Are there any boilerplates or templates you are using currently? If so, what is your project?

Want to learn to review code and get a sense for proper structure and gain in depth knowledge about overall development. What modules are a must for your development? I also enjoy reading about another developer’s workflow and productivity.

Using Django+Sqlite in production

I've been researching the use of Sqlite in production and came across this thread which has some resources, mainly about the benefits and also how to performance tune Sqlite.

My intent right now is to keep my app on Sqlite. The application is a B2B app with limited number of users, and it is not write heavy (a few hundred writes per day). It also simplifies my tech stack.

I'd like to check if someone has resources specific on how to deploy and run a Django+Sqlite app.

Over in the Ruby on Rails world, I saw a movement to help developers achieve this, and was wondering if there is something equivalent in the Django.

Cogitator - A Python Toolkit for Chain-of-Thought Prompting

GitHub Link: [https://github.com/habedi/cogitator](https://github.com/habedi/cogitator)

**What my project does**

Cogitator is a Python library/toolkit that makes it easier to experiment with and use various chain-of-thought (CoT) prompting methods for large language models (LLMs). CoT prompting is a family of techniques that helps LLMs improve their reasoning and performance on complex tasks (like question-answering, math, and problem-solving) by guiding them to generate intermediate steps before giving a final answer.

Cogitator currently provides:

* Support for OpenAI and Ollama as LLM backends.
* Implementations for popular CoT strategies such as Self-Consistency, Tree of Thoughts (ToT), Graph of Thoughts (GoT), Automatic CoT (Auto-CoT), Least-to-Most Prompting, and Clustered Distance-Weighted CoT.
* A unified sync/async API for interacting with these strategies.
* Support for structured model outputs using Pydantic.
* A basic benchmarking framework.

The project is in beta stage. The README in the GitHub repository has more details, installation instructions, and examples.

**Target audience**

* AI/ML researchers looking to experiment with or benchmark different CoT techniques.
* Python developers who want to integrate more advanced reasoning capabilities into their LLM-powered applications.

In general, CoT could be useful if you're working on tasks that need multi-step reasoning or want to improve the reliability of LLM outputs for more complicated queries.

**Why I made this**

I started developing Cogitator because I found that

Looking for help regarding a flask project (I want to input question (with both text and equations) , save it in MySQL and print in both word doc and pdf)

I am working on a basic question paper generator where users can enter questions for each subject, and the the questions are saved in MySQL. The admin can generate question papers in form of both pdf and word. I am unable to find a way to let users to add questions that has equations or formulas. I tried using tinymce and mathjack but it doesn't seem to support all formats (like the bigger fractions). I also tried rendering latex to text or image and is too complicated for me to understand how to make it work properly. I do not want to paste the equation/formula as an image in the word file, I need to to be in proper human readable format. I want the outputs both in word and pdf formats. Please help.

I built my own asyncio to understand how async I/O works under the hood

Hey everyone!

I've always been a bit frustrated by my lack of understanding of how blocking I/O actions are actually processed under the hood when using async in Python.

So I decided to try to build my own version of asyncio to see if I could come up with something that actually works. Trying to solve the problem myself often helps me a lot when I'm trying to grok how something works.

I had a lot of fun doing it and felt it might benefit others, so I ended up writing a blog post.

Anyway, here it is. Hope it can help someone else!

No, not every website needs to be an SPA. Built something with Django—fast, clean, and people love it.

I just launched a small project using plain Django (no SPA, no fancy frontend frameworks).

It’s fast, clean, and people love using it.

I see so many projects defaulting to SPAs, even when it’s not necessary. Django let me move fast, keep things simple, and focus on the core experience—not on wiring up a complex frontend stack.

Honestly, that’s what I love about Django. It gives you everything you need to ship something solid without overengineering.

Also—thank you to this subreddit. I’ve learned a lot here. If anyone’s curious about the stack or wants to ask anything, happy to chat.

My journey after 1 month on internship using django

I have been using Django almost for a month (The first days in the company I did nothing. I was only meeting new people).

They told me to use whatever I want, so I chose Python because I'm interested in machine learning so I saw it as an opportunity for my future. They want to create automation and I didn't know where to deploy it so I decided to deploy everything I do for the company in the web then I decided to use Django.

I have learned a lot since then, sometimes I get stressed but reading code and with AI tools I reach to fix the errors I have on my code but of course I have a ton to improve and I'll do it with the time, I just started my journey in this world and I'm so happy for it because since I was a kid I love technology

Django relevance

I'm new to the dev world and would like some help.

What factors do people consider while learning a language. For example, right now I often come across people pushing Rust and Go. I suppose my question is, is Django still relevant for back end?

Tuples vs Dataclass (and friends) comparison operator, tuples 3x faster

I was heapifying some data and noticed switching dataclasses to raw tuples reduced runtimes by \~3x.

I got in the habit of using dataclasses to give named fields to tuple-like data, but I realized the dataclass wrapper adds considerable overhead vs a built-in tuple for comparison operations. I imagine the cause is tuples are a built in CPython type while dataclasses require more indirection for comparison operators and attribute access via __dict__?

In addition to dataclass , there's namedtuple, typing.NamedTuple, and dataclass(slots=True) for creating types with named fields . I created a microbenchmark of these types with heapq, sharing in case it's interesting: https://www.programiz.com/online-compiler/1FWqV5DyO9W82

Output of a random run:

tuple : 0.3614 seconds
namedtuple : 0.4568 seconds
typing.NamedTuple : 0.5270 seconds
dataclass : 0.9649 seconds
dataclass(slots) : 0.7756 seconds

Flask is driving me crazy

ok so i started learning flask as part of a course im in. At first, it felt like it was easy with some all-in-one code ive made. Like managing the routes, using url_for, creating the connection with the database. Then i tried to make the flask tutorial from their website, now i feel the more dumb than i used to, lol. i think they just throw code on the screen and you gotta copy, i mean, i can totally understand what the code does by reading it, but i cant imagine me learning anything from it. I dont know if i am going to be able to get all of this stuff in my head.


Is there any other place i can learn flask or Python webdev thats does it slowly and/or in a better way?

How Big Softwares are planned and executed.

Hi,

This is a long post. Thanks for Reading.

Honestly, I need some senior with whom I can talk.


Backend: Django , Frontend: React + Typescript , Database: postgres , Cloud: AWS


So, basically I work in a company which has been in business for more then 20 years, It's a medium sized organization. But they never integrated tech into their system. They are not going to sell any software, they just want everything for themselves.


I have been hired as a Team lead here, I hired the others guys as well. So, right now we have core frontend and backend devs . We work very closely. They have hired us so that we can automate their internal processes.


None of us is much experienced, Actually honestly I am just a fresher. And others here are just 1yr-2yr experienced.


Others just code, they aren't really that interested into designing and planning.


Now, I am facing a lot of issues, I am desperate to know how these things are handled in Big Enterprises , Large tech companies. None of our project is small, All of the projects are quite complex
