Add your name and email to our friends of the show list, we'll never share it. Brian #1: pre-commit: install with uv Adam Johnson uv tool works great at keeping tools you use on lots of projects up to date quickly, why not use it for pre-commit. The extension of pre-commit-uv will use uv to create virtual environments and install packages fore pre-commit. This speeds up initial pre-commit cache creation. However, Adam is recommending this flavor of using pre-commit because it's just plain easier to install pre-commit and dependencies than the official pre-commit install guide. Win-win. Side note: No Adam, I'm not going to pronounce uv “uhv”, I'll stick with “you vee”, even Astral tells me I'm wrong Michael #2: PEP 773: A Python Installation Manager for Windows (Accepted) via pycoders newsletter One manager to rule them all – PyManager. PEP 773 replaces all existing Windows installers (.exe “traditional” bundle, per-version Windows Store apps, and the separate py.exe launcher) with a single MSIX app called Python Install Manager (nick-named PyManager). PyManager should be mainstream by CPython 3.15, and the traditional installer disappears no earlier than 3.16 (≈ mid-2027). Simple, predictable commands. python → launches “the best” runtime already present or auto-installs the latest CPython if none is found. py → same launcher as today plus management sub-commands: py install, py uninstall, py list, py exec, py help. Optional python3 and python3.x aliases can be enabled by adding one extra PATH entry. Michael #3: Changes for Textual Bittersweet news: the business experiment ends, but the code lives on. Textual began as a hobby project layered on top of Rich, but it has grown into a mature, “makes-the-terminal-do-the-impossible” TUI framework with an active community and standout documentation. Despite Textual's technical success, the team couldn't pinpoint a single pain-point big enough to sustain a business model, so the company will wind down in the coming weeks. The projects themselves aren't going anywhere: they're stable, battle-tested, and will continue under the stewardship of the original author and the broader community. Brian #4: The Best Programmers I Know Matthias Endler “I have met a lot of developers in my life. Lately, I asked myself: “What does it take to be one of the best? What do they all have in common?”” The list Read the reference Know your tools really well Read the error message Break down problems Don't be afraid to get your hands dirty Always help others Write Never stop learning Status doesn't matter Build a reputation Have patience Never blame the computer Don't be afraid to say “I don't know” Don't guess Keep it simple Each topic has a short discussion. So don't just ready the bullet points, check out the article. Extras Brian: I had a great time in Munich last week. I a talk at a company event, met with tons of people, and had a great time. The best part was connecting with people from different divisions working on similar problems. I love the idea of internal conferences to get people to self organize by topic and meet people they wouldn't otherwise, to share ideas. Also got started working on a second book on the plane trip back. Michael: Talk Python Clips (e.g. mullet) Embrace your cloud firewall (example).

What's New In Python 3.13 Interpreter (REPL) improvements exit works (really, this is worth the release right here) Multiline editing with history preservation. history sticks around between sessions Direct support for REPL-specific commands like help, exit, and quit, without the need to call them as functions. Prompts and tracebacks with color enabled by default. Interactive help browsing using F1 with a separate command history. History browsing using F2 that skips output as well as the >>> and … prompts. “Paste mode” with F3 that makes pasting larger blocks of code easier (press F3 again to return to the regular prompt). exit now works without parens Improved error messages Colorful tracebacks Better messages for naming a script/module the same name as a stdlib module. naming a script/module the same name as an installed third party module. misspelling a keyword argument Free threaded CPython Included in official installers on Windows and macOS Read these links to figure out how - it's not turned on by default Lot's more. see the What's new page Michael #2: PEP 759 – External Wheel Hosting pypi.org ships over 66 petabytes / month backed by Fastly There are hard project size limits for publishers to PyPI We can host the essence of a .whl as a .rim file, then allow an external download URL Security: Several factors as described in this proposal should mitigate security concerns with externally hosted wheels, such as: Wheel file checksums MUST be included in .rim files, and once uploaded cannot be changed. Since the checksum stored on PyPI is immutable and required, it is not possible to spoof an external wheel file, even if the owning organization lost control of their hosting domain. Externally hosted wheels MUST be served over HTTPS. In order to serve externally hosted wheels, organizations MUST be approved by the PyPI admins. Brian #3: pytest-freethreaded PyCon JP 2024 Team: This extension was created at PyCon JP sprints with Anthony Shaw and 7 other folks listed in credits. “A pytest plugin for helping verify that your tests and libraries are thread-safe with the Python 3.13 experimental freethreaded mode.” Testing your project for compatibility with freethreaded Python. Testing in single thread doesn't test that. Neither does testing with pytest-xdist, because it uses multiprocessing to parallelize tests. So, Ant and others “made this plugin to help you run your tests in a thread-pool with the GIL disabled, to help you identify if your tests are thread-safe.” “And the first library we tested it on (which was marked as compatible) caused a segmentation fault in CPython! So you should give this a go if you're a package maintainer.” Michael #4: pytest-edit A simple Pytest plugin for opening editor on the failed tests.

