Are there patterns for receiveing emails within app?
I have no intention of sending emails on my own, I use SES for that, but sometimes it would be convenient if my app could receive emails, e.g. users could reply to messages by replying to email instead of going to app to write message, etc.
So, are there any ways to implement receiving emails using pure python in my flask app? Maybe some type of webhook solution?
I don't want to deal with Postfix or the likes, nor do i want to integrate with an external email provider, so with these reqiurements maybe the answer is no, not possible.

Tool: quickly find the strptime/strftime format code for your date
I appreciate the various strftime cheat sheets floating around online but I've been wanting a tool that'll do the datetime format string construction automatically for a given date/datetime.
So I made a tool to do this: https://pym.dev/strptime
It has a few not-so-obvious features as well. More details in this post, if you're curious.

I made a quick-start template for Flask apps called Create Flask App
Hey everyone!
I made this project called Create Flask App to help you quickly set up and scale your Flask applications. It comes with user authentication (register, login, logout), profile management, and a basic admin page, all styled with Bootstrap 5.3.3. By default, it uses SQLite3, but you can easily configure it to use your preferred database.
Check it out, give it a star if you like it, and let me know what features you'd love to see next and/or feel free to contribute. Your feedback and suggestions would be awesome!
I will keep working on it, adding new features and improvements.

PyAwaitable: An ideal way to define asynchronous logic in C extensions
I've put this idea through a number of discussions (namely, this one and this one) about adding capability to the C API directly to call asynchronous Python code, and I'm officially releasing my reference implementation as a library, per request from the core devs!
## What My Project Does
Put simply, PyAwaitable lets you write and run asynchronous Python functions, from pure C code!
## Target Audience
This project is intended towards those who care a lot about Python performance, or develop C extensions.
## Comparison
As of writing, there are no other libraries that do this. The answer for asynchronous C code has always been: you can't (without a lot of effort, at least -- too much effort for it to be effective).
Most people will defer async logic to a non-async function (think loop.run_until_complete, and friends), and then call that from C.
## Installation
I've developed a stable version, which you can either install off PyPI, or vendor into your project off the releases page: https://github.com/ZeroIntensity/pyawaitable
Feedback, positive or negative, would be appreciated!

Saleor vs Oscar Ecommerce
Hi,
I am currently assessing refactoring a custom lightweight marketplace app built with Nuxt to a proper backend (read Django) to address some of the core pain points usually faced with JS applications (incompatibility between packages, lack of included "batteries", time intensive development etc.)
Saleor and Oscar are the most popular options in the Django ecosystem and I was wondering if people had any experience using one or the other? And what was the overall guideline regarding their usage?
Cheers

Limitations of subprocess?
Are there any limitations as to what `subprocess` can't do or tools that are known to be incompatible with subprocesses?
I am looking to build an IDE that uses subprocesses to launch code in different environments.
For example, I know it is possible for a subprocess to spawn subprocesses.
However, I don't want to get 100 hours into development only to realize something hypothetical like "oh sqlite connections don't support suprocesses" or "you can't spawn [multithreading/multiprocessing\] from subprocess"

Scheduled task
I’ve got some basic flask apps under my belt. But nothing too advanced. I know my projects aren’t set up properly, since it’s based on the basic flask intro tutorial.
I’m planning on building a flask project for one of my clubs to run a giveaway next July. I’d like do pull names / contact info from an API, and every 30 minutes on the day of the giveaway select and text winners from entries submitted since the prior winner selection. I’ve never done anything with scheduled or background tasks.

Sideways Shooter game in Python. Python Crash Course, 3nd Edition.
Hi,
I'm new to programming and decided to pick up Python as first language. I recently completed Python Crash Course by Eric Matthes, and I must say it was a fantastic book.
I had so much fun creating the Alien Invasion game that I ended up making four variations of it.
I'm now moving on to Dead Simple Python to develop my skills while doing some solo projects.

