Add your name and email to our friends of the show list , we'll never share it. Brian #1: pypistats.org was down, is now back, and there’s a CLI pypistats.org is a cool site to check the download stats for Python packages. It was down for a while , like 3 weeks? A couple days ago, Hugo van Kemenade announced that it was back up . With some changes in stewardship “ pypistats.org is back online! 🚀📈 Thanks to @jezdez for suggesting the @ThePSF takes stewardship and connecting the right people, to @EWDurbin for migrating, and of course to Christopher Flynn for creating and running it for all these years!” Hugo has a CLI version, pypistats You can give it a command for what you want to search for recent,overall, python_major, python_minor, system Then either a package name, a directory path, or if nothing, it will grab the current directory package via pyproject.toml or setup.cfg very cool Michael #2: State of Python 2025 Michael’s Themes Python people use Python: 86% of respondents use Python as their main language We are mostly brand-new programmers: Exactly 50% of respondents have less than two years of professional coding experience Data science is now over half of all Python Most still use older Python versions despite benefits of newer releases: Compelling math to make the change . Python web devs resurgence Forward-looking trends Agentic AI will be wild Async, await, and threading are becoming core to Python Python GUIs and mobile are rising Actionable ideas Action 1: Learn uv Action 2: Use the latest Python Action 3: Learn agentic AI Action 4: Learn to read basic Rust Action 5: Invest in understanding threading Action 6: Remember the newbies Brian #3: wrapt: A Python module for decorators, wrappers and monkey patching. “The aim of the wrapt module is to provide a transparent object proxy for Python, which can be used as the basis for the construction of function wrappers and decorator functions. An easy to use decorator factory is provided to make it simple to create your own decorators that will behave correctly in any situation they may be used.” Why not just use functools.wraps() ? “The wrapt module focuses very much on correctness. It therefore goes way beyond existing mechanisms such as functools.wraps() to ensure that decorators preserve introspectability, signatures, type checking abilities etc. The decorators that can be constructed using this module will work in far more scenarios than typical decorators and provide more predictable and consistent behaviour.” There’s a bunch of blog posts from 2014 / 2015 (and kept updated) that talk about how wrapt solves many issues with traditional ways to decorate and patch things in Python, including “How you implemented your Python decorator is wrong” . Docs are pretty good, with everything from simple wrappers to an example of building a wrapper to handle thread synchronization Michael #4: pysentry via Owen Lamont Install via uv tool install pysentry-rs Scan your Python dependencies for known security vulnerabilities with Rust-powered scanner. PySentry audits Python projects for known security vulnerabilities by analyzing dependency files ( uv.lock , poetry.lock , Pipfile.lock , pyproject.toml , Pipfile , requirements.txt ) and cross-referencing them against multiple vulnerability databases. It provides comprehensive reporting with support for various output formats and filtering options. Key Features : Multiple Project Formats : Supports uv.lock , poetry.lock , Pipfile.lock , pyproject.toml , Pipfile , and requirements.txt files External Resolver Integration : Leverages uv and pip-tools for accurate requirements.txt constraint solving Multiple Data Sources : PyPA Advisory Database (default) PyPI JSON API OSV.dev (Open Source Vulnerabilities) Flexible Output for different workflows : Human-readable, JSON, SARIF, and Markdown formats Performance Focused : Written in Rust for speed Async/concurrent processing Multi-tier intelligent caching (vulnerability data + resolved dependencies) Comprehensive Filtering : Severity levels (low, medium, high, critical) Dependency scopes (main only vs all [optional, dev, prod, etc] dependencies) Direct vs. transitive dependencies Enterprise Ready : SARIF output for IDE/CI integration I tried it on pythonbytes.fm and found only one issue, sadly can’t be fixed: PYSENTRY SECURITY AUDIT ======================= SUMMARY: 89 packages scanned • 1 vulnerable • 1 vulnerabilities found SEVERITY: 1 LOW UNFIXABLE: 1 vulnerabilities cannot be fixed VULNERABILITIES --------------- 1.

