Function py_push_arg 

pub fn py_push_arg<'a, 'py, T>(
    py: RUMPython<'py>,
    py_args: &mut RUMPyList,
    arg: &T,
) -> RUMResult<()>
where
    T: FromPyObject<'a, 'py> + IntoPyObject<'py> + Debug + Clone,

Push argument of type T into instance of Python List. We can then use the list to pass arguments to Python function or method.

Example

    use compact_str::format_compact;
    use pyo3::Python;
    use pyo3::types::{PyListMethods, PyAnyMethods};
    use crate::rumtk_core::scripting::python_utils::{py_new_args, py_push_arg, RUMPyArgs, RUMPyList};
    use crate::rumtk_core::scripting::python_utils::{py_buildargs, py_extract_string_vector};


    Python::attach( |py| {
            let example_arg_1 = 1;
            let example_arg_2 = "Hello";
            let mut py_args: RUMPyList = py_new_args(py);
            py_push_arg(py, &mut py_args, &example_arg_1.clone()).unwrap();
            py_push_arg(py, &mut py_args, &example_arg_2.clone()).unwrap();
            let arg_1: usize = py_args.bind(py).get_item(0).unwrap().extract().unwrap();
            assert_eq!(&example_arg_1, &arg_1, "{}", format_compact!("Python list does not match the input list!\nGot: {:?}\nExpected: {:?}", &arg_1, &example_arg_1));
        }
    )
