I Created the Definitive AUTOMATIC Shiny Hunter for Pokémon BDSP in Python

What My Project Does: Hey everyone! I am Dinones! I coded a Python program using object detection that lets my computer hunt for shiny Pokémon on my physical Nintendo Switch while I sleep. So far, I’ve automatically caught shiny Pokémon like Giratina, Dialga or Azelf, Rotom, Drifloon, all three starters, and more in Pokémon BDSP. Curious to see how it works? Check it out! The program is available for everyone! Obviously, for free; I'm just a student who likes to program this stuff in his free time :)

The games run on a Nintendo Switch (not emulated, a real one). The program gets the output images using a capture card, then, it process them to detect whether the pokemon is shiny or not (OpenCV). Finally, it emulates the joycons using bluetooth (NXBT) and control the Nintendo.

I also want to know what do you think about it: Is it fair to use it in singleplayer? And multiplayer?

Target Audience: All Pokémon BDSP gamers.
Comparison: As far as I know, nobody did this before.

I built a Python Front End Framework

This is the first real python front end framework you can use in the browser, it is nammed PrunePy :

# What My Project Does

The goal of this project is to create dynamic UI without learning a new language or tool, with only basic python you will be able to create really well structured UI.

It uses Pyscript and Micropython under the hood, so the size of the final wasm file is bellow 400kos which is really light for webassembly !

PrunePy brings a global store to manage your data in a crentralised way, no more problems to passing data to a child component or stuff like this, everything is accessible from everywhere.

# Target Audience

This project is built for JS devs who want a better language and architecture to build the front, or for Python devs who whant to build a front end in Python.

# Comparison

The benefit from this philosophy is that you can now write your logic in a simple python file, test it, and then write your html to link it to your data.

With React, Solid etc it's very difficult to isolate your logic from your html so it's very complex to test it, plus you are forced to test your

trying to set up a virtual environment on a linux and windows machine multiple times but failed.

i have a flask project (can't share the github repo because it is private) and I've tried setting it up on my fedora linux machine. the os by default had python 3.12 and I can't remove it because some core packages depend on it. I'm trying to set up a project with pipenv and after I run pipenv install, I get multiple resolution failures and in the error logs, I see that it is picking up some resolverdotpy files from my python3.12 directory.
i have tried specifying the python version as pipenv --python 3.8 install, but no luck. what can I do?

Question about transforming code into a web application

Good morning. I had written a large Python code (>500 lines) for a project, and was trying to make a self serve web application for this in Flask. I got the "hello world" and stuff down in flask, but now I am having trouble understanding how to move forward...do I simply copy paste my code into the main() function in app.py? Because I tried a test code like that (Just one input and an output) and the website didn't display anything.

Tl;dr: Trying to make a massive python code into a Flask web app, did the "hello world" code, not sure how to proceed.

If you could go back and give your beginner Django self one piece of advice, what would it be?

For the seasoned Django developers out there - as you look back on your own journey, what's one insight or lesson you wish you had known when you were just starting out?

I'm a junior Flutter developer who is excited to dive into backend development with Django. As someone new to the field, I'm keen to learn from the experienced Django developers in this community.

Looking back, is there anything in particular you would have approached differently in learning and using the Django framework? What's one piece of advice you wish you could give your beginner self?

I'm especially interested in any insights on:

- Key concepts or techniques that were game-changers in your Django journey

- Resources (books, tutorials, projects) you found invaluable as a beginner

- Common beginner pitfalls to avoid or best practices to adopt early on

- Aspects of Django that were challenging to grasp at first but clicked later on

Has there ever been a proposal for a zero-argument form of `slice()`?

I'm studying Pandas multi-indexing, which uses `slice(None)` [in some spots](https://pandas.pydata.org/docs/user_guide/advanced.html#using-slicers) and it seems ugly so I started wondering the title.

e.g.

dfmi.loc["A1", (slice(None), "foo")]

vs

dfmi.loc["A1", (slice(), "foo")]

Obviously, five extra keystrokes is not a big deal and this is a relatively niche usage, but I don't see any logical reason [`slice`](https://docs.python.org/3/library/functions.html#slice) shouldn't have a zero-argument form. I mean, the syntactic form, `:` doesn't have any value attached to it, so why should the callable form?

