PyO3 101 - Writing Python modules in Rust
summary
Step‑by‑step demo of setting up a Cargo project setup and adding PyO3 to produce a native Python extension written in Rust, with live code that builds a small library, imports the compiled module in Python, and runs its functions. Covers writing Python‑callable Rust functions and modules, mapping Rust errors to Python exceptions, converting common types (strings, lists, tuples), and shows the rebuild and import cycle so the extension actually works on a local machine.
