This week we’d love to spotlight Diego Russo , a member of the Programme Team, and his contributions to EuroPython 2026. In addition to helping ensure an interesting and varied conference programme, Diego was our liaison with Guido van Rossum, Łukasz Langa and Pablo Galindo Salgado who gave a very fun keynote session a
Hey, did you miss me? I've only published two blog posts in the past two months because I was busy writing 10+ blog posts detailing the Python Language Summit in 2026 . If you are interested in the Python programming languages' technical direction ( or you just really miss my writing ) go over to the Python Insider and
Do you know what's actually slow in your Python app? Or are you guessing? Until now, profiling Python meant a tracing profiler that made your code 2 to 3 times slower. Or a third-party tool that broke with every new release. Python 3.15 fixes that. It ships Tachyon, a sampling profiler built into the standard library.
Python 3.15 ships with a new profiler. It is called Tachyon, it lives in the standard library as the profiling.sampling module, and unlike cProfile it is a sampling profiler rather than a tracing one. I now have a set of hands-on workshops for it, which you can find at github.com/GrahamDumpleton/tachyon-workshops or on
Security updates across Python 3.10–3.14, the final maintenance release of 3.13, and a farewell to Python 3.10.
The 2026 Python Language Summit was hosted in Kraków, Poland as part of EuroPython 2026. There were 15 talks covering free-threading, Rust, garbage collection, type annotations, and more.
Lightning talks on a one-time ABI break, safer interruptions, EktuPy (Scratch but Python), an AGENTS.md file for CPython, and a call to read PEP 836.
Tobias Wrigstad, Fridtjof Stoldt, and Donghee Na propose a safe and performant, high-level concurrency model for free-threaded Python
Petr Viktorin gives an update on the Developer-in-Residence role and asks Python core developers for projects to prioritize
Kushal Das shows off Spicycrab, a Python-to-Rust transpiler for Python users who need performance without learning Rust or leaving Python
David Hewitt shares a status update, first module, and potential acceptance criteria for the Rust for CPython project
