Tiny Python library that turns functions into GUI apps
Hey! I made a small tool that lets you create GUI applications just by writing normal Python functions. It's inspired by FastAPI-Typer, but for desktop-mobile GUIs.
# Basic example:
from functogui import App, intUi, boolReturn
def iseven(number: int = intUi(4)) -> boolReturn:
return number % 2 == 0
App(iseven)
That's it - it creates a complete GUI with a slider and shows the result in real-time. Useful for quick tools and prototypes when you don't want to mess with UI code.
Built with Kivy, supports file handling, image preview, and different input types. Would love to hear your thoughts or suggestions!

How does the search algorithm work?
I am creating a web application in which registered users will have the opportunity to use a storage in which to store all their mp3 and wav files.
When they memorize them obviously they can listen to them and download them.
I created the user's song search system, so that he can individually select those that interest him more easily. The problem is that my system is very ugly: I take the user's input and check if the string he typed is inside the real_name column (of the file, file names stored in directories are changed to werkzeug.secure_filename) in the database and returns it.
Example: the user writes "I love" and if he presses enter the site returns "I love you.mp3", "I love him.wav", etc.
The problem is that a few small variations are enough to not give anything back.
Example: The user writes "I lo v," and the site returns nothing.
Is there an efficient algorithm?

WhiteNoise with Nginx for Django
I'm working on deploying a Django application, and I'm trying to figure out the best way to handle static files. Right now, I'm using WhiteNoise to serve static files.
My plan is to use Nginx as a reverse proxy for the Django app (running on Gunicorn) and also to serve static files. However, I'm not entirely sure how to configure Nginx to work alongside WhiteNoise.
1. Should I disable WhiteNoise entirely in production and let Nginx handle all static files?
2. If I keep WhiteNoise enabled, how should the Nginx configuration look?
3. Are there any pros/cons to using both together, or should I stick with one solution?

How to proxy to a flask/gunicorn app at a non-root location?
I have a flask app served by gunicorn that I want to proxy to through Apache (all on the same machine). I need the app to be accessible through `/wsgi` on the server.
So I'm trying this in the Apache config:
ProxyPass "/wsgi" "unix:/var/run/gunicorn/wsgi.sock|http://%{HTTP_HOST}"
This works but the problem is that `flask.url_for()` produces invalid urls because it doesn't know that it lives under `/wsgi`: It starts all generated URLs at `/` instead of `/wsgi`. It seems that I can make flask recognize this by setting the `SCRIPT_NAME` header like so:
<Location "/wsgi">
ProxyPass "unix:/var/run/gunicorn/wsgi.sock|http://%{HTTP_HOST}"
RequestHeader set SCRIPT_NAME /wsgi
</Location>
...but that doesn't work. `SCRIPT_NAME` remains set to the empty string in `flask.request.environ`.
How can this be done correctly? I don't want to do any hackery on the flask side of things (like hard-coding its "subdirectory" into the application).
Also I noticed that the `%{HTTP_HOST}` bit isn't expanded but gets passed as `%{http_host}` (lowercase) into `flask.request.environ`. Is this the intended behavior? I've got to admit that all my attempts so far have been more or less blindly copy-and-pasted from various web searches

I built my own PyTorch from scratch over the last 5 months in C and modern Python.
What My Project Does
Magnetron is a machine learning framework I built from scratch over the past 5 months in C and modern Python. It’s inspired by frameworks like PyTorch but designed for deeper understanding and experimentation. It supports core ML features like automatic differentiation, tensor operations, and computation graph building while being lightweight and modular (under 5k LOC).
Target Audience
Magnetron is intended for developers and researchers who want a transparent, low-level alternative to existing ML frameworks. It’s great for learning how ML frameworks work internally, experimenting with novel algorithms, or building custom features (feel free to hack).
Comparison
Magnetron differs from PyTorch and TensorFlow in several ways:
• It’s entirely designed and implemented by me, with minimal external dependencies.
• It offers a more modular and compact API tailored for both ease of use and low-level access.
• The focus is on understanding and innovation rather than polished production features.
Magnetron already supports CPU computation, automatic differentiation, and custom memory allocators. I’m currently implementing the CUDA backend, with plans to make it pip-installable soon.
Check it out here: GitHub Repo, X Post
Closing Note
Inspired by Feynman’s philosophy, “What I cannot create, I do not understand,” Magnetron is my way of understanding machine learning frameworks deeply. Feedback is greatly appreciated

