Simply create a new .py file in the same folder as your main Python code. Then “import” that file as you now know how to do, then access the functions from within that module.

Cython generates the second kind of module: C libraries that talk to Python’s internals, and that can be bundled with existing Python code. Cython code looks a lot like Python code, by design.

You’ll learn how to set up a Python project with a PyO3 create, how to expose Rust functions as a Python module, and how to create Python objects like classes and exceptions in Rust.