Michael #1: pyawaitable CPython API for asynchronous functions. by Peter Bierma It was originally designed to be directly part of CPython - you can read the scrapped PEP about it. Since this library only uses the public ABI, it's better fit outside of CPython, as a library. Brian #2: Annotated area charts with plotnine Nicola Rennie This is a marvelous, very professional looking plot, and a tutorial for how to achieve it. Uses plotline, which is “.. an implementation of a grammar of graphics in Python based on ggplot2” I actually didn't know the gg in ggplot came from “grammar of graphics”.

Brian #1: Joining Strings in Python: A "Huh" Moment Veronica Berglyd Olsen Standard solution to “read lines from a file, do some filtering, create a multiline string”: f = open("input_file.txt") filtered_text = "n".join(x for x in f if not x.startswith("#")) This uses a generator, file reading, and passes the generator to join. Another approach is to add brackets and pass that generator to a list comprehension: f = open("input_file.txt") filtered_text = "n".join([x for x in f if not x.startswith("#")]) At first glance, this seems to just be extra typing, but it's actually faster by 16% on CPython due to the implementation of .join() doing 2 passes on input if passed a generator. From Trey Hunner: “I do know that it's not possible to do 2 passes over a generator (since it'd be exhausted after the first pass) so from my understanding, the generator version requires an extra step of storing all the items in a list first.” Michael #2: 10 hard-to-swallow truths they won't tell you about software engineer job College will not prepare you for the job You will rarely get greenfield projects Nobody gives a BLANK about your clean code You will sometimes work with incompetent people Get used to being in meetings for hours They will ask you for estimates a lot of times Bugs will be your arch-enemy for life Uncertainty will be your toxic friend It will be almost impossible to disconnect from your job You will profit more from good soft skills than from good technical skills Brian #3: My thoughts on Python in Excel Felix Zumstein Interesting take on one person's experience with trying Python in Excel. “We wanted an alternative to VBA, but got an alternative to the Excel formula language” “Python runs in the cloud on Azure Container Instances and not inside Excel.” “DataFrames are great, but so are NumPy arrays and lists.” … lots of other interesting takaways.

For the second time in just a few months, we are talking Python on the Meta Tech Podcast. Python 3.12 features a whole range of new features, many of which were contributed by Meta. Carl and Itamar join Pascal to talk about their contributions to the latest release, including new hooks that allow for custom JITs like Cinder, Immortal Objects, improvements to the type system, faster comprehensions and much more. In their discussion, they talk not just about how and why those features were built but also the process of upstreaming and engaging with the community.  Got feedback?

You've probably heard the term "syntactic sugar", that is, syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use. It turns out Brett Cannon has spent 2 years diving into and writing about Python's sweet language features and how they really work down inside CPython. He joins me on the show today to dive into a few of the more relevant posts he's written about it.

A new build configuration flag, --disable-gil will be added to the configure script that will build CPython with support for running without the global interpreter lock. "In short, the SC accepts PEP 703, but with clear provisio: that the rollout be gradual and break as little as possible, that we can roll back any changes that turn out to be too disruptive – which includes potentially rolling back all of PEP 703 entirely if necessary (however unlikely or undesirable we expect that to be)." Removing the global interpreter lock requires substantial changes to CPython internals, but relatively few changes to the public Python and C APIs. The implementation changes can be grouped into the following four categories: Reference counting Memory management Container thread-safety Locking and atomic APIs Brian #4: Why is the Django Admin “Ugly”? Vince Salvino Some great quotes from the article: "The Django admin is not ugly, rather, no effort was made to make it a beautiful end-user tool.” - Ken Whitesell “The admin's recommended use is limited to an organization's internal management tool. It's not intended for building your entire front end around.” - Django docs “The Django admin was built for Phil.” - Jacob Kaplan-Moss “Even in the 0.9x days we used to have a image that said “Admin: it's not your app”.” - Curtis Maloney As Curtis put it, “encouraging people to build their own management interface, and treat admin as a DB admin tool, has saved a lot of people pain... the effort to customise it grows far faster than the payoffs.” Extras Brian: Local Conferences: Big Potential Michael: Data Science Jumpstart with 10 Projects course is out!