Using Djando in a Full-Stack Application, I want your opinion!
Hello everyone, how are you?
I'm using Django to build a Full-Stack, Frontend and Backend application, using Bootstrap.
The application itself will be two,
1 - School Management System, where there will be everything a management system has.
2 - System for students to see posted classes
Basically, the two complement each other.
In a world where everything is Rest API and Frontend (Vue, React or Angular), building everything Full-Stack has become rarer, at least in my opinion.
Tell me, what are the pros and cons of this? Mainly I would like to hear from those who deal with applications like this on a daily basis and who tend to grow, any tips?
Thanks everyone!

I've created a tool to make json prettier ╰(°▽°)╯
Hey everyone,
I just added a JSON Beautifier to my website: https://javu.xyz/json\_beautifier
It takes messy JSON and turns it into nicely formatted, readable JSON. Plus, it has a key case conversion feature! You can select camelCase, snake\\\_case , PascalCase, or kebab-case and transform all keys.
I built this with JavaScript mostly and the Ace Editor library (man it's such a great lib). Ace Editor handles basic JSON syntax error highlighting like a boss.
Here's a peek at some key parts of the code cause i know somes are prob curious!! （￣︶￣）↗
`beautifyJSON()`: Grabs the JSON, reads your selected case preference and parses the JSON. If it's invalid, it will show an error message ( pop up windows )
`convertKeysToCase(obj, converter)`:This recursively goes through every key in the JSON object and applies the selected case conversion using helper functions: `toCamelCase`, `toSnakeCase`, `toPascalCase`, `toKebabCase`. These functions use simple string manipulation, like this:
```javascript
function toCamelCase(str) {
return str.replace(/[-_\]([a-z\])/g, (g) => g[1\].toUpperCase());
}
```
Nothing really fancy ahah (～￣▽￣)～
Then, `JSON.stringify` with `null, 4` pretty-prints with a 4-space indent.
Event Listeners: "Copy", "Paste", "Clear", "Example", and "Beautify" buttons do what you'd expect! \\\^o\^/
I also added a "Back Home" button that takes you back to the main page of my site.. LOL cause yeah i forgot that

Should PyPI allow 2 projects to have the same name for importing
In the install instructions for the ibis framework we read:
> the ibis-framework package is not the same as the ibis package in PyPI. These two libraries cannot coexist in the same Python environment, as they are both imported with the ibis module name.
1. What do you think of authors who knowingly build their package to "stomp" on a pre-existing namespace?

Chainmock - Mocking library for Python and pytest
I recently released v1.0 of a mocking library that I've been developing for a while. I use it in multiple projects myself and thought others might find it useful in their projects.
Github: https://github.com/ollipa/chainmock
Documentation: https://chainmock.readthedocs.io
What the project is:
Chainmock allows mocking, spying, and creating stubs. It's fully typed and works with unittest, doctest and, pytest. The syntax works especially well with pytest fixtures. Under the hood Chainmock uses Python standard library mocks providing an alternative syntax to create mocks and assertions. It also comes with some additional features to make mocking and testing easier.
Example:
mocker(Teapot).mock("brew").return_value("mocked").called_twice()
mocker(Teapot).spy("add_tea").any_call_with("green").call_count_at_most(2)

py2exe.com - flask app to convert python files to exe online
Hi,
I made a website (https://py2exe.com/) that compiles python to exe in the cloud. It could be useful for someone that wants to make .exe from python on linux, which is quite difficult to do.
The website is written in flask and the compilation is done via pyinstaller through wine. I would really appreciate it if someone could try it out with their project and share their thoughts.
The code is available on github (https://github.com/cenekp74/py2exe). I would love to hear your thoughts on my implementation of celery task queue or any other part of the flask app since I am not an expert and would love to improve.

