# Usage

[`cpython` is available on crates.io](https://crates.io/crates/cpython) so you can use it like this (in your `Cargo.toml`):

```toml
[dependencies.cpython]
version = "*"
```

Example program displaying the value of `sys.version`:

```rust
extern crate cpython;

use cpython::{PythonObject, Python};

fn main() {
    let gil_guard = Python::acquire_gil();
    let py = gil_guard.python();
    let sys = py.import("sys").unwrap();
    let version = sys.get("version").unwrap().extract::<String>().unwrap();
    println!("Hello Python {}", version);
}
```
