Ruff. uv. Polars. Pydantic. Pyrefly. Granian. Every one of them is written in Rust. The code that used to be C when Python needed speed is increasingly Rust. Our new course, Up and Running with Rust, is the Python developer's fast track into that world. Every Rust idea is taught next to its Python equivalent: fn vs def, crates vs PyPI, Cargo vs uv, borrow checker vs GC. You finish by building a Rust extension with PyO3 and calling it from Python. https://training.talkpython.fm/courses/up-and-running-with-rust #Python #Rust
