I have A question about my code in python

The code should make 100km

then subtract from it 100 meter

then 100cm then

then 100 mm

then Evaluate Exactly the value

THat is The file Which I wrote the correct Code

import Methods as M
def Convert_To_Decimal(Value):
    for i in range(len(Distance_List)-1):
        # Convert To Decimal
        V = Convert_Distance(Distance_List[i], Distance_List[i+1], Value)
       
        if V!=0:
            print(V, Distance_List[i+1], end=" ")  
        V=V-int(V)
    print()
        # Print Number
       
def Convert_Distance(From, To="1km", Value=0):
   
    return round(Value * M.Return_distance(From) / M.Return_distance(To),10)

def Minus():
    B = 100
    for Label in Distance_List[1:]:
        print("Subtracting 100", Label)

How to effectively understand the Django repository (or any large codebase)?

The reason I am asking this question stems from my exploration of the Django codebase, which began after I finished studying Django for Beginners 4.2 by Will Vincent. Throughout the book, I often found myself asking questions like, how do CBVs and GCBVs work? Why do they inherit from the View class? Why is .as_view() used with CBVs and GCBVs, but not with FBVs?

These questions stayed in my mind, so I decided to explore the Django repository to understand them better. While most of the code (if not all) went over my head, I believe I now partially "understand" the "why" behind some of these concepts.

From my exploration, I realized that as_view() essentially “converts” CBVs and GCBVs into functions because the foundational way of building Django views are FBVs. CBVs and GCBVs are built on top of FBVs. CBVs aim to achieve better separation of logic by mapping HTTP methods to specific class methods, while GCBVs are built on top of CBVs to simplify common tasks like creating, updating, deleting, querying and displaying data e.c.t.

I am not entirely sure if my understanding is accurate, but this is how I have interpreted it so far.

My question is, How can I understand

Where to start with headless allauth

Hey everyone!

I've been taking my first steps into front end development, I've chosen sveltekit and am loving it so far. Now for the tricky part, authentication. There is a boilerplate project for allauth in react but I find the documentation to be lacking any guidance on implementation, any pointers?

After changing flask port, port 5000 is not working anymore

Hey, I was sending API request to my flask application at 192.168.X.X:5000 from my local network for last few days.
Today I asked my friend to try and send API request , because I was in a hurry, I didn't have time to open new ports and I remembered I had port 25565 already opened so I used that one (so it was pub-ip:25565).

Now that I have time, I opened port 5000 and now the script is not working when I go back to port 5000.
I tried again with 25565 and its working, I tried from port 12345 and its working. Just the 5000 is NOT working.
Any suggestions?

When I start the app:

Affordable and Reliable Hosting for Django Project with PostgreSQL, Redis, and AWS S3?

I'm developing a Django project which includes several key modules:

AI Integration: Uses OpenAI to provide crop recommendations and chatbot features.
Weather Module: Incorporates weather data to assist with planning and insights.
Mapping Tools: Utilizes Mapbox for GIS-related functionalities, like visualizing field and crop data.
User Management: Manages user accounts, authentication and auth.

The app requires PostgreSQL for the database, Redis for caching, and AWS S3 for media and static files. I’m looking for a hosting platform that is both affordable and highly reliable for these requirements. Any recommendations?

D Everyone is so into LLMs but can the transformer architecture be used to improve more ‘traditional’ fields of machine learning


i’m thinking things like recommendation algorithms, ones that rely on unsupervised learning or many other unsupervised algos

i’ll look more into it but wanted to maybe get some thoughts on it

A lightweight Python wrapper for the Strava API that makes authentication painless


**What My Project Does**

Light Strava Client is a minimalist Python wrapper around the Strava API that automates the entire OAuth flow and token management. It provides a clean, typed interface for accessing Strava data while handling all the authentication complexity behind the scenes.
Key features:

* Automated OAuth flow (just paste the callback URL and you're done)
* Automatic token refresh handling
* Type-safe responses using Pydantic
* Simple to extend with new endpoints
* No complex dependencies

**Target Audience**

This is primarily designed for developers who want to quickly prototype or build personal projects with Strava data. While it can be used in production, it's intentionally kept minimal to prioritize hackability and ease of understanding over comprehensive feature coverage.

