django-components v0.135 - Defaults, Vue-like class and style attributes, and extensions
Hey, I haven't shared updates on django-components in some time (last was on v0.122). Lots of new things! Some highlights:
\- Extensions \- Hook into component lifecycle, pre-/post-process components, add custom URLs, or custom commands.
\- Performance improvements (see 0.128 and 0.126) - 5x perf gain with Rust. Components can now be infinitely nested. Also, we now actively track performance of each release, see here. The aim is to get it to at least as fast as vanilla Django templates.
\- Add defaults to your components.
\- The {% html\_attrs %} tag allows you to manage class and style attributes with same granularity as seen in Vue.
\- Tests for your components are now easy to write with \``@djc_test`\` decorator. It ensures that all the internal state is reset after the test is done.
\- More debugging tools, such as to highlight components and / or slots in the UI
\- When using template tags from django-components, like `{% component %}`, our tags have extra nicities, such as allowing you to define literal lists and dictionaries when writing an input for a component. You too can write template tags with these extra features, with \``@template_tag`\` decorator, or by subclassing from \``BaseNode`\`

Remote control with terminal client
Hi, created Python packages indipydriver and indipyterm which provide classes to interface with your own Python code controlling instruments, GPIO pins etc., and serves this data on a port. Indipyterm creates a terminal client which can then view and control the instrument, useful for headless raspberry pis or similar devices. Available on Pypi, and more info at

PyAwaitable 2.0.0 Released - Call Asynchronous Code From An Extension Module
Hi everyone! I've released PyAwaitable with a major version bump to 2. I completely redesigned how it's distributed, so now it's solely a build time dependency; PyAwaitable doesn't have to be installed at runtime in your C extensions, making it extremely portable.
## What My Project Does
PyAwaitable is a library for using async/await with extension modules. Python's C API doesn't provide this by default, so PyAwaitable is pretty much the next best thing!
Anyways, in the past, basically all asynchronous functions have had to be implemented in pure-Python, or use some transpiler like Cython to generate a coroutine object at build time. In general, you can't just write a C function that can be used with await at a Python level.
PyAwaitable lets you break that barrier; C extensions, without any additional transpilation step, can use PyAwaitable to very easily use async/await natively.
## Target audience
I'm targetting anyone who develops C extensions, or anyone who maintains transpilers for C extensions looking to add/improve asynchronous support (for example, mypyc).
## Comparison
There basically isn't any other library like PyAwaitable that I know of. If you look up anything along the lines of "Using async in Python's C API," you get led to some of my DPO threads

the backend doesn't support altering from IntegerField to AutoField.
Hello everybody.
I'm having issues with my models.py. I inherited a codebase from a few years ago which uses varios IntegerFields for its Primary Key.
At first it was fine but later on it started causing issues where it won't save rows properly, making me want to change the field to an Autofield as it should have been.
I'm using MSSQL where I can't alter into Autofields. I found a workaround where I delete the column from the id for 1 migration and recreate it, but it is very clunky as it deletes the values from the db and if the column is used as a foreign key elsewhere it becomes even clunkier to delete.
Wanted to know if anyone has any advice on how to more efficiently work around this. Preferably without deleting itema from the db.

D Why is table extraction still not solved by modern multimodal models?
There is a lot of hype around multimodal models, such as Qwen 2.5 VL or Omni, GOT, SmolDocling, etc. I would like to know if others made a similar experience in practice: While they can do impressive things, they still struggle with table extraction, in cases which are straight-forward for humans.
Attached is a simple example, all I need is a reconstruction of the table as a flat CSV, preserving empty all empty cells correctly. Which open source model is able to do that?

I made airDrop2 with 3.11.3 and Flask.
What My Project Does:
iLocalShare is a simple, no-frills local file-sharing server built with Python 3.11.3 and Flask. It lets you share files between Windows and iOS devices using just a browser—no extra apps needed. It works in two modes: open access (no password) or secure (password-protected).
Target Audience:
This project is perfect for anyone who needs to quickly transfer files between their PC and iOS device without using Apple’s tools or dealing with clunky cloud services. It’s not meant for production environments, but it’s a great quick and dirty solution for personal use.
Comparison:
Unlike AirDrop, iLocalShare doesn't require any additional apps or device-specific software. It’s a lightweight solution that uses your local network, meaning it won’t rely on Apple’s ecosystem. Plus, it’s open-source, so you can tweak it as you like.

I built xlwings Lite as an alternative to Python in Excel
Hi all! I've previously written about why I wasn't a big fan of Microsoft's "Python in Excel" solution for using Python with Excel, see the [Reddit discussion](https://www.reddit.com/r/Python/comments/1de2hkw/my_thoughts_on_python_in_excel). Instead of just complaining, I have now published the "xlwings Lite" add-in, which you can install for free for both personal and commercial use via [Excel's add-in store](https://appsource.microsoft.com/en-us/product/office/wa200008175?tab=overview). I have made a [video walkthrough](https://youtu.be/amCCEbJ39W8?si=3vmVEZUr6RA0-IgS), or you can check out the [documentation](https://lite.xlwings.org/).
xlwings Lite allows analysts, engineers, and other advanced Excel users to program their custom functions ("UDFs") and automation scripts ("macros") in Python instead of VBA. Unlike the classic [open-source xlwings](https://github.com/xlwings/xlwings), it does not require a local Python installation and stores the Python code inside Excel for easy distribution. So the only requirement is to have the xlwings Lite add-in installed.
So what are the main differences from Microsoft's Python in Excel (PiE) solution?
* PiE runs in the cloud, xlwings Lite runs locally (via Pyodide/WebAssembly), respecting your privacy
* PiE has no access to the excel object model, xlwings Lite does have access, allowing you to insert new sheets, format data as an Excel table, set the color of a cell, etc.
* PiE turns Excel cells into Jupyter notebook cells and introduces a left to right and top to bottom