Add your name and email to our friends of the show list , we'll never share it. Michael #1: pyx - optimized backend for uv via John Hagen (thanks again) I’ll be interviewing Charlie in 9 days on Talk Python → Sign up (get notified) of the livestream here . Not a PyPI replacement, more of a middleware layer to make it better, faster, stronger. pyx is a paid service, with maybe a free option eventually. Brian #2: Litestar is worth a look James Bennett Michael brought up Litestar in episode 444 when talking about rewriting TalkPython in Quart James brings up scaling - Litestar is easy to split an app into multiple files Not using pydantic - You can use pydantic with Litestar, but you don’t have to. Maybe attrs is right for you instead. Michael brought up Litestar seems like a “more batteries included” option. Somewhere between FastAPI and Django. Brian #3: Django remake migrations Suggested by Bruno Alla on BlueSky In response to a migrations topic last week django-remake-migrations is a tool to help you with migrations and the docs do a great job of describing the problem way better than I did last week “The built-in squashmigrations command is great, but it only work on a single app at a time, which means that you need to run it for each app in your project. On a project with enough cross-apps dependencies, it can be tricky to run.” “This command aims at solving this problem, by recreating all the migration files in the whole project, from scratch, and mark them as applied by using the replaces attribute. ” Also of note The package was created with Copier Michael brought up Copier in 2021 in episode 219 It has a nice comparison table with CookieCutter and Yoeman One difference from CookieCutter is yml vs json. I’m actually not a huge fan of handwriting either. But I guess I’d rather hand write yml. So I’m thinking of trying Copier with my future project template needs. Michael #4: django-chronos Django middleware that shows you how fast your pages load, right in your browser. Displays request timing and query counts for your views and middleware. Times middleware, view, and total per request (CPU and DB).

Add your name and email to our friends of the show list , we'll never share it. Brian #1: Coverage.py regex pragmas Ned Batchelder The regex implementation of how coverage.py recognizes pragmas is pretty amazing. It’s extensible through plugins covdefaults adds a bunch of default exclusions, and also platform- and version-specific comment syntaxes. coverage-conditional-plugin gives you a way to create comment syntaxes for entire files, for whether other packages are installed, and so on. A change from last year (as part of coverage.py 7.6 allows multiline regexes, which let’s us do things like: Exclude an entire file with \\A(?s:.*# pragma: exclude file.*)\\Z Allow start and stop delimiters with # no cover: start(?s:.*?)# no cover: stop Exclude empty placeholder methods with ^\\s*(((async )?def .*?)?\\)(\\s*->.*?)?:\\s*)?\\.\\.\\.\\s*(#|$) See Ned’s article for explanations of these Michael #2: Python of Yore via Matthias Use YORE: ... comments to highlight CPython version dependencies. # YORE: EOL 3.8: Replace block with line 4. if sys . version_info < ( 3 , 9 ): from astunparse import unparse else : from ast import unparse Then check when they go out of support: $ yore check --eol-within '5 months' ./src/griffe/agents/nodes/_values.py:11: Python 3 .8 will reach its End of Life within approx. 4 months Even fix them with fix . Michael #3: nox-uv via John Hagen What nox-uv does is make it very simple to install uv extras and/or dependency groups into a nox session's virtual environment. The versions installed are constrained by uv's lockfile meaning that everything is deterministic and pinned. Dependency groups make it very easy to install only want is necessary for a session (e.g., only linting dependencies like Ruff, or main dependencies + mypy for type checking). Brian #4: A couple Django items Stop Using Django's squashmigrations: There's a Better Way Johnny Metz Resetting migrations is sometimes the right thing. Overly simplified summary: delete migrations and start over dj-lite Adam Hill Use SQLite in production with Django “Simplify deploying and maintaining production Django websites by using SQLite in production. dj-lite helps enable the best performance for SQLite for small to medium-sized projects.

The existing solution had been a complicated two-step process of creating obscure .pth files and setting environment variables. Whole projects appeared on PyPI to handle this for you.” From release notes for 7.10.0 A new configuration option: “[run] patch” specifies named patches to work around some limitations in coverage measurement. These patches are available: patch = _exit lets coverage save its data even when os._exit() is used to abruptly end the process. This closes long-standing issue 310 as well as its duplicates: issue 312 , issue 1673 , issue 1845 , and issue 1941 . patch = subprocess measures coverage in Python subprocesses created with subprocess , os.system() , or one of the execv or spawnv family of functions. Closes old issue 367 and duplicate issue 378 . patch = execv adjusts the execv family of functions to save coverage data before ending the current program and starting the next. Not available on Windows. Closes issue 43 after 15 years! Michael #3: aioboto3 via Pat Decker Wrapper to use boto3 resources with the aiobotocore async backend aiobotocore allows you to use near enough all of the boto3 client commands in an async manner just by prefixing the command with await . With aioboto3 you can now use the higher level APIs provided by boto3 in an asynchronous manner. Brian #4: You might not need a Python class Adam Grant This is an important periodic reminder to everyone coming into Python from other languages. Many other languages lean on classes a lot more than we need to in Python Adams suggestions Simple Data Containers: Use Named Tuples or Data Classes Stateless Utility Functions: Just Use Functions Grouping Constants: Use Modules Managing State with Simple Structures: Use Dictionaries or Lists Simple One-off Operations: Use Lambdas or Comprehensions I’ll add “just use functions” Avoiding Complexity: Built-in Libraries When You Actually Need a Class I’ll add You probably don’t If you think you do, ask a friend.