**Comparison**

The main alternative is stravalib, which is a mature and feature-complete library. Light Strava Client takes a different approach by offering a minimal, modern (Pydantic, type hints) codebase that prioritizes quick setup and hackability over comprehensive features.

The code is available here: [https://github.com/GiovanniGiacometti/Light-Strava-Client](https://github.com/GiovanniGiacometti/Light-Strava-Client)

I'd love to hear your thoughts or feature suggestions!

A pytest plugin to run async tests 'concurrently'

**What My Project Does**

System/Integration tests sometimes can take really long time, due to spending huge amount of time waiting for external services responding. Pytest-asyncio make async tests testable, but run them sequentially. Pytest-xdist spinup multiple processes, blew up our fragile server during tests collection :(

* This plugin is to solve this by running asynchronous tests in true parallel, enabling faster execution for high I/O or network-bound test suites.
* Also give you high flexibility to specify tests that can run in parallel.
* Compatibility with Pytest-asyncio if you are already deep in rabbit hole.

**Target Audience**

The plugin is mainly targeted system/Integration tests, which is heavily bounded by I/O, network or other external dependency.

This plugin would more or less Break Test Isolation Principle. So make sure your tests is ok to run concurrently before you use this plugin.

**Comparison**

As mentioned above, unlike `pytest-asyncio`, which runs async tests sequentially, `pytest-asyncio-concurrent` takes advantage of Python's asyncio capabilities to execute tests concurrently by specifying async group.

**Try this out!**

Welcome to try this out, and let me know your feedback!

YTMASC, take your YouTube music library to anywhere!

GitHub

I've been developing this tool for quite a while now, but was hesitant to share it because I had many things in mind to implement. However I'd like to share the project as about half of the stuff is in there and functional.

# What My Project Does

YTMASC gets your library by:

Scraping your YouTube library page (yes I know this is a horrible way of doing it but it's the easiest, I've something else in mind don't worry but it'll be the least of my priorities :D)
Imports RiMusic databases (also ViMusic since the fork didn't change the database schema)
A CSV file of your own that has 3 columns (\watch_id, artist, title)

And puts data from these sources into a simple json file. The information here is later used at the tasks you want to run.

Also, there are some tools to help you fix any issues you may run into (YouTube making the video unavailable, migration of old libraries etc.)

It's mainly available as CLI with a config file you can tinker with, I had written a tkinter GUI before but I don't want to maintain it anymore due to it being well, unmaintainable because I didn't think I'd be developing

🌀 Interstice: The Zero-Player Game Simulator

PyPI | Website | GitHub

Hey r/Python!

I’m excited to introduce Interstice, a zero-player game simulator that explores emergent behavior on a 2D grid. This Python package brings to life complex systems where entities evolve according to simple rules perfect for those curious about simulation, artificial intelligence, and game theory.

# What My Project Does

Interstice is a zero-player game, meaning there’s no user input once the game begins. The simulation evolves autonomously based on pre-defined rules:

Entities: Different "agents" (like Demons and Soldiers) interact on a grid.
Interactions: These agents follow unique behaviors that create emergent patterns.
Visualization: See the grid evolve in real-time through a webpage.

This game lets you experiment with different rules, initial states, and grids to discover the fascinating results of these interactions.

# Target Audience

A fan of games like Conway's Game of Life or Langton's Ant,
Curious about emergent behavior in autonomous systems,
Interested in creating interactive simulations for fun or research

# Comparison

Interactive: Modify rules and observe changes on the fly.
Python-first: Built with Python developers in mind, making it easy to extend.
Creative: Design unique simulations that explore autonomous systems.

# Check it Out

PyPI Package: Install with pip install interstice
