use std::os::raw::{c_char, c_int};
use std::ffi::CString;
use libc::{c_double, c_void};
#[link(name = "python3.8")]
extern "C" {
fn Py_Initialize();
fn Py_Finalize();
fn Py_BuildValue(format: *const c_char, ...) -> *mut c_void;
}
fn main() {
unsafe {
// 初始化 Python 解释器
Py_Initialize();
// 构建一个 Python 元组对象，并打印它
let x = 1.23 as c_double;
let y = 4.56 as c_double;
let format = CString::new("dd").unwrap().as_ptr();
let result = Py_BuildValue(format, x, y);
let s = CString::from_raw(result as *mut c_char).into_string().unwrap();
println!("{}", s);
// 关闭 Python 解释器
Py_Finalize();
}
}