Is my way of validating deletion forms inherently bad?
In a lot of places in the website I'm making, I need to make a button that sends the primary key of an object displayed in a list on the page to the server for it to do an action on the object like deleting it or incrementing the value of one of its fields. In those cases, I make a django form with a "type" and "object\_pk" hidden field.
In my view, I then loop on the queryset of every object I want to display in the list and append a dictionnary containing the object itself and its associated form to a list before passing it to the template as context. In this kind of situation, I can't just pass the form itself as context because its "object\_pk" field needs to have a different value for each object. I then display the submit button of each form to the user.
If the user comes to click on the button (let's say it's a delete button) the pk of the object is then sent to the same view which would resemble something like this:
def my_view(request):
if request.method == "POST" and request.POST["type"]

Tuitorial - I built a terminal-based tool for code presentations because PowerPoint was too painful
# What My Project Does
[Tuitorial](https://github.com/basnijholt/tuitorial) lets you create interactive code tutorials that run in your terminal. The key insight is that you define your code ONCE, then create multiple views highlighting different parts using pattern matching rules - no more copy-pasting code snippets across slides! Features include:
* Write code once, create multiple highlighted views
* Interactive step-by-step navigation
* Rich syntax highlighting
* Support for Markdown and even images
* Configure via Python or YAML
* Live reload for quick iterations
Here's a quick demo: [https://www.nijho.lt/post/tuitorial/tuitorial-0.4.0.mp4](https://www.nijho.lt/post/tuitorial/tuitorial-0.4.0.mp4) which runs [this YAML format presentation `pipefunc.yaml`](https://github.com/basnijholt/tuitorial/blob/main/examples/pipefunc.yaml)
# Target Audience
This is for the 0.1% of people who:
* Are giving technical presentations or workshops
* Love terminal-based tools
* Are tired of copying the same code into multiple PowerPoint slides
* Want version-controlled, reproducible tutorials
It's particularly useful for teaching scenarios where you want to focus attention on specific parts of code while keeping everything in context.
# Comparison to Existing Alternatives
The problem with traditional tools:
* PowerPoint/Google Slides: Forces you to copy-paste code multiple times just to highlight different parts
* Jupyter notebooks: Great for readers, but during presentations there's too much text for the audience to get distracted by
* Spiel: While also terminal-based, it's more for general presentations without code-specific features
* REPLs: Interactive but lack structured presentation

Potato - A Lightweight Tool for Debugging and Testing Python Code
# Potato: A Lightweight Tool for Debugging and Testing Python Code
# What is Potato?
Potato is a Python package designed to halt your code's execution with precision and simplicity. It’s perfect for debugging, testing control flow, or adding a bit of fun to your scripts. The best part? You don’t even have to install it. Python natively supports Potato, thanks to its strict variable naming rules.
Just type potato into your source code and watch the magic happen! Your script will immediately halt with a NameError, leaving your colleagues (or future self) wondering why there's a potato in your code.
# Why Potato?
Zero Dependencies: Potato requires absolutely no installations or updates.
Lightweight: Takes up 0 bytes of storage.
Instant Debugging: Clearly marks the exact point in your code where Potato strikes.
Fun for Everyone: Confuse your friends, co-workers, and even your future self with a well-placed potato!
# Installation
There is no installation. Python comes with Potato pre-installed. Simply open your favorite Python script and start typing potato.
# Usage
# Example 1: Halting a Script
print("Hello, world!")
potato
print("This will never run.")
Output:
Hello, world!

Guidance on python backend
Hi
I would appreciate some guidance on initial direction of a project I'm starting.
I am an engineer and have a good background in python for running scripts, calculations, API interactions, etc. I have a collection of engineering tools coded in python that I want to tidy up and build into a web app.
I've gone through a few simple 'hello' world flask tutorials and understand the very basics of flasm, but, I have a feeling like making this entirely in flask might be a bit limited? E.g I want a bit more than what html/CSS can provide. Things like interactive graphs and calculations, displaying greek letters, calculations, printing custom pdfs, drag-and-drop features, etc.
I read online how flask is used everywhere for things like netflix, Pinterest, etc, but presumably there is a flask back end with a front end in something else?
I am quite happy to learn a new programming language but don't want to go down the path of learning one that turns out to be right for me. Is it efficient to build this web app with python and flask running in the background (e.g to run calculations) but have a JS front end, such a vue.js? I would
