Are there any DX standards for building API in a Python library that works with dataframes?

I'm currently working on a Python library (kawa) that handles and manipulates dataframes. My goal is to design the library so that the "backend" of the library can be swapped if needed with other implementations, while the code (method calls etc) of the library do not need changing. This could make it easier for consumers to switch to other libraries later if they don't want to keep using mine.

I'm looking for some existing standard or conventions used in other similar libraries that I can use as inspiration.

For example, here's how I create and load a datasource:

import pandas as pd
import kawa
...

citiesandcountries = pd.DataFrame(
{'id': 'a', 'country': 'FR', 'city': 'Paris', 'measure': 1},
{'id': 'b', 'country': 'FR', 'city': 'Lyon', 'measure': 2},
)

uniqueid = 'resource{}'.format(uuid.uuid4())
loader = kawa.newdataloader(df=self.citiesandcountries, datasourcename=uniqueid)
loader.createdatasource(primarykeys='id')
loader.loaddata(resetbeforeinsert=True, createsheet=True)

and here's how I manipulate (run compute) the created datasource (dataframe):

import pandas as pd
import kawa

What is the best approach to avoid repetition of a try-except structure when fetching models?

I’m fetching data across multiple models and have the following try-exception structure repeated a lot:

try:
model .get / .filter
except Model.DoesNotExist:
handle…
except Model.MultipleInstancesReturned:
handle…

Is it bad to just have this structure repeated across every model I’m querying or is there a cleaner way to generalize this without so much repetition?

Arakawa: Build data reports in 100% Python (a fork of Datapane)


I forked Datapane (https://github.com/datapane/datapane) because it's not maintained but I think it's very useful for data analysis and published a new version under a new name.

https://github.com/ninoseki/arakawa

The functionalities are same as Datapane but it can work along with newer DS/ML libraries such as Pandas v2, NumPy v2, etc.

## What My Project Does

Arakawa makes it simple to build interactive reports in seconds using Python.

Import Arakawa's Python library into your noscript or notebook and build reports programmatically by wrapping components such as:

- Pandas DataFrames
- Plots from Python visualization libraries such as Bokeh, Altair, Plotly, and Folium
- Markdown and text
- Files, such as images, PDFs, JSON data, etc.

Arakawa reports are interactive and can also contain pages, tabs, drop downs, and more. Once created, reports can be exported as HTML, shared as standalone files, or embedded into your own application, where your viewers can interact with your data and visualizations.

## Target Audience

DS/ML people or who needs to create a visual rich report.

## Comparison

Possibly Streamlit and Plotly Dash. But a key difference is whether it's dynamic or static.
Arakawa creates a static HTML report and it's suitable for periodical reporting.

Helios: a light-weight system for training AI networks using PyTorch

# What My Project Does

Helios is a light-weight package for training ML networks built on top of PyTorch. I initially developed this as a way to abstract the boiler-plate code that I kept copying around whenever I started a new project, but it's evolved to do much more than that. The main features are:

* It natively supports training by number of epochs, number of iterations, or until some condition is met.
* Ensures (as far as possible) to maintain reproducibility whenever training runs are stopped and restarted.
* An extensive registry system that enables writing generic training code for testing multiple networks with the same codebase. It also includes a way to automatically register all classes into the coressponding registries without having to manually import them.
* Native support for both single and multi-GPU training. Helios will automatically detect and use all GPUs available, or only those specified by the user. In addition, Helios supports training through torchrun.
* Automatic support for gradient accumulation when training by iteration count.

# Target Audience

* Developers who want a simpler alternative to the big training packages but still want to abstract portions of the training code.
* Developers who need to test multiple

How to find remote world wide jobs?

I'm currently working at a small company in my hometown. Python and especially django are not common here. Where I'm working modern technologies like microservices architecture, Test-Driven Development (TDD), or cutting-edge tools aren't used. I'm eager to work on high-load projects. Additionally, I'm looking for opportunities with a higher salary. Are there any other platforms besides Upwork where I can find worldwide remote jobs or roles that offer relocation?

Just Released Version 0.5.0 of Django Action Triggers!

First off, a huge thank you to everyone who provided feedback after the release of version 0.1.0! I've taken your input to heart and have been hard at work iterating and improving this tool. I’m excited to announce the release of version 0.5.0 of django-action-triggers.