Add your name and email to our friends of the show list , we'll never share it. Brian #1: Open Source Security work isn't “Special” Seth Larson It seems like security is special in a sense that we don’t want just anyone working on the security aspect of a project. We just want the trusted maintainers, right? Seth is arguing that this is the wrong mindset It makes more sense that we maybe have security experts contribute to many projects, and that someone working on security for just one project doesn’t benefit from scale. “Maintainers don’t see how other projects are triaging vulnerabilities and can’t learn from each other. They can’t compare notes on what they are seeing and whether they are doing the right thing. Isolation in security work breeds a culture of fear. Fear of doing the wrong thing and making your users unsafe.” “These “security contributors” could be maintainers or contributors of other open source projects that know about security, they could be foundations offering up resources to their ecosystem, or engineers at companies helping their dependency graph.” But how do we build trust in these individuals? Meeting in person works. But there are other ways as well. I’d personally love to have someone contact me about a project of mine regarding a security problem or process that the project could/should follow. Especially if I could see other projects I trust already trusting this individual to work on the other projects.

Brian #1: Switching to direnv, Starship, and uv Last week I mentioned that I’m ready to try direnv again, but secretly, I still had some worries about the process. Thankfully, Trey has a tutorial to walk me past the troublesome parts. direnv - an extension for your shell. It augments existing shells with a new feature that can load and unload environment variables depending on the current directory. Switching from virtualenvwrapper to direnv, Starship, and uv - Trey Hunner** Trey has solved a bunch of the problems I had when I tried direnv before Show the virtual environment name in the prompt Place new virtual environments in local .venv instead of in .direnv/python3.12 Silence all of the “loading”, “unloading” statements every time you enter a directory Have a script called venv to create an environment, activate it, create a .envrc file I’m more used to a create script, so I’ll stick with that name and Trey’s contents A workon script to be able to switch around to different projects. This is a carry over from “virtualenvwrapper’, but seems cool. I’ll take it. Adding uv to the mix for creating virtual environments. Interestingly including --seed which, for one, installs pip in the new environment. (Some tools need it, even if you don’t) Starship Trey also has some setup for Starship. But I’ll get through the above first, then MAYBE try Starship again. Some motivation Trey’s setup is pretty simple. Maybe I was trying to get too fancy before Starship config in toml files that can be loaded with direnv and be different for different projects. Neato Also, Trey mentions his dotfiles repo. This is a cool idea that I’ve been meaning to do for a long time. See also: It's Terminal - Bootstrapping With Starship, Just, Direnv, and UV - Mario Munoz Michael #2: rqlite - Distributed SQLite DB via themlu, thanks ! rqlite is a lightweight, user-friendly, distributed relational database built on SQLite. Built on SQLite, the world’s most popular database Supports full-text search, Vector Search, and JSON documents Access controls and encryption for secure deployments Michael #3 : A Python dict that can report which keys you did not use by Peter Bengtsson Very cool for testing that a dictionary has been used as expected (e.g. all data has been sent out via an API or report). Note: It does NOT track d.get(), but it’s easy to just add it to the class in the post. Maybe someone should polish it up and put it on pypi (that person is not me :) ). Brian #4: Some Markdown Stuff Textual 4.0.0 adds Markdown.append which can be used to efficiently stream markdown content The reason for the major bump is due to an interface change to Widget.anchor Refreshing to see a symantic change cause a major version bump. html-to-markdown Converts html to markdown A complete rewrite fork of markdownify Lots of fun features like “streaming support” Curious if it can stream to Textual’s Markdown.append method. hmmm.