Understanding how your Python application is using memory can be tough. First, Python has it's own layer of reused memory (arenas, pools, and blocks) to help it be more efficient. And many important Python packages are built in natively compiled languages like C and Rust often times making that section of your memory opaque. But with Memray, you can way deeper insight into your memory usage. We have Pablo Galindo Salgado and Matt Wozniski back on the show to dive into Memray, the sister project to their pystack one we recently covered.

Brian #1: A Steering Council notice about PEP 703 (Making the Global Interpreter Lock Optional in CPython) Thomas Wouters Suggested by John Hagen “We intend to accept PEP 703, although we're still working on the acceptance details.” Moving forward in 3 stages short-term, no-GIL experimental build in 3.13 or 3.14 mid-term, declare support for no-GIL version long-term, no-GIL becomes default and remove any vestiges of the GIL No commitment and timeframe is nebuous long-term means 5+ years Need community support “We want to be able to change our mind if it turns out, any time before we make no-GIL the default, that it's just going to be too disruptive for too little gain.” Michael #2: Google's post-cookie world could turn into DRM for the internet A new authentication system could let websites block extensions or jailbroken devices. Google has been trying to implement plans to move beyond cookies for years without denying its partners the means to sell targeted ads. One recent proposal to guarantee user privacy and security could come at the cost of freedom of functionality. Comments are somewhat interesting. More info in a second article. Vivaldi has a response here. Brave won't ship with it. Brian #3: How ruff changed my Python programming habits Matthias Kestenholz “…there's always a trade off between development speed (waiting on git commit is very boring) and strictness. “ “ruff is so fast that enabling additional rules is practically free in terms of speed...” ruff has way more rules since last I checked. They are just mostly turned off by default. The article suggests a bunch to try turning on. See also ruff config settings turn on flake8-bugbear while leaving on defaults with select = ["E", "F", "B"] lots of rules to choose from ruff-pre-commit to run these with pre-commit Michael #4: pathlib api extended to use fsspec backends via Justin Flannery Expanding on the capabilities of fsspec, the same GitHub organization also supports another powerful library called universal_pathlib. universal_pathlib is a python library that aims to extend Python's built-in pathlib.Path api to use a variety of backend filesystems using fsspec. This seamless replacement allows developers to leverage the familiar and powerful pathlib API on any type of filesystem. upath.Path is a drop-in replacement for pathlib.Path and is an excellent addition to your toolkit.

How do Python virtual environments work under the hood? How does understanding these concepts help you with managing them for your projects? This week on the show, CPython core developer Brett Cannon returns to discuss his recent articles about virtual environments and the Python packaging landscape.

Are you familiar with the different versions of WebAssembly? Could WASM be the "write once, run everywhere" solution that developers have searched for? Where does distributing Python applications fit in the narrative? This week on the show, we have CPython core developer Brett Cannon to discuss his recent articles about WebAssembly and MVPy.