There’s still more to come in terms of features and addressing suggestions, but here’s an overview of the current progress.

# What is Django Action Triggers

Django Action Triggers is a Django library that lets you trigger specific actions based on database events, detected via Django Signals. With this library, you can configure actions that run asynchronously when certain triggers (e.g., a model save) are detected.

For example, you could set up a trigger that hits a webhook and sends a message to AWS SQS whenever a new sale record is saved.

# Supported Integrations?

Here’s an overview of what integrations are currently supported:

Webhooks
RabbitMQ
Kafka
Redis
AWS SQS (Simple Queue Service)
AWS SNS (Simple Notification Service)
AWS Lambda (New in version 0.5.0)
GCP Pub/Sub (New in version 0.5.0)

# Comparison

The closest alternative I've come across is Debezium. Debezium allows streaming changes from databases. This project is different and is more suited for people who want a Django integration in the form of a library. Debezium on

Python 3.13's best new features

Everyone has their own take on this topic and here is mine as both a video and an article.

I'm coming with the perspective of someone who works with newer Python programmers very often.

My favorite feature by far is the new Python REPL. In particular:

- Block-level editing, which is a huge relief for folks who live code or make heavy use of the REPL
- Smart pasting: pasting blocks of code just works now
- Smart copying: thanks to history mode (with F2) copying code typed in the REPL is much easier
- Little niceities: exit exits, Ctrl-L clears the screen even on Windows, hitting tab inserts 4 spaces

The other 2 big improvements that many Python users will notice:

- Virtual environments are now git-ignored by default (they have their own self-ignoring .gitignore file, which is brilliant)
- PDB got 2 fixes that make it much less frustrating: breakpoints start at the breakpoint and not after and running Python expressions works even when they start with help, list, next, or another PDB command

These are just my takes on the widely impactful new features, after a couple months of playing with 3.13. I'd love to hear your take on what the best new features are.

I love Django! I don't use any third party django extensions, am I missing out?

Hello everyone,
Django has been really good lately for the different applications I use. Beyond the code, even the philosophy of Django has helped me structured my thinking. I also started using Cookie Cutter, that stuff is awesome. I have been tempted to use certain django extensions such as Django Markdown (for supporting markdown) and Django Ledger (for accounting stuff I knew now much about).

In the end, I didn't implement neither because I found alternative solutions. I would really love hearing from the community?
1. Do you stand by any specific django extensions that you use in your projects?
2. How is your experience like as a someone who contributes to extensions?
3. What were some of your negative experiences with extensions?

Niquests v3.9.0 Released

We are proud to announce our latest advancement for Niquests. Since last time we published in
this community, a lot of things happened.

We landed for you:

- Post-Quantum Security for QUIC
- QUIC v2
- Integrated WebSocket Support
- HTTP Trailers
- Early Responses like "103 Early Hints"
- Happy EyeBalls

The project reached 800+ stars with half a million downloads since the beginning.
We are grateful to Microsoft and involved parties for funding our work through the Microsoft FOSS Fund program.

What My Project Does

Niquests is a HTTP Client. It aims to continue and expand the well established Requests library.
For many years now, Requests has been frozen. Being left in a vegetative state and not evolving,
this blocked millions of developers from using more advanced features.

Target Audience

It is a production ready solution. So everyone is potentially concerned.

Comparison

Niquests is the only HTTP client capable of serving HTTP/1.1, HTTP/2, and HTTP/3 automatically.
The project went deep into the protocols (early responses, trailer headers, etc...) and all related
networking essentials (like DNS-over-HTTPS, advanced performance metering, etc..)

# GitHub:

[https://github.com/hlop3z/zmag/](https://github.com/hlop3z/zmag/)

# What My Project Does:

ZMAG is a framework designed for building **network APIs** rather than traditional web applications, leveraging the unique combination of **GraphQL** and **ZeroMQ**. With **ZeroMQ** you can create different system. Examples:

* **Request / Response**
* **Push / Pull**
* **Publish / Subscribe**

# Target Audience:

Currently is a toy project, I’m going to use it to manage projects internally, which I made with Django and FastAPI.

# Comparison:

As far as I know there’s nothing that combines **GraphQL** and **ZeroMQ** into a framework. Something similar I know that exist but not with GraphQL is [https://www.zerorpc.io/](https://www.zerorpc.io/)
