dictf - An extended Python dict implementation that supports multiple key selection with a pretty syntax.

Hi, everyone! I'm not sure if this is useful to anyone because it's a problem you can easily solve with a dict comprehension, but I love a pretty syntax, so I made this: https://github.com/Eric-Mendes/dictf

It can be especially useful for filtering huge dicts before turning into a DataFrame, with the same pandas syntax.

Already on pypi: https://pypi.org/project/dictf/

It enables you to use dicts as shown below:

My experience upgrading project from Flask v1 to v2

I've had one pretty big project which still was running Flask v.1. Finally decided it's time for v.2 which is now a couple years since initial release. A lot of dependencies were upgraded. There was a fair bit of syntax that I had to change, most of the changes were related to SQLAlchemy, WTForms, Jinja filters. Some parameters were renamed. Some parameters that were positional are now named. Some standard form validations stopped working. I could not test everything because the app is fairly big, so some errors occurred in production and were promptly fixed. But every day I discover some new issues. Flask console, which was running fine before upgrade, does not work, I still can't fix it. Flask-Migrate is also broken, I can't run any migrations.

More specifically, trying to load Flask console throws these 2 errors:

flask.cli.NoAppException: While importing 'wsgi', an ImportError was raised

ModuleNotFoundError: No module named 'wsgi'

And Flask-Migrate complains about db connection:

sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1045, "Access denied for user 'user'@'host' (using password: YES)")

The connection is configured using SQLALCHEMY_DATABASE_URI in config, and works fine when the Flask server is running, but for some reason

Do any of you code to de-stress?

I work as a mechanical engr/program manager in the biomedical field, but love to hobby code on the side. I enjoy scraping datasets, from real estate to car auction websites, and running different analyses on it. Simple up front metrics, sorting, and deeper ML stuff with scikit.

I've recently cut down on drinking almost entirely and have found myself gravitating towards my laptop at the end of the day to just toy around with code.

There is something oddly comforting about seeing all the multi colored code in VScode. Something pleasantly pleasing about expanding your knowledge to learn better and simpler ways to code things. And something rewarding about getting results that you'll probably never use again after dedicating hours and sometimes weeks of work.

I hope this feeling doesn't fade.. I used to love photography in HS, but started making money doing it and lost most of my passion for it.

Help - no such file or directory but was fully functioning earlier

Hey all,

I was using JupyterLite and the notebook was doing everything I needed it to until I started getting "error no such file or directory" later in the day. I hadn't changed anything to the csv file's location and even played around with different names, paths, copy path, ect.

I have used Jupyter Notebooks online in the past and haven't seen anything like this. Currently in the process of downloading it for Windows and am going to see how that goes.

Thanks in advance!

You wrote some code but it was waste

Have it ever happened to you that you have a good idea for a project, you start building the project giving it most of your time and after days you come to know that there was an way way to do it

I always wanted to create a website that will do something unique, I just wanted to show off my website in college.
So i got an idea of creating a flask python website, and after completing it i was just going to host it on pythonanywhere and then i realised that the whole website can be made without using flask with just html

I worked with modules like pillow, os, shutil only to know that there was a really easy way to do all that, at this point i'm like shocked because i experienced something like this for the first time....

Best practice for postgres partitioning

Hey all!


I am looking for the best libary to work with postgres (13.X +) partitioning,
I have used until now 'django-pg-partitioning' but it is no longer maintned and not supported in newer djagno versions.


I am familiar with 'django-postgres-extra' but I have a problem with this package since it generates automatically the 'default' partition and can only be removed manually from the migrations (or am I missing something?)


Thank you all.

Automatically Open Notebooks

Hey everyone, I'm fairly new to Jupyter Notebooks, but I love them! I've been using one to keep track of things I find tricky while I'm learning F#. Does anyone know of an extension or setting that would allow me to have quick access to my notebooks without having to go and open it every time I open a new folder? I'm doing some training through the Exercism website and doing the challenges locally. Let me know if you have any ideas!

Thanks!

How long did it take you to code by second nature?

I once read that programmers will get to a place where they’ll be able to open an IDE and start working on a project at the same speed in which it takes a person to open excel and start building a table, how long did it take you to get there?

I am at that point using SQL, where I can open an IDE and starting building what I need without thinking too much but it’s hard to imagine I’ll ever get there with Python. I know there’s different packages, modules, and etc. but excluding the complex things, how long did it take you to get to a point where you could open an IDE and starting putting code together like it’s second nature?

Python + containerd? Who might be interested?

There is currently only one poorly maintained (if at all) Python binding for the containerd API:

https://pypi.org/project/contain...
I'd rather not build on it.

I would like to have a similar convenient wrapper for containerd just like the Docker Engine API: https://pypi.org/project/docker/


Who else would be interested in such a package?

[P] Godot+RWKV standalone prebuilt binary (ubuntu/nvidia)

# RWKV+Godot

## What

### Godot

The Godot Engine is a free, all-in-one, cross-platform game engine that makes it easy for you to create 2D and 3D games.

### RWKV

RWKV is an RNN with Transformer-level LLM performance, which can also be directly trained like a GPT transformer (parallelizable). And it's 100% attention-free. You only need the hidden state at position t to compute the state at position t+1.

### RWKV-CPP-CUDA

RWKV-CPP-CUDA is a c++/cuda library I created that implements the RWKV inference code in pure cuda. This allows for compiled code with no torch or python dependencies, while allowing the full use of GPU acceleration.
The code implements 8bit inference, allowing for quick and light inference.

### Godot+RWKV

Godot+RWKV is a Godot module that I developed using RWKV-CPP-CUDA, and allows the development of games and programs using RWKV to be developed and distributed using godot, without the need to install complex environments and libraries, for both developers and consumers.

## Why

* I felt I could achieve it
* Its something thats needed to advance the use of AI in consumer devices
* The lols
* Attention, because I didnt get much growing up, and RWKV has none
* ADHD hyperfocus