Building a car service website
Hey everyone,
I’m building a Django app for a car booking service, and I’m trying to design a clean reservation + payment flow that’s flexible and user-friendly.
What I have:
• A Reservation model that holds all key info (vehicle, route, customer, pricing, status, etc.)
• A Rate model that links a vehicle and route (each with one-way and round-trip prices)
• When a user browses the site, they see route/vehicle combinations with prices
What I want to build:
• When a user clicks “Book Now” next to a specific rate (say, SUV from Airport to Hotel):
• They’re taken to a pre-filled reservation form with that vehicle and rate
• They fill in customer info, passenger count, special requests, flight info, etc.
• After submitting, they choose to either:
• Pay now via Stripe
• Save their card and pay later
I’m not using Stripe Checkout directly. Everything is tied to the Reservation object first, and then payment is triggered.
What I’m stuck on:
• What’s the best pattern for pre-filling the reservation form with a specific rate? I did a request.GET.get(‘vehicle_type’) and same for route and rate to get this information but i feel theres a better way
Is there a good way to cleanly separate form logic from payment logic without overcomplicating views?
How should I handle the “save card for later”

What is the best website to deploy a flask app in 2025
Hey, I'm ready to deploy my first flask app and I'm looking for the best way to deploy it. Do you guys have recommendations for the best/cheapest/simplest way to deploy it in 2025. Here's some specifications about my project:
My website is relatively simple and mostly does requests to public APIs.
I'm expecting about 500-1000 visits per day, but the traffic might grow.
I have a custom domain, so the server provider needs to allow it (PythonAnywhere's free tier won't work).
I'm willing to spend a few dollar (maybe up to 30) per month to host it
I've heard of Pythonanywhere, Vercel, Render and Digitalocean, but I would like to have some of your opinions before I chose one. Also, I'm worried about waking up one day and realizing that someone spammed my website with a bot and caused a crazy bill. So, I was also wondering if some of these hosting providers had built-in protection against that. Thanks!

I benchmarked Python's top HTTP clients (requests, httpx, aiohttp, etc.) and open sourced it
Hey folks
I’ve been working on a Python-heavy project that fires off tons of HTTP requests… and I started wondering:
**Which HTTP client should I actually be using?**
So I went looking for up-to-date benchmarks comparing `requests`, `httpx`, `aiohttp`, `urllib3`, and `pycurl`.
And... I found almost nothing. A few GitHub issues, some outdated blog posts, but nothing that benchmarks them all in one place — especially not including TLS handshake timings.
**What My Project Does**
This project benchmarks Python's most popular HTTP libraries — `requests`, `httpx`, `aiohttp`, `urllib3`, and `pycurl` — across key performance metrics like:
* Requests per second
* Total request duration
* Average connection time
* TLS handshake latency (where supported)
It runs each library multiple times with randomized order to minimize bias, logs results to CSV, and provides visualizations with `pandas` \+ `seaborn`.
GitHub repo: 👉 [https://github.com/perodriguezl/python-http-libraries-benchmark](https://github.com/perodriguezl/python-http-libraries-benchmark)
**Target Audience**
This is for developers, backend engineers, researchers or infrastructure teams who:
* Work with high-volume HTTP traffic (APIs, microservices, scrapers)
* Want to understand how different clients behave in real scenarios
* Are curious about TLS overhead or latency under concurrency
It’s production-oriented in that the benchmark simulates realistic usage (not just toy code), and could help you choose the best HTTP client for performance-critical systems.
**Comparison to Existing Alternatives**
I looked around but couldn’t find an open source benchmark

Should I port my BE to Django?
Hi all,
I've been thinking about this for a while, but I'm stills unsure if I can justify the effort it will take.
I have a backend application written in python. I use SQLalchemy, flask rest and a few classes (pure python) that I made for the specifics of my project.
I spent a reasonable amount of time creating a generic DB class that implements similar things as Django (getone, getcreate, ....) and it works nicely. It also manages DB connections to master-replica cluster.
I miss a lot of the functionality of an admin panel..My understanding is that Django offers those built in, which is a great advantage...
The frontend (svelte) consumes API endpoints to Interact with the backend, so I won't be using views or they'll be just JSON responses.
The backend has two main funcionalities. In one hand, a bunch of scripts that work independently feeding info to the DB and the API that produces the info to the frontend.
All that is currently done in flask, which offers too much freedom to organise the code and I think it'll be a problem going forward. I understand Django is more rigid in that aspect.
So, is it worth port it to Django? What would you consider

Implemented 18 RL Algorithms in a Simpler Way
# What My Project Does
I was learning RL from a long time so I decided to create a comprehensive learning project in a Jupyter Notebook to implement RL Algorithms such as PPO, SAC, A3C and more.
# Target audience
This project is designed for students and researchers who want to gain a clear understanding of RL algorithms in a simplified manner.
# Comparison
My repo has (Theory + Code). When I started learning RL, I found it very difficult to understand what was happening backstage. So this repo does exactly that showing how each algorithm works behind the scenes. This way, we can actually see what is happening. In some repos, I did use the OpenAI Gym library, but most of them have a custom-created grid environment.