This week's EYE ON NPI will stick by your side like a faithful hound- it's the BeagleBoard.org BeaglePlay® Single Board Computer (https://www.digikey.com/en/product-highlight/b/beagleboard/beagleplay). Single Board Computers (SBCs) are like tiny computers that are less powerful than desktops but much better at booting quickly and interfacing with hardware. They also tend to run Linux or BSD because it's easier to get those OS's ported to new chipsets than convincing Apple or Microsoft! This new generation of SBC from BeagleBoard builds on their prior success with the BeagleBoard (https://www.digikey.com/short/1cmb3dtf) and BeagleBone (https://www.digikey.com/short/c52dpz47) by adding a ton more interfaces and connectors so many projects can be built with no soldering. Here's a bullet list to get us started: AM6254 SoC processor 16 GB eMMC storage 2 GB DDR4 memory Supports expansion with OLDI, 4-lane CSI, and QWIIC connectors CSI for compatibility with the BeagleBone AI-654, Raspberry Pi Zero W, and compute modules Full-size HDMI connector Small size: 8 cm x 8 cm USB Type-C® with 5 V @ 3 A input connector mikroBUS connector RJ45 Ethernet connector for Gigabit Ethernet Wi-Fi 2.4 GHz and 5 GHz capabilities BLE and SubG MicroSD slot USB Type-A connector at 480 Mbit Grove connector The main processor is the TI Sitara AM6254 (https://www.digikey.com/short/507rmwr2) with quad-core 64-bit A53 and a Cortex M4 coprocessor. This chip is paired with 2 GB of DDR4 RAM and 16 GB of eMMC storage for a powerful AI-ready chipset that has tons of onboard graphics support such as 1080P HDMI and 4 lanes of OLDI/LVDS. This chip has 9x UARTS, 5x SPIs, 6x I2C's, 3x PWM modules, 3x quad encoders, and 3x CAN-FD, and of course some GPIO. Note there's no ADC or DAC - you'd use SPI to connect those externally. Note this board doesn't have a 2x20 header like a Raspberry Pi, or even the dual header strips from the BeagleBone - but in exchange it stuffs a ton of hardware support directly onto the PCB. For example, if you'd like to add a camera, there's an onboard 22-pin 0.5mm pitch CSI FPC connector that is compatible with the Pi Zero camera cables (https://www.adafruit.com/product/5211) - use that adapter to interface with any low cost Pi Camera modules or compatibles. For video output, a vertical full-sized HDMI port will connect to any monitor or display. In fact we plugged in our desktop monitor and powered the Play with a USB wall adapter, and it immediately came up with an X desktop display. Mouse and keyboard can be added via the USB 2.0 socket, a mini hub will allow multiple devices since there's only one type A port. The BeaglePlay does a great job of including everything you may want to expand your Raspberry Pi with. For example, there's a BQ32002 Real Time Clock (https://www.digikey.com/short/p0h10jbq) with a CR1220 coin cell holder right on board - normally that would have to be included as a separate module. A microSD card slot can be used for storing large amounts of data: unlike most SBCs, there's onboard 16GB eMMC so you don't have to juggle SD cards to install the OS. There's also a ton of expansion ports! For I2C, the onboard QWICC (https://www.sparkfun.com/qwiic) JST SH connector lets you use the hundreds of SparkFun sensors as well as any Adafruit Stemma QT (https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma) devices. For UART/PWM/ADC/I2C/GPIO you can use the onboard Grove connector. Finally, for networking either to the Internet or to a sensor network, there's Gigabit Ethernet, WiFi 2.4G and 5G, BLE and Sub-G networking. Yeah that's a lot! It's almost all provided by the onboard TI SimpleLink CC1352P7 (https://www.ti.com/product/CC1352P7) which boasts support for 6LoWPAN, Amazon Sidewalk, Bluetooth 5.2 Low Energy, IEEE 802.15.4, MIOTY, Proprietary 2.4 GHz, Thread, Wi-SUN NWP, Wireless M-Bus (T, S, C, N mode), Zigbee. Note LoRa is not in there, so if you need LoRa that would be added with a separate module. There's also an RJ-11 with Single-Pair Ethernet (https://blog.adafruit.com/2020/08/27/eye-on-npi-harting-single-pair-ethernet-eyeonnpi-digikey-ethernet-digikey-harting-adafruit/) which makes this a good fit to connect to industrial robotics or automation. All this hardware is available at a great price of under $100 at Digi-Key, we already picked one up and we're going to try and get Blinka working on it (https://github.com/adafruit/Adafruit_Blinka) so that all of our CircuitPython libraries will 'just run' in CPython. Especially given the ready-to-run Stemma QT / Qwiic port on the side, this is an excellent board for a powerful but solder-free configurable SBC. Digi-Key has tons of BeaglePlay's stock for immediate shipment, so order today (https://www.digikey.com/short/jpztmq3w) and you will be playing with your new BeaglePlay by tomorrow afternoon.

What if we distributed CPython, the runtime, in the same way we distributed Python packages - as prebuilt binary wheels that only need to be downloaded and unzipped to run? For starters, that would mean we could ship and deploy Python apps without worrying whether Python itself is available or up-to-date on the platform. Nathaniel Smith has just proposed a PEP to do just that, PEP 711. And we'll dive into that with him next.

