We were so lucky to have @lukasz.langa.pl as our very first Developer in Residence. I consider the program an incredible success story of what funding can do in open source. That is in large part a reflection of his hard work, and the amazing team of DiRs who followed. Thank you Łukasz!

Nearly 5 years, countless PRs, a program grown from 1 to 5. Thank you, Łukasz Langa, for defining the CPython Developer in Residence role. Best of luck on the next step of your journey and we'll see you around the community!

Any time I see something like this in a #Python REPL, I can't help but smile for two reasons: 1. Yes, yes I did forget. 🙈 2. I know some of the folks who worked so hard to make that message do exactly what I want it to do. Thanks to @pablogsal.com, @lukasz.langa.pl, and so many others! #OpenSource

Woo, everyone's favourite Python profiler just got async awareness! 🎉 With --async-aware, you'll be able to see parent-child task hierarchies instead of flat event loop stacks. Without vs. with:

Had a lot of fun working with @pablogsal.com on this one!! github.com/python/cpyth...

Oh boy, you can bet we are cooking the coolest profiler for Python 3.15 👨‍🍳🔥

Too much power 🔥🔥🔥🔥

🎙️ Bored this weekend? Part 2 of the interviews from the CPython core sprint in Cambridge UK is out. Don’t worry, it's shorter than Part 1. Only 2 hours 18 minutes! ✨ Hear from Greg, Thomas, Paul, Pradyun, Carol, Guido, Brett, Erlend, Tal, Lys, Yury, and Diego. creators.spotify.com/pod/profile/...

The core․py podcast is back with a new episode! Actually, it’s only half an episode, and yet it’s the longest one so far. We interviewed attendees sprinting on CPython at Arm Inc. Topics include: #Python 3.14 and 3.15, the future of free threading, and pizza. creators.spotify.com/pod/profile/...

🚀 Python 3.14 is out and so is 3.15 alpha! I chatted with @hugovk.dev, @pablogsal.com, and @lukasz.langa.pl about which release was the least successful, why release notes always say “and now for something completely different”, how Python actually gets released and many more! youtu.be/BHUWyM2cxwE

Thank you, @developer.arm.com, for investing in the future of #Python and the PSF by hosting this year’s CPython sprint– we appreciate your support!

Python 3.14 is out! 🎉 What goes on behind the scenes before a new Python version reaches us? I had the chance to chat with @hugovk.dev, @lukasz.langa.pl, and @pablogsal.com about their experiences as release managers. Sneak peek: youtu.be/yc9lpM_zpes, full episode coming next week!

🐍 Python 3.14 is here! 🎉 ✨ Template strings (t-strings) for safer string interpolation 🚀 Free-threaded Python officially supported (bye GIL!) 🎨 Syntax highlighting in the REPL 📦 Zstandard compression in stdlib 🔍 Remote PDB debugging Full release notes: docs.python.org/3.14/whatsne...

🐍🏃‍➡️🏃‍➡️🏃‍➡️🏃‍➡️ #Python #CoreSprint day 4! Finally, 3.14.0rc3: next RM @savannah.dev joined in to watch the process and ask questions 🥧 Then a quick core․py recording with @pablogsal.com and @lukasz.langa.pl before heading up to Manchester for #PyConUK! 🐝 Thanks again to @diegor.it and Arm for hosting! 🦾

Have you noticed? A new episode of the core․py podcast is out! This one is a little out there even for our standards, but it was a fun trip to go through all those PEPs and think “what if?” Also included: @pablogsal.com suffering some technical difficulties 🥸 creators.spotify.com/pod/profile/...

The Steering Council accepted @pablogsal.com's PEP 799! New `profiling` module: * `tracing`: deterministic function-call tracing (moved from cProfile) * `sampling`: new statistical sampling profiler Old `profile` deprecated discuss.python.org/t/pep-799-a-... #Python #profiling #PEP799 #Python315

@pablogsal.com @lukasz.langa.pl yesterday I asked my 2yo daughter if she wanted to listen to music or nerds while cooking dinner. She said "nuuurds" so we listened to core.py while we cooked.

📣📣 Keynote speaker announcement: Hynek Schlawack 🎤🎉 Hynek is been a pillar of the #Python community, exploring its internals & applications, and sharing his knowledge worldwide. At #PyConUK2025, he’ll be revealing Python’s secret superpower 🐍 We’re thrilled you’re joining us, @hynek.me ! 🌐 hynek.me

@pablogsal.com and I are in Prague for @europython.eu. Come talk to us about REPLs, parsers, profilers, and Sleep Tokens! 🤘🏻 And if you’re not here, there’s a new episode of the core․py podcast where we cover the new builtin sampling profiler for #Python 3.15 🏎️ creators.spotify.com/pod/profile/...

Modern sisyphus

Something will happened at @pycon.us in Ballroom B/C. 2:30 PM. 🍌 @1st1.dev

I’m officially a CPython Core Developer! 🐍 I’ve been using Python since 2006 — contributing back was a dream, and now it’s real. Huge thanks to everyone who supported me, and to Arm for backing me from day one. It’s not the destination — it’s the journey. 💙 🔗 discuss.python.org/t/vote-to-pr...

LHR ✈️ PIT See you at #pyconus2025 on the other side 🤘🐍

🎙️ NEW EPISODE ALERT! 🐍 We get our hands dirty with CPython’s reference counting, cycle detection, and why cleaning up your objects isn’t as simple as taking out the trash. creators.spotify.com/pod/profile/... Warning: May contain explicit technical details that Apple finds too hot to handle 😂

🎙️ Time for another episode of the core․py podcast! 🕹️ Are we finally covering the long-awaited topic of garbage collection? Well, no. @pablogsal.com wanted to talk about his PEP 768 instead. 🖍️ We also argue about syntax highlighting in PyREPL. #Python creators.spotify.com/pod/show/cor...

As someone who had the distinct pleasure of hanging out with all three of them together, I need to stress how much kudos they deserve for this episode not being 20 hours long.

It’s my birthday 🎁 and what best present than another episode of the core.py podcast? 🎙️This time we have @1st1.dev with us talking about velociraptors, unicorns and www.geldata.com! 🦄 Join us in this extra long episode with the best mic quality ever! creators.spotify.com/pod/show/cor...

It's been a while, huh? The core․py podcast is back with an episode about reference counting! 🎙️ I know y'all are waiting for the GC episode but we need to eat the veggies first. We hope it's fun anyway. We bet it is! 🍀 #Python #Podcast #Betting #TotallyLegal creators.spotify.com/pod/show/cor...

I’ve seen minds.md/zakirullin/c... being passed around & generally very much agree with it. It’s essentially a verbose version of my own mantra: “Complexity is not about how many keys I have to press – it’s about how difficult it is to reason about the consequences of what I’m doing.” 🧵 1/11

Believe me when I say this: it will be absolute 🍌🍌🍌🍌🍌🍌🍌🍌🍌 Join @pablogsal.com and I at PyCon US 2025.

We are very exited to share with you PEP 768 🐍, which proposes a safe external debugger interface to Python. We think this is a really exciting change that would allow debuggers and tools to safely attach to running Python processes without stopping or restarting them. 🔨🐛 peps.python.org/pep-0768/

Impressive, very nice. Let's see Paul Allen's Starter Pack

Once more I am humbled and honoured to serve in the Python 🐍 Steering Council 2025 with my amazing colleagues @pumpichank.bsky.social, @corona10.bsky.social, @emilyemorehouse.bsky.social and @gpshead.bsky.social Thanks to all of you for your trust and support 🙏🖤 I will do my best to serve! 🤘
