These macros now support specifying an argument list: `py_fn!(myfn(myarg: i32))` will expect `myfn` to be a function with the signature: `fn myfn<'p>(py: Python<'p>, myarg: i32) -> PyResult<'p, _>` It can called from python as `myfn(1)` or using keyword arguments: `myfn(myarg=1)`. If no parameter list is specified (`py_fn!(myfn)`), the expected signature now includes the keyword arguments: `fn run<'p>(py: Python<'p>, args: &PyTuple<'p>, kwargs: Option<&PyDict<'p>>)` Due to the additional `kwargs` argument, this is a [breaking-change]. |

version = "*"
Example program displaying the value of sys.version
:
extern crate cpython;
use cpython::{PythonObject, Python};
use cpython::ObjectProtocol; //for call method
fn main() {
let gil = Python::acquire_gil();
let py = gil.python();
let sys = py.import("sys").unwrap();
let version: String = sys.get("version").unwrap().extract().unwrap();
let os = py.import("os").unwrap();
let getenv = os.get("getenv").unwrap();
let user: String = getenv.call(("USER",), None).unwrap().extract().unwrap();
println!("Hello {}, I'm Python {}", user, version);
}
