  #[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();
      }