PyPy - Just in Time 27. Januar 2023, Jochen Warum ist der Python Interpreter eigentlich nicht selbst in Python geschrieben? Vor ziemlich genau zwanzig Jahren wurde ein Projekt gestartet, um das zu ändern.

Our code quality tools (linters, test frameworks, and others) play an important role in keeping our code error free and conforming to the rules our teams have chosen. But when these tools become sluggish and slow down development, we often avoid running them or even turn them off. On this episode, we have Charlie Marsh here to introduce Ruff, a fast Python linter, written in Rust. To give you a sense of what he means with fast, common Python linters can take 30-60 seconds to lint the CPython codebase. Ruff takes 300 milliseconds. I ran it on the 20,000 lines of Python code for our courses web app at Talk Python Training, and it was instantaneous. It's the kind of tool that can change how you work. I hope you're excited to learn more about it.

Brian #1: PEP 703 - Making the GIL Optional in CPython Author: Sam Gross Sponsor: Łukasz Langa Draft status, but on Standards Track, targeting Python 3.12 Suggested by: Will Shanks “The GIL is a major obstacle to concurrency.” Especially for scientific computing. PEP 703 proposes adding a --without-gil build configuration to CPython to let it run code without the global interpreter lock and with the necessary changes needed to make the interpreter thread-safe. PEP includes several issues with GIL and sckikit-learn, PyTorch, Numpy, Pillow, and other numerically intensive libraries. Python's GIL makes it difficult to use modern multi-core CPUs efficiently for many scientific and numeric computing applications. There's also a section on how the GIL makes many types of parallelism difficult to express. Changes primarily in internals, and not much exposed to public Python and C APIs: Reference counting Memory management Container thread-safety Locking and atomic APIs Includes information on all of these challenges. Distribution C-API extension authors will need access to a --without-gil Python to modify their projects and supply --without-gil versions. Sam is proposing “To mitigate this, the author will work with Anaconda to distribute a --without-gil version of Python together with compatible packages from conda channels. This centralizes the challenges of building extensions, and the author believes this will enable more people to use Python without the GIL sooner than they would otherwise be able to.” Michael #2: FerretDB Via Jon Bultmeyer A truly Open Source MongoDB alternative MongoDB abandoned its Open-Source roots, changing the license to SSPL making it unusable for many Open Source and Commercial Projects. The core of our solution is a stateless proxy, which converts MongoDB protocol queries to SQL, and uses PostgreSQL as a database engine. FerretDB will be compatible with MongoDB drivers and will strive to serve as a drop-in replacement for MongoDB 6.0+. First release back in Nov 2022 I still love you MongoDB ;) Brian #3: Four tips for structuring your research group's Python packages David Aaron Nicholson Not PyPI packages, but, you know, directories with __init__.py in them. Corrections for mistakes I see frequently Give your packages and modules terse, single-word names whenever possible. Import modules internally, instead of importing everything from modules. Make use of sub-packages. Prefer modules with very specific names containing single functions over modules with very general names like utils, helpers, or support that contain many functions. Michael #4: Quibbler Quibbler is a toolset for building highly interactive, yet reproducible, transparent and efficient data analysis pipelines. One import statement and matplotlib becomes interactive. Check out the video on the repo page.

Überhaupt hatten wir diesmal recht viele Abschweifungen und Nebenthemen drin. Aber gut, mit den Kapitelmarken sollte man die auch skippen können. Vielleicht dauert es ja auch nicht mehr so lang bis zur nächsten Episode

Where should you use an ellipsis in Python? How does it behave as a placeholder in a script, project, or stub file? What are the next goals for the Faster CPython project? This week on the show, Christopher Trudeau is here, bringing another batch of PyCoder's Weekly articles and projects.

PyPy is a fast, compliant alternative implementation of Python. cPython is implemented in C. PyPy is implemented in Python. What does that mean? And how do you test something as huge as an alternative implementation of Python? Special Guest: Carl Friedrich Bolz-Tereick.

