Deploy Your AI Chatbot for FREE with PythonAnywhere! (Step-by-Step Tutorial)
Hey everyone,
If you've built an AI chatbot or any other application with Python but don’t know how to deploy it online, I just released a step-by-step tutorial showing how to do it **for free** using PythonAnywhere.
In the video, I cover:
* Setting up a PythonAnywhere account
* Uploading and running your chatbot on a live server
* Host a Flask web app for your AI chatbot
* Get a public URL to share your chatbot with the world
* Works for chatbots, knowledge bases, and automation scripts
This is perfect if you want to share your chatbot or application with others without paying for hosting.
**Check it out** [YouTube](https://youtu.be/7NtSuPsVcg4)
Would love to hear your thoughts! Have you deployed any AI projects before?

Migrate doesn't detect changes to default values?
According to GPT this is an expected behaviour of Flask. Alembic only detects schema-related changes (column add/remove, renaming...) but doesn't detect for instance if I change a columns default value from NULL to 0. Is this correct?

D ICML 2025 - what if reviewers don't acknowledge rebuttal?
2 out of my 5 reviewers at ICML didn't acknowledge my rebuttal at all. Not only no answer, they also didn't even click the "acknowledge rebuttal" at all. According to ICML rules, they are required to do that. What happens when they don't? Should we report this to AC? I didn't find this anywhere, so maybe someone here knows or is in a similar situation.

Simple REST endpoint with mutliple databases using the same model.
I have a small flask app(learning it AND python) that currently has a single hard coded database. Something LIKE this(not the actual code but semi close)
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI] = 'mysql://user:pass@servername/dbname'
db=SQLAlchemy
class User(db.Model):
__tablename__='someuserstable'
userid = db.Column(db.String(100), primary_key=True)
username = db.Column(db.String(100), nullable=False)
def getjson(self):
return {'userid': self.userid, 'username': self.username}
app.route('/users', methods=['GET']
def get_users():
users = User.query.paginate(page=0, per_page=10)
return jsonify(user.getjson) for user in users
But what I am trying to figure out is how to have it pick the correct connection based on an input on the route. Essentially, I need a map of database connections with. Again, this is more psuedo code and what I am trying to figure out as each connnection will have the same table(s) but different server/username/password/database names(maybe not sure of

Getting same response for "invalid credentials" and "inactive user" using djoser + simpleJWT + Drf
Hey everyone
I'm using Django with Djoser + simple jwt for auth, everything works fine but the endpoints /api/auth/jwt/create return the same response "No active account found with the given credentials" for both when a user enters a wrong email or password and if a user account is not active yet i.e they haven't verified their email. It shows the same error message
I understand it's like a security measure, but it's making it hard for the front end to print the right error message to the user. I have tried customising the TokenCreateSerializer. But it doesn't have an effect on the JWT endpoints. Is there anyone that has experience with this?

Showcase A tarot reading app built in Python with Flask, SQL, and OpenAI — each reading is dynamic
What My Project Does
I built a pixel-art tarot app/game called Mama Nyah’s House of Tarot, where each reading is personalized, story-driven, and dynamically generated based on the user’s intention and cards drawn. Users enter an intention, pull three cards (past, present, future), and the app returns a poetic interpretation written by the OpenAI API.
The experience is meant to feel like stepping into a mystical little tarot parlor in New Orleans.
Target Audience
The project is built for people interested in tarot, storytelling, and immersive digital experiences. While not a full "game," it’s meant to offer a cozy, atmospheric escape or introspection tool. It’s available on Steam, but also served as a learning exercise for me to integrate a Flask backend, persistent user data, and API-driven storytelling.
How It Works / Stack
Python Arcade for game logic and UI
Python + Flask for the backend logic
Render to deploy the app, hold a token limiter, and store reading data
SQL to store user sessions and reading metadata
OpenAI API to generate fresh interpretations based on card combinations and intentions
Aseprite for creating all the pixel art assets
Comparison to Existing Alternatives
Most tarot apps use static card definitions or canned

How many SQL queries per request is too many when each includes SELECT, INSERT, and UPDATE?
I'm handling a backend where every API request triggers about 3–5 SQL queries a mix ofSELECT,INSERT, and UPDATE. These queries operate on individual objects and can't be batched, merged, or prefetched because each one serves a distinct purpose.
Is there a general rule of thumb on how many DB hits per request is too many before it becomes a performance concern?

yt-stats-wrangler - I Created a Python Package for collecting data from YouTube API V3
**What my project does:**
Hey everyone! I work with social media analytics and found myself sourcing data with YouTube API V3 quite often. After looking around for existing wrappers, I thought it would be a fun idea to make my own and deploy it as an open-source package.
So I'm introducing the **yt-stats-wrangler**, which is now available with a simple pip install (see install instructions on links below). Using a google developer key, the package quickly allows you to gather data from the YouTube Data API V3, and then output them into a specified format of your choice. This includes public data and stats on channels, videos and comments.
My goals were as follows:
* Create a modular package that can collect public YouTube data in a logical workflow
* Gather Channels -> Gather videos on channels -> Gather stats for videos -> Gather comments on videos
* Keep the package lightweight and avoid unnecessary dependencies, but offer optional integration of popular data libraries (pandas, polars) for ease of use
This is the first python package that I have ever released. I would love any feedback whether it be in technical implementation, or organizational/documentation structure. I've also attached an MIT license to the

