Whatever happened to "explicit is better than implicit"?
I'm making an app with FastAPI and PyTest, and it seems like everything relies on implicit magic to get things done.
With PyTest, it magically rewrites the bytecode so that you can use the built in assert statement instead of custom methods. This is all fine until you try and use a helper method that contains asserts and now it gets the line numbers wrong, or you want to make a module of shared testing methods which won't get their bytecode rewritten unless you remember to ask pytest to specifically rewrite that module as well.
Another thing with PyTest is that it creates test classes implicitly, and calls test methods implicitly, so the only way you can inject dependencies like mock databases and the like is through fixtures. Fixtures are resolved implicitly by looking for something in the scope with a matching name. So you need to find somewhere at global scope where you need to stick your test-only dependencies and somehow switch off the production-only dependencies.
FastAPI is similar. It has 'magic' dependencies which it will try and resolve based on the identifier name when the path function is called, meaning that if those dependencies should be configurable, then you need to

Discussion Non compute hungry research publications that you really liked in the recent years?
There are several pieces of fantastic works happening all across the industry and academia. But greater the hype around a work more resource/compute heavy it generally is.
What about some works done in academia/industry/independently by a small group (or single author) that is really fundamental or impactful, yet required very little compute (a single or double GPU or sometimes even CPU)?
Which works do you have in mind and why do you think they stand out?

🐶 immunipy: Find vulnerable dependencies in your Python projects
# What My Project Does
I've created immunipy a Python SCA tool that acts as a watchdog, keeping an eye out for security vulnerabilities and reporting them promptly, written in Rust. immunipy will scan your requirements.txt or poetry.lock files and search for existing vulnerabilities in your dependencies, if any of your dependencies is reported as vulnerable then you will get the information, such as: package, version, fixed version (if exists), vuln id, aliases and the location.
It's easy to use and is really fast, all the vulnerabilities are reported in real time.
# Target Audience
I think that immunipy is useful for every project, specially the production ready ones, due that every time that you run it you will get an instant scan of your dependencies.
# Comparison
It's easy to use, just pip install immunipy and you can run it! Also, you can add it in your CI/CD pipeline and run it regularly, this is useful if you want to keep your projects free of vulnerable dependencies.

Do you feel like Python's type hinting got "stable"?
Basically the title.
I was reading through [https://docs.python.org/3.13/library/typing.html](https://docs.python.org/3.13/library/typing.html) and noticed that quite a lot happened over the last few years. Doing a text search for `deprecated since version x` with `x` being one of `3.9` to `3.13` I found these according numbers of occurrences:
* `3.9` -> 37
* `3.10` -> 0
* `3.11` -> 1
* `3.12` -> 3
* `3.13` -> 5
Which makes me question how "stable" Python type hinting has become these days. Do you think that there are still rough edges that need major overhauls or is Python 3.13 actually mostly where we need it to be in order to productively use static typing?

I created a command line tool using Python and Ollama to automatically create PRs on GitHub
Hey everybody!
# What My Project Does
I created this command line tool called jit that analyses your diffs and commit messages to generate a pull request description (based on your project's PR template if it has one) and then creates a pull request on GitHub (draft by default) using GitHub CLI.
# Target Audience
This tool is meant for developers that use GitHub. Mostly meant for hobby projects, but if you want you can use it on a production project (for work/clients) because:
* it utilizes a local LLM (no sharing your code to 3rd party APIs)
* The pull requests follow the template specified in your repository
* The pull request is marked as draft by default
# Comparison
I have not found any cli tools that do this in this manner. But I think GitHub's Copilot for Pull Requests will certainly generate better descriptions: [https://githubnext.com/projects/copilot-for-pull-requests/](https://githubnext.com/projects/copilot-for-pull-requests/)
# More about me and jit
I am predominantly a full-stack web developer (React, NestJS) for my job, but I love playing around with Python and other things. I have developed this using Python and Ollama with llama3.
I have been using jit almost every day, for about a month now, and it has made such a big difference in my day-to-day as a

