Reactive Notebook for Python - An Alternative to Jupyter Notebook

What the Project Does :

Marimo is an open-source reactive notebook for Python: reproducible, git-friendly, executable, shareable as apps.

Run a cell or interact with a UI element, and Marimo automatically runs dependent cells (or marks them as stale), keeping code and outputs consistent. Marimo notebooks are stored as pure Python, executable as scripts, and deployable as apps.

Target Audience :

The project is primarily aimed at data scientists, researchers, and educators. They can make featureful, interactive, and beautiful notebooks that let users filter, slice, and drill-down to their heart's content. Marimo can also enable them to build maintainable internal tools using just Python, without the hassle of custom frontends, infra, endpoints, and deployments.

Comparison :

vs JupyterLite - a WASM powered Jupyter running in the browser. However, it is not reactive like Marimo.

vs IPyflow - a reactive notebook for Python implemented as a Jupyter kernel. However, it is not WASM compatible.

vs Jupyter - marimo is a reinvention of the Python notebook as a reproducible, interactive, and shareable Python program that can be executed as scripts or deployed as interactive web apps - without the need of extensions or additional infrastructure

sql-compare: package to compare SQL schemas

## What My Project Does

This package allows to compare two SQL files (or strings) to know whether their statements are the same or not. The comparison doesn't care about the order of the columns in a table or the order of the values in an enumerator. It also excludes irrelevant data like comments.

GitHub repository

PyPI

Its main usage is to compare the schemas of two databases (e.g. staging and production).

At Mergify, we use it in our test suite to check that the migration scripts generated by Alembic will create the database schema expected by the SQLAlchemy models. I wrote a blog post about the creation of the package.

## Target Audience

We use it in our CI/CD. This package is meant for testing mainly, but it could be used for something else probably.

This package is ready for production.

We have been using it at Mergify for several months now. Our test suite fails whenever Alembic misses something in a migration script. We deliver to production several times a day thanks to that.

## Comparison

We didn't find any suitable alternative.

Alembic can compare a database schema with SQLAlchemy models, but it doesn't detect every differences.

We used migra in the past, but it is not maintained anymore.

Help with database commits from a form.

Hello! I'm pretty new to Flask and struggling with transferring data from a form to an SQL Database. The form is within a modal, which works perfectly and will redirect back to the main page once the form is submitted. However, the data from the form is not transferred to the SQL Database that I have associated with this project. I'm sure I'm missing something quite simple, help would be appreciated! If any more code screenshots are needed please let me know.

Reduce number of models

I currently have:

- ORM model, courtest of SQLAlchemy
- Form model, courtesy of WTForms
- Model logic in routes... Which mostly calls ORM class methods.

How can I consolidate all of that? Any best practices I need to be aware of?

I'm a flask addict, convince me to switch to Django

I've been developing web apps with Flask for a while now and love its simplicity and flexibility. It's lightweight and allows me to pick and choose the components I need. However, I've heard a lot about Django's "batteries-included" philosophy and its robust feature set.

Everyone around me says that Django is way better, I really tried to switch but it's really hard.

Convince me why I should give Django a shot!

Emotion classification & Analysis

Hello everyone,

New to the web building community - need some advice

Hey Django community!

I'm new to the web building community but not entirely alien to programming. Though, having said that, my experience lies in SQL and SAS.

Can someone advice on the benefits of Django as compared to Flask if I want to build a website for price comparison?

I have an idea where users can compare prices and make the best decision for their purchase.

Read up on the benefits of flask and Django but I am not from a computer science background so I can be quite illiterate to the technical jargons.

Would appreciate if anyone could dumb it down for me and advice me on flask or Django for a "Price Comparison" website!

Thank u!

I'm a Python Backend Developer, How to Create a Modern and Fast Frontend?

Hi everyone,

I'm a backend developer working with Python and I'm looking for a simple and quick way to create a modern and clean frontend (web app) for my Python APIs.

I've been learning Next.js, but I find it a bit difficult and perhaps overkill for what I need.

Are there any tools or platforms for creating simple and modern web apps?
Has anyone else been in the same situation? How did you resolve it?
Do you know of any resources or websites for designing Next.js components without having to build them from scratch?

Thanks in advance for your opinions and recommendations!

Scope Boundaries for Notebooks — Research Study on an extension I've been developing

Hi Everyone. My name is Eric Rawn. I’m a PhD student at UC Berkeley working with my advisor Professor Sarah Chasins. I research how to make notebook programming environments better, and have been working on an extension for notebooks which introduces scope boundaries to collections of cells. We think this might help programmers avoid some of the pain points with notebooks, but we won’t know until we study its use in the real world. The goal is to make it easier to keep variables tidy within a notebook without requiring programmers to change how they like to use notebooks. We’re interested in evaluating how our extension aids how real users program (you all!), and so we’re running a 4-6 week study with folks who use Jupyter notebooks regularly in their everyday programming.

The extension will log some usage data locally on your machine, which you'll send to me at the end of the study. We'll then spend about an hour chatting about your experience, the kind of work you do daily, how you use notebooks, and any other thoughts or feedback you have. Participants will be compensated for their time spent interviewing, at $30/hour. The consent form has detailed information about the

Shed Skin restricted-Python-to-C++-compiler 0.9.9

I have just released version 0.9.9 of Shed Skin, a restricted-Python-to-C++ compiler. It comes with a whole host of small improvements, and also a nice new (constructive solid geometry) example, which becomes about 15 times faster on my system (not 15%.. 15 times!).

If you think this is a cool project, please consider helping out. There is always enough work (low-hanging fruit even) on both the Python and C++ side.

zealot: prevent N+1 queries in Django

hey everyone!

i just released zealot, a library for detecting N+1 queries in your Django project.

i've wanted something like this for a long time. there are some similar libraries out there, but none of them did everything i wanted, and the most popular would miss certain types of N+1.

zealot is pretty simply: install it, and it'll raise an exception (or log a warning) whenever it detects an N+1 query, with a helpful error message so you can fix it and be on your way.

all feedback is very welcome!

I made a Python library to plot chemical trends | Plotium

# What does my Project do?

Plotium is a python library used to plot chemical trends like Atomic radii, Electronegativity, etc of specific parts of the periodic table, like types of elements, group or a specific block.

Right now, Plotium can plot trends of:

1. Electronegativity

2. Density

3. Atomic Radii

4. Melting Point

5. Boiling Point



Divided into:

1. Block Wise (S,P,D,F)

2. Types (Actinoids, Lanthanoids, etc)

3. Groups (1 - 18)

# Target Audience

Students/people who love chemistry. This library will also be useful for teaching students several exceptions and trends.

# Comparison

I haven't seen any trend plotter other than one hotmap plotter. But what I'm aiming is graphing these trends.
