a 3D Graphics/Game Engine called: Nirvana 3D, a game engine totally written from top to bottom on Python that relies on NumPy Library for matrices and Matplotlib for rendering 3D scenes and imageio library for opening image files in the (R, G, B) format of matrices.
Nirvana is currently at a very nascent and experimental stage that supports importing *.obj files, basic lighting via sunlights, calculation of normals to the surface, z-buffer, and rendering 3D scenes. It additionally supports basic 3D transformations - such as rotation, scaling, translations, etc, with the support of multiple cameras and scenes in either of these three modes - wireframes, solid (lambert), lambertian shaders, etc.
While it has some basic support handling different 3D stuff, the Python code has started showing its limitations regarding speed - the rendering of a single frame takes up to 1-2 minutes on the CPU. While Python is a very basic, simple language, I wonder I'd have to port a large part of my code to GPUs or some Graphics Hardware languages like GLES/OpenCL/OpenGL/Vulcan or something.
I've planned the support for PBR shaders (Cook-Torrance Equation, with GGX approximations of Distribution and Geometry Functions) in solid mode as well as PBR shaders with HDRi lighting for texture-based image rendering and getting a
