Python’s Preprocessor
Every now and then you hear outrageous claims such as “Python has no preprocessor”. This is simply not true. In fact, Python has the best preprocessor of all languages - it quite literally allows us to do whatever we want, and a lot more. It’s just a little tricky to (ab)use. Python source code encodingsThanks to PEP-0263 it is possible to define a source code encoding by placing a magic comment i
Rye and uv: August is Harvest Season for Python Packaging
written on August 21, 2024 It has been a few months since I wrote about Rye here last. You might remember that in February I passed over stewardship of my Rye packaging too to Astral. The folks over there have been super busy in building a lot of amazing tooling for Python packaging in the last few months. If you have been using Rye in the last few months you will have noticed that the underlying
uv: Unified Python packaging
TL;DR: uv is an extremely fast Python package manager, written in Rust. We first released uv in February as a drop-in replacement for common pip workflows. Today, we're announcing a series of features that extend uv beyond a pip alternative, and into an end-to-end solution for managing Python projects, command-line tools, single-file scripts, and even Python itself. It's Cargo, for Python: a unifi
500 Python Interpreters
🐍 No Steppy On Threads 🐍August 19, 202417 minutes As we approach the final release date for Python 3.13, I’ve seen an uptick in discussion regarding 3.13’s introduction of an optional GIL. While removing the GIL has been a long time coming for the average user (I’ve dreamt of this for nearly 20 years), there have actually been two concurrent efforts to improve Python’s performance for multithrea

GitHub - igrek51/wat: Deep inspection of Python objects
Deep inspection of Python objects. WAT is a powerful inspection tool designed to help you explore unknown objects and examine them at runtime. "Wat" is a variant of the English word "what" that is often used to express confusion or disgust If you ever find yourself in a Python console, feeling lost and confused, and wondering "WAT? What is this thing?", that's where wat inspector comes in handy. L

Free-threaded CPython is ready to experiment with!Published July 12, 2024 First, a few announcements: Yesterday, py-free-threading.github.io launched! It's both a resource with documentation around adding support for free-threaded Python, and a status tracker for the rollout across open source projects in the Python ecosystem. We hope and expect both of these to be very useful, with the status tra
Rye
Welcome User Guide Community Changelog Philosophy Note Rye is no longer developed. We encourage all users to use uv, the successor project from the same maintainers, which is actively maintained and much more widely used. For current Rye users, please see the uv migration guide. While Rye will continue to be available, no further updates are planned, including security updates. Rye is a comprehens
Python has too many package managers
Python is a wonderful programming language. I’ve used it to build webapps, deep learning models, games, and do numerical computation. However there is one aspect of Python that has been an inexcusable pain-in-the ass over many years. That would be the fragmented Python package and environment management ecosystem, succinctly represented by the following XKCD comic: You see, a lot of other programm
