What's under your Python app - Postgres, SQLite, MySQL, MariaDB - and why? Yearly database survey

2026-09-22T07:34:58+00:00

Hey, Robert from the MariaDB Foundation here. We run a yearly survey on how people actually use MariaDB, and this year we also want to know in what cases they went with Postgres, SQLite, MySQL or whatever else instead:

https://mariadb.typeform.com/to/tS69UzVo?utm_source=reddit_python

There were a good number of Python and Django users on MariaDB in last year's survey - and a surprising third of them used no ORM at all. What database is under your Python app, and how did it get there? Did you pick it, did the framework default stick, or was it already on the server?

We revamped the questions this year for new insights and split them by role (developer, DBA, operator) to save you time. Nearly 400 answers so far, keep them coming :) Looking forward to reading yours. Anonymous results will be published again at mariadb.org/survey.

Thanks for taking the time!
Cheers, Robert at MariaDB Foundation

Common mistakes devs make when starting with FastAPI, and the fastest path to learning it

2026-09-21T03:43:19+00:00

Just began learning FastAPI. Looking for advice from devs who use it regularly.

What mistakes did you make early on that I should avoid repeating? Also, what's the most efficient way to learn the framework properly for real-world use (async, DB, auth)?

Any advice on structure or resources would be great.

Flet 1.0 released: build desktop, mobile, and web apps in Python

2026-09-16T18:59:49+00:00

I'm the creator of Flet, and we've just released version 1.0 after more than four years of development.

You may have heard of Flet or already be using it. If it's new to you, Flet is an open-source framework for building GUIs in Python. You write the interface and application logic in Python, then package the app for Windows, macOS, Linux, iOS, Android, or the web.

For example, you can put a GUI around a pandas workflow, build a mobile app that processes images with Pillow, or turn a Python script into a desktop application with forms, buttons, and charts.

Here's what we've been working on leading up to 1.0:

Python libraries on your phone

Packaged desktop and mobile apps include CPython, so your Python code runs on the device without needing a separate server. You can bundle Python 3.12, 3.13, or 3.14.

Getting libraries with C and Rust dependencies working on mobile has been a substantial part of the work. We now maintain an index of more than 100 packages and supporting native libraries, including NumPy, pandas, SciPy, Matplotlib, Pillow, scikit-learn, cryptography, and pydantic-core.

Availability varies by package and target. The package list shows what's supported, and the build infrastructure is open source.

Two ways to write your UI

You can create controls and change their properties directly, or use the declarative API to describe the interface from application state. The latter provides state hooks and reusable Python components for organizing larger applications.

Both approaches are supported. Here's a comparison with examples.

Test your app with pytest

You can write tests that launch your packaged app, tap buttons, enter text, and check the resulting UI on desktop or mobile. Tests use pytest, including fixtures and parametrization. On Android and iOS, you can also compare screenshots to catch visual changes.

Integration testing documentation

Faster updates and better packaging

We've improved how Flet calculates UI changes and reduced startup work. In packaged native apps, Python now communicates with the UI runtime within the same process, without sockets. On Android, Python packages can load directly from the APK without being extracted first.

For web apps, Python can run in the browser through Pyodide or on a server through FastAPI/Uvicorn.

Trying it and upgrading

You can try examples and edit Python code in your browser using Flet Studio, or follow the local installation guide for uv or pip.

If you're coming from Flet 0.28, please read the migration guide. Version 1.0 includes breaking API changes and isn't a drop-in replacement.

Flet is licensed under Apache 2.0.

Happy to answer questions about the framework, Python packaging, or running Python libraries on mobile.

dumb question, why not python organizes dependencies as flatpak logic?

2026-09-17T07:02:15+00:00

I have a question that might be really dumb, currently python had went with the environment route to be able to use different libraries that have same dependencies with different versions. i understand that there is a complexity with what i have in mind and not even sure about the feasibility of it. but...

why not instead of having different enviroments where we install the incompatible libraries so 'everyone gets what they need' do something like flatpak style where 'if you have already a version compatible, i do not install this dependency if not i install it again and have the two versions together'. I am not a professional in programming in general, so i might be saying something fully stupid, or not feasible from a technical standpoint.

is it a super dumb idea?

Hello Python Community!

I've been really curious about how Python developers use Python when it comes to webscraping, or just working with websites in general.

I really want to open a discussion on how you do it. Do you use BeautifulSoup? Selenium? Why? Are there any frustrations that you were facing or are currently facing with the process?

does Python run on Batocera-type machines/have any Fantasy Consoles?

does Python run on Batocera-type machines/have any Fantasy Consoles?

i was wondering how well Batocera can run its games, and if there are any Python Fantasy Consoles. Like small handheld gaming machines, but built for running python games specifically. Or any limited sets of limits that restrict what the game or program can do as if it's running on something tiny like the pico-8.

Is dropping support for Python versions 3.8 and 3.9 a breaking change?

2026-09-13T14:43:43+00:00

I am the maintainer of the Python tools for the Polylith Architecture. The main use case is for Microservices in Monorepos, and being able to share code between them in a Developer and Agent-friendly way.

Today, I can see that some Polylith users are running Python versions 3.8 (few) and 3.9 (some) according to the download stats.

Dropping these versions would be mostly a convenience: then I can implement PEP 621 internally, and bump subdependencies. It's not an urgent task, but something that I probably should do during 2026.

The Polylith project is releasing new versions according to semantic versioning, and dropping support would probably be a Breaking feature - even if the Python versions themselves are unsupported since quite a while. I hesitate how to approach this, because I don't want to cause disruptions in the flow of the Developer Teams out there.

I know that the "big" tools in the Python community handle this in different ways. Such as FastAPI and Typer, dropping 3.8 and 3.9 support without a Major version change (I guess they don't use semantic versioning?).

Bumping the Major version could make teams miss out on new versions if they pin the tool to the current version. I also know how I usually react to a new Major version for tools I use on a daily basis:

"What do we need to change on our end to make this new version of the library/tool work?"

Bumping the minor version would break the builds for those running on Python 3.8 and 3.9 users, unless they already pin the tool to a specific version.

What would be the best way to go forward here?

Appreciation to Hynek Schlawack

2026-09-12T16:48:02+00:00

This guy is kind of my mentor in Python and open-source. He definitely loves programming. He has been an importtant Python core maintainer, and published some successful libraries like attrs and structlog for improving codebases legibility and structure, he also has a high value series in his youtube channel about how to package python applications in a extremely clean way by using uv (https://www.youtube.com/watch?v=mFyE9xgeKcA).

What I also love from him is his minimalism and simplicity. In a world of tones of lines of AI-generated code per-day, he has recently published pgbg, a new python library consisting in 7 files, very little code, that emerges from a deep understanding of how background processing works in python and the gaps on it. These type of low-abstraction level projects are the ones on which tones of big projects rely. Definitely highly valuable.
