Rust-powered: Two new Python tools to watch

This week in Python brings us a toe-to-toe showdown between two Rust-powered Python type checking tools. We also have a gentle introduction to type hinting, a look at the perils—and promises—ahead for a free-threaded, no-GIL Python, and a shocking exposé (okay, just kidding) of the latest malware attacks targeting machine learning developers, this time delivered via PyPI.

A free-threaded, no-GIL Python promises real concurrency, at long last. But what side-effects will come with that freedom? And how can we start fixing them now?