It is a JavaScript framework that allows users to create Python applications in the browser using a mix of Python and standard HTML. The project's ultimate goal is to allow a much wider audience (for example, front-end developers) to benefit from the power of Python and its various libraries (statistical, ML/DL, etc.).” from a nice article on it, PyScript — unleash the power of Python in your browser PyScript is built on Pyodide, which is a port of CPython based on WebAssembly. Demos are cool. Note included in README: “This is an extremely experimental project, so expect things to break!” Michael #2: Memray from Bloomberg Memray is a memory profiler for Python. It can track memory allocations in Python code native extension modules the Python interpreter itself Works both via CLI and focused app calls Memray can help with the following problems: Analyze allocations in applications to help discover the cause of high memory usage. Find memory leaks. Find hotspots in code which cause a lot of allocations. Notable features:

C++ has exceptions, Python has exceptions. But they're not the same thing! How do exceptions work in CPython, how do we translate exceptions from C++ to Python (hint: it's different for direct bindings versus pybind11), and what do warnings (which we also translate from C++ to Python) have in common with this infrastructure?

Special guest: Anne Barela Brian #1: The Adam Test : 12 Questions for New Dependencies Found through a discussion with Ryan Cheley, who will be on an upcoming episode of Test & Code, talking about Managing Software Teams. The Joel Test dates back to 2000, and some of it is a bit dated. I should probably do a Test & Code episode or pythontest article on my opinions of this at some point. Nice shameless plugs, don't you think? The Joel Test is 12 questions and is a “highly irresponsible, sloppy test to rate the quality of a software team.” “The Adam Test” is 12 questions “to decide whether a new package we're considering depending on is well-maintained.” He's calling it “The Well-Maintained Test”, but I like “The Adam Test” Here's the test: Is it described as “production ready”? Is there sufficient documentation? Is there a changelog? Is someone responding to bug reports? Are there sufficient tests? Are the tests running with the latest language version? like Python 3.10, of course Are the tests running with the latest integration version? Examples include Django, PostgreSQL, etc. Is there a Continuous Integration (CI) configuration? Is the CI passing? Does it seem relatively well used? Has there been a commit in the last year? Has there been a release in the last year? Article has a short discussion of each. What score is good? That's up to you to decide. But these questions are good to think about for your dependencies. I also think I'll use these questions for my own projects. I've got a README.md, but do I need more examples in it? Should I have RTD docs for it? Have I updated the test matrix to include the newest versions of Python, etc? Have I hooked up CI? Michael #2: Validate emails with email-validator When you think about validating emails, you probably think regex (or just nothing) Regex is fine but so is this email: jane_doe@domain_that_doesnt_exist.com Problem is (at the time of the recording), domain_that_doesnt_exist.com is not a website. What about unicode variations that are technically the same but visually different? If the passed email address is valid, the validate_email() method will return an object containing a normalized form of the passed email address. Anne #3: The Python on Microcontrollers Newsletter One of my main focuses at Adafruit since the pandemic started is as editor of the Python on Microcontrollers Newsletter. With a weekly distribution of almost 9,400 subscribers, it's the largest newsletter of it's kind. It mainly focuses on CircuitPython and MicroPython and also discusses Python on single board computers (SBC) like Raspberry Pi. News about Python with a small computer emphasis Folks may subscribe by going to https://www.adafruitdaily.com/ which is separate from adafruit.com. The information is not sold or used for marketing and it's easy to unsubscribe (no “do you really want to do this, please reconsider…) The challenge, like for Python Bytes and other publications, is to find content. I scour the internet, with a bit of a focus on Twitter as I have an active account there. We encourage others to put in issues and Pull Requests on the newsletter GitHub, email information to cpnews@adafruit.com and using hashtag CircuitPython or MicroPython on Twitter. Brian #4: Git Organized: A Better Git Flow Annie Sexton Found through Changelog episode 480: Get your reset on A possible and common git workflow Branch off of a main branch to a personal dev branch Commit and Push during development to save your work When ready to merge, make a PR Problems Commits are hard to follow and messy, not ever really intended to separate parts of the workflow or anything. Commits are therefore useless in helping someone code review large changes. Annie's workflow Branch off of a main branch to a personal dev branch Commit and Push during development to save your work. But don't worry to much about commit messages, “WIP” is sufficient. Or a note to yourself. When ready to merge git reset origin/main Re-commit all changes in a logical order that makes more sense than the way the work actually happened. These will be several commits, with descriptive messages. Even partial commits, if