As of now, it mostly follows [`range`](https://docs.python.org/3/library/functions.html#func-range)'s signature, requiring either `stop` or `start, stop, step`.

---

**Edit:** NVM, I just realized you can use a convenience object like Pandas [`IndexSlice`](https://pandas.pydata.org/docs/reference/api/pandas.IndexSlice.html), which gives you syntactic sugar for this ***and*** more complicated indexing.

>>> idx = pd.IndexSlice
>>> idx[:]
slice(None, None, None)
>>> idx[:, ...]
(slice(None, None, None), Ellipsis)

Thus:

dfmi.loc["A1", (idx[:], "foo")]
# or
dfmi.loc["A1", idx[:, "foo"]]

All `IndexSlice` does is expose `__getitem__`:

> class _IndexSlice:
> def __getitem__(self, arg):
> return

Do you guys hardcode your backend auth?

So, I'm working on this non-profit project and have just finished the login and registration pages and APIs. I still need to deal with JWT and enhance security. My question is whether you guys hardroll the backend or do u use services like Firebase. However, Firebase is quite expensive, and since it's a non-profit project, I don't have enough funds to support it (I'm using SQLite for the db 💀). I don't anticipate having more than 5,000 users, and I find SQLite easy to use and flexible for starting out. If the user base grows, I can migrate to another database.

The most upvoted open issue on matplotlib: "plot and scatter should allow marker to be a list"

I always find it kind of amazing where on the surface trivial issues in huge libraries can be open after many years. Today I encountered another one:

* [matplotlib#11155: plot and scatter should allow marker to be a list](https://github.com/matplotlib/matplotlib/issues/11155)

What the user wants is very simple: Just being able to input a list of markers, like you input a list of colors or a list of sizes, to give every point another marker.

Implementation wise, that proved a lot more difficult due to matplotlib's internal handeling of markers, labels and other stuff. Interesting read!

Troubleshooting Cloudflare Interception and API Request Failures in Python

I've encountered an issue when making POST requests to certain endpoints using Python's requests library. Cloudflare is intercepting these requests, resulting in a 403 Forbidden error. For endpoint A, I've successfully bypassed Cloudflare using the curl_cffi library. However, endpoint B fails even with curl_cffi, resulting in a connection timeout or SSL handshake error instead of the previous 403.



To clarify:

1. This isn't the typical Cloudflare Challenge Page scenario. The error occurs directly upon POST requests to the API endpoint.

2. All required headers and payload are correctly included in the requests.

3. The original request headers don't contain any Cloudflare-specific parameters; these only appear in the response headers.



I'm seeking advice on how to troubleshoot and resolve this issue, particularly for endpoint B. Any insights into potential workarounds or debugging strategies would be appreciated.

[P] Illustrated book to learn about Transformers & LLMs

I have seen several instances of folks on this subreddit being interested in long-form explanations of the inner workings of Transformers & LLMs.

This is a gap my twin brother and I have been aiming at filling for the past 3 1/2 years. Last week, we published “[Super Study Guide: Transformers & Large Language Models](https://superstudy.guide/transformers-large-language-models/)”, a 250-page book with more than 600 illustrations aimed at visual learners who have a strong interest in getting into the field.

This book covers the following topics in depth:

* **Foundations**: primer on neural networks and important deep learning concepts for training and evaluation.
* **Embeddings**: tokenization algorithms, word embeddings (word2vec) and sentence embeddings (RNN, LSTM, GRU).
* **Transformers**: motivation behind its self-attention mechanism, detailed overview on the encoder-decoder architecture and related variations such as BERT, GPT and T5, along with tips and tricks on how to speed up computations.
* **Large language models**: main techniques to tune Transformer-based models, such as prompt engineering, (parameter efficient) finetuning and preference tuning.
* **Applications**: most common problems including sentiment extraction, machine translation, retrieval-augmented generation and many more.

flask server

Hey guys! Started learning python a couple months back. Made a little chatbot as a project. it got some features like live weather updates, joke of the day and currency conversions.

i wanted to make this chatbot into an interactive website so my friends can interact with it as well. However besides a little HTML, my knowledge on web dev is poor. What should be my next steps to make it into a website?

I tried connecting my backend and front end using a flask server, but when i import my chatbot into my flask server, it starts behaving like the chatbot instead of a web server. Would really appreciate all the advice and ideas
