How many attempts have been made to remove Python's Global Interpreter Lock (GIL)? How do they compare to the current approach? Christopher Trudeau is back on the show this week with another batch of PyCoder's Weekly articles and projects.
👉 Links from the show:
Christopher shares a recent article about Thomas Wouters' talk at PyCon US 2026. The talk, titled "Free-threaded Python: past, present, and future," covers the efforts to remove the GIL starting in 1996. He explains that threads are complex, but they allow multiple tasks to run concurrently within a single process and its address space.
The GIL is how CPython implements threading. The GIL protects Python objects and their reference counts, which determine the current objects in use. The talk also looks forward and shares the current work to remove the GIL, now named free-threaded Python, and the goals for the near future.
We also share other articles and projects from the Python community, including community announcements, a roundup of recent Real Python tutorials and video courses, using `uv` in Production, employing Wagtail as Django admin on steroids, managing and measuring Python code quality, a pure-Python implementation of `jq`, and a project to bring interactivity to plotnine.