Giving the option to the user of allowing concurrent login

UXsim 1.4.0 released, with a ~20x speedup over 1.3.0 for large scale traffic scenarios
Version 1.4.0 of UXsim is released, which optimized two shortest path search functions by using better suited data formats (matrices where possible) and vectorization, for a \~20x speedup over 1.3.0. See:
[https://github.com/toruseo/UXsim/issues/53](https://github.com/toruseo/UXsim/issues/53)
https://github.com/toruseo/UXsim/issues/84
UXsim 1.4.0 highlights
Significant speed up for large-scale scenario
In combination with the previous v1.3.1 update, we have optimized the shortest path search and related functions. As a result, the calculation speed for large scenarios (e.g., those with 1000+ links) has increased by 10 to 100 times.
Implement new scenario writing/reading functions `W.save_scenario` and `W.load_scenario`.
As a demonstration of these updates, we have added demo in Chicago-Sketch dataset with 1 million vehicles.
UXsim
UXsim is a free, open-source macroscopic and mesoscopic network traffic flow simulator written in Python. It simulates the movements of car travelers and traffic congestion in road networks. It is suitable for simulating large-scale (e.g., city-scale) traffic phenomena. UXsim is especially useful for scientific and educational purposes because of its simple, lightweight, and customizable features, but users are free to use UXsim for any purpose.

Is django (+ htmx) the right thing for me?
Hi everybody!
I'm coming from the data science python path. Long time ago I learned html and css - builded some static websites while studying but never got really into it - a little bit of bootstrap, jquery or wordpress on top was all I needed.
Now I want to build a website where different users can access different dashboards. After processing the data from different sources, it will be stored in a postgres database from where I want to access the data with django and build some dashboards for different use cases and users.
Furthermore I want to create some questionnaires where users have to log in and answer in predefined intervalls and store these values in my database too.
Most of my visualizations I do with matplotlib, seaborn and vega-altair in streamlit apps for now, but I don't like being limited by streamlit anymore. And my projects are getting bigger.
So I am searching a framework to learn which meets my needs.
Can you recommend django + htmx to me in good conscience?
Should I take the effort and learn a javascript framework?
Thank you for your thoughts!

Django seems like a full-stack framework as opposed to a back-end framework, Is it right for me if I'm looking for a back-end framework?
Title basically sums it up. I wanna get into Django but the tutorials I've seen so far make it seem like it's more of a full-stack framework, and this is making it really difficult for me to know what I'm learning?
I plan on using it with frameworks like React, HTML, CSS, Next.js and more.
This might be a dumb question but I really need to know. Thanks!

How to pass context to render_template?
Hi,
I use Flask with htmx. In case its a normal request, I call `render_template` as usual. But in case the request is coming from htmx, I want to return only a part of the template.
I've created two templates each time I need to return either or.
```jinja2
# login.html
{% extends "base.html" %}
{% block main %}
{% include "login_form.html" %}
{% endblock main %}
```
```jinja2
# login_form.html
<form>
...
</form>
```
In my route I can easily do:
```python
from flask import render_template
if htmx: template = "login_form.html"
else: template = "login.html"
return render_template(template, ...)
```
Now I came across [Jinja2-Fragments](https://github.com/sponsfreixes/jinja2-fragments) which allows to render only individual blocks of a template. That means I wouldn't have to create the wrapper templates, which would be desirable.
Problem is, I now end up with something like:
```python
from flask import render_template
from jinja2_fragments.flask import render_block
if htmx: return render_block("login.html", "main", ...)
else: return render_template("login.html", ...)
```
Okay, cool. But if I pass n variables as context to the template, I have to repeat those in both function calls. Not exactly DRY.
I could create a dict like `vars = {"var1": var1, "var2": var2, ...}` and pass that to both function calls, but then in the template I need to prefix all variables with `vars.var1` which is not so pretty either.
