How can I integrate Rust with Python?

You can integrate Rust with Python using the PyO3 or rust-cpython libraries. Would you like a code example?

Yes, please provide a simple example using PyO3.

Sure! First, you'll need to create a new Rust library. In your Cargo.toml, add pyo3 as a dependency. Then, write a simple function in Rust and expose it to Python.

What does the Rust code look like?

Here's a simple example:

use pyo3::prelude::*;

#[pyfunction]
fn add(a: usize, b: usize) -> usize {
    a + b
}

#[pymodule]
fn mymodule(py: Python, m: &PyModule) -> PyResult<()> {
    m.add_function(wrap_pyfunction!(add, m)?)?;
    Ok(())
}

How do I call this function from Python?

After building your Rust library, you can call it in Python like this:

import mymodule
result = mymodule.add(5, 3)
print(result)  # Output: 8
