Libraries Run Rust Inside Python (With PyO3)

The blog post discusses how libraries can be run inside Python using PyO3, a Rust library that allows Python code to interact with Rust code. PyO3 provides a way to write libraries that can be used from Python, making it possible to use Rust's performance and concurrency features in Python projects. The author explains how to use PyO3 to create a simple Rust library that can be imported and used from Python, and provides an example of a Rust library that uses the `std::thread` module to run a function concurrently. The post also touches on the benefits of using PyO3, including the ability to write high-performance libraries that can be used with Python's high-level features.