Add your name and email to our friends of the show list , we'll never share it. Michael #1: ty documentation site and uv migration guide via Skyler Kasko Astral created a documentation site for ty (PR #744 in release 0.0.1-alpha.13 ). Astral added a page on migrating from pip to a uv project in the uv documentation. (PR #12382 in release 0.7.19 ). Talk Python episode on ty . Brian #2: uv build backend is now stable + other Astral news The uv build backend is now stable Tim Hopper via Python Developer Tooling Handbook From Charlie Marsh “The uv build backend is now stable, and considered ready for production use. An alternative to setuptools, hatchling, etc. for pure Python projects, with a focus on good defaults, user-friendly error messages, and performance. When used with uv, it's 10-35x faster.” “(In a future release, we'll make this the default.)” [build-system] requires = [ "uv_build>=0.7.19,<0.8.0" ] build-backend = "uv_build" I believe it’s faster, but I agree with Brett Canno n in asking “What's being benchmarked? I'm not sure what a "backend sync" is referring to other than maybe installing the build back-end?” See also: uv: Making Python Local Workflows FAST and BORING in 2025 - Hynek Brian #3: Refactoring long boolean expressions Trey Hunner This is applied boolean logic, and even folks who learned this in a CS program probably did so early on, and may have forgotten it. How can you improve the readability of long Boolean expressions in Python? Put parens around the whole expression and separate clauses onto different lines Where to put boolean operators between clauses? at the end of the line or the beginning? PEP8 recommends the beginning if ( expression1 and expression2 and expression3 ): ... Naming sub-expressions with variables Odd downside that wouldn’t occur to me. All expressions are evaluated, thus not taking advantage of expression short-circuiting. Naming operations with functions Less readable, but takes advantage of short-circuiting Using De Morgan’s Law : replacing a compound expression with a similar (and hopefully easier to read) expression # neither: we want both to be false not ( a or b ) == ( not a ) and ( not b ) # never_both: at least one false not ( a and b ) == ( not a ) or ( not b ) Michael #4: fastapi-ml-skeleton FastAPI Skeleton App to serve machine learning models production-ready. This repository contains a skeleton app which can be used to speed-up your next machine learning project. The code is fully tested and provides a preconfigured tox to quickly expand this sample code. A sample regression model for house price prediction is included in this project. Short write up on " What does set -a do? " Extras Brian: OCF Michael: via Wei Lee Extra Airflow ruff rules: Starting from Ruff version 0.11.13, most changes from Airflow 2 to Airflow 3 can be automated using AIR3. (It’s still in preview so a “—-preview” flag is needed) e.g., if you have the following Airflow 2 code import datetime from airflow.models import DAG from airflow.operators.empty import EmptyOperator with DAG ( dag_id = "my_dag_name" , start_date = datetime . datetime ( 2021 , 1 , 1 ), schedule_interval = "@daily" , ): EmptyOperator ( task_id = "task" ) it can be fixed with uvx ruff check --select AIR3 --fix --unsafe-fixes --preview import datetime from airflow.sdk import DAG from airflow.providers.standard.operators.empty import EmptyOperator with DAG ( dag_id = "my_dag_name" , start_date = datetime . datetime ( 2021 , 1 , 1 ), schedule = "@daily" , ): EmptyOperator ( task_id = "task" ) which works with Airflow 3.

Use their affordable cloud solution or self-host on your own servers. Automatisch allows you to store your data on your own servers, good for companies dealing with sensitive user data, particularly in industries like healthcare and finance, or those based in Europe bound by General Data Protection Regulation (GDPR). Michael #3: mureq-typed Single file, zero-dependency alternative to requests. Fully typed. Modern Python tooling. Typed version of mureq (covered in 2022 on episode 268) Intended to be vendored in-tree by Linux systems software and other lightweight applications. mureq-typed is a drop-in, fully API compatible replacement for mureq updated with modern Python tooling: Type checked with mypy, ty, and pyrefly. Formatted with black, no ignore rules necessary. Linted with ruff (add these rules for mureq.py to your per-file-ignores ).

Even if your setter accepts different types, the type checker will complain on assignment.” Will describes a way to get around this and make type checkers happy. He replaces @property with a descriptor. It’s a cool technique. I also like the way Will is allowing different ways to use a property such that it’s more convenient for the user. This is a cool deverloper usability trick. Brian #3: complexipy Calculates the cognitive complexity of Python files, written in Rust. Based on the cognitive complexity measurement described in a white paper by Sonar Cognitive complexity builds on the idea of cyclomatic complexity. Cyclomatic complexity was intended to measure the “testability and maintainability” of the control flow of a module. Sonar argues that it’s fine for testability, but doesn’t do well with measuring the “maintainability” part. So they came up with a new measure. Cognitive complexity is intended to reflects the relative difficulty of understanding, and therefore of maintaining methods, classes, and applications. complexipy essentially does that, but also has a really nice color output. Note: at the very least, you should be using “cyclomatic complexity” try with ruff check --select C901 But also try complexipy. Great for understanding which functions might be ripe for refactoring, adding more documentation, surrounding with more tests, etc. Michael #4: juvio uv kernel for Jupyter ⚙️ Automatic Environment Setup: When the notebook is opened, Juvio installs the dependencies automatically in an ephemeral virtual environment (using uv ), ensuring that the notebook runs with the correct versions of the packages and Python 📁 Git-Friendly Format: Notebooks are converted on the fly to a script-style format using # %% markers, making diffs and version control painless Why Use Juvio?