Deploying Containerized Apps to Remote Server Help/Advice (Django, VueJS)
I posted this in r/docker but since it's Django specific I wanted to ask the community here to for help. I have a Django and VueJS app that I've converted into a containerized docker app which also uses docker compose. I have a digitalocean droplet (remote ubuntu server) stood up and I'm ready to deploy this thing. But how do you guys deploy docker apps? Before this was containerized, the way I deployed this app was via a custom ci/cd shell script via ssh I created that does the following:
* Pushes code changes up to git repo for source control
* Builds app and packages the source code
* Stops web servers on the remote server (Gunicorn and nginx)
* Makes a backup of the current site
* Pushes the new site files to the server
* Restarts the web servers (Gunicorn and nginx)
* Done
But what needs to change now that this app is containerized? Can I just simply add a step to restart or rebuild the docker images, if so which one: restart or rebuild and why? What's up with docker registries and image tags? When/how do I use those, and do I even need to?
Apologize in advance if these are monotonous questions but

Compress-py: A CLI to compress files with multiple algorithms
Hello there!
For some time now I've been working on a CLI that offers multiple algorithms to compress and decompress files, and I wanted to share it with you! Here is the Github repository
## What My Project Does:
Tl;DR: You compress stuff with it:
I have implemented Huffman Coding LZW, and RLE without any external compression library. Apart from those compression algorithms, I also implemented the Burrows-Wheeler Transform and Move-To-Front transform to increase compression efficiency.
My project allows you to combine these transformations with the main compression algorithm. If you're not sure which one to choose, I offer a compare-all command, which tests every compression algorithm on a file and provides useful information which will help you choose an algorithm.
Please read the README if you are curious about my implementation, I tried to articulate my choices as much as possible.
## Target Audience:
This was more of a toy project, and is certainly not supposed to be considered 'Production Level'. I wanted to immerse myself in the world of data compression, while refining my python skills.
With that being said, I think I achieved pretty good results, and anyone who wishes to take it for a spin for not-so-serious intentions is welcome.
## Comparison:

Recommended way to manage several installed versions of Python (macOS)
When I use VS Code and select a version of Python on macOS, I have the following versions:
* Python 3.12.8 ('3.12.8') \~/.pyenv/versions/3.12.8/bin/python
* Python 3.13.2 /opt/homebrew/bin/python
* Python 3.12.8 /usr/local/bin/python3
* Python 3.9.6 /Library/Developer/CommandLineTools/usr/bin/python3
* Python 3.9.6 /usr/bin/python3
I believe having this many versions of Python in different locations messes me up when trying to install packages (i.e. using brew vs pip3 vs pyenv), so I'm wondering what the best way is to clean this up and make package + version management easier?

Project - StegH
I'd like to showcase a project I’ve been working on recently.
It’s an image steganography tool that allows you to hide messages inside images securely.
Key features of the tool include:
* **Encrypt & Hide Messages**: Securely hide secret messages inside image files using AES encryption.
* **Platform (Currently Windows-only)**: Right now, it’s available as an executable for Windows.
* **No external dependencies**: Pure Python with minimal libraries such as Pillow, NumPy, and pycryptodome.
**What my project does:** It enables users to securely encrypt and hide messages within images, allowing for private communication. The tool uses AES encryption to ensure the confidentiality of the embedded messages.
**Target audience:** This tool is intended for anyone interested in privacy, security, and steganography, especially developers and enthusiasts exploring encryption techniques.
**Comparison:** This tool isn’t just about encryption; it’s focused on embedding messages into images, which can be shared inconspicuously.
**One last thing:** Quick tip: When sharing an image with a hidden message, be sure to send it as a document (e.g., via WhatsApp's document sharing option). Sending it as a regular image might lead to compression, which could corrupt the hidden data.
Here’s the link to the GitHub repository: [Github](https://github.com/Soham-04/STEGH)

Staticfiles on production server
So I’m trying to deploy my app to my server and is working except it looks ugly (no css, guess no js, etc) I’m ruining my app inside docker and an extra container with nginx. I setup a subdomain for my api and all works well. The api/docs documentation looks fine but the admin pages miss css,etc. I guess I need to hable staticfiles and add it to nginx but what is the way to go regarding this for production environment?

Do you use FastAPI on production?
I've read that FastAPI is used by some big companies, which by themselves have a lot of money and some of the best developers in the world. But down here on earth of poor people, are you (single dev or small company) using FastAPI on production?
It seems like FastAPI is largely developed and maintained by one person (Tiangolo). While he’s done an incredible job, this raises concerns about the project's long-term sustainability. With such a large user base, it’s surprising that there isn’t a bigger core team maintaining it. If Tiangolo were to step away, what happens to FastAPI?
It’s one of the most popular async-first frameworks, but relying on it in production sometimes feels like standing on shifting ground.
I’d love to hear from others working with FastAPI on production.

I wrote on post on why you should start using polars in 2025 based on personal experiences
There has been some discussions about pandas and polars on and off, I have been working in data analytics and machine learning for 8 years, most of the times I've been using python and pandas.
After trying polars in last year, I strongly suggest you to use polars in your next analytical projects, this post explains why.
tldr:
1. faster performance
2. no inplace=true and reset_index
3. better type system
I'm still very new to writing such technical post, English is also not my native language, please let me know if and how you think the content/tone/writing can be improved.

Easily share Python scripts with dependencies (uv + PEP 723)
Sharing single-file Python scripts with external dependencies can be challenging, especially when sharing with people who are less familiar with Python. I wrote a article that made the front page of HN last week on how to use uv and PEP 723 to embed external deps directly into scripts and accomplish the goal.
No more directly messing with virtual environments, requirements.txt, etc. for simple scripts. Perfect for sharing quick tools and utilities. uv rocks! Check it out here.
