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. 💙 #Python #CPython
We are expanding the CPython team in the Runtimes organisation at @Arm, hiring Senior Software Engineers in Cambridge/Manchester. Love diving into CPython internals or improve its performance?🐍 Apply here:👇 careers.arm.com/job/cambridge/…
I just got back from @europython 2025! I spoke about the CPython JIT, mentored a new speaker, introduced the keynote, and connected with amazing people. Now even more proud to be part of this community 🐍💛 📖 Full recap on LinkedIn: linkedin.com/feed/update/ur…

It was great to see you folks and thanks for coming over!
In Cambridge today with @anthonypjshaw and @diegor!!! Here to learn more about the work we’re doing with Windows on @Arm and the work Diego is doing with the CPython JIT 🐍💕✨

🚀 My #MSBuild2025 session is live! Learn how CPython & PyTorch now build and run natively on Windows on Arm using GitHub-hosted runners, no cross-compilation needed! Watch here 👉 build.microsoft.com/en-US/sessions… #PyTorch #CPython #GitHubActions #Arm64
Just attended my first Python Language Summit! 🐍 A day full of fascinating discussions, ideas, and brilliant people. Grateful to be part of this amazing community.💙 #PyConUS


🔥 PyTorch native builds are now available for Windows on Arm! ✅ No x64 emulation 🚀 Faster performance 📦 Works on Surface Pro X, Dev Kits & GitHub Actions Dev workflows on Arm64 just got way better. 🔗 blogs.windows.com/windowsdevelop… @Microsoft #PyTorch #WindowsOnArm #ML #Arm64
This is indeed a great achievement! You can now build, validate, and deploy *natively* on Arm across Linux, macOS, and Windows. And the best part? It’s completely free for public repositories. What are you waiting for? Start building your software for @Arm today!
#ICYMI: We’ve been working closely with @ThePSF to make native Python compilation and validation easier than ever on GitHub Runners. In fact, Python is the first project on GitHub to enable support for Windows on Arm runners. 👏 Stay tuned - more to come!
Sending a big thank you to @Arm for providing ARM GitHub Action runners to CPython ahead of the public preview launch today! github.blog/changelog/2025… #python #cpython
BREAKING! Guido van Rossum, the creator of Python, has officially reinstated himself as Python’s Benevolent Dictator for Life - but this time, he’s bringing some new quirks with him. 👀 Stay tuned for our Python documentary this summer! 🐍🎬 Feat @gvanrossum , Barry Warsaw,…
I'm thrilled to announce that my proposal “Exploring the CPython JIT” has been accepted at @europython 🐍🚀 I look forward to sharing an in-depth look into the technical details of JIT compilation for CPython. See you at #EuroPython2025