Topics covered in this episode: * Free-threaded Python no longer “experimental” as of Python 3.14 * typed-ffmpeg pyleak * Optimizing Test Execution: Running live_server Tests Last with pytest * Extras Joke Watch on YouTube About the show Sponsored by PropelAuth : pythonbytes.fm/propelauth66 Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience.

Add your name and email to our friends of the show list , we'll never share it. Brian #1: Free-threaded Python no longer “experimental” as of Python 3.14 “PEP 779 ("Criteria for supported status for free-threaded Python") has been accepted, which means free-threaded Python is now a supported build!” - Hugo van Kemenade PEP 779 – Criteria for supported status for free-threaded Python As noted in the discussion of PEP 779 , “The Steering Council (SC) approves PEP 779, with the effect of removing the “experimental” tag from the free-threaded build of Python 3.14.” We are in Phase II then. “We are confident that the project is on the right path, and we appreciate the continued dedication from everyone working to make free-threading ready for broader adoption across the Python community.” “Keep in mind that any decision to transition to Phase III, with free-threading as the default or sole build of Python is still undecided, and dependent on many factors both within CPython itself and the community. We leave that decision for the future.” How long will all this take? According to Thomas Wouters, a few years, at least : “In other words: it'll be a few years at least. It can't happen before 3.16 (because we won't have Stable ABI support until 15) and may well take longer.” Michael #2: typed-ffmpeg typed-ffmpeg offers a modern, Pythonic interface to FFmpeg, providing extensive support for complex filters with detailed typing and documentation. Inspired by ffmpeg-python, this package enhances functionality by addressing common limitations, such as lack of IDE integration and comprehensive typing, while also introducing new features like JSON serialization of filter graphs and automatic FFmpeg validation. Features : Zero Dependencies: Built purely with the Python standard library, ensuring maximum compatibility and security. User-Friendly: Simplifies the construction of filter graphs with an intuitive Pythonic interface. Comprehensive FFmpeg Filter Support: Out-of-the-box support for most FFmpeg filters, with IDE auto-completion. Integrated Documentation: In-line docstrings provide immediate reference for filter usage, reducing the need to consult external documentation. Robust Typing: Offers static and dynamic type checking, enhancing code reliability and development experience. Filter Graph Serialization: Enables saving and reloading of filter graphs in JSON format for ease of use and repeatability. Graph Visualization: Leverages graphviz for visual representation, aiding in understanding and debugging. Validation and Auto-correction: Assists in identifying and fixing errors within filter graphs. Input and Output Options Support: Provide a more comprehensive interface for input and output options, including support for additional codecs and formats. Partial Evaluation: Enhance the flexibility of filter graphs by enabling partial evaluation, allowing for modular construction and reuse. Media File Analysis: Built-in support for analyzing media files using FFmpeg's ffprobe utility, providing detailed metadata extraction with both dictionary and dataclass interfaces. Michael #3: pyleak Detect leaked asyncio tasks, threads, and event loop blocking with stack trace in Python. Inspired by goleak. Use as context managers or function dectorators When using no_task_leaks, you get detailed stack trace information showing exactly where leaked tasks are executing and where they were created. Even has great examples and a pytest plugin. Brian #4: Optimizing Test Execution: Running live_server Tests Last with pytest Tim Kamanin “When working with Django applications, it's common to have a mix of fast unit tests and slower end-to-end (E2E) tests that use p ytest 's live_server fixture and browser automation tools like Playwright or Selenium . ” Tim is running E2E tests last for Faster feedback from quick tests To not tie up resources early in the test suite. He did this with custom “e2e” marker Implementing a pytest_collection_modifyitems hook function to look for tests using the live_server fixture, and for them automatically add the e2e marker to those tests move those tests to the end The reason for the marker is to be able to Just run e2e tests with -m e2e Avoid running them sometimes with -m "not e2e" Cool small writeup. The technique works for any system that has some tests that are slower or resource bound based on a particular fixture or set of fixtures.