there are unrelated changes in a file, work with this process Push all the new commits. (Is --force going to be necessary?) Create a PR. Now there are a set of commits that are actually helpful to break up large PRs into small chunks that tell a story. I'm looking to try this soon to see how it goes Michael #5: CPython issues moving to GitHub soon Update by The Python Developer in Residence, Łukasz Langa The Steering Council is working on migrating the data that is currently residing in Roundup at https://bugs.python.org/ (BPO) into the GitHub issues of the CPython repository hosted there. Laid out in PEP 581 -- Using GitHub Issues for CPython The ultimate goal is to move user- and core developer-provided issue-reporting entirely to Github. Each issue that currently exists on BPO will include metadata indicating where it was moved on Github. New issues will only exist on Github. Feedback, please: At the current stage, we're asking you to take a look at the links and important dates below, and share any feedback you might have. Timeline: Friday, March 11th 2022: Github starts transfer of the issues in the temporary repository to github.com/python/cpython/ . The migration is estimated to take anywhere from 3 to 7 days, depending on the load on Github.com. Anne #6: MicroPython, CircuitPython and GitHub What are Microcontrollers and Single Board Computers (SBCs)? Why not use CPython on Microcontrollers? MicroPython was originally created by the Australian programmer and theoretical physicist Damien George, after a successful Kickstarter backed campaign in 2013. Originally it only ran on a number of boards and was based on Python 3.4. CircuitPython was forked from MicroPython in 2017 by Adafruit Industries. Both MicroPython and CircuitPython are Open Source under MIT Licenses so adoption and modification by anyone is easy. Why fork CircuitPython? 1) Make a requirement that CircuitPython boards can enumerate to computers as a USB thumb drive to add or change code files with any text editor. 2) Aim to make CircuitPython use CPython library syntax whenever possible. 3) Make it easy to use and understand for beginners yet powerful for more advanced users. All CircuitPython code is on GitHub. GitHub Actions is used on repos like the Adafruit Learning System code to automate CI with Pylint, Black, and ensuring code has proper SPDX author and license tags, which is a new addition this year. Currently there are 283 microcontroller boards compatible with CircuitPython and 87 single board computers can use CircuitPython libraries in CPython via the Adafruit Blinka abstraction layer. Code portability between boards requires little if any changes. There are 346 CircuitPython libraries (all on PyPI / pip as well as GitHub) covering a wide range of hardware and real world needs. From blinking LEDs to using ulab (microlab), a subset of numpy, for data crunching. I just counted and there are exactly 1,000 Adafruit Learning System guides referencing CircuitPython, all free and open source/MIT licensed. https://learn.adafruit.com/ Extras Brian: Quick read: The Thirty Minute Rule, by Daniel Roy Greenfield summary: Stuck on a software problem for 30 min? Ask for help. Michael: The CircuitPython Show by Paul Cutler Follow up from my Python 3 == Active Python 3? James wrote: In episode #273, you guys were discussing supporting "Python 3" to mean any currently supported version of Python rather than "Python 3.7+" or similar. That's a really bad idea. There are still tons of people using unsupported versions of Python, and they're not all invalid use cases. For example, I am one of the upstream maintainers for cloud-init, and I was only recently able to remove Python 3.5 in order to make 3.6 our minimum supported version (which will continue for the next year). The reason is that our main consumers are downstream distro packagers (ubuntu, red hat, fedora, etc), and it's not uncommon for software released into long-term supported OS releases to be supported for 5-10 years or more. If I fire up an Ubuntu Trusty container, which still receives extended support until 2024, I get Python 3.4. So even though 3.4 is unsupported by Python upstream, it is still absolutely in use and supported by OS manufacturers. Joke: A case of the Mondays

The CPython interpreter has been the primary implementation of the Python runtime for over 20 years. In that time other options have been made available for different use cases. The most recent entry to that list is RustPython, written in the memory safe language Rust. One of the added benefits is the option to compile to WebAssembly, offering a browser-native Python runtime. In this episode core maintainers Windel Bouwman and Adam Kelly explain how the project got started, their experience working on it, and the plans for the future. Definitely worth a listen if you are curious about the inner workings of Python and how you can get involved in a relatively new project that is contributing to new options for running your code.

Trent Nelson is a software engineer working with Continuum Analytics and a core contributor to CPython. He started experimenting with a way to sidestep the restrictions of the Global Interpreter Lock without discarding its benefits and that has become the PyParallel project. We had the privilege of discussing the details around this innovative experiment with Trent and learning more about the challenges he has experienced, what motivated him to start the project, and what it can offer to the community.