How to handle Blog data
Hey I've been following miguels tutorial and have a few questions:
What is the best way to handle blog data? I want to write multi page articles with gifs / images if possible. I have 2 ideas on how to handle this and wondering what is the generally accepted practice:
1. Create blog table with TEXT as field. Not sure how well it handles formatting like newline characters / whitespace etc. Requires me to then create a form / url and have to be logged into the website to write the articles. Probably easiest solution?
2. Create a directory with markdown files for my articles and have a blog table track the file location and meta data. This means I can write them in markdown somewhere else and don't need to make another form / url for writing them. Issue is how do i keep my db in sync with the blog, if the file names change, meta data changes, etc. Also how would i add new articles once the website it deployed? Copy paste somehow from my local machine to the server?
3. Another way?
Last question, how does rendering markdown work in the browser? Do i have any control over the

Is Learning Django REST Framework (DRF) Worth It?
I've recently started learning Django REST Framework (DRF), and I've noticed that many methods need to be overridden for even simple tasks. This made me wonder, why can't we just create APIs using Django itself? Is creating APIs using Django insecure or what?
I'd love to hear from the community about this. Is DRF worth the extra effort? What are the main advantages of DRF over Django for API development? Any insights or experiences would be greatly appreciated!
Thanks in advance!

Inventory Management for an Antiques Company with Django and Shopify Integration
Hey everyone!
I'm thrilled to share my experience with my 5th Django project for a real client. This time, I worked with an antiques company to build a robust inventory management system integrated with Shopify.
The project revolved around using webhooks from Shopify to keep the inventory up-to-date and QR codes for quick verification of product locations in the warehouse. One of the key challenges was managing products without bin locations. Initially, products without a specified bin location caused inventory discrepancies. To address this, I adjusted the data queries to handle blank spaces and cleaned the data when importing from CSVs to ensure accurate registration of all products.
Another challenge was seamlessly integrating with Shopify's API and implementing QR code functionality. Shopify's API was quite flexible, which made the integration smoother. I used a Python library to generate and read QR codes, allowing for fast and accurate product verification. This significantly reduced human errors and saved a lot of time.
The app's interface was optimized for use on tablets, enabling employees to move freely around the warehouse while checking inventory. This mobility greatly enhanced the efficiency and accuracy of inventory management.
Working on this real project for a real client was incredibly rewarding. Each project

I am getting an error in forms.py specifically the function in functions.py. Put simply the login function form query for the username and email both return None. How do I fix the code?
I am getting an error that no matter how hard I try I can’t solve it. I have located what is causing the error. It is caused by the code in forms.py specifically the function in functions.py. For some reason the query’s are returning None even though in the /register route I added the username and email and password to the db. I am using the same email for the username form and email form before adding them to the db but I don’t think that should make a difference. How do I fix the code?
I think it was working before. Also I plan to pytest the code where the username form and email form are equal then adding them to the db but I decided to post this in case that doesn’t make a difference.
Also I was looking in dbeaver, a database manager, and the columns username and email exists. So I am very confused. I didn’t include all the function but like stated I included the function that is causing the error. Also in the /register route just assume for simplicity I redirected to the /login route instead of where I redirect.

Node Demonstrator - tool to create graphs and show standard algorithms
What my project does
I've been working on a module (largely for myself to use in school) to demonstrate to students, and then for themselves to be able to explore, how graph algorithms work step by step.
It's got to a point where I'm happy enough to share with people, is anyone's interested... I've published it on PyPI here (and it's on GitHub, naturally) so feel free to check it out.
Target Audience
Honestly, this is just a toy project aimed at educational use by A-level teachers (UK), and students
Comparison
It was as much about me building the project and proving that I could use Tkinter (well, ultimately CustomTkinter) and particularly the Canvas to create a drag/drop area for the graph. Haven't really looked at alternatives.

Why is no one using full-stack python for web development? Has no one heard of the FHBH stack ??
Hey guys, I recently came across some libraries that seem to be very interesting to work with for the purpose of creating websites, but I wanted to know why no one uses them, or why they are not so widespread. I haven't had time to develop a more advanced and dynamic project with these libraries yet, but I believe that together they can be extremely useful, powerful and versatile for websites of any purpose. Maybe because no one knows about them, or because there is no benefit in using them and there are better ways to do it, but in a quick project test that I did, the dynamics of working with them seemed very interesting to me.
The libraries that I found were these:
**FastAPI**
A microframework for creating APIs, which can easily be used to create powerful websites.
**HTPY**
HTPY is a library that I recently discovered that was developed by a company that needed a better way to develop their projects with Django and created this library. It encapsulates HTML tags in Python classes, so that all HTML code can be created directly from a Python file, making it possible to use all the power that a programming language offers to generate
