If in a few years no humans are writing code anymore, then this might be the last moment we truly get to enjoy it. So enjoy it fully and appreciate the present, so you won’t look back with regret in the future.

I hope that it would be useful to people in practice :)

As of Python 3.15, you can also annotate mmap calls made from pure Python code using the mmap.set_name() method.

Oh please, just don’t launch the new model at dawn in Korea… 😂

2025년에 이어 2026년에도 파이썬 운영위원회 (Python Steering Council ) 멤버로 활동하게 되었습니다. 파이썬 코어팀이 올해 집중해오던 프로젝트들의 모멘텀을 계속 유지하기 위해서 노력하겠습니다.

I would also like to express my sincere appreciation to this year’s members, @gpshead.bsky.social and @emilyemorehouse.bsky.social , who supported me greatly as a new member.

Thank you all for your continued support and trust.

I look forward to continuing to serve the community and helping guide Python’s technical direction in the coming year.
I also look forward to helping strengthen connections between the Python core team and communities in under-represented regions.

I am truly grateful for the opportunity to serve alongside and collaborate with such amazing colleagues on the Python Steering Council: @pumpichank.bsky.social , @pablogsal.com , @savannah.dev , and @yhg1s.bsky.social.

I am very happy to continue serving as a member of the Python Steering Council next year as well.

As I mentioned in my self-nomination, I will work to maintain and build on the momentum that the Python core team has driven this year.

I’m looking forward to working alongside my fellow council members to serve the community, support contributors, and help guide Python over the next year. Congratulations @pablogsal.com @yhg1s.bsky.social @pumpichank.bsky.social @corona10.bsky.social! 🎉

Starting in Python 3.15, anonymous mmap usage will be annotated on Linux (kernel version >= 5.17) when the interpreter is launched with -X dev.
Annotated names are shown in /proc/<pid>/maps, which can help with debugging :)

New Marco!

얼마 전에 나온 파이썬 다큐맨터리에 한국어 자막이 추가가 되었습니다. 아직까지는 유일한 수동 번역된 비영어 자막입니다. 이 작업을 위해 노력해주신 @pycon.kr 분들께 감사를 드립니다!

Very proud that official Korean subtitles is added to “Python: The Documentary” thanks to the amazing effort from
@pycon.kr

It’s the only non-English language with manually created subtitles, not auto-generated.

I am also grateful that I can get positive energy from you everytime.

The passing car meme but with Hugo's github handle

Going to report a bug literally any Python project on GitHub to find @hugovk.dev already got there before you, reported it and fixed it. Every time.

Most of my recent OSS contributions are connected to projects at my company, even if the contributions are small or simple. So I still believe the best way to start contributing to open source is by working on, or aligning with, your day-to-day projects :)

Sometimes it is good to try to keep a distance from the topic that I am biased on

Make no-opt JIT to pass whole unit test. · Issue #137838 · python/cpython #137800 (comment) While investigating, make JIT thread-safe for FT build. IMO, we should separate this task into making the tier 2 interpreter thread-safe (with optimzation disabled) and the optimi...

During the CPython core sprint, I was glad to close the issue by fixing it so that the JIT can now pass unittests without any optimizations(no-opt). This will be the basic step to make the JIT compatible with free-threading.

I hope we can have more CPython sprints happening across various regions!

It’s been a while, but I finally had a full day at work to spend on open source. Happy to dig into some long-pending CPython issues, especially since most of my days lately are just paperwork.

Hopefully no more paper works after next month

Side note: It is not Python, but learning something from outside is a good practice that I am using :)

Yesterday I joined @bernsteinbear.com for live debugging for my stuck PR on his JIT project, and it was an outstanding experience. Learning directly from people like him is priceless, and I truly hope more mentors like this can have greater impact in the community.

I got a new t-shirt :)
