Python Free Threading: A Guide to GIL-Less Parallel Programming

By: Dantas Morais, Bruno Well

Unlock the full potential of your CPU with the new era of Python parallelism

With the release of Python 3.13 and with the experimental removal of the Global Interpreter Lock (GIL), the most popular language in the world now has support for free threads.
Python Free-Threading offers a roadmap to this paradigm shift. The book goes through some theory, but mainly the practice of parallel programming with multi-core Python threads.

What You Will Learn

Fundamentals: Concurrency, Parallelism, Processes, Threads, Speedup, Amdahl's Law.

Parallel Patterns: MapReduce, Message Passing, Producer-Consumer, and Actors.
